Vision is our most far-reaching sense. It allows us to quickly detect information about the environment and enhances our ability to interact with the world around us. Accordingly, many neural areas are devoted to obtaining, processing, and interpreting visual information. When vision is impaired through normal aging or disease processes, the functional implications for a person can be quite significant. This is particularly true when a person is deprived of high acuity, central vision. Many people with bilateral central visual impairments learn to compensate for vision loss by adopting a viewing strategy that involves the use of the peripheral retina. …

Pulmonary artery hypertension is a chronic and progressive disease leading to right heart failure and, ultimately, death if untreated. The goal of the studies in this dissertation was to determine if fluorescein angiography (FA), and color fundus angiography (CF) imaging could be used to garner critical information about retinal changes in individuals with pulmonary artery hypertension (PAH). VESsel GENerational Analysis (VESGEN) is a noninvasive computer program that assigns branching generation to large and small vessels. VESGEN was utilized to investigate vascular alterations in FA, and CF imaging investigating disease progression in PAH. This dissertation demonstrated that PAH patients had aberrant …

This project was conducted in Old World monkeys and focused on characterization of the intrinsically photosensitive retinal ganglion cells (ipRGCs) as they pertain to the pupillary light reflex, as well as on the neuroanatomical and electrophysiological characterization of the suprachiasmatic nucleus (SCN) of the hypothalamus as it pertains to circadian rhythms. A custom antibody was developed against the human melanopsin gene. We validated the antibody using western blot and immunohistochemistry. The functional role of ipRGCs in driving pupillary responses was investigated through immunotoxin-induced ablation in Rhesus macaques with the antibody conjugated to saporin. As hypothesized, the pupillary light reflex and …
