Choriocapillaris thickness and density in axially elongated eyes [PDF]
Acta Ophthalmologica, 2020 AbstractPurposeAxial myopia is characterized by a thinning of the choroid. We examined whether the myopic choroidal thinning also includes a thinning of the choriocapillaris.MethodsUsing light microscopy, we measured thickness and density of the choriocapillaris at the posterior pole, posterior pole–equator midpoint (PPEMP), equator and close to the ...
