Research Abstract

We have been involved in studying the neurosensory retina and retinal pigment epithelium in order to develop treatments for macular diseases such as age-related macular degeneration and myopic neovascular maculopathy, both diseases that have been increasing recently due to the "graying" of society. Specifically, our research has involved (1) developing an experimental model for wound healing of the retinal pigment epithelium, (2) examining wound healing in clinical cases where retinal pigment epithelial cell defects have occured, and (3) examining the feasibility and efficacy of foveal translocation surgery in patients. We examined the effect of growth factors as well as changes that occur in expression of extracellular matrix proteins during wound healing in rat retinal pigment epithelium sheet cultures after trephination to form a round wound. Clinically, scanning laser ophthalmoscopy (SLO) was used to evaluate changes after surgical removal of choroidal neovascularization, showing that damage occurs to the retina, the retinal pigment epithelium as well as the choriocapillaris. Based on such studies, we have come to the conclusion that, at present, foveal translocation surgery represents the best available treatment for neovascular maculopathy. We have previously shown that after foveal translocation via focal retinotomy, visual acuity can improve to 20i20. In addition, the majority of patients after foveal translocation via scleral shortening obtained improvement in visual acuity. We have also shown that SLO and optical coherence tomography are useful in evaluating foveal function postoperatively. Currently, we believe that foveal translocation via scleral shortening may be appropriate for relatively small choroidal neovascular membranes and for myopic neovascular maculpathy, while foveal translocation via 360 degree retinotomy may be appropriate for foveal translocation in age-related macular degeneration.
