Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
