Cornea and External Diseases — Conditions We Treat

The following conditions are some of the most common conditions treated by specialists in this area. These specialists offer expert care for many other related medical problems. If you need care for a condition not listed here, please call (888) 352-RUSH (7874) to find a doctor who can help you.

  • Astigmatism

    Astigmatism is a common vision condition that causes blurred vision. Astigmatism is known as a refractive error because it affects how the eye bends or “refracts” light. It frequently occurs with nearsightedness (myopia) or farsightedness (hyperopia).
  • Cataracts

    Cataracts occur when a normally clear lens in the eye becomes cloudy. Cataracts can lead to blindness. However, with treatment, any visual impairment is often reversible. Cataracts symptoms include cloudy or blurry vision, excessive glare, double vision, weak night vision and frequent eyeglass prescription changes.
  • Conjunctivitis, also known as pink eye, is a common eye infection, especially in children. It affects the tissue inside the eyelid and on the white part of the eye. Conjunctivitis usually does not affect vision.
  • Corneal Degenerations

    Corneal degenerations are changes in the structure or function of the cornea that occur over time. The result is blurred vision, irritation and redness. Chronic exposure to sunlight causes two common degenerations, pinguecula and pterygium.
  • Corneal Dystrophies

    Corneal dystrophies are rare, inherited and usually progressive eye disorders. They affect both eyes. Corneal dystrophies alter the cornea, which is the clear, dome-shaped surface of the eye. Any of the five layers of the cornea can be involved. The result may be decreased vision, discomfort or corneal scarring.
  • Corneal Ulcers

    Corneal ulcers can be bacterial, viral or fungal. Infections of the cornea need prompt, expert evaluation and treatment. Corneal ulcers usually follow an injury to the cornea. They cause pain, redness and light sensitivity. Soft contact lenses may also cause corneal ulcers if the lenses are not cleaned properly, or if lenses are worn overnight.
  • Dry Eye

    Dry eye is a condition in which the body does not produce enough tears or when the tears do not have all the correct elements. Dry eye symptoms include having the sensation that something is in the eye, excessive watering of the eyes and a decrease in visual clearness.
  • Hyperopia

    Hyperopia, or farsightedness, is a condition in which objects in the distance appear clear, while objects close-up appear blurry. When a person with hyperopia reaches his or her late 30s or early 40s, the near vision typically gets worse, and patients with hyperopia often need reading glasses.
  • Myopia

    Myopia is nearsightedness, or difficulty seeing things in the distance. People with myopia can use glasses or contact lenses to correct their vision. Another option is laser eye surgery.
  • Presbyopia

    Presbyopia is sometimes called the aging eye disorder. It is the inability to focus on things at arm’s length or closer. It usually develops in people who are older than 40.
