- Department of Ophthalmology
Quan V. Donny Hoang, M.D., Ph.D. is a nationally recognized physician and researcher specializing in the treatment of retinal disorders.
Dr. Hoang went to Northwestern University where he received a triple major with honors in Chemistry, Biology and Integrated Science. He then received his joint M.D. and Ph.D. in Neuroscience from the University of Illinois at Chicago where he was awarded the 2005 Grass Fellowship at the Marine Biological Laboratory and the 2006 Top Thesis award in the Life Sciences before completing his residency at the University of Illinois Eye and Ear Infirmary under Drs. William Mieler and Dmitri Azar. Dr. Hoang completed in fellowship in vitreo-retinal surgery at Columbia University Medical Center and the Vitreous, Retina, Macula Consultants of New York (VRMNY) under the joint direction of Dr. Stanley Chang and Dr. Lawrence Yannuzzi.
Dr. Hoang is a well-published physician scientist with over 20 first-authored peer-reviewed articles and over 30 abstracts. His current research projects focus on pathologic myopia, specifically clinical studies employing multimodal imaging to better assess myopic staphyloma progression as well as pre-clinical studies utilizing scleral collagen crosslinking as a novel therapeutic intervention.

Education & Training
The Hoang laboratory implements a translational research program consisting of:
- identifying the type of patients with extreme near-sightedness (pathologic myopia) that are at the greatest risk of permanent vision loss,
- discovering novel treatments to stunt myopia progression to avoid the vision-threatening changes, and eventually
- applying these novel treatments to at-risk patients.
Pathologic myopia, or extreme nearsightedness, is a leading cause of blindness and health disparity worldwide. It has been estimated that up to 2.3 billion people are myopic globally and the numbers are rising. Presently, myopia affects at least 33 percent of adults in the United States and as high as 80 percent in Southeast Asia. Although minimal levels of near-sightedness are considered a minor inconvenience, high (pathologic) myopia can lead to irreversible vision loss. Myopia is often due to excessive eye elongation. Pathologic myopia occurs at extreme levels of lifelong, progressive eye elongation and subsequent eye wall (sclera) thinning, which allows for localized outpouchings (called staphyloma). It is a breakdown in the structural integrity of the collagen component in the eye wall that may underlie myopic progression and precede irreversible vision loss.
The first step in identifying pathologic myopia patients at greatest risk of vision loss is to perform multimodal imaging and in vivo biomechanical testing to establish a quantitative measure of the stiffness of the posterior eye wall. This goal is achieved by a combination of imaging modalities such as optical coherence tomography, ultrasonongraphy and magnetic resonance imaging with the eye at rest as well as during biomechanical stress-strain experiments.
Concurrently, novel therapeutic approaches are explored in preclinical studies in animal models where non-light-activated chemicals are applied in vivo to crosslink the collagen in eye walls to act as a mortar, stiffening the wall and stunting eye elongation (and progression of nearsightedness). These two approaches together will arrive at an in vivo quantitative measure to identify the type of pathologic myopia patients that would most benefit from our novel treatment, once animal trials are completed.
