[Vitrectomy-laser-gas for treating optic disk pits complicated by serous macular detachment].

PURPOSE: Optic nerve pit is a rare congenital anomaly. In two third of the patients, the severity of the disease is increased by the apparition of a serous macular detachment, which may compromise the visual prognosis. The aim of this study is to propose a therapy appropriate to such 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, peripapillary photocoagulation and intravitreal injection of gas. The mean postoperative follow-up period was 9.5 months.

RESULTS

Therapy success was based on anatomical and functional results. Serous macular detachment reattached in 7 patients out of 10 and a recurrence was observed in one case. Visual acuity improved from 0 to 18 lines of the EDTRS chart (mean increase: 6.7 lines).

CONCLUSION

These results confirm that intraocular surgery including vitrectomy-photocoagulation-gas injection is a valuable treatment for serous macular detachment associated with optic nerve pit.
