Study Details

Study Description

Brief Summary

Fundoscopy, optical coherence tomography (OCT) and OCT-angiography (OCTA) are established examinations and bear minimal risks. The recognition of retinal microvascular signs will enhance the pathophysiological understanding of the vasculopathy in patients with intracerebral haemorrhage (ICH) and aneurysmatic subarachnoid hemorrhage (aSAH) and might serve as prognostic and diagnostic indicators.

Condition or Disease Intervention/Treatment Phase
  • Diagnostic Test: OCT and OCTA
N/A

Detailed Description

The purpose of the study is to

  • To evaluate the feasibility of fundoscopy, OCT and OCTA imaging in the environment of a Neurocritical Care Unit (NCCU)

  • To detect, quantify and associate microvascular changes in the retina with signs of micro-vessel disease in ICH and DCI in aSAH
