The Effect of Postural Changes on Intraocular Pressure in Silicone Oil-filled Eyes

N/ACompletedNCT01992510

Kyungpook National University Hospital22 enrolled

Overview

The study was conducted to investigate how postural changes including sitting, supine, and LDP(lateral decubitus position) affect the IOP(intraocular pressure) of SO(silicone oil-filled eyes. In addition, this study compared the IOP changes between the SO-filled eyes and the fellow eyes in each body position.
