Objective: To report the case of a 43 years old patient with sclerochoroidal calcifications and subretinal neovascular membranes associated with high myopia.
Methods: Description of the biomicroscopic, angiographic (fluorescein and ICG) and echographic findings in a patient with high myopia (-14 Dpt).
Results: On both eyes, we observe tumor-like white lesions, located on the upper temporal arteries, surrounded by a thin hyperpigmentation and of one papillary diameter in width. The lesions are highly reflective in Bechography, with acoustic shadowing typical for calcifications. They measure 1,5 mm in thickness. In the early venous phase of fluorescein angiography, the lesions show a patchy and a circular hyperfluorescent pattern in a hypofluorescent disc-shaped zone. They are surrounded by a circular choroidal hyperfluorescent area, that fades slightly in the late phase. The hyperfluorescent patterns stain in the late phase, without diffusion of the fluorescein. The ICG-angiography shows an image similar to that in fluorescein-angiography, with a very discrete perilesionnal choroidal hyperfluorescence.
Conclusion: The features of the observed lesions appear typical for sclerochoroidal calcifications. In this case, we observed the association with fibrosed subretinal membranes in a highly myopic patient. This patient had no anomalies of his calcium and phosphor metabolism, so that we consider these calcifications as dystrophic.
