光干渉断層撮影法の網膜症モデルマウスへの応用

Executive Industry Relevance

Noninvasive, high-resolution retinal imaging in mouse models using optical coherence tomography (OCT) enables quantitative assessment of retinopathy, supporting early-stage target validation and mechanistic de-risking in ophthalmic drug discovery. The ability to measure retinal thickness and detect neovascularization in vivo enhances predictive confidence and translational continuity from preclinical models to clinical endpoints. This capability is critical for portfolio decisions in retinal disease programs where robust, reproducible biomarkers are required.
