Current Research and Scholarly InterestsClinical Interest and Research
My primary areas of interest are in the diagnosis, medical and surgical treatment of vitreal retinal diseases. These principally include age-related macular degeneration and other diseases of the macula, and tractional syndromes, diabetic retinopathy, and complex forms of retinal detachment. I have been interested in the development of novel technology to diagnose and treat these diseases, including new forms of imaging, laser delivery systems, other microsurgical tools, and new drugs and drug delivery systems that inhibit new blood vessel growth, scarring and intraocular inflammation. I have been actively involved in translational research in the laboratory as well as technology transfer associated with that research for a variety of new therapies that have received FDA clearance and been introduced into clinical practice over the past 30 years.
