The myopia research laboratory was established at the L V Prasad Eye Institute, Hyderabad in the year 2017. Research at the myopia lab involves both basic and applied aspects of myopia mainly investigating epidemiology, pathogenesis/causation of myopia/pathologic myopia to eventually develop a cost-effective anti-myopia strategy that can be used worldwide for myopia control. The multifactorial influence on myopia causation, the complex gene-environment interactions makes it difficult to draw concrete conclusions in myopia research through cross-sectional studies. The research in this lab focuses on investigating the temporal development of signs (both in the centre and periphery of the eye) to identify novel optical and imaging markers for myopia/high myopia/pathologic myopia via longitudinal and short-term defocus studies.
