Abstract :

Field of vision reflects status of retinal functioning. Factor affecting the integrity of retina may also alter normal field of vision. Myopia, being one of such condition estigates us to design this study. This study was carried out on thirty emmetropic and thirty myopic subjects of equal number of both sexes of 22–30 years of age. After routine ophthalmic examination, automated perimetry was done with the help of “ Humphrey Visual Field Analyzer” and results were evaluated in terms of three global indices namely Foveal Intensity (FI), Mean Deviation (MD) and Pattern Standard Deviation (PSD) representing the retinal sensitivity. FI and MD were statistically significantly lower in myopes than emmetropes and PSD was statistically significantly higher in myopes than emmetropes. In view of these findings, early detection of visual field loss due to myopic refractive error helps for better diagnostics and prompt management.
