Corneal Ulcer is an open sore or epithelial defect on the cornea. Corneal ulcers may be caused due to trauma, wearing contact lenses, or corneal drying. If left, untreated corneal ulcers may lead to blindness. Symptoms are:
• Redness of eyelid
• Pain or discomfort
• Swollen eyelids
• Tearing or pus or thick discharge
• Blurry vision
• Sensitivity to light
HOW IS CORNEAL ULCER DIAGNOSED?
The diagnosis of the condition is usually carried out by the Ophthalmologist who will conduct a regular eye test as well as a Fluorescein eye stain test which involves the use of orange dye on blotting paper through which the doctor will examine the eye by flashing a slit lamp. The presence of the ulcer will lead to a green appearance.
HOW IS CORNEAL ULCER TREATED?
Treatment for corneal ulcers and infections depends on the cause and it should be done as soon as possible. Antibiotic drops are used that work against many kinds of bacteria. Severe ulcers sometimes require a corneal transplant. Corticosteroid eye drops may be used to reduce swelling and inflammation in certain conditions.
DID YOU KNOW?
If the ulcer takes place in the central part of the cornea, the treatment would take much longer. There is a chance that in such cases, you may have permanent damage to your vision too.
