Qualitative expert assessment of the condition of a patient’s oсular fundus in severe and advanced stages of proliferative diabetic retinopathy

Objective: comparative qualitative expert assessment of the condition of the patient’s fundus in severe and advanced stages of proliferative diabetic retinopathy (PDR). Material and methods. An assessment was made of the developed qualitative criteria for the condition of the fundus in patients with the following stages of PDR: severe-high risk 1 (SHRPDR-1, 32 eyes), severe-high risk 2 (SHRPDR-2, 32 eyes) and advanced (APDR, 34 eyes). The developed criteria (preretinal hemorrhage, fibrosis of the posterior hyaloid membrane, vitreous hemorrhage, etc.) were assessed by one ophthalmic surgeon on a point scale: 1 point - initial changes; 2 - weak, but more pronounced (compared to 1 point) changes; 3 - severity of moderate changes; 4 - pronounced changes.
