Features of the Optic Disc Anatomy in Elderly Men

Abstract

Among the anomalies of the optic disc development, which change its anatomical characteristics, are the druses of the optic disc. Diagnostically, the druses of the optic disc are manifested by protrusion into the vitreous body, and changing in the area of the optic disc and its excavation. The aim of the study is to obtain new data on the optic disc anatomy in elderly men. Material and methods. The study was conducted in a group of men from 61 to 75 years old. The study included 53 eyes of patients treated with a disease of the visual organ unrelated to the pathology of the optic disc and macula. The study was carried out on the Optovue RTVue XR Avanti Sistem device using standard 3D Disc, GCC, ONH programs. Using optical coherence tomography the following morphometric parameters of the optic disc were evaluated: the volume of excavation, the thickness of the retinal nerve fiber layer, the area of the optic disc, the depth, the width and the area of the excavation of the optic disc in the horizontal plane. Conclusion. In the group of men from 61 to 75 years old, with increasing age, there is a decrease in the thickness of the retinal nerve fiber layer, the width of the excavation of the optic disc and the area of the optic disc. The shapes of optic disc excavation in elderly men are different, the triangular shape prevails – 47,8%, the remaining shapes occur with the same frequency.
