Retinal sparing in diabetic retinopathy.
Asymmetrical involvement of the retinas in diabetic retinopathy is rare. The cause of this "sparing" of one retina is important in terms of the possibility of coexisting or superimposed ocular or vascular disease. Asymmetrical retinal involvement also reflects a pathophysiologic element in the progression of diabetic retinopathy, namely, the concept of net retinal vascular pressure as it affects the degree of observable retinal disease in diabetics. An illustrative case was presented, along with a review of similar cases reported in the literature.
