Glaucoma and Choroidal Thickness

Since the landmark study by Spaide and colleagues on the development of enhanced depth imaging by optical coherence tomography, an increasing number of studies have addressed choroidal thickness in normal eyes, factors associated with choroidal thickness in normal eyes, and associations of choroidal thickness with various retinal and retinochoroidal disorders.1-4 These studies have revealed that mean subfoveal choroidal thickness (SFCT) in normal eyes is approximately 250μm in a population with mean age of 65 years,5 that it shows huge variability ranging from values as thin as 8μm to as large as 854μm, that it decreases with age by 4μm per year of older age and by 15 μm per diopter o
