Severe myopia (myopia magna, myopia maligna) predisposes the patient to macular haemorrhages ('Fuchs spots') at an early age. The retina and subretinal tissues have become thinner when the eye has become longer. There is a grey oedema in the central macula, and a haemorrhage around it. Note the peripapillar atrophy and narrow vessels. The choroidal vessels are more visible than usual.
