Assessment
Primary outcomes
Choroidal and retinal thicknesses (at the fovea, nasal and temporal portions 3,000 micrometer from the fovea) were compared between the two groups.
Key secondary outcomes
Axial length and refractive error were compared between groups.

In group 1 (n=19), the average foveal, nasal, and temporal choroidal thicknesses were 69, 57, and 88 micrometer, refractive error was -10D, axial length 28mm, and the average foveal, nasal, and temporal retinal thicknesses were 170, 222, and 209 micrometer. In group 2 (n=17), the respective values were 175, 80, 174 micrometer, -2D, 24mm, 213, 278, and 253 micrometer. There were significant between group differences for all items (p<0.05) except age.
