Abstract

The retinal vascular pulse is a biomarker in the management of ophthalmic and systemic disorders. Retinal vascular pulse measurement techniques have been described in the literature; practical limitations have mitigated their applicability. Modified photoplethysmography is a novel non-invasive imaging method where a video of the retinal vessels at the optic nerve with simultaneous ophthalmodynamometry enables testing under a range of induced intraocular pressures in the spatiotemporal and frequency domains. The core finding of this thesis is an artificial intelligence model, which provided an accurate, non-invasive intracranial pressure prediction from retinal vascular pulse amplitude features in the frequency domain.
