Purpose: To evaluate the duration-dependent and synergetic impact of high-intensity light (HL) unrestricted vision (UnV) on lens-induced myopia (LIM) development in chickens. Methods: Myopia was induced one eye chicks (10 groups, n = 126) from day 1 posthatching (D1) until 8 (D8) using –10 diopter (D) lenses. Fellow eyes remained uncovered as controls. Nine groups were exposed daily to 2, 4, or 6 hours HL (15,000 lux), UnV (removal D lens), both (HL + UnV). One group served LIM without any...

PURPOSE. To estimate the normal value of macular pigment optical density (MPOD) in an adult south Indian sample. METHODS. Three hundred eyes 161 healthy volunteers (30 men and 30 women each age groups 20-29, 30-39, 40-49, 50-59, ≥60 years) underwent MPOD measurement with a densitometer. Thirty-two were also checked for intersession variability. RESULTS. The mean MPODs sample 0.64 ± 0.23 log unit at 0.25° eccentricity, 0.50 0.21 0.5°, 0.37 0.19 1.00°, 0.16 1.75°.
