RESUMEN
PURPOSE: To evaluate clinical efficacy of combined sulphur hexafluoride (SF6) gas tamponade and laser photocoagulation for optic disc pit maculopathy (ODPM). METHODS: Eleven eyes of nine patients with optic disc pit maculopathy were treated with intravitreal injection of 0.6 ml 100% sulphur hexafluoride (SF6) combined with laser photocoagulation treatment. Patients were followed up for a mean of 28.54 months (range of 14-57 months) after treatment. The anatomical success was shown by optical coherence tomography (OCT) and the functional outcome was judged by best corrected visual acuity. RESULTS: Treatment with SF6 gas tamponade followed by laser photocoagulation in OPDM patients resulted in resolution of subretinal fluid (SRF) in 82% of eyes after single injection. Repeated injection was needed in two eyes to achieve resolution of SRF. Visual acuity improved significantly from a mean of 0.83 ± 0.14 logMAR preoperatively to a mean of 0.26 ± 0.11 logMAR postoperatively. Visual acuity stayed stable throughout the follow-up period. CONCLUSIONS: SF6 gas tamponade combined with laser photocoagulation represents simple, effective, minimally invasive treatment option for ODPM without vitreomacular traction. Repeated injection was required in some patients.
