23 Gauge Vitrectomy, Endolaser, and Gas Tamponade Versus Vitrectomy Alone for Serous Macular Detachment Associated With Optic Disc Pit.

Abstract

To evaluate the clinical outcomes of 23 gauge vitrectomy, endolaser, and gas tamponade vs vitrectomy alone for the management of serous macular detachment associated with optic disc pits. Retrospective, comparative case series. Seventeen eyes of 16 patients who underwent 23 gauge transconjunctival sutureless pars plana vitrectomy (PPV) for serous macular detachment associated with optic disc pits were evaluated in this study. Complete ophthalmologic examinations including optical coherence tomography (OCT) and fundus autofluorescence were evaluated at the baseline and during the postoperative follow-up period. Ten eyes of 9 cases that underwent 23 gauge PPV, endolaser, and gas tamponade were allocated to Group 1, and 7 eyes of 7 cases that underwent 23 gauge PPV alone were allocated to Group 2. There were 6 male and 3 female patients in Group 1, and the average age of patients was 24.7 years. There were 5 male and 2 female patients in Group 2 and the average age of patients was 22.1 years. There was no difference in the postoperative visual acuity (P = .7) and postoperative central foveal thickness (P = .5) between the 2 groups. The mean time of the subretinal fluid resolution was significantly shorter in Group 1 than in Group 2. OCT showed the inner layer separation improved before than serous retinal detachment. Preoperative features of the inner/outer segment junction correlate well with improvement of postoperative visual acuity. Vitrectomy alone without gas tamponade and laser photocoagulation is a safe and effective method for management of serous macular detachment resulting from optic disc pits as well as combined surgery.
