the fundus. Patients shall put the chin on the chin rest and lean the forehead on the forehead rest.
The operator shall operate it manually to focalize and align to the fundus, and capture the fundus
images upon clicking, with such images directly shown on the touch screen. Ophthalmologists
will trace the progression of eye diseases on the basis of such retinographs, which will serve as the
basis of diagnosis and treatment.
