Jaisankar D, et al. - Researchers attempted to contemplate the variations in foveal and parafoveal thickness, estimated via optical coherence tomography across five stages of macular telangiectasia 2 (MacTel 2). Furthermore, they resolved to associate the foveal slope angle with best-corrected visual acuity (BCVA). A better connection was noted between BCVA with slope angles than central retinal thickness. This, in turn, implied that the variation in both foveal and parafoveal regions accounted for vision change. It was also reported that greater the foveal slope angle, the better the vision.
