Clinical Risk Factors for Proliferative Vitreoretinopathy-II

Abstract

Purpose: To evaluate clinical variables as risk factors for proliferative vitreoretinopathy (PVR).

Material and Methods: This cross sectional comparative study was conducted at Khyber Institute of Ophthalmic Medical Sciences, Hayatabad Medical Complex, Peshawar from 1st August 2002 to 31st Dec. 2002. Fifty patients of rhegmatogenous retinal detachment (RRD) were included randomly in this study. They were evaluated for the presence of both risk factors and PVR grading. Chisquare test was used to measure the difference in exposure rates and odds ration was calculated to estimate the strength of association between risk factors and outcome.

Results: Large retinal breaks (p<0.05) was found to be statistically significant risk factor for PVR grade C or more. The exposure rates in myopia >5D, signs of anterior uveitis, vitreous hemorrhage and number of retinal breaks were statistically not significant (p>0.05).

Conclusion: Large retinal breaks are associated with high risk of high grade PVR, so this factor should be considered as important prognostic factor in the management of RRD.
