Clinical observation of external-route microsurgery for pseudophakic retinal detachment

Abstract

Objective To evaluate the clinical efficacy of external-route microsurgery for pseudophakic retinal detachment. Methods In 21 patients (22eyes) with pseudophakic retinal detachment,the buckling bands were preplaced,then under surgical microscope the suture of buckling and circling were placed,and drainage of subretinal fluid,retinal cryotherapy,buckling,examination of locating the holes,circling and intraocular injection of gas were performed.And the effects were observed during the follow-up. Results Retinal reattachment was achieved in 18 eyes after the primary surgery and in 3 eyes after the secondary surgery,with the final rate of reattachment was 95.5％.The postoperative visual acuity improved in 18 eyes,equaled in 2 eyes,and decreased in 2 eyes.The best-corrected visual acuity was ≥0.3 in 9 eyes.No intraocular lens shifted and serious complication occurred after surgery. Conclusions The external-route microsurgery for pseudophakic retinal detachment fits for the patients whose pupil and relative brightzone of capsule ≥6mm and PVR≤C1,and it is simple,convenient,safe,reliable,and effective.
