Abstract

Background: Myopia (nearsightedness) is a very common condition in which people can’t see the object farther away clearly. It occurs when eyeball grows too long from front to back or when there is a problem with the shape of the cornea resulting in headache and eyestrain. Objectives: To determine the stereoacuity in different degree of myopia with and without correction. Methodology: A comparative crosssectional study was conducted at the Ophthalmology Department of University of Lahore Teaching Hospital from July 2021 to November 2021 in the duration of 4 month. A total of 80 subjects of age ranges from 20- 30 years of either sex was selected by non-probability convenient sampling technique. All the patients fulfill the inclusion criteria and having myopia of varying degree mild myopia from 0.5-2.0 D, moderate myopia from 2.0 D- 6.00D and severe myopia >6.0 D were the part of the study. After obtaining the best corrected visual acuity the stereoacuity was evaluate with TNO stereoacuity test. SPSS version 22 was used to analyzed the result. Results: The mean age of the patients was 24.49±2.08. The frequency of female was 71.25% (n=57) and the male was 28.75% (n=23) respectively. Out of 80 subjects there was 58.75% (n=47) patients with mild myopia, 27.5% (n=22) with moderate myopia and only 13.75% (n=11) patients with severe myopia. Paired sample t- test shows a significant association of stereoacuity with and without correction in all degree of myopia. Chi-square test also shows a significant difference among different degree of myopia. Conclusion: There was statistically significant difference of stereoacuity among mild, moderate and severe myopia and also shows a significant improvement of stereoacuity with and without correction in all degree of myopia.
