Abstract
Introduction: Retinal vein occlusion is characterized by retinal and subretinal haemorrhages, macular oedema, and a varying degree of retinal ischemia. There is an increased risk with cardiovascular diseases but not all people with retinal vein occlusion reflect aggressive form of systemic diseases. In that situation, the role of ocular biometry and refraction is still essential to be studied.
Objectives: To compare the ocular biometry and refractive error of affected eyes of patients with retinal vein occlusion to their fellow eyes and the control group.
Methodology: This is a cross-sectional comparative study carried out at B.P. Koirala Lions Centre for Ophthalmic Studies. Ethical clearance was obtained from the institutional review committee of institute of Medicine. The calculated sample size was 60. After obtaining informed consent, 67 patients with retinal vein occlusion and 67 controls were enrolled using purposive sampling technique. Refractive error was determined using an auto-refractometer (Topcon KR-800). Keratometry, Anterior chamber depth, and Axial length were measured using IOL-Master-500. Different statistical test like t-test, chi-square test and ANOVA were used to analyse the data.
Results: The eyes with retinal vein occlusion were not significantly different either from fellow eyes or the control group in biometric indices like average keratometry, anterior chamber depth, and axial length. Significant hyperopia was found among central retinal vein occlusion group as compared to the fellow eye.
Conclusion: Biometric indices and refractive error in retinal vein occlusion cases were not significantly different from the control group. Central retinal vein occlusion was found to be significantly predisposed in more Hyperopic eyes as compared to fellow eyes.
