Respective 1-factor ANOVAs were used to evaluate differences among the three groups (TROP, UROP, CT) in spherical equivalent refraction, axial length, anterior chamber depth, lens thickness, angular subtense, and WS RMS error. The primary independent variables were group and eccentricity, but SLO-confocal, SLO-offset pinhole, and OCT methods were also compared. Full-factorial repeated-measures (subjects) mixed linear models were applied to the cone density, packing geometry, and inner segment diameter data, measured in SLO images, to evaluate the effects of group, eccentricity (4.5°, 9°, 13.5°, 18°), and aperture (confocal, offset). These were followed by Bonferroni-adjusted pairwise multiple comparison tests. Cone density, measured in the OCT, was evaluated using an additional mixed linear model with the same factors. A final mixed linear model, with an additional factor, layer (postreceptor, photoreceptor), was used to evaluate retinal thickness. The aforementioned analyses were all conducted in IBM SPSS Statistics 22 (SPSS; IBM, Chicago, IL, USA). Scanning light ophthalmoscopy and OCT cone counts were compared, using orthogonal regression, in Prism 6 (GraphPad Software, Inc., La Jolla, CA, USA). For all tests, the level of significance, α, was set at 0.05.
