Practical instruments for fundus photography perform the following modes of examination: Colour, where the retina is illuminated by white light and examined in full colour. Red free fundus photography utilizes a filter in order to better observe superficial lesions and some vascular abnormalities within the retina and surrounding tissue. A ...

Frequently, retinopathy is an ocular manifestation of systemic disease as seen in diabetes or hypertension. [3] Diabetes is the most common cause of retinopathy in the U.S. as of 2008. [4]
