Purpose: Optic Disc Pit Maculopathy has a poor visual prognosis left to its natural course. We present the functional and anatomic results of 11 patients managed with vitrectomy-laser-gas from 1996 to 2002.
Methods: Retrospective interventional study including 11 eyes with Optic Pit Maculopathy. Three cases had been treated previously with laser and gas. Pre and postoperative visual acuity (VA), Optical Coherence Tomography (OCT), time from onset, angiography and retinographies were registered. Pars Plana Vitrectomy, posterior hyaloid dissection, temporal peripapillary diode laser previous to retinal reapplication and C3F8 15 % injection were performed in all cases.
Results: Preoperative VA ranged from 20/400 to 20/60, mean 20/120. Time from onset ranged from 2 to 40 months, wih a mean of 13 months. In all cases VA improved, ranging from 1 to 8 lines of vision ( mean 4.4 lines, p < 0.05). Mean final VA was of 20/30 ( ranging from 20/100 to 20/20). Preoperative OCT was performed in 7 cases and confirmed the bilaminar structure of the macular detachment. Postoperative OCT showed retinal reapplication in all cases after a mean period of time of 7 months. Mean follow-up was 24 months. Recurrence was observed in two cases.
Conclusions: In our series the vitrectomy-laser-gas procedure for Optic Pit Maculopathy improved vision and achieved satisfactory anatomic results in all 11 cases included . However, the low incidence of this entity makes it difficult to obtain big series needed to determine the efficacy of this and other treatment modalities and finally suggest a procedure of choice.
