Abstract

Abstract: : Purpose: To evaluate the process of retinal reattachment in pit–macular syndrome after vitrectomy. Methods: We performed vitrectomy with SF6 gas tamponade in 7 eyes of 7 patients (male: 3 cases female:4cases)with pit–macular syndrome. Patient’s age ranged 30 to 73 (mean, 53.4 years). Patients were at face down position at least 3 days after surgery. No case was treated by photocoagulation. Postoperative follow–up period was 7 to 44 months (mean, 26.6 months). One eye developed macular hole before surgery and it was closed by vitrectomy and postoperative gas injection. Another eye developed macular hole postoperatively, which was closed by fluid gas exchange. We observed cross–sectional images of the posterior pole before and after surgery by repeated examination of optical coherence tomography (OCT). All 7 patients had visual improvement more than two lines. Results: After vitrectomy, it took 7 to 17 months (mean, 11.8 months) to obtain complete attachment of retina in 5 of 7 eyes. Two eyes still have macular detachment at 4 months and 6 months. OCT showed early resolution of retinoschisis and gradual absorption of macular detachment. Postoperative fluid gas exchange (1 to 4 times) was effective to obtain the complete reattachment of retina in 4 of the 5 eyes. Conclusions: It takes long term to obtain complete retinal reattachment in pit macular syndrome. Repeated fluid gas exchange was effective to promote reattachment and closure of macular hole.
