“…This versatility comes with the limitation of needing an expert operator to obtain high-quality images and perform the measurements. Astronauts on the ISS have successfully performed the ocular US with remote guidance and have obtained good quality US images 26 . While MRI and US measurements of the same subject at the same time point showed excellent consistency 27 , it is not possible to use this data from different SANS ONSD studies interchangeably due to the variability in timing and measurement methods.…”

Neuro-ocular changes during long-duration space flight are known as spaceflight-associated neuro-ocular syndrome (SANS). The ability to detect, monitor, and prevent SANS is a priority of current space medicine research efforts. Optic nerve sheath diameter (ONSD) measurement has been used both terrestrially and in microgravity as a proxy for measurements of elevated intracranial pressure. ONSD shows promise as a potential method of identifying and quantitating neuro-ocular changes during space flight. This review examines 13 studies measuring ONSD and its relationship to microgravity exposure or ground-based analogs, including head-down tilt, dry immersion, or animal models. The goal of this correspondence is to describe heterogeneity in the use of ONSD in the current SANS literature and make recommendations to reduce heterogeneity in future studies through standardization of imaging modalities, measurement techniques, and other aspects of study design.

“…The subject also watched a medical video demonstrating a person performing self-ultrasound 15 . It was shown that both remote guidance and a computer training tool produce a higher quality of ultrasound images 6,9 . During the procedure, the subject performed the test while guided remotely by the sonographer, who was in a separate location from the subject.…”

“…4 Additionally, ultrasound examination of the eye (which allows for the rapid assessment of the cerebral edema) is easy enough to be taught and used by non-expert operators on the International Space Station (ISS). 5,6 To date, there is an increasing number of ultrasound teaching pilot studies. These kinds of activities, used as a supplement to gross anatomy courses, are beneficial even during the first years of study.…”

Background: Ultrasonography protocols are easy to learn, frequently used in emergency medicine, and could be useful for inexperienced doctors. Inthis field, only a few protocols are needed to give an initial diagnosis and to start fast and proper treatment. Until now, only Focused Assessmentwith Sonography for Trauma (FAST) protocol training studies have been reported in the medical literature. Our point-of-care course, comprisedof extended FAST, lung scan and ocular scan trainings. The students’ curriculum usually does not include such ultrasonography courses, thus,we wanted to check its utility for the undergraduate medical students. Methods: Training lasted six days and consisted of two parts: 22 hoursof theoretical classes and 18 hours of practical activities, all trained and evaluated by six experienced medical doctors. Eighty-five electedstudents completed pre- and post-study questionnaires about emergency ultrasonography and passed the practical final exam. Results: Eighty-fiveparticipants of the course were present in the pre- and final test. Final test scores of theoretical and practical exams were significantly higherafter the training (58% vs. 87%; n=85; p<0.01). Answers for the questions related to FAST and EFAST (extended FAST) were correct irrespectiveof completion of the course. A question regarding the sonographic evaluation of body fluid incontinence was found to be the most difficult forstudents. After the course, 96.5% of participants were able to complete an EFAST scan at an adequate level of performance in under two minutes.Conclusion: Results show that medical students significantly extended their knowledge about point-of-care emergency medicine ultrasonographyand acquired practical skills during the course. Emergency medicine ultrasonography courses could be included into medical students’ curricula.
