Effects of scleral buckling and vitrectomy for familial exudative vitreoretinopathy / 中华眼底病杂志

ABSTRACT

Objective To observe the surgical effects of scleral buckling and vitrectomy for familial exudative vitreoretinopathy (FEVR).Methods 34 eyes of 27 patients with FEVR who underwent either scleral buckling or vitrectomy were enrolled in this study.There are stage 2B in 2 eyes (5.88％),stage 3B in 7 eyes (20.59％),stage4Ain 1 eye (2.94％),stage4Bin 16 eyes (47.06％),stage 5 in8 eyes (23.53％).5 eyes associated with rhegmatogenous retinal detachment.The surgical approaches had been chosen according to the disease stage,severity,extent and morphology of the proliferative membrane.13 eyes (stage 2B in 2 eyes,3B in 4 eyes,and 4 in 7 eyes) underwent scleral buckling and 21 eyes (stage 3B in 3 eyes,4 in 10eyes,and 5 in 8 eyes) underwent vitreoretinal surgery.The main outcome measurement was the anatomic status of the macula,which was recorded as attached,partially attached or remain detached.The mean follow up was (18.00 ± 14.61) months (range 4 to 60 months).Results Among 13 eyes received scleral buckling,the macula was attached in 2 eyes with stage 2B (15.38％),partially attached in 11 eyes (84.62％) including 4 eyes with stage 3B,1 eye with stage 4A and 6 eyes with stage 4B.Among 21 eyes received vitrectomy,the macula was attached in 8 eyes (38.10％) including 2 eyes with stage 3B,4 eyes with stage 4 and 2 eyes with stage 5;the macula was partially attached in 9 eyes (42.86 ％) inducing 4 eyes with stage 4 and 5 eyes with stage 5;the macula remained detached in 4 eyes (19.05％) including 1 eye with stage 3B,2 eyes with stage 4 and 1 eye with stage 5.Conclusion If the surgical approaches were chosen based on the stage of FEVR and the severity,extent and morphology of the proliferative membrane,the surgery is effective and beneficial to FEVR patients.
