ASSOCIATION BETWEEN BLOOD GROUPS AND REFRACTIVE ERRORS
Abstract
Objective: To find out association between blood groups and refractive errors and to overcome the problems producing due to this association by proper counselling.
Study Design: Descriptive cross sectional study.
Method: This study was conducted at refraction clinic, College of Ophthalmology & Allied Vision Sciences from 15th September 2015 to 15th December 2015. A total of 50 patients having age group 15-40 years of both genders were enrolled in the study. The patients having other eye diseases and blood dyscrasias were excluded from the study. The patients were selected using non‑probability convenient sampling. The data was analyzed using SPSS 20.0.
Results: Out of 50 patients, 30 patients (60%) of myopia were presented between 15 to 35 years of age. No hyperopic patient was present between 40 to 50 years of age. 16(32%) out of 50 patients were having blood group O and myopia while only 12(24%) out of 50 patients were associated with blood group A and B. Only 3(6%) hyperopic patients were having blood group A and O while 4(8%) were associated with blood group B.Â
Conclusion: Blood group O shows slight pre-dominance to myopia while other blood groups showed no specific association with other refractive errors.
Key words:Â Blood groups, refractive errors, pre-dominance.
