Pak J Ophthalmol Jan ;14(3):108-13.

Reported in this article is a review of 1159 cases of retinal reattachment surgeries performed by the author at `Al-Shifa Trust Eye Hospital` between the period of March 1992 and June 1997. All cases included in the study had a rhegmatogenous component. There were 87(7.5%) children under the age of 15 years. There were 454(39.17%) females and 705(60.82%) males. Sixty-seven (5.78%) of the patients had bilateral retinal detachment. The main group comprised aphakes, 622(53.66%), 173(14.9%) were pseudophakes, 136(11.7%) had myopia of variable degree, 74(6.4%) had a history of blunt trauma, 150(12.9%) had Idiopathic rhegmatogenous retinal detachment probably related to posterior vitreous detachment 10(0.86%) patients had a corneal graft done in the past 4 patients had a chorioretinal coloboma with a rhegmatogenous component and 23(1.98%) patients had giant retinal tears. 619(53.4%) patients underwent conventional retinal reattachment surgery, 14(1.20%) patients had pneumatic retinopathy, while the rest had a combined vitrectomy and retinal detachment surgery done. 138(11.9%) patients had primary vitrectomy done. 162(14%) patients had reattachment surgeries done elsewhere. Silicone oil was used as internal tamponade in 315(27%) cases. Other agents used for internal tamponade were sulphur hexaflouride gas (SF6) and air. The final anatomical success rate was around 84%. 6112 or better vision was obtained in 212(18.3%) patients. The main cause of surgical failure in this study was proliferative vitreoretinopathy (PVR) which was present in 31% of the patients. Other pre-or postoperative poor prognostic indicators were uveltis, vitreous hemorrhage and hypotony. The main purposes of the study were to assess the results in the light of various other studies, to identify poor prognostic factors in our setting, to touch upon the recent trends in vitreoretlnal surgery and to highlight preventive measures.
