Executive Industry Relevance

Reliable assessment of visual pathway integrity in preclinical rat models is critical for de-risking early-stage neuroscience and ophthalmology drug discovery. Simultaneous electroretinography (ERG) and visual evoked potential (VEP) recordings provide quantitative, reproducible endpoints for evaluating retinal and cortical function. This workflow supports predictive confidence in target validation and translational continuity for visual system therapeutics.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables objective interrogation of visual pathway function in disease-relevant models.
• Supports mechanistic de-risking by distinguishing retinal from cortical deficits.
• Provides functional endpoints for validating visual system targets.

Screening & Assay Development

• Establishes standardized, reproducible electrophysiological assays for compound evaluation.
• Facilitates quantitative measurement of retinal and cortical responses to interventions.
• Prepares validated animal models for downstream screening workflows.

Translational & Preclinical Research

• Aligns preclinical endpoints with translational biomarkers of visual function.
• Enables continuity from early discovery through preclinical efficacy studies.
• Supports risk-adjusted advancement decisions for visual system drug candidates.
