“…In addition, stroke patients with ROAF have been reported to have worse outcomes than patients without ROAF [ 4 , 8 ]. When one segment of neurological tissue is in a compromised hemodynamic state, it redirects blood flow from ocular tissue, resulting in ROAF and a decrease in OPP [ 9 , 10 ]. Reduced OPP can lead to progressive vision impairment and functional decline in ocular tissues, including chorioretinal ischemia and rubeosis.…”

Innovative applications of clinical ocular diagnostic tools are emerging to help identify systemic disorders that extend beyond ocular diseases. Ophthalmodynamometry (ODM) is a screening tool that non-invasively determines mean central retinal artery pressure (MCRAP) and ocular perfusion pressure (OPP). Decreased OPP and MCRAP on Falck Medical Multifunctional Device (FMD, Falck Medical, Inc., Mystic, CT), along with reverse ophthalmic artery flow (ROAF) on transcranial Doppler ultrasonography (TCD), indicate increased collateral brain perfusion and possible stenosis of the ophthalmic artery or internal carotid artery (ICA). In this case report, we describe the case of a 78-year-old female with ROAF, reduced MCRAP, and OPP in the right eye, confirmed by carotid duplex of 50-79% right ICA stenosis. Early application of ODM and TCD allowed for prompt diagnosis and management with a vascular specialist.
