Study of Visual Function in Myopic Young Adults

Objectives The objective is to study visual function among young myopic adults and its association with the degree of myopia. Material and Methods A six-month (from January 2024 to June 2024) Prospective Cross-sectional study was conducted. A total of 75 participants with a mean age of 20.24 years were included in the study. To rule out any pathology or retinal abnormalities, each participant underwent a complete eye examination prior to the visual function test. The degree of myopia was assessed to identify any significant differences in visual functions, including colour vision, near point of convergence, near point of accommodation, contrast sensitivity, visual field, axial length, and stereopsis. Results The statistics on visual function for the eye power categories are reported as mean, standard deviation, and standard error. The means were analysed using one-way analysis of variance (one-way ANOVA) and the Bonferroni ‘t’ test for post-hoc multiple comparisons. The mean age of participants was 20.24 years, and the distribution of myopia was done as -1.75D and less, -2D to -3.75D, -4D to -5.75D, and -6D and above. The statistical analysis revealed significant variations in axial length (P < 0.001) and stereopsis (P = 0.002). However, near point of convergence (P=0.101) and near point of accommodation (P=0.773) did not show any difference. Conclusion The study shows that adults with different degrees of myopia have increased visual function variation requiring proper care.
