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

December 19, 2013 updated by: Dong Ho Park, Kyungpook National University Hospital
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.
