www.PMID:23962101 nature.com/scientificreportsOPENNitric Oxide (NO) Mediates the Inhibition of Form-Deprivation Myopia by Atropine in ChicksBrittany J. Carr1 William K. StellMyopia is the most typical childhood refractive disorder. Atropine inhibits myopia progression, but its mechanism is unknown. Here, we show that myopia-prevention by atropine requires production of nitric oxide (NO). Form-deprivation myopia (FDM) was induced in week-old chicks by diffusers more than the appropriate eye (OD); the left eye (OS) remained ungoggled. On post-goggling days 1, three, and five, OD received intravitreally 20 of phosphate-buffered saline (vehicle), or automobile plus: NO source: L-arginine (L-Arg, 60,000 nmol) or sodium nitroprusside (SNP, ten,000 nmol); atropine (240 nmol); NO inhibitors: L-NIO or L-NMMA (6 nmol); negative controls: D-Arg (10 ol) or D-NMMA (six nmol); or atropine plus L-NIO, L-NMMA, or D-NMMA; OS received automobile. On day six post-goggling, refractive error, axial length, equatorial diameter, and wet weight we.
