Intrasurgical imaging of subinternal limiting membrane blood diffusion in terson syndrome.

We report a case of Terson syndrome, providing the first intrasurgical imaging of subinternal limiting membrane blood diffusion in Terson syndrome. We highlight some remarkable in vivo anatomical findings that may give a contribution to the debate about its pathogenesis. Here we hypothesize that the subretinal space might be unlikely to be a primary source of intraocular hemorrhage, and we support the two generally accepted theories about blood diffusion from the retinal vasculature or from the perivascular spaces.
