Species Studied
Scientific Name: Homo sapiens Species: Human


Ocular Test is one of eleven International Bedrest Standard Measures conducted on healthy subjects at the :envihab facility in Cologne, Germany. Ocular Tests consist of assessing Intraocular Pressure (IOP), an Ocular Ultrasound, and Optical Coherence Tomography (OCT) and A-scan. The purpose of the standard measures project is to populate a repository with data that enables high-level monitoring of countermeasure effectiveness and meaningful interpretation of health and performance outcomes. These standard measures will support future, hypothesis-driven research that enables planetary missions by providing an optimized minimal set of measures captured from subjects. These measures will be available to other studies under data sharing agreements as well as undergo analysis to understand risk posture.
