Clinical Research

The South Texas Retina Consultants’ Clinical Research Department was created in early 2006 to further the advancement of retina research. Dr. Charles Campbell has always believed in utilizing cutting edge treatment and surgical technology to preserve the vision of individuals with potential visual loss in South Texas. Dr. Campbell feels that to further the advancement of retina research it is important that the unique pathologies common in South Texas are represented in the studies. An additional benefit to the research for South Texas Retina Consultants’ patients is that the studies bring the cutting edge treatments and surgical techniques to individuals without regard for their ability to pay.
