Dylan Dexter Joins the Lab as an Undergraduate Research Assistant
April 14, 2025
We are excited to welcome Dylan Dexter to the Vision Lab as an undergraduate research assistant! Dylan will be working on an exciting project that uses light sheet fluorescence microscopy (LSFM) to image the collagen architecture within the lamina cribrosa of the optic nerve head. Mapping this collagen structure is crucial for understanding the biomechanical environment within the lamina cribrosa under elevated intraocular pressure. This research aims to shed light on why retinal ganglion cell axons initiate in the lamina cribrosa in glaucoma, contributing to our understanding of the disease's underlying mechanisms.

We are excited to welcome Quinn Johnson to the Vision Lab! As an undergraduate research assistant, Quinn will work on a project focused on both the quantitative and qualitative analysis of glycosaminoglycans (GAGs) in the sclera. His work aims to advance our understanding of how GAGs contribute to ocular biomechanics.
Quinn will optimize biochemical assays for GAG quantification and use imaging-based techniques to examine the structural distribution and integrity of GAGs within the scleral tissue. The ultimate goal of his research is to investigate how changes in GAG content influence scleral stiffness and eye shape — factors that play a critical role in ocular diseases such as myopia and glaucoma.

Our paper, titled "Impact of Elevated IOP on Lamina Cribrosa Oxygenation: A Combined Experimental-Computational Study on Monkeys," has been accepted for publication in Ophthalmology Science. This study, conducted in collaboration with Dr. Ian A. Sigal and his lab at the University of Pittsburgh, integrates experimental and computational approaches to investigate how intraocular pressure (IOP)-induced deformations affect oxygenation in the lamina cribrosa (LC). [Preprint]
By combining in vivo imaging data from monkeys with numerical modeling, we quantified the effects of elevated IOP on LC blood flow and oxygen supply. Our findings suggest that even moderate IOP elevations can lead to mild hypoxia in a substantial portion of the LC, potentially contributing to glaucomatous neuropathy.
