title: Discordant refraction in male monozygotic twins.
abstract: As part of the Genes In Myopia (GEM) Study, the authors describe a pair of monozygotic twins who presented with discordant hypermetropia. Both twins also reported amblyopia, but the cause differed. The phenomenon of refractive discordance in twins is rare, with this case representing only the second to ever be reported.
