Intraocular Pressure and Ocular Perfusion Pressure in Myopes During 21 min Head-Down Rest

Abstract

Abnormal auto-regulation of ocular blood pressure in myopes of moderate and greater severity may pose a risk factor for developing ocular hypertension and possibly glaucoma when exposed to microgravity. HDR may offer a method of screening candidates for spaceflight for this risk prior to microgravity exposure.
