²M.D. Associate Professor, Mustafa Kemal University Faculty of Medicine, Department of Ophthalmology, Hatay/TURKEY Gyrate atrophy of the choroid and retina is an autosomal recessive chorioretinal dystrophy associated with separated chorioretinal atrophy areas in midperiphery retina and slowly progression. Gyrate atrophy causes hyperornithinemia secondary to the deficiency of ornithine aminotransferase activity. Low night vision, high myopia and peripheral visual field limitation are the earliest findings which occur in late childhood. The main aim in the treatment is to reduce plasma ornithine level. In the current study, we present a case of gyrate atrophy whose serum levels of ornithine decreased by vitamine B6 therapy and a diet with low protein.
