Abstract : Individuals with refractive errors are most commonly found having convergence insufficiency (CI) but in order to know its relationship with the myopia, research is needed. For this purpose this study was conducted at the Ophthalmology Department of Hayatabad Medical Complex, Peshawar to investigate the rate of occurrence of CI in patients having myopia and also to find whether increasing myopis plays any role that cause measurable changes in convergence function. It was a cross-sectional study that analyzed 61 myopic patients by assessing their refractive and binocular vision evaluation, near point of convergence (NPC) and positive fusional vergence (PFV) in detail. SPSS version 26 was used for the data analysis. 31.1% of the patients was found to have CI with more frequency present in those who have higher level of myopia (ranging from 22.2% in mild cases to 41.7% in high myopia cases). This relationship was statistically analyzed which was insignificant ((χ² = 1.72, p = 0.42). On comparison of patients with CI and without CI, the former showed considerably regressed NPC and lower PFV than the later one (p < 0.001). These outcomes suggests that in patients with myopia, CI being the most frequently present and hence it must be evaluated regularly during clinical examinations. Therefore, coexisting visual issues that are usually undiagnosed can be identified by integrating binocular vision assessment into standard myopia evaluations.
