Dome-shaped maculopathy: a review.

First described by Gaucher and associates in 2008 in eyes with high myopia, dome-shaped maculopathy (DSM) is an anterior convex protrusion of the macula towards the vitreous cavity observable on OCT. This seems to be related to a localized scleral thickness, which might be the result of regional variation in the scleral bio-mechanical properties and the process of emmetropization causing asymmetric scleral growth. The presence of DSM can be associated with an increased risk of complications. The clinical spectrum ranges from being asymptomatic to metamorphopsia and mild-to-moderate gradual visual loss over years. Visual impairment in DSM results from retinal pigment epithelial changes, sub-foveal serous detachment, retinoschisis and myopic choroidal neovascularization. In this review, we compile and review the available information on the pathophysiology, nomenclature, classification, clinical features including imaging, differential diagnosis, complications associated with DSM and the gaps in our understanding of this entity thus far.
