Grant T. Liu, MD, is a pediatric neuro-ophthalmologist at Children’s Hospital of Philadelphia (CHOP) and holds the Raymond G. Perelman Endowed Chair in Pediatric Neuro-Ophthalmology. He specializes in treating children with neurological disorders that affect vision and eye movements.

Dr. Liu is enthusiastic about the extraordinary level of care CHOP offers to families.

“I want families to come away from their experience at CHOP knowing that they were able to see the best experts in the field to obtain the optimum care for their child,” he said.

Dr. Liu evaluates and treats children with a wide variety of conditions, including 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, pseudotumor cerebri syndrome, abnormal eye movements (ophthalmoparesis or nystagmus), and intracranial lesions affecting the visual pathway.

Along with his role at CHOP, Dr. Liu is a Professor of Neurology and Ophthalmology at the Perelman School of Medicine at the University of Pennsylvania. He is considered an international expert on pediatric neuro-ophthalmic topics such as pediatric pseudotumor cerebri syndrome, vision testing in children with neurofibromatosis and optic pathway gliomas, and pediatric optic nerve disorders.

His research focuses on understanding the mechanisms and best clinical care for disorders such as pseudotumor cerebri syndrome, optic neuritis and cerebral visual impairment.
