To evaluate the clinical outcomes after gas tamponade without vitrectomy for retinal detachment associated with an optic disc pit using optical coherence tomography (OCT).
Intravitreal gas injection was performed on 8 consecutive patients (mean age, 35.0 years; range, 15 to 74 years) with unilateral macular detachment associated with an optic disc pit. An injection of 100% SF6 gas, whose volume was 0.3cc, was carried out without anterior chamber tapped. Patients treated with gas injection were instructed to remain face-down for 5 days.
Complete retinal reattachment after only gas tamponade was achieved in 4 out of 8 eyes. The mean number of gas injections was 1.8. The mean best-corrected visual acuity before and after the treatment with gas was 0.28 and 1.02, respectively. The period required for reattachment after final treatment of gas was 12 months. There were no incidences of recurrence after complete reattachment by gas tamponade in any cases during follow-up over an average of 94 months (range, 64 to 132 months).
Gas tamponade seems to be an effective alternative method for macular detachment associated with an optic disc pit, although the mechanisms of optic disc pit maculopathy are still unknown.
