Abstract
PURPOSE: To perform a detailed individual analysis of pathological parameters of the optic disc, peripapillary retina and macular ganglion cell complex in eyes with the disc area of 1.63–2.43 mm2 and different stages of glaucoma.
MATERIALS AND METHODS: The study included 64 patients (76 eyes) aged 63.3±8.7 years, among them 35 male and 29 female patients with stage I (35 eyes), stage II (21 eyes) and stage III (20 eyes) glaucoma. Tomographic parameters of the retina were measured with optical coherence tomography (OCT) and Heidelberg laser retinal tomography (HRT) using a modified program by V.A. Machekhin, with consideration of the individual disc size, regression analysis and color coding of pathological parameters of the optic disc and peripapillary retina.
RESULTS: Pathologically similar parameters that showed different relations between the tomographic results were divided into 3 subgroups: a) with equivalent results according to both methods; b) with the advantage of HRT method; c) with the advantage of OCT method.
CONCLUSIONS: Examination of the optic disc parameters and adjacent retina using both HRT and OCT methods complementing each other can help improve the understanding of the glaucomatous processes.
