Corneal Ulcer

Book Appointment

A corneal ulcer is an open sore that develops on the cornea, the clear, dome-shaped surface of the eye that helps focus light. Corneal ulcers are most commonly caused by infections from bacteria, viruses, fungi, or parasites. They can also result from dry eyes, trauma, or prolonged contact lens use. If left untreated, corneal ulcers can lead to severe complications, including vision loss or blindness. Early diagnosis and treatment are crucial to prevent further damage to the eye.
