The Distribution of Iris Colour and Its Relationship to Myopiain Bangladeshi Patients

Abstract

Background: Myopia, or nearsightedness, affects a large percentage of the population and is typically identified in those under the age of 20. Having myopia makes it difficult to see far away. While you have no issue seeing nearby items, such as those used to indicate aisles in a grocery store, you may have trouble seeing further away ones, such as road signs. Objective: In this study our main goal is to evaluate the distribution of iris colour and its relationship to myopiain Bangladeshi patients. Method: This cross-sectional study was carried out at tertiary hospital from March 2020 to December 2021, researchers from several fields and sessions worked together on a single unified study. There were a total of 100 people, with a best corrected visual acuity (BCVA) of 6/6, and ages ranging from 11 to 25 years old. Patients were limited to no more than six hours of television every day. All three degrees of myopia (mild, moderate, and severe) were covered. Results: During the study, 51% belong to 10-15 years followed by 35% belong to 16-20 years and 14% belong to 21-25 years. In addition, among patients mild 55%, moderate 21%, and severe 24% myopia. Screen time, significantly associated with myopia. 40% who had screen time was 1-2 hours had severe level myopia. Followed by 45% who had screen time was 2-4 hours had severe level myopia and 50% who had screen time was 4-6 hours had severe level myopia. 66% who had mid-level myopia had grade I Irish color. Followed by 56% who had moderate level myopia had grade I Irish color and 50% severe level myopia had grade I Irish color. 66% who had simple myopia had grade I Irish color. Followed by 55% who had curvatural myopia had grade I Irish color. Conclusion: Darker iris color was linked to higher myopia-related refractive errors, even when other known myopia-related risk variables were taken into account.
