I am a neuro-ophthalmologist with a special interest in the neuro-ophthalmic complications of cancer and brain tumors; including vision loss, double vision, nystagmus (shaking of the eyes), and pupil changes. I am the director of neuro-ophthalmology at NewYork-Presbyterian Hospital/Weill Cornell Medical Center and have the privilege of performing neuro-ophthalmological consultations for patients at Memorial Sloan Kettering Cancer Center. My research interests include the effects of cancer, and especially leptomeningeal disease, on the optic nerve and the immune effects of certain cancers (paraneoplastic disease) on the optic nerve and retina.
Tumors of the pituitary and its surroundings commonly cause vision loss by compressing the optic chiasm or optic nerves, requiring close monitoring of visual function. I am particularly interested in the ability of new technologies such as optical coherence tomography (OCT) to predict whether or not surgical intervention might improve a patient's vision. I am also interested in papilledema, a swelling of the optic nerves that occurs with elevated head pressure, and its effects on vision in patients with brain tumors. Vision is pivotal to patients' daily quality of life, and I am committed to doing everything I can to preserve vision for our patients.
