VITRECTOMY-PHOTOCOAGULATION-GAS TAMPONADE FOR THE TREATMENT OF SEROUSMACULAR DETACHMENT ASSOCIATED WITH OPTIC-NERVE PITS

Purpose Optic nerve pit is a rare congenital anomaly. In two third of the patients, the severity of the disease is increased by the appariti on of a serous macular detachment, which may compromise the visual pro gnosis. The aim of this study is to propose a therapy appropriate to s uch complication. Methods A prospective study was performed including 10 patients with a serous macular detachment caused by optic nerve pit . All patients underwent intraocular surgery including vitrectomy, per ipapillary photocoagulation and intravitreal injection of gas. The mea n postoperative follow-up period was 9.5 months. Results Therapy succe ss was based on anatomical and functional results. Serous macular deta chment reattached in 7 patients out of 10 and a recurrence was observe d in one case. Visual acuity improved from 0 to 18 lines of the EDTRS chart (mean increase: 6.7 lines). Conclusion These results confirm tha t intraocular surgery including vitrectomy-photocoagulation-gas inject ion is a valuable treatment for serous macular detachment associated w ith optic nerve pit.
