Disease models
High IOP-Induced Ischemia-Reperfusion Injury
In 1996, Adachi et al. introduced a rat model of high intraocular pressure-induced ischemia and reperfusion injury induced by acutely increasing the intraocular pressure for a period of time (1). Accute increase of the intraocular pressure mimics primary open-angle glaucoma & acute angle-closure glaucoma by causing formation of reactive oxygen species, breakdown of inner blood-retinal barrier, and eventually retinal ganglion cell death.
Recent advancements in in vivo imaging and electrophysiology turned this model into a powerful and validated tool for the screening of novel drug candidates with neuroprotective properties. Further innovations in AI-driven image recognition offers more precise and accurate screening of novel drug candidates.
