Long-term Clinical Outcome of Vitrectomy for the Treatment of Optic Disc Pit Maculopathy

ABSTRACT

PURPOSE: To evaluate the long-term outcomes of optic disc pit maculopathy after vitrectomy. METHODS: We evaluated retrospectively the medical records of eight patients with macular retinal detachment or retinoschisis who underwent vitrectomy due to optic disc pit maculopathy. The best-corrected visual acuity and optical coherence tomography findings were analyzed after surgery. RESULTS: Eight eyes of eight patients (two male and six female) were enrolled. The mean best-corrected visual acuity was 0.76 log MAR, the mean age was 42.8, and the mean follow-up period was 56 months (range 8–120 months). At baseline, retinoschisis was observed in all eight eyes. Six eyes had serous retinal detachment of the macula. Vitrectomy for a complete posterior vitreous detachment was performed. Additional internal limiting membrane peeling and tamponade were performed in six and four eyes, respectively. After surgery, serous retinal detachment was gone in all eyes (100%) at a mean of 22.8 months (range 18 days–60 months). Three of eight eyes (37.5%) showed the disappearance of retinoschisis at a mean of 6.8 months (range 1.7–21 months), but the remaining patients still had retinoschisis at the final visit. Ocular complications were full-thickness macular hole and iatrogenic retinal detachment in each case. The final corrected visual acuity improved to 0.29 logMAR. CONCLUSIONS: Vitrectomy is an effective treatment for patients with optic disc pit maculopathy. It achieved anatomical and visual improvements over a long period of time. However, retinoschisis due to inner retinal fluid remained in many patients.
