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.

FDA Approves a New Lens for Cataract Patients

September 16, 2016 by Anne Arundel Eye Center

FDA Approves New Lens for Cataract PatientsCataracts affect nearly 22 million Americans age 40 and older, according to the American Academy of Ophthalmology. And, as you may recall from previous blogs, cataract surgery is a painless outpatient procedure that involves removing the clouded lens and, in most cases, replacing it with a clear, intraocular lens implant (IOL). Your eye doctor will make a small incision on the side of your cornea and use ultrasound vibrations to break the natural lens into small pieces. These fragments are removed and replaced with an IOL.

Are You at Risk of Cataracts?

November 18, 2015 by Anne Arundel Eye Center

Often times, we don’t give our eye health as much thought as we should. Those who don’t have the need for vision correct, or have any other eye issues, may not even go in for an annual exam. However, failing to keep up on eye health can lead to troublesome eye issues resulting from undiagnosed issues in the lens, like cataracts. Luckily, many cataracts are visible before they cause any changes in vision, and are easily removed with a simple surgery.

The Elderly are at an Increased Risk for Eye Disease

October 28, 2011 by Anne Arundel Eye Center

 In a statement by National Eye Institute Director Paul A. Sieving, M.D., Ph.D., on World Sight Day 2011, the Director urged older Americans to protect their vision. Because, as Sieving explained, older people are simply at an increased risk for eye diseases, including age-related macular degeneration (AMD), Cataracts, Glaucoma, and Diabetic Retinopathy. 

AMD – This eye disease can cause loss of central vision due to the breakdown of the light-sensing cells in the retina.

Cataracts – This eye disease clouds vision because of a clumping of proteins in the eye’s lens.

Glaucoma – This eye disease involves damage to the optic nerve caused by increased intraocular pressure (IOP).

Diabetic Retinopathy – This eye disease impairs vision due to diabetes-related injury to the eye’s blood vessels.

Early stages of these diseases have no symptoms, which is why regular eye exams are crucial to catching eye disease before permanent vision loss occurs. The importance of early detection and treatment of age-related eye disease cannot be overstated.

If you experience a sudden change in vision, such as blurriness/blurry vision, schedule an appointment with your eye doctor immediately. If this change in vision is extreme or if any eye pain is involved, consider having a family member or friend drive you to the emergency room.

Any change in your sight is a serious medical condition that requires immediate attention.

Insomnia and the Yellowing of the Eye’s Lens

October 21, 2011 by Anne Arundel Eye Center

A recent study uncovered a direct link between the yellowing of the eye’s lens and insomnia. The study evaluated participants (970 in total) using a lens autofluorometry, a non-invasive method that determined how much blue light was transmitted to the retina. And because blue light plays a crucial role in regulating the brain’s melatonin levels – which directly affects one’s daily sleep-wake cycle – subjects with lower levels of blue light were more prone to sleep disturbances.

Volunteers were considered to have a sleep disorder if they confirmed that they “often suffer from insomnia” or if they purchased prescription sleeping pills within the last 12 months.

But what was causing these individuals to filter out blue light?

As the lens of the eye becomes more yellowed it filters out more and more blue light. This yellowing occurs naturally as we age and may explain why sleep disorders become more frequent with increasing age. It also may explain why smokers and individuals suffering from diabetes mellitus also experienced higher rates of sleep disorders. Diabetes and smoking have been linked to the pre-mature yellowing of the eye’s lens,

Currently, the only known way to effectively reverse the yellowing process and thus possibly to improve sleep is through cataract surgery.
