Retinal Map of Peripheral Retinal Degenerations and Tears. Part 2. Non-rhegmatogenous Chorioretinal Degenerations

Abstract

This part of the work describes the results of a multimodal examination of patients with non-rhegmatogenous chorioretinal peripheral degenerations.Objective: to conduct a multimodal study of the vitreoretinal interface of chorioretinal degenerations, to determine their place in the classification of peripheral degenerations to create an informative retinal map of peripheral retinal degenerations.Materials and methods. Patient examinations included traditional and additional ones: the ultrawide-angle fundus imaging with the Clarus 500 or VISUCAM 500 (Carl Zeiss Meditech Inc., Dublin, USA) and wide-field OCT Line scanning using the “sliding method” with SOLIX and RTVue XR Avanti (Optovue Inc. USA).Results. During the period of 2014-2024, 1304 peripheral degenerations and retinal tears were identified through the multimodal examination of 614 patients (959 eyes). Chorioretinal dystrophy was found in 134 patients: paving-stone degeneration — 75 (5.75 %), retinal drusen — 45 (3.45 %), Doyne honeycomb retinal dystrophy — 8 (0.61 %), retinal pigment epithelium hypertrophy (RPE) — 6 (0.46 %). Based on these studies, a clinical and topographic classification of peripheral degenerations and retinal tears is presented.Conclusion. In this article (part 2) we present studies of a group of nonrhegmatogenous chorioretinal degenerations with no changes in the vitreoretinal interface. The multimodal diagnostics of peripheral retinal degenerations have enabled the creation of a retinal map in order to systematize knowledge and improve treatment tactics.
