We investigated the circadian change of choroidal thickness using high-penetration optical coherence tomography in healthy volunteers. The significant diurnal change was found and the choroid was thicker at night and thinner in daytime. Fluctuations in the choroidal thickness may be related to SBP.

Patients with active VKH disease have markedly thickened choroids, possibly related not only to inflammatory infiltration but also to increased exudation. Both the choroidal thickness and the exudative retinal detachment decreased quickly with corticosteroid treatment. Enhanced depth imaging optical coherence tomography can be used to evaluate the choroidal involvement in VKH disease in the acute stages and may prove useful in the diagnosis and management of this disease noninvasively.

The subfoveal choroid in the fellow eyes of patients with CSC was thicker in the eyes with choroidal vascular hyperpermeability. Enhanced depth imaging spectral-domain optical coherence tomography can assess the effects of choroidal vascular hyperpermeability by measuring the choroidal thickness noninvasively.

The retinal and choroidal thicknesses were well-correlated between the instruments. Higher reliability and reproducibility are expected for the choroidal thickness measurements despite with higher morphologic interindividual variations.

Half-dose photodynamic therapy for central serous chorioretinopathy resulted in thinner subfoveal choroidal thickness 1 month after treatment, decreased the choroidal vascular hyperpermeability, and maintained the remission for 1 year. Enhanced depth imaging optical coherence tomography was helpful for monitoring the pathophysiologic choroidal changes in central serous chorioretinopathy.
