  1. Choroidal Thickness (μm) in different locations in groups of progressive and non-progressive Keratoconus. Results are expressed in Mean (± SD). Progressive KC was defined when at least two of the studied variables confirm progression. Measurements undertaken at subfoveal choroid (Fov), temporal 500 μm (T500), 1000 μm (T1000), 1500 μm (T1500), and nasal 500 μm (N500), 1000 μm (N1000) and 1500 μm (N1500).
