Intraretinal changes in MacTel are predominantly empty spaces in the foveal and perifoveal region. We describe and assess these lesions by 3D optical coherence tomography reconstruction.
4 eyes (2 patients) with MacTel were imaged using SS-OCT (Topcon DRI SSOCT-1 Atlantis) system to obtain volumetric images of the macula (6x6mm, 256 images). A prototype denoising analysis software was applied and compartmentalization and quantification with 3D reconstruction of intraretinal empty space was performed by semi-automatic segmentation of speckle-noise freed OCT volumes.
4 eyes of 2 male MacTel patients were investigated. Mean volume 15'837.8 (range 6206-29'230) and mean surface of the empty spaces was 4891.9 (range 3411-9578), respectively. A 3D reconstruction of the lesion was assessed.
Speckle-noise freed OCT may serve as a new illustrative imaging technology. It can be used for compartmentalization and quantification intraretinal lesions such as empty spaces in MacTel.
