This condition is most commonly caused by infections. Bacterial, viral (herpes simplex virus or varicella virus) and fungal infections may cause corneal ulcers. Injury and trauma can also bring about an ulcerated cornea. If glass particles or a sharp object strikes the cornea, the corneal surface may become scratched, damaged or cause an abrasion, creating a breeding ground for bacteria – and as a result, cause the corneal ulcer.
Certain eye disorders such as dry eyes and disorders that are due inadequate eyelid closure such as Bell’s palsy may also lead to corneal ulcers. Other factors such as chemical burns, harsh solution splashes, and wearing contacted lenses for extended periods without removing them at night will also increase your risk of developing corneal ulcers or lesions.
In addition, improper care of contact lenses and excessive use of eye drops that contain steroids can make you susceptible to corneal ulcers and damage the cornea. If left untreated, serious eye complications such as corneal scarring and intraocular infection may develop. |
