Pigmented free-floating vitreous cyst.

A 45-year-old man presented with a mobile shadow in the central visual field of his left eye for the preceding 4 months. His visual acuity was not affected. Funduscopy showed a brownish, oval-shaped structure floating in the vitreous cavity of the left eye. B-scan ultrasound demonstrated an oval-spherical hypoechogenic structure floating at the posterior pole. The absence of pertinent medical history and normal results from systemic exploration suggested a congenital etiology. The condition was observed regularly without any evidence of change. Differential diagnosis of vitreous cysts is important in order to establish an adequate therapeutic approach.

Correlation between spectral-domain optical coherence tomography and autofluorescence findings in sclerochoroidal calcification.

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.
