An interventional study of Sham and Argon Laser Treatment in Pterygium, sponsored by Instituto de Oftalmología Fundación Conde de Valenciana. Completed at 1 site in Mexico. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2018-04-02.

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

Exclusion Criteria:
Slit lamp light exposure
Other: Sham
Argon Laser Treatment
Procedure: Argon Laser Treatment
This group will not receive argon laser medical treatment; instead, they will be only exposed to the slit lamp light.
This group will receive argon laser medical treatment to the body and head of pterygium
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.
