Purpose: To evaluate the safety and 1-year effect of pattern scanning laser photocoagulation treatment for pedunculated papillomatous and sessile conjunctival lesions in a low-resource setting with extremely limited operating room access.

Methods: Adult patients with clinical diagnosis of conjunctival papilloma underwent complete ophthalmologic exam including anterior segment photography. After topical anesthesia and toluidine blue 1% instillation, the lesion was treated by pattern scanning photocoagulation using a duration time that varied from 20 to 100 ms and power from 600 to 1800 mW, treating the entire lesion surface with a 2 mm margin.
