Pathological Myopia (PM)
Myopia has become a global burden of public health. Among myopic patients, about 35% have high myopia. Myopia leads to elongation of axial length, potentially causing pathological changes in retina and choroid. With an increase in myopic refraction, high myopia will develop into pathologic myopia, which is characterized by formation of pathologic changes at: (1) posterior pole, including tessellated fundus, posterior staphyloma, retino-choroidal degeneration, etc; (2) optic disc, including parapapillary atrophy, tilting, etc; (3) myopic maculopathy, including lacquer crack, Fuchs spot, CNV, etc. Pathologic myopia causes irreversible visual impairment to patients. Therefore, it’s important to have early diagnosis and regular follow-up.
Figure A: Fundus of high myopia; Figure B: Fundus of pathologic myopia, large area of atrophy could be seen.
In the current challenge, we mainly focused on: (1) classification of normal and myopia fundus; (2) segmentation of typical lesions (retinal atrophy, hemorrhage, macular lesion) in pathologic myopia. All the photos were captured with Zeiss Visucam 500.
