RESUMO
We reviewed the hospital records of 104 consecutive eyes in 101 patients who underwent pars plana vitrectomy at Presbyterian Medical Center from January 1993 to December 1995 and studied the postoperative visual acuity and postoperative complications. Possible indications for pars plana vitrectomy were follows: complications of proliferative diabetic retinopathy (30.7%),complications of other types of proliferative retinopathy except proliferative diabetic retinopathy(25.0%),complications of anterior segment surgeries (14.4%), complex retinal detachments(8.7%), intraocular inflammations and uveitis (8.7%), macular diseases (6.7%), and complications of ocular trauma (5.8%), Regarding postoperative final visual acuity, 53 eyes(51.0%) were improved, 30eyes(28.8%) were stabilized, 21eyes(20.2%) were worsened. Intraoperative or postopertive cataract, retinal breaks or retinal detachment were most frequent complications. We expected that pars plana vitrectomy might be indicated in various ocular diseases containing proliferative diabetic retinopathy.
