New UPolarSQ framework improves optic disc and PPA analysis in fundus images

By PulseAugur Editorial · [1 sources] ·

Researchers have developed UPolarSQ, a novel framework for segmenting and quantifying optic disc (OD) and peripapillary atrophy (PPA) in fundus photographs, particularly for myopia-induced changes. This system utilizes a polar representation to map OD-centered regions, allowing for more accurate modeling of irregular PPA boundaries. UPolarSQ employs a U-Net-based segmentation network with a specialized module to capture anisotropic polar features and radial transitions, enabling deterministic extraction of clinical biomarkers like disc shape and PPA width. AI

IMPACT Enhances diagnostic capabilities for eye conditions by improving the accuracy of segmentation and quantification of key biomarkers in fundus images.

    UPolarSQ: Polar Representation Learning for Optic Disc and Peripapillary Atrophy Segmentation and Quantification in Fundus Photographs

    arXiv:2608.08771v1 Announce Type: new Abstract: Myopia-induced posterior-pole remodeling is frequently accompanied by Optic Disc (OD) deformation and Peripapillary Atrophy (PPA), both of which provide clinically relevant structural biomarkers. In Cartesian fundus images, however,…
