Getting a Bird’s Eye View

Susana da Silva, PhD

Scientists in the Department of Ophthalmology at the University of Pittsburgh School of Medicine continue to advance their research on a variety of areas that could eventually help solve the puzzle of vision loss. One current area of focus involves studying the fovea. What’s a Fovea? The fovea is a small depression in the retina of the eye where visual acuity is highest. The center of the field of vision is focused in this region, where retinal cones are mainly concentrated. The fovea is responsible for our ability to see colored and sharp vision and perform daily tasks, like reading,

Regenerating the Optic Nerve

Optic Nerve

Dr. Taka Kuwajima, whose team focuses on optic nerve regeneration and mechanisms that lead to nerve cell death in a variety of ocular diseases has recently identified novel molecular pathways that affect nerve cell death at early and late stages of axon degeneration. Visual information is conveyed from the eye to the brain via the optic nerve, an assemblage of nerve cells (called axons) that exit directly from the retina and run to the visual centers of the brain. Damage to the optic nerve from a severe injury or disease invariably leads to vision loss, often resulting in blindness.  Glaucoma,
