Artificial intelligence detects retinal fluid on OCT in AMD better than retinal specialists

Posted on

An artificial intelligence algorithm was able to detect retinal fluid on OCT scans with a higher level of accuracy than retinal specialists, according to a presentation at the 2020 ASRS Virtual Meeting.

In this prospective study, SD-OCT scans from 651 participants (1,127 eyes) were graded for intraretinal and subretinal fluid by artificial intelligence (AI)-based Notal OCT Analyzer (NOA) and reading center (RC) graders.

Retinal fluid was present in 370 eyes. Investigators’ accuracy was 0.805 (95% CI 0.780-0.828), sensitivity was 0.468 (0.416-0.520), and specificity of 0.970 (0.955-0.981) compared to NOA accuracy was 0.851 (0.829-0.871), sensitivity was 0.822 (0.779-0.859), and specificity of 0.865 (0.839-0.889).

Investigator performance in regard to detecting intraretinal fluid was 0.815 (0.792-0.837) for accuracy, 0.403 (0.349-0.459) for sensitivity, and 0.978 (0.966-0.987) for specificity; NOA was 0.877 (0.857-0.896), 0.763 (0.713-0.808), and 0.922 (0.902-0.940), respectively.

The authors concluded: “This software tool could assist physicians in detecting retinal fluid, which is important for retreatment and prognostic tasks in AMD.”
