Multimodal imaging and genetic screening in Mexican patients with Gyrate atrophy: identification of novel OAT pathogenic variants.

Purpose: Description of retinal phenotype by structural and functional testing, ornithine plasma levels and mutational data of OAT gene in patients with Gyrate Atrophy (GA).

Methods: Ophthalmologic examination, fundus photography (CFP), autofluorescence (FAF), spectral-domain optical coherence tomography (SD-OCT), Goldmann perimetry (GP), full-field electroretinogram (ffERG) and chromatic perimetry (CP) testing were performed. Ornithine plasma levels were measured.
