Pterygium Clinical Trial

Official title: Manifestations of Ocular Irritation Following Pterygium Excision With Sutures Fixed Conjunctival Autograft

Status Completed

Clinical Trial Summary

In this work, the manifestations of ocular irritation associated with vicryl 8/0 sutures fixed conjunctival auto-graft in pterygium patients were evaluated. The severity of post-operative foreign body sensation, pain, and watering was subjectively evaluated. The localized nasal quadrant conjunctival hyperemia was also evaluated. It was found that sutures fixed conjunctival auto-graft can be used safely with short-term minimal to moderate tolerable manifestations of ocular irritation with no significant complications.

Clinical Trial Description

All the patients were subjected to pterygium excision surgery with conjunctival auto-graft under local anesthesia. The graft was fixed by vicryl 8-0 sutures.Ocular irritation symptoms including pain, foreign body sensation and watering were subjectively evaluated. Pain was evaluated using 5 points scale, where (0) indicated no pain; (1) very mild easily tolerable pain; (2) mild pain with discomfort; (3) moderate pain that interfered with the usual activities; (4) severe pain that totally interfered with performing daily activities or sleep. Foreign body sensation and watering of the eye were evaluated with the use of a 4 points abnormal sensation scale, where (0) indicated no abnormal sensation; (1) is somewhat bothersome; (2) is moderately bothersome; (3) is very bothersome. The score of patients' subjective symptoms evaluation were collected in a total score which ranged from zero to a maximum of 10. A total score of 3 or less was considered as minimal irritation (grade I), 4-6 was considered as mild-moderate tolerable irritation (grade II), and 7 or more was considered as severe annoying irritation (grade III).

The degree of localized conjunctival hyperemia involving the nasal quadrant was evaluated 2 weeks, 1,2 and 3 months post-operative using the Cornea and Contact Lens Research Unit (CCLRU) photographic grading scale. In this scale 1 refers to very slight; 2 slight; 3 moderate; 4 severe. Decimal fraction of 0.5 was added to describe the intermediate cases. ;
