Animals used for research:  Mouse, Rabbit, Rat 

Experimentica’s Research & Development Division is actively developing novel in vivo models for a number of indications. Some of our current activities include the development of artificial corneas for permeability screening, development of standardized and validated readouts in novel models for diabetic retinopathy, identification of pathophysiological processes in meibomain gland dysfunction, and innovative approaches to induce demyelination of the optic nerve to mimic optic neuritis.

Utilizing state-of-the-art technology for the longitunial in vivo imaging of ocular tissues, such as spectral-domain ocular coherence tomography, fluorescein angiography and vitreofluorophometry, paired with traditional histological and molecular readout, we are able to detect early patholofical changes with unprecedented accuracy.

We look forward to an opportunity to partner with you to refine or develop almost any custom in vivo project. Over the years, we have worked with numerous pharmaceutical and biotech companies and academic institutions to either implement models previously described in the scientific literature or to develop novel models for ophthalmic disease indications.
