ABSTRACT
Objective To compare the efficacy of pneumatic retinopexy and subretinal drainage in the treatment of primary rhegmatogenous retinal detachment(RD) in scleral buckling procedure.Methods Pneumatic retinopexy or subretinal drainage was applied during the scleral buckling procedure when lots of subretinal fluid existed.Results Twenty-three of 26 eyes(88.5%) were successfully reattached by pneumatic retinopexy during scleral buckling procedure for the repair of primary retinal detachment.New hole formation was the major complication for the surgical failure.One eye was fixed by another buckling procedure and the other two were treated by vitrectomy.Eleven of 12 eyes(91.7%) with primary RD were successfully managed by scleral buckling procedure and subretinal fluid drainage.Subretinal hemorrhage occurred in one eye after subretinal drainage.Conclusion Pneumatic retinopexy can substitute subretinal drainage in the repair of primary rhegmatogenous retinal detachment when plenty of subretinal fluid exists.
ABSTRACT
Objective To verify the significance of the morphological changes of the macula and its relationship to visual function by using optical coherence tomography (OCT) after scleral buckling procdure. Methods The macula of retinae of 68 patients (70 eyes) with reattached retinae after scleral buckling operation for retinal detachment were examined by OCT to scan the macula through fovea vertically and horizontally. Results Among the 70 eyes, 22 eyes revealed normal macula with thickness of neurosensory retina meant (146.47?20.59) ?m. In the other 48 eyes (68.60%) with abnormal macula, 19 eyes showed extensive subretinal interspace, 9 eyes showed local subretinal interspace, 8 eyes showed macula edema, 4 eyes showed thin macula, 4 eyes showed subretinal proliferation and 4 eye showed epiretinal membrane over macula. In the normal macular structure group under the OCT, the visual acuity (VA) of the operated eyes was more than 0.3 in 6 eyes 2 weeks after operation and in 14 eyes 3 mons after operation. In the macula edema group, the VA was more than 0.3 in 1 eye 2 weeks after opoeration and 2 eyes 3 mons after operation. In the subretinal interspace group, the VA was more than 0.3 in 5 eyes 2 weeks after operation and in 23 eyes 3 mons after operation. The proportions of the numbers of operated eyes with the VA more than 0.3 after 3 mons of the operation in macular normal group subretinal interspace group and other macular disease group were significantly different (? 2=18.91, P
