Method to measure the height of the foveal detachment by ultrasonography.
a. Schematic drawing of the measurement of the distance between the center of the optic nerve head and fovea, and assessment of the angle between their connecting line with the horizon. b. Drawing of the measurement of the distance between the center of the optic nerve head (determined by drawing a circle along the outer edge of the optic disc, excluding the area of peripapillary atrophy) and fovea, and assessment of the angle between their connecting line with the horizon made on a fundus photograph. c. Schematic position of the ultrasound probe at the correct angle between the horizon and the connecting line between the center of the optic nerve head and the fovea based on the measurement made on the fundus photograph d. Measurement of the height of the retinal detachment by ultrasonography at the measured distance between the center of the optic nerve head and the fovea, as obtained by measuring this distance on the fundus photograph.
