Ovariectomy drives increase of an ECM transcription signature in the posterior eye and retina.

Increased risk of developing glaucoma has recently been associated with early age of menopause. Here, we examined how age and surgically-induced menopause via ovariectomy (OVX) impacted gene expression in gene pathways previously linked to glaucoma, such as extracellular matrix (ECM) remodeling and TGF-β signaling. Using bulk RNA sequencing, we analyzed changes in young (3-4 months) and middle-aged (9-10 months) Long-Evans rats.

Improved magnetic delivery of cells to the trabecular meshwork in mice.

Glaucoma is the leading cause of irreversible blindness worldwide and its most prevalent subtype is primary open angle glaucoma (POAG). One pathological change in POAG is loss of cells in the trabecular meshwork (TM), which is thought to contribute to ocular hypertension and has thus motivated development of cell-based therapies to refunctionalize the TM. TM cell therapy has shown promise in intraocular pressure (IOP) control, but existing cell delivery techniques suffer from poor delivery efficiency.

AxoNet 2.0: A Deep Learning-Based Tool for Morphometric Analysis of Retinal Ganglion Cell Axons.

Purpose: Assessment of glaucomatous damage in animal models is facilitated by rapid and accurate quantification of retinal ganglion cell (RGC) axonal loss and morphologic change. However, manual assessment is extremely time- and labor-intensive. Here, we developed AxoNet 2.
