Whole eye transplantation (WET) provides individuals
with irreversible vision loss the opportunity to receive
an intact visual system. A viable ocular environment
that stimulates adequate blood circulation and
reconstructs axonal integrity is essential in the
restoration of visual function. The purpose of this
study is to demonstrate the viability of our WET model
to assess aqueous humor dynamics and tissue permeability
of the transplanted eye using gadolinium (Gd)-enhanced
MRI. In addition, diffusion tensor imaging was employed
to determine the structural integrity of the optic nerve
following WET.
