Aim: To study visual field changes in patients with raised intraocular pressure and optic disc changes suspicious of glaucoma. Methodology: This was a cross sectional studies of 100 patients with disc changes suspicious of glaucoma or IOP≥21 mm Hg were included. Patients of both sexes and all age groups were included. Anterior chamber angle was examined with Goldmann 3 mirror gonioscopic lens. IOP was measured with applanation tonometer. Fundus examination was performed to document the degree of optic disc cupping. Results: The prevalence of visual field defects in the present study was 36%. 36 patients showed glaucomatous field defects. Mean age of patients with field defect was 48 years ± 10.6. Majority of patients with field defects were above 50 years of age, only 20% of patients had a positive family history of POAG .The mean IOP of 51 eyes with visual field defects was found to be 28.02 ± 7.65 mm Hg.50% of patients with asymmetrical C:D ratio ≥ 0.2 had visual field defects. Conclusions: Glaucoma suspects patients with F/H/O glaucoma, IOP ≥ 21 mm Hg, C:D> 0.5 & a symmetrical cupping are more prone for glaucoma& also constitute an important group that would benefit from energetic screening for glaucoma by Visual field analysis.
