- Professor of Electrophysiology (in Ophthalmology) at CUMC
Dr. Greenstein's primary research aims are: To understand the mechanisms involved in diseases affecting the retina and optic nerve and to improve methods for detecting retinal and/or optic nerve damage caused by these diseases. A variety of non-invasive structural (e.g. optical coherence tomography (OCT), adaptive optics scanning laser ophthalmoscopy) and functional measures (e.g. visual fields, fundus tracking perimetry, color vision, multifocal ERG and VEP) are used to test specific hypotheses about the sites and mechanisms of diseases affecting the retina and/or optic nerve. With the increase in ongoing and anticipated clinical trials involving retinal disease there is a need for localized measures of retinal function and structure to evaluate treatment efficacy, Dr. Greenstein is now focusing her research on determining how localized measures of visual function in patients with retinal diseases are related to underlying retinal structure using the latest OCT techniques, adaptive optics scanning laser ophthalmoscopy, and fundus autofluorescence.

- The development of a set of noninvasive techniques for studying the mechanisms by which a disease affects different retinal cells. These are techniques that can be used by the ophthalmologist to monitor the disease progression, and assess the effectiveness of alternative treatments.
