This paper investigates uncertainty-aware adaptation techniques for a self-supervised vision-transformer model called RETFound, specifically for screening diabetic retinopathy. The study evaluated various methods, including Bayesian last-layer heads and post-hoc calibration, on the APTOS 2019 and DDR datasets. While uncertainty-aware approaches showed promise in improving sensitivity and selective-referral behavior on the APTOS dataset, their effectiveness diminished on the DDR dataset, highlighting the challenges of dataset shift and the need for explicit safety-coverage evaluation.
