Ocular Outcomes Comparison Between 14- and 70-Day Head-Down-Tilt Bed Rest Open
Seventy-day HDT BR induced greater peripapillary retinal thickening than 14-day HDT BR, suggesting that time may affect the amount of optic disc swelling. Spectralis OCT detected retinal nerve fiber layer thickening post BR, without clinic…
