Abstract

Introduction: The purpose behind conducting this study was to determine if hypertension increases the risk of cataract, to find out common morphological types of cataract in hypertensive patients, to determine relation between grade of hypertension and grade of nuclear sclerosis and to compare prevalence rates of cataract in hypertensive patients on anti-hypertensive drugs and those not on anti-hypertensive drugs.
Materials & Methods: Comparative study of cataract in hypertensive patients and non- hypertensive patients was crriedout in in Department of ophthalmology at Ashwini Rural Medical College, Kumbhari, Solapur with 300 eligible participants.
Results: This was a comparative study with 156 hypertensive and 144 non-hypertensive patients. Prevalence of cataract was found to be 79.53%. Prevalence of cataract was significantly higher in eyes of hypertensive patients as compared to eyes of non-hypertensive patients; (87.83% and 70.8% respectively, with p-value<0.0001). Significant association was found between high systolic BP and cataract. (χ2=23.82, df= 1, p<0.0001). Nuclear cataract was the most common morphological type in eyes of hypertensive patients (50.4%). However, posterior sub capsular cataract was more common in eyes of hypertensive patients as in eyes of non-hypertensive patients (28.6% and 23.3%). No significant relation was found between grade of hypertension and grade of nuclear sclerosis (χ2 = 4.33, df= 3, p=0.23). No significant difference between them was found in our study. (Z=0.10, p=0.92).
Conclusions: Risk of cataract is higher in hypertensive patients as compared to non-hypertensive patients. Relation between grade of hypertension and grade of nuclear sclerosis and role of anti- hypertensive drugs must be further explored.
