Preservation of the Photoreceptor Inner/Outer Segment Junction in Dry Age-Related Macular Degeneration Treated by Rheohemapheresis

Figure 2

(a) SD-OCT of the left eye of a patient with the dry form of AMD before initiation of rheohemapheresis treatment. A large photoreceptor IS/OS junction defect marked by arrows at its beginning and end. Only the top of the surface DPED under the central foveola shows remnants of previous photoreceptor IS/OS junction detachment (indicated by arrowheads) in the form of degraded degenerated material of the original junction. The photoreceptor IS/OS junction is normally attached to the RPE only peripherally from the arrows. Visual acuity at this stage was 20/80 (0.25). (b) Multifocal electroretinography. Superposition of mfERG responses to the fundus of the left eye of the patient from (a). (c) A three-dimensional image of the electrical activity of the retina. Left: A three-dimensional image of the electrical activity of the retina of the left eye of the patient from (a) and (b) compared to the normal-for-age image on the right (decrease of foveal and parafoveal responses below the normal range, i.e., grey-colored central depressions bordered by green, i.e., within normal range responses).
