A 55 year-old man had an irritable left eye.
To exclude malignancy, a biopsy was taken form the tarsal conjunctiva.
The histological appearances are shown in Figures 1 and 2.
1. The conjunctiva shows a ‘papillary’ conjunctivitis.
2. The main causes of a papillary conjunctivitis are:
a. allergic conjunctivitis (atopic, vernal, seasonal or perennial).
b. Topical medication: drops, preservatives and ointments.
c. Chronic irritation: giant papillary conjunctivitis, SLK, dry eyes etc.
In this case, the patient had floppy eyelid syndrome.
