Singular neurectomy (posterior ampullary nere transsection) and posterior semicircular canal occlusion are the 2 specific techniques used in intractable BPP surgery.
Objective To observe the characteristics of fundus images and fluorescin angiography (FFA) in diabetic retinopathy (DR) combined with retinal vein occlusion (RVO).
