Progressive changes in short-wave fundus autofluorescence imaging and spectral domain optical coherence tomography scans of a patient with RPGR-mediated X-linked retinitis pigmentosa. Short-wave fundus autofluorescence (SW-FAF) images with a 30-degree field of view (a) during the first clinic visit of a patient with X-linked retinitis pigmentosa (XLRP) caused by the RPGR gene. The corresponding spectral domain optical coherence tomography (SD-OCT) scan is also shown (e). On the SW-FAF images, the area of the hyperautofluorescent ring is outlined in green (13.4 mm2), whereas the horizontal diameter (5057 µm) is indicated by the red line (b,d). On the SD-OCT scans, the ellipsoid zone (EZ) line width is also marked with a red line, measuring 4178 µm. On the follow-up visit 1.4 years later, the EZ line shortened to 3859 µm (f), while both the horizontal diameter and ring area on SW-FAF (d) decreased to 4668 µm and 11.8 mm2, respectively.
