GL, glaucoma; RP, retinitis pigmentosa; HC, control participants; MD, Visual field mean deviation as measured with standard automated perimetry (SAP); na, not available.
1Proportion of central fixations within a fixation window of 2° radius as determined with a fundus-controlled perimeter (see section “Materials and Methods.”).
2RP participant with secondary glaucoma; visual field defects are predominantly driven by the primary disease, i.e., RP, consequently, RP2 is classified as RP.
