[Pars plana capsule resection for therapy of ocular hypotension syndrome caused by capsule shrinkage with ciliary body detachment].

A rare complication of extracapsular cataract extraction is hypotony due to capsular shrinkage, with consequent ciliary body detachment. A classic hypotony syndrome with progressive loss of visual acuity was observed in two patients, one with extracapsular aphakia and one with extracapsular pseudophakia. Each presented with a fibrotic, shrunken capsular bag and a secondary cataract. As the contraction forces appeared to derive predominantly from the periphery of a circumferentially fibrotic capsular bag, the lens capsule was operatively removed. A pars plana approach was used to access the equatorial capsular ring and visualize the ciliary body processes. The intraocular lens appeared to be stable and remained in situ. Postoperative elevation of intraocular pressure occurred, with improvement of hypotony symptoms, especially in the fundus. Visual acuity also improved, but was limited due to secondary cystoid edema.
