Chico Eye Center has the only corneal specialist between Redding and Sacramento.
The cornea is a thin, clear, spherical layer of tissue on the surface of the eye that provides a window for light to pass through. In a healthy eye, the cornea bends or refracts light rays to help them focus precisely on the retina in the back of the eye.There are many diseases that can affect the cornea, causing pain or loss of vision. Disease, infection or injury can cause the cornea to swell (called “edema”) or degrade (become cloudy and reduce vision).Treatment for corneal disease can take many forms, depending on the underlying problem as well as the patient’s preferences. Some conditions may resolve on their own and many can be treated with medication. In other cases, a corneal surgery may be necessary in order to prevent blindness or restore a severely damaged eye.
- Keratoconus – a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. In patients with keratoconus, the cone-shaped cornea deflects light and causes distorted vision.
- Fuch’s dystrophy – an inherited eye disease that causes the cells in the innermost layer of the cornea to deteriorate, leading to distorted vision and corneal swelling. As these cells continue to deteriorate, fluid will continue to build up and vision will worsen. Once these cells are lost, they do not grow back.
- Pterygium – a benign growth of the conjunctiva (the lining of the white part of the eye) that grows on to the cornea and partially covers the iris (colored part of the eye). Patients with a pterygium often first notice the condition because of the appearance of a lesion on their eye or because of dryness, itchiness, irritation, tearing, and/or redness.
