Fundoscopic appearance of Proliferative Diabetic Retinopathy.
Fundoscopic appearance of Proliferative Diabetic Retinopathy.

For a patient with proliferative diabetic retinopathy (PDR), the overarching goal is to reduce disease severity. You can help drive patient outcomes through early detection, monitoring, and timely referral.1-3

A severity scale can help identify and standardize the clinical features of Diabetic Retinopathy (DR) at various stages and allow for early detection and timely intervention.1,4-6

ETDRS-DRSS Score: 61

CRT: 275 μm

IOP: 18 mm Hg

ETDRS Letters: 69

Snellen Equivalent: 20/40

HbA1c: 11.5

BMI: 33

Note: This is a representative case example that you may encounter in clinical practice.

BMI = body mass index; CRT = central retinal thickness; ETDRS-DRSS = Early Treatment Diabetic Retinopathy Study–Diabetic Retinopathy Severity Scale; HbA1c = glycated hemoglobin; IOP = intraocular pressure; NVD = neovascularization of the disc; NVE = neovascularization elsewhere.
