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.

	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.
