Diabetic retinopathy is a complication of diabetes mellitus. Diabetes damages the normal circulation of the body. That is why diabetics have problems with the circulation to their legs, kidneys, heart, brain and eyes.
In the early stage of diabetic retinopathy called Non Proliferative Diabetic Retinopathy (NPDR), Diabetes causes the blood vessels in the retina to leak and form deposits called exudates.
These leaky blood vessels create a complication called Macular Edema or retinal swelling, and are the most common cause of vision loss in diabetics. Macular Edema is diagnosed using fluorescein Angiography (FA) and Ocular Coherence Tomography (OCT).
Ocular Coherence Tomography (OCT) is a method of high resolution digital imaging that allows clear cross sections of the retina and its layers to be directly observed, in much the same way as a CT scan allows us to observe high resolution images of other tissues and organs of your body.
