Ophthalmologic Concerns

This chapter reviews ophthalmic issues associated with spaceflight operations. Current vision standards for space flight, methods of vision correction for spaceflight crewmembers, and vision demographics are discussed, followed by clinical conditions that could affect spaceflight duties and common ocular emergencies that could occur during space operations. The current medical selection and retention standards ensure that space crewmembers are generally healthy, free of significant chronic disease, and are not taking medication on a long-term basis. This chapter focuses primarily on ocular abnormalities that might be expected in healthy subjects during exposure to microgravity.
