Optical Coherence Tomography Angiography in Neurological Disease

Recruiting

• Conditions: Octa; Stroke; Subarachnoid Hemorrhage; Intracerebral Hemorrhage

• Registration Number: NCT06797765
• Lead Sponsor: University of Texas Southwestern Medical Center

Brief Summary

Optical Coherence Tomography Angiography (OCTA) is a non-invasive tool that images the neurovascular structures of the eye by using near-infrared light. Previous literature has demonstrated the potential of OCTA as a screening tool in stroke, but its utility in other neurological illness such as intracranial hemorrhage is unclear. Hence, this pilot study will gather preliminary data to support future grant applications to investigate this area more fully by recruiting patients with neurological illness and healthy controls and comparing their OCTA imaging parameters.

Primary Outcome Measures

Name	Time	Method
Vascular and Perfusion Density in healthy controls	Once (approx. 10 mins)	Quantitative measure of retinal microperfusion. No definite time points are defined since different neurological diseases have different patterns of evolution and patient/provider availability may change.
Vascular and Perfusion Density in Patients with neurological disease	Throughout study completion up to 28 days	Quantitative measure of retinal microperfusion. No definite time points are defined since different neurological diseases have different patterns of evolution and patient/provider availability may change.
