Corneal diseases refer to conditions that affect the cornea of the eye. The cornea is the transparent outer layer covering the front of the eye and serves both a protective and focusing function. A normal cornea is transparent, allowing light to enter the eye and helping to focus it onto the retina, enabling clear vision of objects.
Corneal diseases may be caused by various factors, including infections, injuries, genetic factors, autoimmune diseases, malnutrition, or complications following eye surgeries. Common corneal disorders include:
1. Keratitis: Corneal infection caused by bacteria, viruses, fungi, or parasites.
2. Dry eye syndrome: Caused by insufficient tear production or excessive tear evaporation, leading to dry eyes and potentially damaging the corneal surface.
3. Corneal ulcer: A severe injury to the corneal surface that may lead to vision loss.
4. Corneal foreign body: Small particles or fragments entering the eye that may scratch the cornea.
Typical symptoms include photophobia, tearing, pain, eyelid spasm, and other signs of irritation, as well as corneal opacity. Treatment depends on the specific cause and may include medication, corneal transplantation, and other supportive therapies.
