AGE: Angle closure Glaucoma Evaluation Challenge

Glaucoma is the leading cause of irreversible blindness in the world, and primary angle closure glaucoma (PACG) is one of the main subtypes. PACG patients have narrow chamber angle and can be diagnosed by goniscopy, which may cause discomfort and relies too much on personal experience. Anterior segment OCT is able to provide 3D scan of the anterior chamber and assist the ophthalmologists evaluate the condition of chamber angle. It’s faster and objective compare with goniscopy. Here, we set up the challenge on development of automatic algorithms about grading of angle width and recognition of important anatomical markers such as scleral spur.青光眼是全球导致不可逆失明的主要原因，其中原发性闭角型青光眼（PACG）是主要亚型之一。PACG患者具有狭窄的房角，可通过前房角镜检查进行诊断，但此检查可能引起不适，且过度依赖个人经验。前段光学相干断层扫描（OCT）能够提供前房的三维扫描，协助眼科医生评估房角状态。与前房角镜检查相比，OCT更为迅速且客观。在本研究中，我们针对自动算法的开发提出了挑战，旨在对房角宽度进行分级以及对诸如巩膜嵴等重要解剖标志的识别。
