Analysis of the relative factors for rhegmatogenous retinal detachmort associated with choroidal detachment with macular hole in high myopia

Abstract

Objective To evaluate the risk factors and therapy for rhegmatogenous retinal detachment (RRD)associated with choroidal detachment(ChD)with macular hole in high myopia.Method 10 consecutive eyes (group A)with rhegmatogenous retinal detachment associated with choroidal detachment with macular hole in high myopia were reviewed, and 12 similar eyes(group B)without choroidal detachment in the same period were enrolled as controls.Age of onset, course of disease, degree of myopia, intraocular pressure, extent of RD,retinal reattachraent status and visual acuity were compared in all patients.Rusults In group A,the average age of onset is older, the degree of myopia is higher, the intraocular pressure is lower, and RE) is more extensive compared with group B (P <0.05).The proportions of retinal reattachment after first pars plana vitrectomy with silicon oil were similar:the percentage in group A is 80%, in group B is 83%.But the proportion of visual acuity after surgery better than 0.02 in group A is lower than that of group B(P=0.048).Conelusion RRD -ChD with macular hole in high myopia is often seen in old patients with seriously high myopia, low intraocular pressure and extensive retinal detachment.Although retinal reattachment status after first pars plana vitrectomy with silicon oil are similar,the visual acuity after surgery is lower in patients associated with ChD compared with patients without ChD.
