What are the causes and risk factors of corneal disease?
The causes of corneal disease vary widely. The conditions listed above are due to hereditary (inherited) causes, infection, trauma, autoimmune disorders, nutritional deficiencies, allergy, secondary causes (other eye diseases that also affect the cornea), growths, and tumors among others.
Risk factors similarly vary depending on the individual's circumstances. Some risk factors are not modifiable, such as inherited genetic conditions. Others might be avoidable by limiting exposure to trauma and infection. In many people, prompt treatment of a corneal disease in its early stages will minimize the severity of the disease and its complications.
What are the signs and symptoms of corneal disease?
Signs of corneal problems can include redness around the cornea and/or corneal cloudiness. Symptoms include
- visual impairment, such as blurred or cloudy vision,
- severe pain in the eye,
- tearing, and
- sensitivity to light.
- Some patients have additional symptoms of headache, nausea, and fatigue.
Blurred vision may be the result of an irregular tear layer or epithelial layer (as seen in dry eye), scarring (following trauma or infection), cataracts, deformity of the corneal curvature (as seen in keratoconus), or swelling of the cornea (as seen in Fuchs' dystrophy). Pain and light sensitivity can be quite severe, especially in conditions affecting the outermost layer (epithelium) of the cornea. Examples include traumatic abrasions, infectious ulcers, and erosions from dryness.
