From: Minification of fundus optical coherence tomographic images in gas-filled eye
Degree of reduction of OCT images in gas-filled eyes. The vertical length of the optic disc was 23.5 % shorter in gas-filled eyes than the same eyes after the gas had been absorbed and the eye was fluid-filled (a, P < 0.01). The horizontal width was 26.5 % narrower in gas-filled eyes than after the gas is absorbed and the eye is fluid-filled (b, P < 0.01). The area of the optic disc of gas-filled eye was significantly smaller than eyes after the gas was absorbed by 40.4 % (c, P < 0.01)
