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. Patients were examined weekly for a month then monthly and underwent retreatment as necessary.

Results: Six patients and seven eyes that had clinically significant non-malignant pedunculated or sessile papillomatous lesions were treated. All lesions responded to treatment, with complete resolution after an average of 2.3 sessions. Procedures were well tolerated with only minor mild discomfort persisting up to two days post-treatment. Patients were followed for a mean follow-up time of 13 months with no recurrences reported.

Conclusion: Short-term results of the pattern scanning laser photocoagulation approach, with toluidine blue for papillomatous conjunctival lesions are favorable with a 100% success rate in this cohort. This rate is comparable to surgical excision. This novel strategy proved to be a less resource intensive alternative that not only could demonstrate its usefulness in settings with chronic operating room shortages, but also in recurrent cases. Longer follow-ups with a larger sample size and cost-analysis are necessary to confirm our findings.
