Quantification of Retinal Ganglion Cell Somas Following Cauterization-Induced Ocular Hypertension

Executive Industry Relevance

Quantitative assessment of retinal ganglion cell (RGC) loss following induced ocular hypertension provides a robust preclinical model for evaluating neurodegeneration mechanisms relevant to glaucoma. This workflow enables high-confidence measurement of cell viability and degeneration, supporting early-stage target validation and mechanistic de-risking in ophthalmic drug discovery. Reliable quantification of RGC density informs portfolio decisions at the intersection of neuroprotection and ocular disease research.
