Macular Pucker After Retinal Detachment Surgery

Abstract

To better understand postsurgical macular pucker in rhegmatogenous retinal detachment, we reviewed a consecutive series of 277 eyes in 268 patients in whom retinal detachment had spared the macular area and in whom no preretinal membrane with distortion of the retinal vessels had been present preoperatively. Postoperatively, 17 eyes (6.1%) developed obvious macular pucker; 260 eyes (93.9%) did not. Using the Mantel-Haenszel chi-square test, we found that patient age, preoperative vitreous hemorrhage, large retinal breaks of more than three disc diameters, and cryoapplication were significant precipitating factors of postoperative macular pucker. These findings are consistent with the view that dispersion of retinal pigment epithelial cells through the retinal break into the vitreous cavity is the major cause of this disorder. Minimal use of cryotherapy is recommended in treating elderly patients who have a large retinal break or a preoperative vitreous hemorrhage.
