Design outcomes

Primary

Measure	Time frame
The assessment includes the general condition of the patient (ADL, age, underlying disease), environment , possibility of record,image quality ,and whether other doctors can diagnose with the images. Safety is assessed by checking whether there is any ocular damages especially in cornea and retina. Corneal damage is assessed with diagnostic criteria of dry eye( 9-point scale). Retinal damage is assessed by checking the presence of yellow spots of the fovea and other abnormalities by funduscopy. If there are some abnormalities electroretinogram and visual field test.	—
