Pavingstone degeneration appears as small white prolate or oval foci of choroidal retinal atrophy with well-defined borders, which may be accompanied by massive pigmented spots. Choroidal vessels are clearly visible in the lesions. The lesions are mainly in the equatorial region, especially in the posterior pole, with scleral thinning and formation of scleral chylomalacia in the posterior pole. The choroid is thin, the stromal pigment is lost, the number of vessels is reduced, and the small vessels and capillaries disappear. the Bruch’s membrane is thin and may rupture. Significant atrophy of the ciliary body, mainly due to hypoplasia of the annular muscle fibers. The choroidal retina is atrophied and the RPE in the atrophic area disappears completely. the RPE proliferates significantly to form Fuchs, which is covered with a gelatinous, cell-free exudate. Myopia is now confirmed to be the result of a combination of genetics and environment, with genetics playing a very important role in degenerative myopia. Patients with high myopia need to be monitored regularly and should pay attention to eye hygiene.
