What is glaucoma?

Published

on

Glaucoma is an eye disease in which fluid pressure increases within the eye; if left untreated, the patient can lose sight and even become blind.

Glaucoma is relatively common and can cause damage to the optic nerve if left untreated, particularly in older adults.

In this post, we’ll discuss the causes, symptoms, and glaucoma treatment. We will also clarify the various types of possible surgical procedures.

Fast facts on glaucoma:

  • Glaucoma has been called the silent thief of sight.
  • The main types of glaucoma are open-angle and closed-angle.
  • Age and thyroid problems increase the risk of glaucoma.
  • Symptoms can include severe eye pain.
  • Treatment includes surgery and medications.

What is glaucoma?

In short, glaucoma is a build-up of pressure that causes damage to the optic nerve inside the eye.

In the front of the eye there is a small space, called the anterior chamber. This fluid nourishes and bathes surrounding tissues. Clear liquid flows in and out of the anterior chamber. When a patient has glaucoma the fluid drains out of the eye too slowly. This contributes to build-up of blood, which increases pressure within the eye.

If this pressure is reduced and regulated, the optic nerve and other sections of the eye can get weakened, causing vision loss.

Though one may be more seriously affected than the other, the disease generally affects both eyes.

Treatments for glaucoma

Treatments include either increased fluid flow from the eye, decreasing it’s production or both:

Eyedrops for glaucoma

Eyedrops are a common and effective treatment for glaucoma.

In most cases, initial glaucoma treatment involves eye droplets.

Compliance is vital to best results and to prevent harmful side effects – that means carefully following the instructions of the doctor.

Examples of eyedrops include:

  • prostaglandin analogues
  • carbonic anhydrase inhibitors
  • cholinergic agents
  • beta blockers

Side effects of eye drops may include stinging, redness, eyelash growth, eye color change and sometimes retinal detachments and breathing difficulties. If eyedrops are not adequately successful the doctor may prescribe an inhibitor of oral carbonic anhydrase.

Side effects are less when consumed in the course of meals. Initial side effects may include tingling in the fingers and toes, and frequent urination – but they usually improve within a few days.

Less often, when drinking fizzy drinks, there is a risk of rashes, kidney stones, stomach ache, weight loss, impotence, tiredness and a weird taste.

Causes of glaucoma

Doctors are uncertain about the exact causes of glaucoma but there are two categories of cases:

  • Primary glaucoma – this means that the cause is unknown.
  • Secondary glaucoma – the condition has a known cause, such as a tumordiabetes, an advanced cataract, or inflammation.

There are several risk factors for glaucoma:

  • Old age.
  • Ethnic background – East Asians, African Americans, and those of Hispanic descent have a higher risk of developing glaucoma, compared with Caucasians.
  • Some illnesses and conditions – like diabetes or hypothyroidism.
  • Eye injuries or conditions.
  • Eye surgery.
  • Myopia (nearsightedness).

Corticosteroids

Long-term corticosteroid patients have an increased risk of developing different conditions like glaucoma. With eye drops containing corticosteroids the risk is even greater.

Types of glaucoma

Glaucoma is one of the most common eye diseases.

There are two main types: open-angle and closed-angle glaucoma.

Closed-angle glaucoma (acute angle-closure glaucoma)

That may happen suddenly; the patient normally experiences pain and rapid loss of vision.

Fortunately, the signs of pain and discomfort make the patient seek medical attention, which leads to timely care, which typically avoids any permanent damage.

Primary open-angle glaucoma (chronic glaucoma)

The form is progressing very slowly. The patient may experience no symptoms; even slight vision loss can go unnoticed. Many people don’t get medical attention with this form of glaucoma until there has already been irreversible damage.

Low-tension glaucoma

It is a more unusual type of glaucoma not well understood by experts. While eye pressure is normal, it still causes damage to the optic nerves. This may be attributed to insufficient flow of blood to the optic nerve.

Pigmentary glaucoma

This form of open angle glaucoma develops usually during early or middle adulthood. Within the eye are scattered pigment cells that originate from the iris. If these cells build up in the channels that drain fluid from the eye, they can disrupt the normal fluid flow in the eye, causing eye pressure to rise.

What are the symptoms of glaucoma?

There are very specific signs and symptoms of primary open-angle glaucoma and acute angle-closure glaucoma:

Symptoms of primary open-angle glaucoma

  • Peripheral vision is gradually lost. This nearly always affects both eyes.
  • In advanced stages, the patient has tunnel vision.

Symptoms of closed angle glaucoma

  • Eye pain, usually severe.
  • Blurred vision.
  • Eye pain is often accompanied by nausea and sometimes vomiting.
  • Lights appear to have extra halo-like glows around them.
  • Red eyes.
  • Sudden, unexpected vision problems, especially when lighting is poor.

Surgery for glaucoma

If medications don’t work, or if the patient can’t handle them, the alternative could be surgical intervention. Typically the aim of the surgery is to bring down the pressure inside the eye. Examples of the operations include:

  • Trabeculoplasty – a laser beam is used to unblock clogged drainage canals, making it easier for the fluid inside the eye to drain out.
  • Filtering surgery (viscocanalostomy) – this may be carried out if nothing else works, including laser surgery. Channels within the eye are opened up to improve fluid drainage.
  • Drainage implant (aqueous shunt implant) – this option is sometimes used for children or those with secondary glaucoma. A small silicone tube is inserted into the eye to help it drain out fluids better.

Acute angle-closure glaucoma

Acute glaucoma to the angle closure is regarded as a medical emergency. Drugs which reduce pressure are administered immediately. Typically a laser procedure is performed that produces a tiny hole in the iris that allows fluids to move through the trabecular meshwork (the eye drainage system)-this procedure is called an iridotomy.

Even if only one eye is affected, the doctor can wants to treat both because the other eye is often affected by this type of glaucoma too.

Prevention

There is no known way to avoid glaucoma, but recognizing it early means treating it more efficiently, and reducing vision loss. Since, sometimes, there are no signs, it’s important to get your eyes checked regularly; particularly for those at higher risk.

For example, older adults, people of African or Hispanic descent and people with diabetes should be checked every year or 2 years after age 35. Tell your doctor how often you will get a check-up.

Allergy

Allergic conjunctivitis: What to know

Published

on

When a person’s eyes come into touch with an allergen, a chemical that causes the body’s immune system to respond, allergic conjunctivitis develops.

The eye gets inflamed and painful. The overactive immune system causes the body to produce histamine and other active compounds through mast cells, resulting in symptoms. The nerve terminals are irritated when blood vessels dilate or expand. As a result, the amount of tears secreted increases.

Infectious conjunctivitis differs from allergic conjunctivitis. The causes are not the same.

Causes

When the immune system overreacts to a substance, an allergic response occurs. The majority of people do not react to dust, pollen, or other substances in this way, but other people are more sensitive.

Allergens that typically cause allergic conjunctivitis include:

  • eye drops
  • make-up
  • pollen, as in hay fever
  • animal fur
  • dust mites.

Types

There are different types of allergic conjunctivitis.

1) Seasonal allergic conjunctivitis or allergic rhinoconjunctivitis

Pollen disease
Allergy conjunctivitis is frequently caused by pollen.

In regions with cold winters, pollen is the most prevalent allergen that causes conjunctivitis.

Other symptoms of pollen-induced conjunctivitis include sneezing, an itchy, clogged, or runny nose, and itchy, watery eyes.

Hay fever is also known as seasonal allergic conjunctivitis or allergic rhinoconjunctivitis.

It generally takes place in the spring and summer. Plants, particularly grass, trees, and flowers, are in pollen during this time. Some people get symptoms in the early autumn.

2) Contact conjunctivitis

Cosmetics, eyedrops, or other chemicals that irritate the conjunctiva in people who are vulnerable induce symptoms known as contact dermatoconjunctivitis. An allergic reaction occurs when these compounds come into contact with the body. Some people are hypersensitive to certain chemicals.

After the substance comes into contact with the eyes, symptoms generally appear 2 to 4 days later.

3) Papillary conjunctivitis (giant papillary conjunctivitis)

This is a common side effect of wearing contact lenses. Contact lenses can be uncomfortable for some people. This might grow worse and more unpleasant with time, causing the eyes to become red.

When a person wears hard contact lenses following eye surgery, giant papillary conjunctivitis (GPC) can develop.

Infections of the eye can be caused by poor hygiene when handling contact lenses, solutions, and cases.

4) Perennial conjunctivitis

Perennial conjunctivitis is a kind of conjunctivitis that lasts all year. It is mostly caused by an allergy to home dust mites. These tiny insect-like critters like to reside in bedding, upholstered furniture, and carpets.

Dust mites feed on human skin cells and like warm, damp people.

An allergic reaction to a particular dust mite protein is known as dust-mite allergy. Conjunctivitis, a clogged or runny nose, sneezing, and airway tightness, as seen in asthma, are all symptoms of this.

Animal dander, minute scales from animal skins or hair, and bird feathers are among the other causes. Some people may experience an allergic response to them.

Treatment

symptom of conjunctivitis
Conjunctivitis is characterized by pink or red eyes.

The following suggestions may help:

  • Cold compresses: The eyes can be soothed by placing a wad of cotton wool soaked in cold water on the eyelid.
  • Avoiding the allergen: Staying indoors while the pollen count is high, keeping the house clean, and limiting soft furnishings can all help.
  • Contact lenses should be avoided at all costs: These should not be used until all symptoms have vanished. After using any eye medicine, wait at least 24 hours before putting contact lenses back on.
  • Artificial tears: These eye drops dilute the allergen and help remove it.
  • Refraining from rubbing the eyes: Rubbing might aggravate the irritation. It’s tempting to touch inflamed eyes, so this might be challenging.

Antihistamines, mast cell stabilizers, and corticosteroids are used to treat the condition.

Antihistamines

Antihistamines, taken orally or as eye drops, may provide quick relief from symptoms. Histamines are blocked by antihistamines. When the immune system responds to a foreign substance, histamines are produced.

Cetirizine, fexofenadine, and loratadine are oral antihistamines used to treat allergic conjunctivitis. Once a day is generally plenty. Alaway and Zaditor are antihistamine eye drops. The eye drops will aid with eye problems, but the oral dose will help with a runny nose and other symptoms as well.

Azelastine, emedastine, and ketotifen are the most regularly prescribed antihistamine eye drops. They’re used twice or three times a day on the eyes.

Some antihistamines might make you sleepy. People who are taking them for the first time should avoid driving or using heavy machinery until they know how they will react to the drug.

Mast cell stabilizers

Mast cell stabilizers take longer to operate than antihistamines, but their effects stay longer once they do.

Lodoxamide and nedocromil are the most often used mast cell stabilizers. They are available as eye drops.

Antihistamines and mast cell stabilizers are used by certain patients. Before the mast cell stabilizers start acting, the antihistamines give some relief from symptoms.

Corticosteroids

These are only used in extreme cases and are rarely prescribed. The adrenal cortex produces corticoid, a steroid hormone. Synthetic corticosteroids are a type of drug that can reduce swelling and suppress the immune system.

Corticosteroids are effective, but they should be taken with caution and only for a short period of time due to the risk of adverse effects.

Symptoms

The majority of people who suffer from allergic conjunctivitis have issues with both eyes.

Symptoms may occur rapidly after coming into touch with the allergen in the eyes. Symptoms may develop after 2 to 4 days in other circumstances, such as when eye drops cause a response.

The following are some of the signs and symptoms of allergic conjunctivitis:

  • Eyelids swollen: When the conjunctiva becomes inflamed or if the person rubs their eyes a lot, the eyelids may puff up.
  • Soreness: The inflammation may cause pain and tenderness throughout the affected area. Some people describe the pain as burning.
  • Red or pink eyes: As the capillaries, or small blood vessels, in the conjunctiva widen, the eyes become irritated.
  • Pain: One or both eyes may be affected. If a person has painful, red eyes, is light sensitive, or has vision problems, they should see a doctor right away.
  • Itchiness: Itching may occur as the eyes become irritated. Rubbing can aggravate the itching.

Seasonal allergic conjunctivitis affects people at specific seasons of the year, generally from early spring to summer and occasionally into fall.

Perennial allergic conjunctivitis patients are vulnerable at any time of year. They could notice that their symptoms are more severe at some times of the day than at others.

Contact conjunctivitis can be identified by red, cracked, or dry eyelids. The symptoms of contact conjunctivitis and giant papillary conjunctivitis are not seasonal, and they can appear at any time of year.

Diagnosis

A doctor will examine the patient and inquire about signs and symptoms such as sneezing and a runny nose to diagnose allergic conjunctivitis.

Other conditions with comparable symptoms may need to be ruled out as well.

Anyone experiencing the following symptoms should contact a doctor right once, since they might be signs of a more serious problem:

  • vision problems
  • very red eyes
  • painful eyes
  • sensitivity to light, or photophobia

Aside from allergic conjunctivitis, the following disorders can cause redness in the eyes:

  • Keratitis: The cornea gets irritated and ulcerated on occasion. It can sometimes lead to corneal scarring, resulting in irreversible vision loss.
  • Iritis: Iris inflammation is a condition in which the iris becomes inflamed. The iris may cling to the lens if left untreated, limiting critical fluid outflow from the pupil. It’s possible that irreparable eye damage will develop.
  • Infective conjunctivitis: This is caused by bacteria or virus. It’s possible that it’s caused by the herpes virus, and it might signify a sexually transmitted infection (STI).
  • Acute glaucoma: In the eye, pressure builds up. Symptoms might emerge quickly. Acute glaucoma, if left untreated, can result in irreversible visual loss.

Complications

The doctor will also look to see if the discomfort is caused by an item or substance, such as an eyelash.

If the patient’s symptoms are severe or worsening, the doctor may recommend them to an ophthalmologist, or eye specialist.

After recent eye surgery, anyone who gets papillary conjunctivitis will be sent to an ophthalmologist. To ensure that therapy is effective, the eye or eyes must be closely monitored.

Complications of allergic conjunctivitis, whether chronic or seasonal, are uncommon.

Allergic conjunctivitis can have a negative influence on a person’s quality of life, although it seldom has a long-term effect on health.

Dermatoconjunctivitis and large papillary conjunctivitis can also cause complications.

It’s possible that the cornea will get inflamed. Keratitis is a condition that causes ulcers to grow on the cornea. This raises the danger of scarring and the chance of vision loss for the rest of one’s life.

Keratitis symptoms include:

  • blurred vision
  • a feeling that there is something in the eye
  • watery eyes
  • intense pain in the eye
  • sensitivity to light

If any of these symptoms appear, the person should seek medical attention.

Prevention

Finding out what causes allergic rhinitis and avoiding the allergen is the best method to prevent it.

Pet fur and pollen are two common allergies.

If your pet is the source of your allergy, try the following:

  • wash their bedding regularly
  • brush them regularly and wash them every 2 weeks
  • keep pets out of the bedroom

If you’re going to a residence with a pet, taking an antihistamine one hour ahead of time may help alleviate symptoms.

If pollen causes an allergic response, do the following:

  • use wraparound sunglasses to protect your eyes
  • bathe and change your clothes after being outside
  • try to get someone else to cut the lawn for you
  • stay inside and keep doors and windows closed when the pollen count is high
  • avoid areas with a lot of grass, flowers, or trees

Pollen counts are greatest in the mid-morning and early-evening hours.

If you have an allergic reaction to home dust mites, you should:

  • choose anti-allergenic matresses and bedding
  • vacuum often, and dust with a clean, damp cloth
  • avoid soft furnishings, such as carpets and drapes
  • use a vacuum cleaner with a HEPA filter

What you need to know about blepharitis

Published

on

Blepharitis is a condition that affects the upper and lower eyelids. Around the eyelashes, it can cause clumping and stickiness.

Inflammation near the base of the eyelashes causes it. There are a variety of therapies available, including home remedies, that can help to alleviate symptoms.

We’ll go over what causes blepharitis, how to remedy it, and how to avoid it in this post.

Blepharitis can affect people of all ages and can be acute or chronic in nature; chronic adult blepharitis is the most frequent kind. Blepharitis is a term that refers to a persistent inflammation of the eyelids.

Pictures

The symptoms of blepharitis are depicted in the images below.

  • Blepharitis
  • Blepharitis
  • Blepharitis
  • Blepharitis affects the eyes.
  • Blepharitis
  • Blepharitis

Causes

Blepharitis can be caused by a variety of causes.

They are as follows:

  • parasites: Demodex eyelash mites
  • infection with the herpes simplex virus (HSV)
  • an inflammatory reaction to bacteria that normally live on eyelids
  • seborrhoeic dermatitis or rosacea

Blepharitis is more common in people who have dandruff. Controlling the dandruff might assist to ease the symptoms.

Dysfunction of the Meibomian glands on the rim of the eyelids is another probable reason. These glands secrete an oily material that keeps the tear film from evaporating in the eye.

Some clinicians feel that blepharitis is a prelude to Meibomian gland malfunction rather than blepharitis being caused by gland dysfunction.

Symptoms

Blepharitis can be anterior or posterior.

Anterior: This affects the eyelid’s front edge, where the eyelashes contact it.

Posterior: This affects the inner edge of the eyelid, where it meets the eyeball.

The following are the key signs and symptoms:

  • burning or stinging eyes.
  • oversensitivity to light (photophobia).
  • gritty feeling in eyes and the sensation of having something in the eye.
  • itchy eyelids.
  • red eyes.
  • irritated and watery eyes.
  • flaking and crusting at the base of the eyelashes, similar to dandruff.

Symptoms are usually more noticeable in the mornings.

Although blepharitis is not a sight-threatening condition, it can cause temporary vision loss.

Chronic blepharitis symptoms come and go, with periods of remission (a break in the symptoms) followed by exacerbations (a flare-up). It frequently affects both eyes at the same time.

Blepharitis is frequently associated with other disorders such as ocular rosacea, psoriasis, and seborrheic dermatitis.

Treatment

dry eye gel drops
Artificial tears may aid in the relief of symptoms.

Blepharitis is usually treated with a combination of medical and home remedies.

A doctor will likely prescribe home therapy, such as the ones listed below, but they can also do the following process:

Electrochemical lid margin debridement (BlephEx): This clears the eyelids of any mites, bacteria, and the biofilm that they produce. Any congested Meibomian glands are also opened.

Thermal pulsation treatment (Lipiflow): This dissolves any clogging debris in the Meibomian glands.

Intense pulse light therapy (IPL): This helps to unclog congested eyelid glands.

Severe instances of blepharitis may necessitate the use of antibiotics, either topical or oral.

Home remedies

In order to treat both forms of blepharitis, it’s important to keep your eyelids clean. Even if your symptoms have improved, you should keep doing it.

The most important aspect of therapy is self-care. Blepharitis symptoms might reappear if self-care is not maintained.

Although blepharitis cannot be cured, it can be effectively managed with medication.

People with eyelid inflammation should avoid wearing cosmetics around their eyes, such as eyeliner, mascara, and other eye makeup, in addition to home therapy.

Blepharitis treatment entails:

  • massage, to express the small oil glands of the eyelids
  • lid cleansing, to remove crusts
  • warm compresses, to loosen crusts

What is the best way to apply a warm compress?

Placing a warm compress over closed eyelids, warming the compress with warm water when it cools, and reapplying for up to 10 minutes is all it takes to use a warm compress.

The following are some suggestions:

  • Using a soft cloth only: Scrubbing too vigorously or using a rough cloth can damage the skin and eyes.
  • Dipping the cloth in warm water: Some patients have suffered facial burns by using a microwave to heat up the wet cloth.

Cleanse the eyelids after using a warm compress for up to 10 minutes.

Warming eye masks: These may have the same effect as warm cloth compresses while being more convenient. There are additional eyelid cleansers (Ocusoft, Thera Tears Sterilid) that can be used instead of dilute baby shampoo.

How do you clean your eyelids?

To do so, use a cotton swab soaked in a mild solution of baby shampoo to gently rub the eyelid margin—at the base of the eyelashes and where the glands are located. In roughly half a cup of warm water, drop 2 to 3 drops.

This lid hygiene must be done twice a day, every day as a self-care routine. This is a significant lifelong commitment, but without it, the symptoms will return.

How do you massage your eyes?

Massaging helps express the oily contents of the glands after applying the heated compress to release the sebum.

Massage the eyelid margin, where the eyelashes and glands are, with a finger or a cotton-tipped applicator or swab in tiny circular strokes.

Artificial tears

These non-prescription eye drops will assist to alleviate the dryness of the eyes caused by blepharitis during the day. Artificial tears that are free of preservatives are the finest to use.

Artificial tears may be purchased over the counter, but you should first consult your doctor to ensure that they are appropriate.

Diagnosis

Symptoms will be discussed, a medical history will be taken, and the patient’s eyelids and eyes will be examined.

Slit-lamp examination

The doctor will search for indicators that will help them figure out which sort of blepharitis you have. A slit lamp may be used.

This is a low-power microscope with an intense thin-beam light source that has been particularly constructed.

The doctor may examine the exterior of the eyes and the eyelids with the lamp while the patient’s head is held still by the chin and forehead resting on supports.

The doctor will next provide a therapy recommendation. This may or may not be the case, depending on the cause. A acceptable alternative will be picked if blepharitis looks to be caused by a skin condition, such as rosacea, or if it is caused by mites.

Complications such as Meibomian cysts, conjunctivitis, and corneal injury can all be avoided with treatment.

A novel laser treatment for macular degeneration may be effective

Published

on

A novel form of laser treatment has the potential to reduce the course of age-related macular degeneration (AMD), a leading cause of visual loss, without causing retinal damage.

A retinal artery occlusion, or eye stroke
A novel form of laser therapy that does not harm the retina has been found to minimize the visual loss associated with age-related macular degeneration.

This was the finding of a research published in The FASEB Journal by the University of Melbourne in Australia.

The effectiveness of a new low-impact, low-energy laser therapy for individuals with early age-related macular degeneration (AMD) was investigated by Erica Fletcher, an associate professor at Melbourne’s Department of Anatomy and Neuroscience, and colleagues.

They discovered that, unlike previous laser therapies, the “nanosecond laser” they examined did not harm the retina, which is the light-detecting tissue at the back of the eye.

Prof. Fletcher claims that theirs is the first study to show how the novel laser treatment can help people with AMD improve their eye health.

AMD is a painless eye condition that causes central vision loss over time. It is the main cause of irreversible impairment of fine or close-up vision – such as that required for reading – among people aged 65 and older, according to the Centers for Disease Control and Prevention (CDC) (resource no longer accessible at www.cdc.gov).

According to estimates, roughly 1.8 million Americans aged 40 and over have AMD, with another 7.3 million at risk.

AMD is responsible for 48 percent of severe vision loss in Australia, where the study took conducted, with an estimated 17,700 new cases per year.

New laser treatment reduced drusen and thickness of Bruch’s membrane

In the early stages of AMD, examination of the back of the eye reveals the development of microscopic fatty deposits known as drusen, as well as a thickening of a thin layer of tissue known as Bruch’s membrane. As these symptoms increase, the core section of the retina is slowly destroyed.

According to the findings, the nanosecond laser can diminish drusen and thin the Bruch’s membrane without causing damage to the retina’s structure.

The researchers conducted a number of tests and experiments as part of the study. One study included 50 AMD patients who had a single session of nanosecond laser therapy and were followed up on two years later. Their drusen burden was lowered in comparison to a similar group of untreated individuals, according to eye tests.

The membrane was thinner three months after treatment in mice with thicker Bruch’s membrane who underwent the laser therapy.

New laser treatment did not damage the retina

The researchers used human and animal eyes to assess the new laser’s effect on the retina, for example, using a procedure called “immunohistochemistry,” which can detect minute changes in tissue structure.

The researchers state this about their research:

“Nanosecond laser resolved drusen independent of retinal damage and improved BM [Bruch’s membrane] structure, suggesting this treatment has the potential to reduce AMD progression.”

The findings “indicate that treating people with AMD with our new nanosecond laser lowers indications of the disease,” according to Prof. Fletcher.

“Most importantly,” she continues, “the nanosecond laser does not cause harm to the delicate retina, unlike other lasers now used to treat eye disease.”

The researchers also discovered evidence that using the nanosecond laser to treat one eye can have beneficial benefits on the other eye, raising the prospect that one therapy could be enough to correct disease in both eyes.

Glaucoma, in which fluid builds up in the eye and puts pressure on the optic nerve, is another main cause of blindness. The condition is treatable, but there is no treatment at this time.
