Idiopathic posterior subretinal neovascularization (IPSN) is related to myopia.

In 153 eyes with idiopathic posterior subretinal neovascularization (IPSN) and myopia of no greater than -6 dpt, the relative risk of this disorder was determined with regard to refraction. It was shown that the probability of developing this condition is directly proportional to the degree of myopia. By using data obtained from the literature for calculating the relative risk regarding refraction, it was demonstrated that the same is true for subretinal neovascularization in degenerative myopia greater than -7.5 dpt (Fuchs' spot). The relative risk for developing one of both disorders increases exponentially with increasing myopia.
