COMPARATIVE STUDY OF GENDER VARIATIONS IN OCULAR PARAMETERS BY A-SCAN IN AGE MATCHED ADULTS

Abstract

PURPOSE Multiple ocular diseases are significantly correlated with ocular parameters. Gender is well thought-out to be a predictor of the ocular biometrics. Biological parameters like anterior chamber depth, lens thickness, axial length are of great significance in calculation of IOL power before cataract surgery, diagnosis and management of angle closure glaucoma, staphyloma and various other conditions. These parameters are significant variables for refractive errors also where the A scan biometry is most widely used method for measurement of these parameters. The purpose of this study is to compare gender differences in axial length, anterior chamber depth and lens thickness in age matched adults. AIMS AND OBJECTIVES ● To compare gender differences in axial length in age matched adults. ● To compare gender differences in anterior chamber depth in age matched adults. ● To compare gender differences in lens thickness in age matched adults. MATERIAL AND METHODS A cross sectional comparative study conducted in Department of Ophthalmology in R.L.J Hospital and Research Centre attached to Sri Devaraj Urs Medical College from December 2019 and May 2021. A total of 192 eyes of 48 males and 48 females were evaluated. After obtaining consent, demographic details were noted & then subjected for detailed ophthalmic examination of both eyes including Visual acuity, Slitlamp biomicroscopy, IOP by Goldmann xiii Applanation Tonometry, Fundus examination and Axial length, Anterior chamber depth and Lens thickness measurement by A-scan using contact technique. RESULTS Mean axial length among males and females was 23.78 ± 0.84mm and 22.65 ± 0.95mm respectively. Mean axial length among males was significantly higher in comparison to females. Mean anterior chamber depth among males and females was 2.52 ± 0.15 mm and 2.48 ±0.12 mm respectively. Statistically insignificant results were obtained while comparing the mean anterior chamber depth among males and females. Mean lens thickness among males and females was 4.72 ± 0.38 mm and 4.82 ± 0.31mm respectively. Statistically insignificant results were also obtained while comparing the mean lens thickness among males and females. CONCLUSION The mean axial length among males is higher compared to females, while other parameters may show variable results among gender. Our study concluded that the normative data obtained can help in accurate assessment of ocular biometry and different pathological conditions of eye.
