The Visual Function Core was established in 2017. This core provides an eye phenotype evaluation service to all investigators at Weill Cornell Medicine, Cornell University and Cornell-affiliated institutions. The facility also provides services to external investigators at both academic institutions and commercial enterprises.
Quantitative vision tests in animals
- Electroretinography (ERG), gives an assessment of scotopic (low light) and photopic (daylight) vision. ERG also provides insight into which cells may have a deficit in visual perception.
- Optomotor response (OMR), assessment provides a measure of visual acuity and contrast sensitivity.
Eye imaging in live animals
- Slit lamp gross morphology evaluation of the anterior or posterior of the eye.
- Optical Coherence Tomography (OCT) imaging yields a cross-sectional view of the retina and optic nerve.
- Angiography of both retinal blood flow (with fluorescein) and choroidal blood flow (with indocyanine green).
- Retinal cameras provide complementary imaging of the front and back of the eye.
Histological analysis of the eye
- Morphological analysis of the eye. Sectioning by various techniques, retinal & corneal flat mounts can be stained by immunofluorescence and other staining such as H&E.
- Primarily offered as a screening service for mutant mouse strains, this service provides a basic report on visual function and eye morphology. Detailed reports are also available.
