Retina and optic nerve characteristics in fellow eyes of patients with epiretinal fibrosis after retinal detachment

The purpose of the study was to examine the relation between the state of macular area and optic disc in fellow eyes of patients after rhegmatogenous retinal detachment (RRD) and the development of epiretinal fibrosis in association with silicone tamponade. Material and Methods. The study included 18 patients operated on for RRD using vitreous cavity tamponade by silicone oil. The examination was performed by means of optical coherence tomography-angiography for fellow eyes of patients. Results. Analysis of retinal thickness and volume revealed that the indices were lower in the group with epiretinal fibrosis. When assessing relative vascular density, area and perimeter of foveal avascular zone (FAZ) the indices were prevailed in the group with epiretinal fibrosis. Conclusion. The study revealed a significant decrease in retinal thickness in the fovea of fellow eyes in patients with epiretinal macular fibrosis. A statistically significant decrease in the thickness of the reticular membranes is revealed in patients with epiretinal macular fibrosis. A statistically significant enlargement of the area and an increase in the perimeter of FAZ, an increase in the relative vascular density in the foveal and deep plexuses in the fellow eyes of patients with epiretinal macular fibrosis were revealed as well.
