Treatment of Primary Type I Pterygia With Argon Laser

Instituto de Oftalmología Fundación Conde de Valenciana16 enrolled

Overview

Introduction: Pterygium is a wing shape degenerative and hyperplastic growth of the bulbar conjunctiva extending onto the cornea, most commonly on the nasal side. Management of pterygium can be medical, surgical or combined. Alternative treatments as photocoagulation of blood vessels of the pterygium, have been described, especially in recurrent pterygia. Objectives: To determine whether Argon laser treatment reduces the symptoms and pterygium size in primary type I pterygia patients when compared with medical treatment. Subjects and Methods: Prospective, comparative and interventional study. Patients with type I pterygia in both eyes were included. The eyes were randomly divided to receive either Argon laser treatment or only topical medical treatment

Outcomes

Primary Outcomes

Pterygia measurements

Measurements were performed according to Welch et al. modified technique as following: the distance in millimeters from the limbus to the apex of the lesion on the cornea (horizontal length) was performed using the slit-lamp beam (BQ 900, Haag-Streit, Koeniz, Switzerland). A standard magnification of 16 was used and the variable aperture was focused from the limbus to the apex.
