Visual Functions
The lab’s primary focus is evaluating advanced retinal function tests (colour vision, spatial and temporal contrast sensitivity, dark adaptometry and microperimetry) and designing novel retinal function tests that can act as a functional marker for early detection, quantify the severity of the disease, evaluate treatment outcomes, and provide insight into prognostic outcomes.
The overall objective is to quantify and understand the role of functional biomarkers in early detection and management strategies of retinal diseases and play a key role in preventing loss of vision. The research into visual functions becomes important when we realise that Visual acuity (VA)–the most measured outcome variable in randomized clinical trials to test the efficacy of drugs–is a poor marker of disease severity. VA has large test-retest variability and reflects only the central 1o of the retinal function.
Principle investigators
Amithavikram R Hathibelagal
Dr Hathibelagal is an Optometrist by training and his primary research interest is to study the visual-functional markers that help in early detection, progression and treatment outcomes of retinal diseases. He also has a keen interest in developing these markers.
He has several publications in peer-reviewed international vision science journals and is also a reviewer in many optometry/ophthalmology journals. He has also presented his research work at several national and international vision science conferences.
