Abstract
Phagosomes containing membranous debris were found in the choroidal endothelium of rabbits following periods of acute pressure ischaemia and also accompanying periods of post-ischaemic recovery. The membranous debris may be of visual cell origin and pass into the choroid by a transpigment epithelial route. Ischaemia may be a sufficient stimulus to induce the vascular endothelium to engulf this material. The phagosomes were found only in ischaemic or post-ischaemic tissue.
