Histological evidence for revascularisation of an autologous retinal pigment epithelium--choroid graft in the pig.

Background: Translocation of a free autologous graft consisting of retinal pigment epithelium (RPE), Bruch's membrane, choriocapillaris and choroid in patients with exudative age-related macular degeneration is currently being evaluated in clinical practice. Angiographic studies in these patients suggest that their grafts become revascularised.

Aim: To investigate the histological evidence of revascularisation of the graft in a porcine model.
