Philosophy of Care

I strongly believe in patient education, and work with patients together as a team to develop their treatment plans. I encourage my patients to ask questions, and take the time to carefully explain their condition to them.

By helping each patient understand the nature of their eye disease, and also providing up-to-date information about clinical trials and retina research, I strive to help them make informed decisions about their eye care.

I strive to provide compassionate care to all my patients, and enjoy developing a long-term relationship of mutual trust and respect with each individual that I see.

Clinical Interests

Dr. Yiu is a vitreoretinal specialist at the UC Davis Eye Center. He received his medical training at Harvard Medical School, where his graduate research explored molecular mechanisms of nervous system regeneration and earned him a dual MD-PhD degree. After residency at the Massachusetts Eye & Ear Infirmary, he underwent fellowship training in vitreoretinal surgery at Duke University, where he was also involved in advanced ocular imaging research to study mechanisms of age-related macular degeneration and diabetic retinopathy. 

As a vitreoretinal specialist and surgeon at UC Davis, he specializes in both the medical and surgical management of various retinal diseases, including macular degeneration, diabetic retinopathy, retinal vascular conditions, retinal detachments, retinal degenerations, and macular diseases such as epiretinal membranes and macular holes.

Research/Academic Interests

Dr. Yiu is involved in translational research to study the pathogenesis and develop therapies for age-related macular degeneration, and other retinal diseases. His focuses include ocular imaging technologies, gene editing, drug delivery, and primate models of retinal disease. He presented the first use of CRISPR-based genome editing as a treatment strategy for wet macular degeneration, and pioneered work to study macular degeneration features in rhesus monkeys. 

His translational research program spans animal models from mice to non-human primates to human patients, and he is actively involved in recruitment for major clinical trials for new treatments. He has published numerous peer-reviewed scientific papers and book chapters, and has given lectures nationally and internationally. He is the editor of the textbook "Vitreoretinal Disorders", serves as editor and reviewer for several academic journals, and is a course lecturer at the American Academy of Ophthalmology.

Dr. Yiu has also been the recipient of numerous prestigious award including the Ronald G. Michels Foundation Fellowship Award, the Heed Ophthalmic Foundation Fellowship Award, the Retina Society Fellowship Research Award, and the Macula Society Evangelos S. Gragoudas Award. In 2016, he was named as one of 21 "Emerging Vision Scientists" by the National Alliance for Eye and Vision Research for his cutting edge research.
