Welcome to the Pathologic Myopia Challenge! PALM is organized as a half day Challenge, a Satellite Event of the ISBI 2019 conference in Venice, Italy.


The PALM challenge focuses on the investigation and development of algorithms associated with the diagnosis of Pathological Myopia (PM) and segmentation of lesions in fundus photos from PM patients. The goal of the challenge is to evaluate and compare automated algorithms for the detection of pathological myopia on a common dataset of retinal fundus images. We invite the medical image analysis community to participate by developing and testing existing and novel automated fundus classification and segmentation methods.

Thanks for your interest and patience. PALM challenge, as a part of the serial challenge iChallenge, opens to the public on Dec 28 2018. Training data of the 1st classification task will be released on a new platform in early Jan 2019, for better management, including 1) automatic performance evaluation;    2) better communication between organizers and participants; 3) higher download speed for participants around the world; 4) other benefits.

Please don't mind if your participation request is not approved on this platform, we will batch process the request before data releasing.
