ABSTRACT
Background & Objectives: Myopia or short-sightedness is a type of refractive error. Myopia can be classified by aetiology and by its clinical presentation. Here, the aim of this study was to observe changes occurring in the posterior segment of eye - vitreous, choroid & retina in high myopic patients and also to evaluate any correlation between the degree of myopia, axial length and the visual acuity.
Methodology: A hospital-based study was conducted on 150 patients between March 2016 to March 2017. A detail demographic data, ocular history and family history was collected from patients. Ocular examination was carried out by different ocular tests. Statistical analysis was performed by using JMP Pro version 12.0.1 & Shapiro-Wilk Goodness of Fit test.
Results: Majority of cases of myopia were observed in the age group of the third decade. Highly myopic patients showed a high incidence of optic disc tilt (65%), peripapillary atrophy (72%), and retinal tessellation (65%). Study results also showed that the severity of myopia is correlated with axial length & visual acuity.
Conclusion: Study findings revealed that there is a strong correlation existed between the presence of parapapillary atrophy and high myopia. There was also a strong positive correlation between axial length and visual acuity.
