Three fundus imaging systems: (a) Conventional five-field fundus imaging; (b) Covered Optos fundus imaging; (c) Covered Clarus fundus imaging; (d) Optos fundus imaging; (e) Clarus 133° fundus imaging; (f) Clarus 200° fundus imaging. Arrow indicates microaneurysms or hemorrhage. Notably, the microaneurysms or hemorrhage is difficult to identify because of lower contrast for Optos fundus imaging.
