Dogan B, et al. - In this study, the authors analyzed 40 eyes with macular telangiectasia type 2 (MacTel 2) and 36 eyes in the control group to estimate the retinal and choroidal vascular alterations through optical coherence tomography angiography (OCTA) in MacTel 2 cases. They performed fundus color photographs, fundus autofluorescence, fundus fluorescein angiography, spectral-domain optical coherence tomography, and OCTA. They observed a positive association between retinal whole, parafoveal temporal quadrant vascular density of the superficial and deep plexus and ganglion cell-inner plexiform layer (GCIPL) thickness in MacTel 2 cases. They found retinal vascular density and foveal avascular zone (FAZ) changes in MacTel 2 in the deep capillary plexus of the retina.
