2 Supplemental Figure 1: High-resolution AO images of the cone mosaics in Figure 5 in normal control subjects (NCS), carriers of choroideremia (CAR) and choroideremia patients (CHM) showing the locations of each cone determined by direct counting and used for measurements of cone density. Cones were identified by author JM through a semi-automated custom Matlab 26, 27 program. Cone densities are shown for each image, and all densities measured fell within the previously reported normal range. Manual cone identification still leaves room for error through misidentifying or missed cones. This underscores the need for well-designed studies to test the repeatability, reliability, and variability of cone analysis with multiple observers and for more accurate, automated cone identification programs to alleviate the need for manual intervention. 2

3 Supplemental Figure 2: High-resolution AO images of the cone mosaic at approximately 0.5 mm along each meridian in choroideremia patients (CHM). Cone densities for each of the images in the two left columns fell within the previously reported normal range (Supplemental Figure 3). 32 Cone densities for each of the images in the two right columns fell below the previously reported normal range. 32 Scale bar 20 um. 3

Supplemental Figure 4: IR and OCT images from the left eye of symptomatic carrier 13132 showing large regions of RPE atrophy in the macula, including the foveal region.

5 Supplemental Figure 4: IR and OCT images from the left eye of symptomatic carrier showing large regions of RPE atrophy in the macula, including the foveal region. The atrophic border exhibits the classic scalloped edges characteristic of choroideremia. OCT shows loss of outer retinal layers in regions of atrophy, thinned RPE and indistinguishable interdigitation layer 5

6 in regions of relatively intact retina, abrupt borders at the edge of atrophy, interlaminar bridges, and outer retinal tubulation. Supplemental video 1: High resolution AOSLO images recorded at various focus levels in patient where bubble-like features are found adjacent to the centrally intact retina. This is the same location as shown in Figure 10 patient By adjusting the focus of the AO system, the bubble-like features came into best focus approximately 0.4D posterior to the plane of best focus for the cone photoreceptors. This image series was obtained using a custom built AOSLO as previously described. 40 The OCT for in Figure 10 shows that the bubble-like features co-locate with the hypo-reflective space in the en face translational directions; this through focus video this gives further evidence that the bubble-like features also co-locate with the hypo-reflective space in the choroid in depth.
