Cornea and Anterior Structures Diagnoses

The Cornea and Refractive Surgery Service provides comprehensive care to patients with corneal and anterior segment disease, and provides refractive surgery for vision correction. Our specialists in the Comprehensive Ophthalmology Service are in the best position to evaluate, and often treat, common eye disorders in their early stages. If the disease progresses, however, a specialist in corneal medicine and surgery is better able to manage all aspects of the problem.

Common disorders of the cornea and anterior chamber (front of the eye) that may be evaluated initially in the Comprehensive Ophthalmology Service or in the Cornea Service:

  • Allergic conditions, which can cause redness, itching, blurry vision and swollen eyelids
  • Blepharitis, an inflammation of the eye lid
  • Cataract, a cloudiness of the normally clear lens of the eye
  • Conjunctivitis, or inflammation of the covering of the eye and inner eye lid
  • Dry eye, in which the quality or amount of tears is compromised, and the eye is unable to keep its surface well lubricated and comfortable
  • Disorders associated with refractive clarity. These disorders may be corrected with a variety of approaches including eyeglasses, contact lenses, surgery and refractive surgery. They include:
    • astigmatism, an uneven curvature of the corneas
    • hyperopia, or farsightedness
    • keratoconus, uneven curvature in the center of the cornea
    • myopia, or nearsightedness

Less common disorders of the cornea and anterior chamber may require the attention of a cornea specialist for diagnosis and care. Some of these include:

  • Cornea dystrophies, including Fuchs' endothelial, Lattice and MDF dystrophies
  • Infections (bacterial, viral and fungal), including herpes zoster (shingles), ocular herpes simplex, and others. These infections can reduce visual clarity, produce corneal discharges, and perhaps erode the cornea. Severe corneal infections can lead to corneal scarring, which can impair vision and may require a corneal transplant.
  • Inflammatory disorders with significant eye implications (episcleritis, uveitis)
  • Iridocorneal endothelial syndrome (ICE), in which disorders of the iris and the cornea occur in conjunction with glaucoma
  • Stevens-Johnson Syndrome, a skin disorder that can affect the eyes
  • Pseudophakic Bullous Keratopathy (PBK), a rare complication of cataract surgery
  • Pterygium, a type of growth on the cornea

The cornea can be damaged after a foreign object has penetrated the tissue, such as from a poke in the eye. At other times, bacteria or fungi from a contaminated contact lens can pass into the cornea. Situations like these can cause painful inflammation and corneal infections called keratitis.
