Aim: This study aims to study the types of visual field defects (VFDs) among the patients who underwent automated perimetry. Subjects and Methods: This study was the analysis of VFs of the patients who underwent VF recording on Octopus 900 perimeter (HAAG-STREIT, AG, Switzerland) at Shimla hills (IGMC, Himachal Pradesh, India) situated at the height of 7 200 feet above sea level. Results: Among the most common causes of VFDs in glaucoma (n = 119) the most common VFD was paracentral scotoma (44.4%) followed by arcuate scotoma (23.42%). The next common cause leading to VFD was nonocular neurological (n = 33) in which the most common VFD was quadrantanopia (27%) followed by bilateral temporal hemianopia (18%). Other ocular causes of VFD were cataract, age-related macular degeneration, central retinal vein occlusion, branch retinal vein occlusion, diabetic retinopathy (DR), anterior ischemic optic neuropathy, retinitis pigmentosa, and optic neuritis. Conclusion: This study concludes that the most of the patients for whom perimetry was performed on Octopus 900 perimeter under ocular conditions, the glaucoma was the most common disease. The second most common cause of VFD was neurological, the common lesions being head trauma, cerebrovascular accidents (CVA), and pituitary adenomas. Therefore, the stimulus for this work was not only ophthalmological but also neurological. Therefore, VF measurement is critical component in diagnosing not only glaucomatous VFD but also other nonocular and ocular blinding conditions.
