Postoperative outcome of trans pars pklana vitrectomy in the treatment of posterior and intermediate uveitis

We performed standard pars plana vitrectomies in 17 eyes with uveitis which were complicated with vitreous opacities. Postoperatively, visual acuity was improved in 11 eyes(64.7%),maintained in4 eyes(23.5%) and decreased in 2 eyes (11.8%). Four weeks after vitrectomy, inflammatory cells were rarely noticed in the anterior vitreous of all eyes. We suggest that early surgical approach is of value for visual improvement in the management of uvitis eyes with vitreous opacity.

The Clinical Evaluation of Pars Plana Vitrectomy in various Ocular Disease

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.

Two Cases of Congenital Aniridia

Aniridia, the bilateral total or partial absence of the iris, is a rare congenital often hereditary anomaly which usually leads to blindness in adulthood due to secondary glaucoma and cataract formation. The authors experienced two cases of congenital aniridia associated with nystagmus, foveal hypoplasia, corneal pannus, cataract, secondary glaucoma and strabismus. Extracapsular cataract extraction and trabeculectomy was performed with satisfactory result. Therefore this case was presented with brief review of literatures.

Three Cases of Simple Ectopia Lentis in One Family

Ectopia lentis, Synonymously with Congenital dislocated lens, is defined as a dislocation of the ocular lens, of greater or less degree, based on a developmental anomaly. It occurs in three conditions, as an isolated anomaly, in association with ocular anomaly, and as a part of a systemic syndrome with other mesodermal, particularly skeletal anomalies. Among these, simple ectopia lentis is a hereditary autosomal dominant disorders without skeletal, connective tissue or metabolic symptomatology. Except for the dislocation of the lens, these eyes are in other respects grossly normal. Regarding its management, there is a continuing debate proponents of active surgical intervention to prevent future problems to those who will not remove the lens and advocates of conservative treatment because lens surgery can be difficult and has a high rate of intraoperative and post operative complication. Recently, the authours have experienced three patients with simple ectopia lentis, which occurred in one family with autosomal dominant inheritance and achieved satisfactory result surgically. Thus these cases are presented with brief review of literatures.
