15 ex-vivo human retinas were obtained. The table contains information about the donor (sex, age, known medical history), surgery conditions (the ischemia duration, i.e. time without oxygen and nutrient supply, and whether a dark lens was put on the donor’s eye during surgery), and the retina (left/right eye, part of the retina without tumor). During preparation, the retina would sometimes roll up immediately after vitrectomy (rolling) or the vitreous was sticking strongly to the retina (sticky). The following two columns indicate how many retinal pieces were used per retina for the final analysis and whether any light responses were detected in our recordings. The last section indicates the number of cells responding to four types of stimuli (DG: drifting-grating); the last column shows the number of cells responding to any of the four stimuli. Light gray rows: retinas with few light responses, not used for analysis. Dark gray rows: no detectable light responses. Bold: potential reasons for low quality. Ventr./v = ventral, dors./d = dorsal, temp./t = temporal, n = nasal, m = male, f = female, radiation = radiation of the tumor-bearing eye, detachment = partial retinal detachment prior to surgery, resp. = responses. *retina prepared by another group during a different study.
