Macular telangiectasia Type 2 (MacTel 2) is a bilateral disease characterized by neurodegenerative and vascular changes around the fovea. Degeneration of Müller cells is believed to be the underlying cause. In eyes with MacTel 2, the ellipsoid zone disruption initially occurs in temporal the parafoveal area and progresses in time. The acircularity index has strong negative correlation with EZ-RPE thickness and EZ-RPE volume.
