To avoid any evaluation bias, image type (real glaucoma/real normal/synthetic glaucoma/synthetic normal) of the 200 images was not revealed to either of the clinicians. Image quality of each of the 200 images was graded by both clinicians. Values indicate the number (%) of images graded as good quality.
