ABSTRACT

Objective: To evaluate the relationship of blood groups with Age Related cataract & Rhesus systems. And find out if there is any genetic relationship. Methods: A prospective randomized trial was done in 193 individuals from 12 th jan 2013 to 25 th 2014.out of this 123 were cataracts and 70 normal controls and their ABO and Rhesus blood group were determined by standard method in the Department of Transfusion Medicine & Ophthalmology Department of L.N. Medical College and Research Centre, Bhopal . Incidence of Cataract was analysed in different blood group system. Result: Among the 123 patients, blood group A was found in 22.7%, B in 26.01% ,O in 36.58%, AB in 14.63% and 82.93 % patients were Rhesus positive and 17.07 % Rhesus negative . The number of cataract patients in blood group A was increased by 4.19% and decreased by 3.92% in blood group AB and there was no statistical difference between the control and patients in blood group B and blood group O. It was observed that the occurrence of cataract was increased by 4.36% in Rhesus positive patients where as it is decreased by 4.35 % in Rhesus negative patients as compared to the controls. Conclusion: In this study, since the increase in number of cataract patients in blood group A & RH positive is nearer to significant value it is concluded that the assessment may be carried out in larger number of population.
