So I think we really need to think long and hard , you know , about the future strategies for blood supply ; and I think it 's going to become very critical . Intrauterine and submucous fibroids cause distortion of the cavity ; compromise the blood supply ; and are responsible for a lack of embryo implantation , early miscarriages , premature delivery , and abruptio placentae . Goal : To investigate how the normal retina develops ; how it changes with aging ; what are the consequences of insults to the retina , retinal pigment epithelium , and blood supply ; and what are the possible rescue and repair mechanisms .
