Principles of Clinical Medicine for Space Flight

Abstract

This chapter reviews a wide spectrum of ophthalmic issues associated with space flight operations. Current vision standards for space flight and vision demographics are discussed, followed by clinical, anatomic, and physiologic conditions that could affect space flight duties. We will describe more traditional methods of visual correction to include spectacles and contact lenses as well as the utility of several methods of surgical correction. We will also include a discussion of anatomic changes observed in astronauts following long-duration space flight to include disc edema, globe flattening, and hyperopic shifts and review the ground-based and in-flight testing used to study these anomalies. Finally, we discuss common ocular emergencies that could occur during space operations. This chapter focuses primarily on ocular abnormalities that might be expected in healthy subjects during exposure to weightlessness.
