Table 2 Goal of sensitivity and specificity in estimated NPA.

From: Deep-learning-based AI for evaluating estimated nonperfusion areas requiring further examination in ultra-widefield fundus images

Assumed goal

Sensitivity

Specificity

Judgement of FA imaging

 > 80%

 > 70%

Assessment of severe NPDR and PDR in DR

NPA less than 10 DA has a low risk of blindness and can be overlooked by 20% as false negative

It is not necessary to have a majority because FA imaging is not carried out other than for relevant diseases

  1. NPA non-perfusion area, FA fluorescein angiography, NPDR non-proliferative diabetic retinopathy, DA disk area.
