Disorders of the Conjunctiva

pterygiumMany disorders of the conjunctiva are as a result of chronic UV exposure.

One of the most common conditions is a ptergium. This is a piece of tissue that is abnormal and grows onto the cornea, and can cause a variety of visual problems such a distorted vision and decreased vision, and ocular discomfort as they often get inflamed.

Treatment involves removal of the abnormal tissue and an auto-conjunctival graft is used to prevent the lesion growing back. 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 approximately 1 month following the procedure.
