Study Overview
Brief Summary
Protocol Summary:
The purpose of our study is to compare the Elisar Supra threshold algorithm with the Humphrey‘s screening algorithm.
Description of study device:
Elisar Visual Field Analyzer (EVFA) is the Virtual Reality (VR) based perimeter.
Study design: A cross sectional study.
Inclusion criteria:
Controls:
1. The best corrected visual acuity should be 6/6 for age <55 years and 6/9 or better for age >55 years.
2. Spherical correction should be < 5 D, Cylindrical correction should be < 3 D.
Glaucoma:
1. Glaucoma is defined as IOP greater than 21 mmHg or intraocular difference in IOP more than 3mmHg and Cup disc ratio more than 0.5, and the intraocular difference in cup disc ratio less than more than 0.2.
2. A positive report of the screening test with Humphrey visual field analyzer.
Exclusion criteria:
1. Fixation losses , false positive and false negative > 20% will be excluded from the study.
2. The reports with significant lid artifact will be excluded from the study.
