Ocular Imaging

Ocular Imaging will test the use of the SlitTrek headset real-time sensitive imaging platform to detect the following at an early stage:

  • Neurological, neuro-retinal, and circadian rhythm disturbances via high-resolution tracking of the pupillary light reflex to very short (500msec) red and blue light stimuli.
  • Ocular, hemodynamic, and cardiovascular changes by multispectral high-resolution imaging of blood vessels of the anterior of the eye.
  • Innovative advanced image processing algorithms and machine learning (ML) methods to detect spatial-morphological and temporal-morphological changes in the pupil and micro blood vessels in the anterior of the eye.

Analysis of the anatomical and functional ocular changes related to spaceflight
  • Short-duration spaceflight induced consistent structural eye changes
  • Microgravity-driven fluid shifts seem to be the leading mechanism for these changes
  • Both functional symptoms and structural findings occurred in one crew
  • Implications for both short- and long-duration exploration missions
