Disorders of the

Many disorders of the conjunctiva are as a result of chronic exposure to ultraviolet light (UV).

One of the most common conditions is pterygium. This is when abnormal cells grow from the conjunctiva onto the cornea, and can cause a variety of problems such a distorted vision, decreased vision and discomfort as a pterygium often becomes inflamed.

Treatment is surgical removal of the abnormal tissue and an auto-conjunctival graft is used to prevent regrowth. The graft is taken from another part of the patient’s conjunctiva, usually from under the top eyelid. Patients need to use anti-inflammatory and antibiotic eye drops for 1-2 months following the procedure.
