Figure 3
Surface contour in the prone with closed eyes position, with 90% gas to the vitreous cavity. (A) From the side view. The gray translucent blockage represents the water object set to have a 10% volume to the vitreous cavity before fluid analysis. The surface contour represents after analysis. (B) Enlarged image of (A). The black arrows indicate the initial height of the water before analysis, and the white arrows indicate the line where the SURN is 0.0, which indicates complete coverage by the gas after analysis. The existence of surface tension and contact angle cause the line of the SURN = 0.0 to rise above the initial water level, which leads to a reduction in the gas cover rate of the retina.
