Retina Physicians

Retina/Vitreous
Doheny's Retina/Vitreous Service consists of comprehensive consultative, medical and surgical care. The group specializes in the repair of complex retinal detachments, offering advanced techniques such as silicone oil, perfluorocarbon liquids and SF6 and C3F8 gases. The group is particularly well equipped to repair penetrating trauma, drawing from its members' vast surgical and research experience. Laser treatment of the retina for diabetic retinopathy can be performed with the argon, krypton, diode, or double frequency YAG laser. Extensive diagnostic services are available through our ancillary services departments.

Doheny faculty members are leading researchers in retinal transplantation, imaging of ocular disease and age-related macular degeneration.

	Rizwan Bhatti, MD Clinical Specialties Medical and surgical areas of retina vitreous with special interests in age-related macular degeneration, diabetic retinopathy and complex retinal detachments. Dr. Bhatti is a co-investigator in a number of clinical trials for macular degeneration, diabetic retinopathy, and retinal vascular diseases. He is currently the Director of the Doheny Eye Center in the Coachella Valley in Southern California. Academic Degrees Medical College of Ohio, Toledo, OH Residency Henry For Hospital Deprtment of Ophthalmology Chief Resident, July 2004-June 2005 Fellowships Doheny Retina Institute, University of Southern California, Doheny Eye Institute Vitreo-Retinal Surgical Fellowship Board Certification American Board of Ophthalmology Research Activities Dr. Bhatti serves as an investigator in the Doheny Image Reading Center. In addition, he is studying different surgical instrumentation for vitreous surgery with a special interest in the endoscopic evaluation of surgical sclerotomies.

	Lawrence Chong, MD Dr. Chong earned a M.D. from Harvard University. He completed his residency at Doheny Eye Institute, University of Southern California, and his retina-vitreous fellowship at the Duke University Eye Center. He returned to the Doheny Eye Institute as chief resident before joining the faculty. His research interests include AIDS retinopathy, macular degeneration, retinal pigment epithelial selective lasers and dye enhanced laser treatment of ocular tumors. Dr. Chong's research in the sustained release of ganciclovir for CMV retinitis represents a breakthrough in AIDS research since it involves implantation of a device into the eye to allow for the slow release of drugs over an extended period of time. This benefits those patients who cannot tolerate systemic, intravenous drugs.Dr. Chong is Chief of the Retina Service at the Doheny Eye Institute and Associate Professor of Ophthalmology at the USC Keck School of Medicine.

	Mark Humayun, MD, PhD Dr. Humayun completed his medical degree at Duke University Medical School. While in his residency training at Duke Eye Center, Dr. Humayun earned his Ph.D. in Biomedical Engineering at the University of North Carolina at Chapel Hill. He completed his fellowship training in vitreoretinal disease at the Wilmer Ophthalmological Institute at Johns Hopkins. Dr. Humayun served most recently at the Wilmer Ophthalmological Institute at Johns Hopkins as an Associate Professor and as Director of the Intraocular Retinal Prosthesis Lab. The focus of this lab is to develop a retinal implant for the blind. He has had a close working relationship with Biomedical Engineering and a number of national labs such as Naval Research Laboratory and Oakridge National Laboratory.

	Linda Lam, MD Dr. Lam attended medical school at Cornell University Medical College. During medical school, she completed a one year research fellowship investigating the protein sorting pathways in retinal pigment epithelium cells. Dr. Lam further pursued her interest in retinal research during her ophthalmology residency at Cole Eye Institute at the Cleveland Clinic Foundation. Dr. Lam then completed a two-year combined fellowship program in vitreoretinal diseases and surgery at Georgetown University Hospital, Washington Hospital Center, and Retina Group of Washington. An area of particular interest is mechanisms of retinal physiology and degeneration. Dr. Lam's primary clinical research interests are developing treatments for macular degeneration, as well as exploring both medical and surgical modalities for the treatment of diabetic retinopathy and proliferative vitreoretinopathy. Dr. Lam serves as the Medical Director at the Doheny Retina Center in Riverside.
