Cornea Diseases

What Is the Cornea?

The cornea is the clear, dome-shaped surface that makes up the outermost layer of the eye. This front part of the eye contains an extremely organized grouping of proteins, cells and nerves through multiple layers of corneal tissue. For a person to see well, there must be functionality between the various layers of the cornea. In addition to supporting your vision by acting as the outermost lens for the eye, the cornea is also protective, screening UV rays before light travels through the eye.

What Are Some Common Conditions That Affect the Cornea?

The cornea may be affected by the infection, allergies, eye disease, and dystrophies. There are dozens of conditions that may develop in or affect the cornea. These include:

  • Dry eye syndrome, in which the tear film is compromised.
  • A corneal infection, such as keratitis.
  • Ocular herpes, a viral infection caused by the herpes simplex virus.
  • Ocular shingles, a viral infection caused by the varicella-zoster virus, the same virus that causes chickenpox.
  • Pterygium, fleshy growth on the cornea that may occur due to UV exposure.
  • Iridocorneal endothelial syndrome (ICE) involves swelling of the cornea and the development of glaucoma.
  • Limbal Stem Cell Deficiency involves the limited regeneration of corneal cells and subsequent thinning of this important structure.

Common corneal dystrophies include:

  • Keratoconus is the most common corneal dystrophy. This condition is characterized by a misshapen cornea and subsequent refractive error.
  • Fuchs’ dystrophy, a condition in which cells in the endothelium deteriorate, eventually causing the cornea to swell.
  • Granular dystrophy involves the growth of lesions inside the eye.
  • Lattice dystrophy includes the abnormal growth of protein fibers within the stroma of the iris or cornea.
  • Map-dot-fingerprint dystrophy occurs when the epithelium develops in an abnormal manner, inhibiting epithelial cells from adhering to it.

What Are the Symptoms of Corneal Diseases?

The symptoms of the corneal disease may be unique to the condition itself. The common symptoms of dry eye disease include a scratchy, foreign-body sensation that coincides with excessive tearing or burning. Pterygium is characterized by noticeable fleshy growth. Injury or infection in the cornea may be indicated by light sensitivity and pain. Anytime ocular symptoms linger or recur, the eyes should be examined by a qualified ophthalmologist.

Who Is at a Greater Risk of Developing a Cornea Disease?

Individuals with a family history of cornea disease may have an increased risk of inherited conditions. Research is currently exploring the genetic factors that may be involved in this risk. Other corneal conditions also have specific risk factors, such as having had the chicken pox virus (Ocular shingles) or exposure to herpes (Ocular herpes). People who wear contact lenses may have an increased risk for corneal injury or conditions related to infection, such as keratitis.

How Can Cornea Consultants of Albany Diagnose Corneal Disease?

Corneal disease can be diagnosed in our office during a thorough, dilated eye exam by one of our ophthalmologists. Our ophthalmologist will use special instruments that magnify and evaluate the various structures of the eye. Technology such as corneal topography can capture characteristics of the cornea that indicate warning signs of cataracts, corneal damage, and other conditions.

What Are My Treatment Options for Cornea Diseases?

There are stages to corneal disease treatment, just like there are stages to the disease itself.

  • Basic treatments may be implemented to address mild symptoms of cornea disease, infection, or dystrophy. These include special eye drops that decrease inflammation, ointments, or antibiotics to treat the infection.
  • Contact lenses may be prescribed for certain conditions such as keratoconus or some corneal dystrophies that affect the shape of the front of the eye.
  • The corneal transplant surgery may be necessary to treat conditions such as advanced keratoconus, iridocorneal endothelial syndrome, FUCHS dystrophy and other problems.
  • Laser therapy such as phototherapeutic keratectomy (PTK) may be considered as an alternative to corneal transplant in patient’s whose eye is capable of regenerating new tissue.
  • Crosslinking is a technique that may be utilized to treat keratoconus by stabilizing corneal tissue using ultraviolet light.

How Can I Prevent Cornea Diseases?

Cornea diseases Albany NY

It is not possible to prevent inherited corneal conditions. In such instances, routine eye exams provide necessary information that enables a person to preserve vision.

Infectious corneal conditions are caused by viruses and bacteria. To minimize the risk of infection, experts recommend that we do not share makeup or eye care products such as contact lens solution, cases or eye drops (Do not wear your contact lenses overnight). Regular hand-washing throughout the day can also inhibit the transfer of bacteria or viruses from the hands to the eyes.
