Corneal Disease: Explanation, Symptoms, and Treatment

October 10, 2017 by Anne Arundel Eye Center

Your cornea – the clear, protective outer layer of the eye – not only protects your eye from dirt and germs, but also plays a key role in your vision. As light enters the eye, it is focused or refracted by the shape of the cornea. If your cornea sustains damage through disease, infection or injury, the resulting scar tissue can interfere with your vision by blocking or distorting light as it enters your eye.

There are several different conditions including infections, degenerations and other disorders that affect the cornea. These include:

Astigmatism: Caused by an irregularly shaped cornea, astigmatism is a refractive error in which the eye has trouble focusing light. Astigmatism is the most common form of corneal problem. Treatment typically involves the use of glasses or contacts.

 Corneal Abrasion: Caused by trauma to the eye, a corneal abrasion refers to a scratch on the outer layer of the eye. It is the second most common form of corneal distress. Treatment traditionally involves patching of the eye, though newer bandage contact lenses are beginning to see more use. These allow people to stay functional during the healing process.

Keratits: This form of corneal disease is an inflammation of the cornea that occurs with viral, bacteria or fungal infection. Symptoms of keratitis include severe eye pain, reduced visual clarity, and discharge.

Ocular Herpes (Herpes of the Eye): Similar to cold sores on the lip, this reoccurring viral infection produces sores on the surface of the cornea that, in time, can spread deeper into the cornea and eye. There is no cure for ocular herpes, but it can often be controlled with the use of antiviral drugs. You can also try using Valtrex. Valtrex (Valacyclovir) is an antiviral medication used to treat infections caused by certain viruses. It helps the body fight infection by slowing the growth and spread of the herpes virus. It is used to treat shingles (caused by herpes zoster), genital herpes, and cold sores around the mouth. Valtrex is also a treatment for cold sores in children over the age of 12 years old and as a chickenpox medication in children who are over the age of 2 years.

Herpes Zoster (Shingles): This is actually a recurrence of the chickenpox virus, since most of us have already had the disease. Symptoms of Herpes Zoster include blisters or lesions on the cornea, fever, and pain from inflamed nerve fibers.

Corneal Dystrophies

There are over 20 of these diseases that cause structural problems with the cornea. The most common forms include:

Keratoconus: This is a progressive disease in which the cornea thins and even changes shape, creating either mild or severe distortion (astigmatism) and nearsightedness (myopia).

Map-Dot-Fingerprint Dystrophy: As the basement membrane of the epithelium of the cornea grows irregularly, abnormalities resembling maps, dots and fingerprints form in the cornea. While this form of corneal disease is mostly painless and causes no vision loss, epithelial erosion may occur, exposing the nerves lining the cornea and causing severe eye pain.

Fuchs’ Dystrophy: Seemingly happening for no apparent reason – although you may have a genetic predisposition to the disease – Fuch’s Dystrophy involves the gradual deterioration of endothelial cells. As these cells thin, they can no longer remove water from the corneal stroma. This causes the stroma to swell and distort vision.

Lattice Dystrophy: This disease is characterized by the presence of abnormal protein fibers throughout the stroma. This can result in the clouding of the cornea and reduced vision and in rare cases, epithelial erosion.

Symptoms of Corneal Disease

 The cornea has the ability to quickly repair itself after most injuries or diseases. However, more serious situations may result in a much more prolonged healing process. If this is the case, the following symptoms should serve as an immediate indicator of a deeper medical issue:

  • Eye pain
  • Blurred/blurry vision
  • Tearing
  • Redness
  • Extreme sensitivity to light
  • Corneal scarring

If you feel you may be experiencing any of these symptoms, schedule an appointment with your eye doctor immediately. Any sudden change in your vision is a serious medical condition that requires prompt medical attention from your optometrist or ophthalmologist.

Although corneal disease resulting from hereditary factors cannot be prevented, infectious corneal disease caused from bacteria and viruses can be avoided. You should never share eye makeup, contact solution, lens cases, and eye drops with anyone as this may increase the risk of infection.

However, if you do contract some form of corneal disease, vision can be preserved through early detection and treatment. This is just another reason why regular eye exams are so important.

Glaucoma: An Overview from Dr. Nathan Frank

January 30, 2012 by Anne Arundel Eye Center

According to a survey conducted in 2002 by Prevent Blindness America, 30 percent of Americans have never heard of
glaucoma and only half of those participating in the survey actually knew what it was. Glaucoma is the second leading cause of blindness in the world, and specialists believe that roughly 2.2 million people in America are affected. Only half of these individuals know that they have the disease. Given that January is Glaucoma Awareness Month, this is a great time to review the condition so that you, as patients, can become better informed and more knowledgeable.

Glaucoma is a multi-factorial disease that causes damage to the optic nerve that eventually leads to vision loss. Peripheral (side) vision loss occurs due to damage of the optic nerve of eye, which is similar to a fiber optics cable with about 1.2 million fibers that send images from the eye to the brain. There are two main types of glaucoma: primary open angle glaucoma and angle closure glaucoma. Both are usually marked by increased eye pressure inside the eye, but differ in the anatomical structure of the drainage system of the eye.

Risk factors for glaucoma? Everyone is at risk for glaucoma, newborn babies and senior citizens alike. However, there are several groups of people with an increased risk of developing the disease. Risk is heightened by:

  • Race (African Americans, Asians and Hispanics)
  • Diabetes
  • High blood pressure
  • Steroid Use
  • Age (People over 60)
  • History of eye trauma
  • Family History of glaucoma
  • High near-sighted patients

What are the common symptoms of glaucoma? The majority of people that have glaucoma are without symptoms. The visual symptoms that do occur tend to occur later in the disease process.

How to diagnose glaucoma? A comprehensive eye evaluation is imperative to rule out any suspicion for glaucoma. There are several important factors that need to be assessed prior to making a diagnosis. These include: measurement of eye pressure (normal range 12-22), a close assessment of the optic nerve, a peripheral visual field measurement, an exam of the drainage system of the eye, and finally a measurement of the cornea of the eye. These measurements are repeated once or twice a year or more often if there is any concern about progression.

How is glaucoma treated? The best way to protect your vision if diagnosed with glaucoma is to continue care
with your eye care provider. The goal of treatment is to lower the intraocular pressure to prevent further damage to the optic nerve. When diagnosed with glaucoma, the first line of treatment usually starts with the use of a single eye drop that is instilled once a night. If further pressure lowering is needed, additional drops can be used. Further treatment options include laser therapy or, if necessary, surgical treatment.

Glaucoma is a very complicated disease and this is only a brief overview. Some questions may still remain; a great
resource for information is glaucoma.org, a website that is constantly updated with information for those with glaucoma and for those who may know others with glaucoma.

Diabetic Retinopathy: Signs and Symptoms, Treatment, and Prevention

December 30, 2011 by Anne Arundel Eye Center

Currently, between 40-45% of Americans with diabetes have some varying degree of Diabetic Retinopathy, the most common diabetic eye disease and the leading cause of blindness in American adults.  Specifically, Diabetic Retinopathy is damage to the blood vessels in the eye.

Types (Stages) of Diabetic Retinopathy

Non-proliferative: This is the first stage of Diabetic Retinopathy. It involves the enlargement of blood vessels with fluid/blood leaking into the retina, causing problems with one’s vision.

Proliferative: This is the more advanced type of Diabetic Retinopathy. It involves the forming of new blood vessels in the eye. These blood vessels then hemorrhage, causing scarring on the retina and other parts of the eye. This can result in several problems, including complete vision loss.

Signs and Symptoms of Diabetic Retinopathy

•           Blurred vision/ blurry vision

•           Shadows or loss of areas of vision

•           Difficulty seeing at nighttime

 

By the time these symptoms appear, it may be too late to reverse the damage. This is why it is important for all those with diabetes to have professional eye exams (at least once a year) in addition to regular medical care and checkups with their primary care physicians.

Treatment of Diabetic Retinopathy

The best form of treatment for diabetic retinopathy is prevention. However, there are still some very effective ways to treat diabetic eye diseases, including:

•           Focal Laser Treatment: Also known as photocoagulation, this laser treatment can slow or even stop blood and fluid from leaking in the eye.

•           Scatter Laser Treatment: Also known as panretinal photocoagulation, this laser treatment is used to shrink any abnormal blood vessels in the eye.

•           Vitrectomy: This surgical treatment is used to remove blood from the middle of the eye (vitreous) as well as any scar tissue that may be pulling on the retina.

While new treatment options are in development as scientists work toward a better understanding of this disease, regular eye exams and early detection remain your best options for fighting Diabetic Retinopathy.

Glaucoma: Finding Out If You Are At Risk

July 22, 2011 by Anne Arundel Eye Center

You may have heard of glaucoma which is a common eye disorder and one of the leading causes of blindness in the United States. But what else do you really know about it and are you at risk?
Glaucoma is an eye disease in which the optic nerve suffers damage and can permanently impair vision in the eye(s). There are different types of glaucoma and the disease can present itself without warning or symptoms. The most common form is the result of elevated pressure of the fluid in the eye and sometimes other factors that cause the fibers running through the optic nerve to slowly deteriorate. Without treatment, glaucoma can lead to permanent vision loss.

Who is at risk?

Everyone is at risk. However, certain factors can increase that risk, including: if you are over 60 years of age, if you are African American, if you have high myopia (nearsightedness), diabetes, hypertension, or if you are a steroid user.

Over 3 million Americans have glaucoma, yet half are unaware that they even have the disease. This is why regular eye exams are so important. While there is no cure for glaucoma, these eye exams, early detection, and treatment (medication and possibly surgery) can help slow or even prevent further vision loss brought on by this disease.

So, when was the last time you had a thorough eye exam?

What You Should Know About Diabetic Retinopathy

July 15, 2011 by Anne Arundel Eye Center

Diabetes affects more than 23.6 million people in the United States alone – meaning that 7.8% of the population has the disease. Of these individuals, between 40 to 45 percent have some degree of Diabetic Retinopathy, the most common progressive eye disease resulting from long-term diabetes. Diabetic Retinopathy, which damages to the blood vessels in the eye, is also the leading cause of blindness in American adults.

It is extremely important for those with diabetes to not only seek regular medical care, but also regular eye exams (at least once a year), as well. If caught early enough, Diabetic Retinopathy is very treatable. However, if you wait until you experience symptoms of the disease, it may be too late to reverse the damage, though worsening of Diabetic Retinopathy may be slowed with treatment even in advanced stages of the disease.

Symptoms may include: 

  • Blurred vision
  • Shadows or loss of areas of vision
  • Difficulty seeing at nighttime

In the early stages of Diabetic Retinopathy, no symptoms occur, making the disease almost impossible to diagnose without the help of a professional. This is why regular eye exams are so important.

There are two types (stages) of the disease:

Non-proliferative (the first stage): Enlarged blood vessels and fluid/blood leaking into the retina cause problems with eyesight.

Proliferative (advanced):  New blood vessels form in the eye and hemorrhage, causing scarring on the retina and other parts of the eye.  This results in many problems with sight and can lead to complete vision loss.

While new treatment options are in development as scientists work toward a better understanding of this disease, regular eye exams and early detection remain your best options for fighting Diabetic Retinopathy.
