The direct posterior traction (blue arrows) exerted by the scleral insertions of the optic nerve sheaths would lead to the outpouching of the sclera while the thinning of the choroid at the PPS edge ...

Vision changes in astronauts after extended space missions Spaceflight-associated neuro-ocular syndrome affects 70% of astronauts Reduced ocular rigidity and pressure observed in space conditions ...

The low levels of gravity (microgravity) in space cause significant changes in astronauts’ eyes and vision after six to 12 months aboard the International Space Station (ISS), according to a study.

Weightlessness may lead to lasting eye changes due to mechanical shock The researchers suggest that the choroid’s expansion in weightlessness may stretch the collagen in the sclera, causing ...

According to the researchers, the expansion of the choroid during weightlessness could stretch the collagen in the sclera, the white outer layer of the eye, causing long-lasting changes in the eye's ...

Abstract: Due to the inherent imaging characteristics of Optical Coherence Tomography (OCT), the contrast between the choroid and sclera is low, presenting significant challenges in choroidal ...
