Comparison of movable perimetry with non-movable perimetry among subjects with or without any eye disease

Not yet recruiting

• Conditions: Other glaucoma,

• Registration Number: CTRI/2023/09/057454
• Lead Sponsor: Dr Ramesh S Ve

Brief Summary

The research will be initiated after the approval from the Institution Research Committee (IRC) following the Institutional Ethics Committee (IEC) and then approval from the university. The participants will be recruited & written informed consent will be taken. They will then undergo routine eye examination (if they didn’t have any past one month) with the standard or the widely used measure for the detailed history taking, vision assessment, refraction, extraocular motility test, intraocular pressure measurement, anterior segment examination, posterior segment examination. An additional set of standard tests required to confirm the eligibility criteria for the normal subjects (if they didn’t have any past 1 month) is perimetry and for glaucoma & retinal subjects (if they didn’t have any past 1 month) are perimetry.

After this set of procedures, those who are fulfilling the eligibility criteria will be given an appointment based on his/her and the examiner’s feasibility.

In Phase I and Phase II, the patients will be recruited from the eye OPD only. Controls are the participants who will have no clinically significant retinal conditions like Glaucoma and Vascular retinopathies. Mainly patients who will be coming for the general eye examination for glasses one month after the cataract surgery will be included in the study.
