A TECHNIC FOR PHOTOGRAPHING HUMAN RETINAL CIRCULATION DURING BLACKOUT ON THE USAFSAM HUMAN CENTRIFUGE

Abstract

To study the human retina on a moment-to-moment basis during the rapid sequence of events occurring before, during, and after a blackout episode on the human centrifuge requires a technic which will not harm the subject, yet will allow constant viewing. In a previous study an ophthalmoscope was used to study the retinal changes and then the subjective impressions of the investigator were recounted to a medical illustrator. A method has now been developed using a modified Zeiss fundus camera which allows photographs to be taken of the retinal circulation every 0.6 second during the entire +G maneuver at the subject's blackout level.
