Abstract

Purpose: To measure the contrast sensitivity in different types of glaucoma patients.

Material and Method: An observational and non-probability convenient sampling study from February to August 2020, using lea contrast sensitivity, Snellen visual acuity charts, trial box and occlude.

Result: Out of 60 patients 37 were males and 23 were females. Mean onset age was 38.4 years between 16-80 years. 33 (55%) patients were diagnosed with Primary Open Angle Glaucoma, 17 (28.3%) patients with Primary Close Angle Glaucoma, 7 (11.7%) patients with Acute Closure Glaucoma and 3 (5%) patients with Secondary Glaucoma. Similar with Glasses 46 (76.7%) patients had visual acuity 6/6 to 6/12, 11 (81.3%) patients had 6/18 to 6/36 and 3 (5%) patients had 6/60. According to contrast sensitivity 30 (50%) patients had 1.25% (80%), 21 had 2.50% (40%) and 9 had 5% (20%). 15 subjects had 1.25% (80%), 13 subjects had 2.5% (40%) and 5 subjects had 5% contrast sensitivity in POAG. 11 subjects had 1.25% (80%), 4 subjects had 2.5% (40%) and 2 subjects had 5% contrast sensitivity in PCAG. 3 subjects had 1.25% (80%). 3 subjects had 2.5% (40) and 2 subjects had 5% contrast sensitivity in ACG.

Conclusion: There is reduction in contrast visual acuity with and without refraction most of patients had variation at level of Contrast Visual Acuity in Primary Open Angle Glaucoma.
