Abstract

Operation on vitreous body has been almost forbidden till the past few years. However, after the report on pars plana vitrectomy in early 1970's, it has been received favorably as effective operation for treatment of many diseases of vitreous body. So, the clinical and statistical evaluation of the 60 pars plana vitrectomies using a device of VISC X which were operated at the Dept. of Ophth. St. Mary's Hospital, Catholic Medical College from July, 1977 to April 1979 was done. The follow up period ranged from 2 wks to 21 months. The results were as follows; 1. Among the four major causes requiring pars plana vitrectomy, the highest percentage was occupied by Trauma (33 cases-55.0%) followed by diabetic retinopathy (11 cases-18.3%), hypertensive retinopathy (3 cases-5.0%) and central retinal vein occlusion (3 cases-5.0%). 2. Postoperative improvement of visual acuity was seen in 26 cases (43.3%). There was no change in vision in 17 cases (28.3%) and decrease of visual acuity occured in 17 cases (28.3%). Vitreous opacity and hemorrhage patients without proliferative changes showed improvement in 55.2% where as patients with proliferative changes showed improvement in only 32.3% of cases. 3. The complications during operation were vitreous hemorrhage (7 cases-11.7%), hyphema (4 cases-6.7%), retinal detachment (3 cases-5.0%) and traumatic cataract (2 cases-3.3%). The postoperative complications were ocular hypotonY(11 cases-18.3%), vitreous hemorrhage (9 cases-15.0%) and retinal detachment (9-cases-13.3%). We found that pars plana vitrectomy using a device of VISC X is effective method in rarious cases of vitreous diseases with or without proliferative change which has not been able to treat effectively before.
