Smith Lab - Investigating Vascular Eye Diseases

The Retina and Vascular Development

Our lab investigates factors regulating the vascular development of the retina using several in vivo models. We are dedicated to developing ways to improve therapies for vascular eye diseases, such as retinopathy of prematurity, diabetic retinopathy, and age-related macular degeneration.

A Mouse Model of Vascular Diseases

The mouse model of retinal development has been studied intensively and provides an easily observable representation of vascular development. Unlike humans, mice have an immature retinal vasculature at birth and development continues for the first thirty days. The organized development of the retinal vasculature allows us to reliably observe any abnormal development and investigate the impact of different factors.

We currently use both transgenic and knockout animals, pharmaceuticals, and dietary modification to investigate multiple genetic pathways regulating retinal development.
