In the News
Glaucoma — a group of eye conditions that damage the optic nerve and can result in vision loss and blindness — affects more than 200,000 Americans each year. There is no cure, but early detection and treatment can often protect against serious vision loss. An, a board-certified ophthalmologist and fellowship-trained glaucoma specialist, works to help patients affected by glaucoma.
A skilled eye surgeon, An performs procedures to treat the disease — including micro-invasive glaucoma surgery (MIGS). Previously, patients with mild-to-moderate glaucoma had limited options; MIGS is creating a new avenue for treatment for these individuals. An also conducts research to advance glaucoma treatment, including modulation of post-operative wound healing and improved long-term surgical outcomes. In 2015, she completed a Clinical Fellowship in Glaucoma and Advanced Anterior Segment Surgery (used to treat glaucoma and complex cataracts) at the University of Toronto.
In addition to glaucoma procedures, An performs both simple and complex cataract surgery and treats patients as a clinician at MU’s Mason Eye Institute. For her excellence in the clinic and the laboratory, she has won multiple recognitions including the Young Clinician Scientist Award from the American Glaucoma Society.
Dr. Jella An is medical director of University Eye Institute East and directs the Glaucoma Service and Fellowship Program at the School of Medicine.
