Subfoveal Choroidal Thickness in Retinal Vein Occlusion

Since Spaide et al described the enhanced depth imaging mode of optical coherence tomography to visualize the choroid, an increasing number of studies have examined choroidal thickness and its associated factors in normal eyes and eyes with various retinal and retinochoroidal disorders. The studies revealed that the mean subfoveal choroidal thickness (SFCT) in normal eyes is approximately 250 μm at age 65 years; that SFCT shows a marked interindividual variability with values as low as 8 μm and values as great as 854 μm; that SFCT decreases by about 4 μm (Read more...)
