Changes in the osmotic pressure of vitreous fluid and sub-silicone oil fluid (SOF) from the same eyes. (a) The average SOF osmotic pressures from RRD, PVR, PVR, and MHRD. There were no significant difference between four groups. (b) The X-axis indicates the duration of SOF inside the eye and the Y-axis indicates the osmotic pressure. Note that the osmotic pressures in the vitreous fluid and SOF were not altered regardless of the disease or SOF duration. RRD: Rhegmatogenous retinal detachment, PDR: Proliferative diabetic retinopathy, MHRD: Macular hole-associated retinal detachment.
