Clinical Evaluation for 28 Cases of Vitreous Surgery: A preliminary report

ABSTRACT

Vitreous surgery has become a widly practiced procedure for use in the variety of pathological conditions in the anterior and posterior semgment of the eye. The goal of the vitreous 'surgery is to clear the optic pathway and restore the anatomy and function of the eye. Vitreous surgery was performed in 28 eyes using the O'malley ocutome from April, 1980 to October, 1980. Among the 28 eyes, 14 eyes received anterior segment surgery and the other 14 eyes received posterior segment surgery. The follow up period after surgery ranged from 3 weeks to 7 months and the average period was 4 months. The conditions requiring surgery were as follows 9 eyes had Reconstruction of anterior segment after trauma; 4, removal of pupillary membrane due to chronic uveitis and after cataract; and 1, anterior vitrectomy with removal of subluxated lens. As for the causes of posterior segment surgery, 5 eyes had trauma of eyeballs; 3, hypertensive retinopathies; 2, vitreous opacity with retinal detachment; 1, diabetic retinopathy; 1, central retinal vein occlusion; 1, nonmagnetic intraocular foreignbody; and 1, lost lens nucleus into the vitreous. The improvement of visual acuity after surgery was seen in 14 eyes (50%), 9 eyes in anterior segment surgery and 5 eyes in posterior segment surgery. The complications during operation were vitreous hemorrhage (1 eye; 3.5%), retinal detachment (2 eye; 7%), and traumatic cataract (1 eye; 3.5%). Postoperative complications were phthisis bulbi (1 eye; 3.5%), and cataract (1 ; 3.5%). We found that vitreous surgery is not only useful to removal of the various pathologic conditions of vitreous through the pars plana approach but in anterior segment as an emergency procedure at the time of trauma and vitreous loss during anterior segment surgery.
