FIELD: medicine; ophthalmology.
SUBSTANCE: invention can be used to diagnose retinoblastoma minor (RB) in children. Retinal vessels are visualized using OCT angiography. If there are 17 or more yellow pixels in the area of the pathological focus, no more than 5 vascular arcades in the deep layers of the focus and there are no vessels at the level of the outer retinal layer, small RB is diagnosed.
EFFECT: invention provides the possibility of objective diagnostics of small RB due to the criteria obtained using OCT angiography.
