Dr. Liu is the only pediatric neuro-ophthalmologist at The Children's Hospital of Philadelphia. His practice bridges the fields of ophthalmology and neurology through diagnosis and management of patients with neurological disorders that affect vision and eye movements. Dr. Liu also treats patients with poorly-defined visual symptoms, many of which remain unresolved despite previous ophthalmic and neurologic evaluations. Dr. Liu's patients seek evaluation and treatment for:
- Double vision
- Optic neuritis and other optic nerve problems
- Pupillary abnormalities
- Unexplained vision loss
- Visual field defects
- Migraine and related visual complaints
- Optic disc swelling
- Abnormal eye movements (ophthalmoparesis or nystagmus)
- Intracranial lesions affecting the visual pathway
Dr. Liu received his medical degree from the Columbia University College of Physicians and Surgeons in 1988. He completed a medical internship at Columbia Presbyterian Hospital from 1988-1989, and a neurology residency at the Harvard-Longwood Neurology Program (Children's Hospital, Brigham and Women's Hospital, Beth Israel, and Brockton-Westbury VA Hospitals in Boston, Mass.) from 1989-1992. He then completed a neuro-ophthalmology fellowship at the Bascom Palmer Eye Institute in Miami, Fla. from 1992-1993.
Dr. Liu began practicing neuro-ophthalmology at the University of Pennsylvania and The Children's Hospital of Philadelphia in 1993. He was the first on-site neuro-ophthalmologist The Children's Hospital of Philadelphia. Currently there are more than 2000 pediatric neuro-ophthalmic visits per year.
Philadelphia Magazine has named Dr. Liu a "Top Doc" in neuro-ophthalmology every year since 2001.
Dr. Liu is currently a Professor of Neurology and Ophthalmology at the University Pennsylvania. He is considered an international expert on pediatric neuro-ophthalmic topics such as pediatric pseudotumor cerebri, vision testing in children with neurofibromatosis and optic pathway gliomas, and pediatric optic nerve disorders.
He was awarded one of Penn's 2013-14 Christian R. and Mary F. Lindback Awards for Distinguished Teaching
Dr. Liu is a member of the University of Pennsylvania's Division of Neuro-ophthalmology in the Departments of Neurology and Ophthalmology. With three full-time faculty members and active clinical and research components, it is one of the largest neuro-ophthalmology groups in the country. Dr. Liu co-authored the textbook, Neuro-ophthalmology: Diagnosis and Management (2nd edition, Elsevier, 2010); a reviewer in the New England Journal of Medicine called the first edition "probably the best-illustrated, most comprehensive single-volume textbook on neuro-ophthalmology available today." The release of the third edition is planned for 2016.
