Diabetic retinopathy is a microvascular complication of diabetes and needs yearly fundus screening. Nonmydriatic cameras makes fundus photography far more patient-friendly by eliminating the need for bright lights and dilating drops.
In turn, eliminating the 30-minute wait for the pupil to dilate and the time for the eye to adjust following a flash of light speeds the exam. This further benefits the patient and saves time. This feature also is helpful with glaucoma patients for whom dilation is contraindicated.
