Title

GAS TAMPONADE FOLLOWED BY LASER TREATMENT FOR MACULAR RETINAL DETACHMENT SECONDARY TO OPTIC PIT

Introduction

Purpose: To describe anatomic and visual outcomes associated with intravitreal injection of perfluoropropane (C3F8) followed by laser treatment for macular retinal detachment secondary to optic disc pit (ODP).

Methods

Methods: A single center, retrospective study. Medical records were reviewed of all patients treated at a tertiary retina referral center between 2011 and 2018 for congenital optic disc pit (ODP)-associated macular detachment with intravitreal injection of 100% C3F8 followed by retinal photocoagulation along the temporal margin of the optic disc as the initial treatment strategy for the ODP-associated macular detachment.

Results

Results: Six patients with ODP-associated macular detachment during the study period were identified, with postoperative follow-up ranging from 4 to 52 months. Spectral domain optical coherence tomography (SD-OCT) demonstrated complete resolution of fluid in two cases, with no recurrence after 26 and 100 weeks of follow-up. No additional procedures were performed in either case. Partial fluid reabsorption occurred in the remaining 4 cases. One patient demonstrated no anatomic improvement and was treated with pars plana vitrectomy. Best-corrected visual acuity (BCVA) improved after surgery, considering the last follow-up visit of each case.

Discussion

Conclusion: Intravitreal injection of 100% C3F8 followed by photocoagulation along the temporal margin of the optic disc margin was associated with anatomic and visual improvement in most cases, and represents an alternative therapeutic approach for ODP-associated macular detachment.
