A 55 year old male, welder by occupation came to the ophthalmology OPD with disturbance in vision since a month which was gradual in onset and also presence of a membrane over iris area since a few months, which then led to diminished vision in the right eye.
On ocular examination-
A triangular fold of conjunctiva was seen encroaching the cornea in the area on palpebral aperture on the nasal side. It was also encroaching upon the papillary membrane, causing the visual disturbances.
A diagnosis of Pterygium was made.
The condition was treated with Surgical excision; free conjunctival membrane graph was used to cover the bare sclera to reduce recurrence.
