Macular associations of tilted disc syndrome

Abstract

Purpose: The aim of this study was to describe macular changes associated with tilted disc syndrome (TDS) using multimodality imaging. Methods: This is a retrospective observational study of the consecutive TDS cases which were studied for macular changes using color fundus photographs and optical coherence tomography (OCT). Fundus autofluorescence, fundus fluorescein angiography, and OCT angiography were performed wherever required. Results: Twenty consecutive TDS cases (36 eyes) were included. OCT showed inferior depression of all layers in specific scans and macular pathologies seen included lamellar macular hole, full-thickness macular hole, retinal pigment epithelial detachment, acute and resolved subretinal fluid, central serous chorioretinopathy, and choroidal neovascular membrane. Macular involvement was seen in 13 eyes (36.11%) while in the remaining 23 eyes, outer retinal changes were seen on OCT in 9 eyes and normal retinal layers in 14 eyes (38.89%). Conclusion: Various macular pathologies associated with TDS are described using multimodality imaging. These provide understanding of changes which can occur with TDS. It also highlights the need for recognition, differentiation from similar confusing entities, and the necessity to follow-up of these cases carefully to detect the macular changes earlier.
