These results indicate that macular choroidal blood flow velocity decreases concurrently with regression of CSC, suggesting a validity of choroidal blood flow elevation in the pathogenesis of acute CSC.

A rapid and selective protein labeling method, LDBB chemistry is a useful tool for natural protein imaging in living cells.

Our data suggest that circulatory disturbances and increased thickness of the choroid relate to the pathogenesis of VKH disease with link mutually. LSFG is useful as an index for evaluating the choroiditis activity of VKH disease as well as EDI-OCT.

BackgroundThe mechanism underlying focal choroidal excavation (FCE) remains largely unknown. We evaluated the sequential progression of FCE generation using enhanced depth imaging optical coherence tomography (EDI-OCT) in a patient with multiple evanescent white dot syndrome (MEWDS).Case presentationA 37-year-old woman suffered MEWDS in the right eye. EDI-OCT showed the loss of photoreceptor inner segment/outer segment junction line, detachment between the retinal pigment epithelium (RPE) and Bruch’s membrane, and dome-shaped, moderately reflective, focal photoreceptor-layer lesions corresponding to perifoveal white dots. The region with pigment epithelium detachment involved RPE/Bruch’s membrane ruptures. After 1 month, almost all white dots spontaneously resolved together with improvements of the perifoveal OCT findings. Interestingly, perifoveal region developed a conforming-type FCE. An abnormal hyper-reflective lesion on OCT, regarded as fibrosis formation, simultaneously appeared within the choroid below the FCE and subsequently increased in size.ConclusionsThese results suggest that the RPE/Bruch’s membrane disruption due to chorioretinal abnormalities and subsequent intrachoroidal scar formation play a role in the pathogenesis on an acquired FCE.
