The Outcomes of Intravitreal C3F8 Gas Tamponade Combined with Laser Photocoagulation Treatment for Optic Disc Pit Maculopathy

Abstract Purpose: To share the anatomical results and visual outcomes of intravitreal gas tamponade combined with laser photocoagulation treatment for optic disc pit maculopathy (ODPM). Methods: Intravitreal gas tamponade combined with laser photocoagulation treatmentwas performed on six consecutive patients with ODPM. A 0.3-mL of 100% octafluoropropane (C3F8) gas was injected intravitreally. The patients were then asked to maintain prone position until the C3F8 gas disappeared. Laser photocoagulation was performed the day after the procedure. The outcomes were determined by spectral-domain optical coherence tomography and best-corrected visual acuity (BCVA). Results: In the present study, visual improvement and reduction in serous macular detachment was observed in 83% of the ODPM patients. Complete retinal reattachment was achieved in 66% of the ODPM patients. In one patient, no regression was observed after the repeated treatment and pars plana vitrectomy was performed. The final BCVA improved in five eyes and unchanged in one eye. No postoperative complications were observed during the follow-up period in any patient. Conclusions: Intravitreal C3F8 gas tamponade combined with laser photocoagulation procedure is an effective, minimally invasive, and cost-effective treatment method for ODPM.
