Abstract
We investigated the performance of Segment Anything Model (SAM)—the first promptable foundation model for image segmentation—for optic disc (OD) and optic cup (OC) segmentation when fine-tuned on progressively smaller number of fundus images. Three different implementations of SAM with an input prompt were considered: (1) SAM with an OD/OC-centred bounding box (SAM GT); (2) SAM with a noise-added (e.g. displacement, size variation) bounding box (SAM Noise); and (3) SAM with an automatically predicted (using Faster R-CNN) bounding box (SAM Auto). Two popular pre-trained semantic segmentation models, DeepLabV3 with a MobileNetV3-Large backbone and DeepLabV3 with a ResNet-50 backbone were used as baseline models. For OD segmentation, ResNet-50 exhibited comparable if not higher data efficiency (i.e. good performance despite limited training data) than even the most optimal implementation of SAM (SAM GT), although SAM was evidently more robust to small training set sizes, e.g. 25, than MobileNetV3-Large and in eyes with more challenging OD morphologies, e.g. significant peri-papillary atrophy. For OC segmentation, however, SAM GT and SAM Noise consistently demonstrated higher data efficiency, particularly in eyes with relatively small cup-to-disc ratio and ill-defined OC margin.
