Eligibility
Inclusion criteria
Inclusion criteria: 1. Age more than 18 years 2. Both genders 3. Disease Condition: Glaucoma suspects. Glaucoma suspects were defined as those with ANY ONE OR MORE of the following features: -Individuals with elevated intraocular pressure , that is, beyond 21mmHg. -Individuals with manifest optic disc changes, such as Optic Disc Cupping, Neuroretinal Rim Thinning, or Loss. or retinal nerve fiber layer abnormalities, as seen by standard of care testing. -Individuals with risk factors such as strong positive family history of glaucoma
Exclusion criteria
Exclusion criteria: 1. Individuals with unreliable visual field testing results. 2. Those with a best corrected visual acuity worse than 6 by 18. 3. Those not capable of sitting upright. 4. Those with other ocular diseases affecting visual fields, such as retinal detachment, central vein occlusion, diabetic retinopathy or other neuropathies unrelated to the study condition. 5. History of intraocular surgery, other than uncomplicated cataract or glaucoma surgery.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| -Sensitivity and Specificity of Nasal Step Threshold Test and 24-2 testing in the diagnosis of Glaucoma among Glaucoma suspectsTimepoint: Across follow up as advised for glaucoma screening, such as at 3 months, 6 months and 1 year across follow up visits. | — |
Secondary
| Measure | Time frame |
|---|---|
| -Comparison of nature & absolute number of VF changes (eg step defects) picked up by the two tests -Descriptive analysis of field changes in both, which can be quantified as a set of testing criteria for Nasal step defects as seen in BOTH 24-2 AND NSTT -Comparison of time taken for both.Timepoint: Across follow up as advised for glaucoma screening, such as at 3 months, 6 months & 1 year across follow up visits. | — |
