Abstract

Objective: The purpose of this article is to report the correlation between spectral domain-optical coherence tomography and autofluorescence findings in 3 consecutive cases with sclerochoroidal calcification.

Design: Observational case series.

Participants: The study involved 3 patients with bilateral sclerochoroidal calcification.

Methods: B-scan ultrasonography, spectral domain-optical coherence tomography, and autofluorescence were performed in each eye. The choroidal vascular thickness and autofluorescence patterns of the calcified plaques were evaluated with spectral domain-optical coherence tomography and autofluorescence, respectively.

Results: An important variation of choroidal vascular thickness overlying sclerochoroidal calcification was observed in spectral domain-optical coherence tomography. Autofluorescence showed 2 patterns of autofluorescence closely correlated with changes in choroidal vascular thickness. In those zones where the thicknesses of choriocapillaris complex were reduced, a hyperautofluorescence pattern was observed in autofluorescence. The hypoautofluorescence pattern was observed in outpouching zone of retinal pigment epithelium-choriocapillaris complex seen in spectral domain-optical coherence tomography. The hypoautofluorescence pattern was closely correlated with remarkable reduction of the choriocapillaris complex. There were no significant differences between the patterns of autofluorescence except the extension.

Conclusions: Spectral domain-optical coherence tomography and autofluorescence are noninvasive complementary imaging studies that may help to improve our knowledge about sclerochoroidal calcification. Characteristic patterns of autofluorescence were closely correlated with spectral domain-optical coherence tomography findings. More patients need to be evaluated with both complementary studies to establish conclusions related with these findings.
