School of Optometry and Vision Science

Srinivas Marmamula received his initial optometry training at L V Prasad Eye Institute and then did his Masters in Community Eye Health from the London School of Hygiene and Tropical Medicine, University of London, with joint sponsorship from the Department for International Development (DFID - UK), British Council for Prevention of Blindness (Boulter Award), and LVPEI. In 2011, he completed his PhD from the School of Optometry and Vision Science, UNSW, Sydney with support from Vision CRC, Australia. Dr Marmamula did his post-doctoral research fellowship during 2012-2013 with Dr David Friedman at Wilmer Eye Institute, Johns Hopkins School of Medicine, Johns Hopkins University, Baltimore, MD, USA. He was also trained briefly in Massachusetts Eye and Ear at Harvard Medical School’s Department of Ophthalmology in Boston, USA (2019). Dr Marmamula was the chief optometrist for LVPEI’s landmark studies including Andhra Pradesh Eye Disease Study I (APEDS I, 1996 – 2000), Refractive Error Study in Children (2000) supported by the National Eye Institute and World Health Organization and APEDS III. He is the principal investigator for ‘The Hyderabad Ocular Morbidity in Elderly Study (HOMES)’ (2017-2020). He is also a faculty member at Brien Holden School of Optometry and Vision Science.

Dr Marmamula is the recipient of the prestigious Wellcome Trust / DBT India Alliance Early Career Fellowship - 2015. This is for a research project on visual impairment in elderly populations. He has also received many international travel grants and has participated as faculty in many workshops in India and abroad. He has over 100 publications to his credit in peer-reviewed journals and is on the editorial board of reputed journals.

Dr Marmamula was recently awarded a Wellcome Trust / DBT India Alliance Intermediate to conduct a longitudinal research study on elderly populations. His areas of interest are epidemiology of visual impairment, uncorrected refractive errors, presbyopia, eye health in the elderly and other vulnerable populations and training personnel for community eye care.
