Comparative analysis of several morphometric parameters received using optic coherent tomography and scanning laser ophthalmoscopy in initial glaucoma diagnosis

: Retinal morphometric parameters received using confocal scanning laser ophthalmoscopy and optic coherent tomography (OCT) are compared. OCT was performed using Stratus OCT 3000 ("Carl Zeiss Meditec"), and for confocal scanning laser ophthalmoscopy we used Heidelberg retinal tomography HRT 3.0 ("Heidelberg Engineering"). A total of 81 patients (158 eyes) were enrolled into the study: 34 patients (64 eyes) with suspected glaucoma (diagnosis of early open angle glaucoma was proven after ophthalmologic examination) and 47 healthy adults aged from 38 till 72 years old. OCT was found to reveal significant decrease of retinal nerve fiber layer (RNFL) thickness in peripapillary zone in patients with suspected glaucoma as compared with healthy subjects, whereas no significant difference in morphometry of neuroretinal rim and PNFL was found using confocal scanning laser ophthalmoscopy (HRT).
