The patient also had a history of post-axial polydactyly in both feet (Figure 1).
Color fundus photography and autofluorescence showing Retinitis Pigmentosa changes. (A) Right eye, there is a "salt-and-pepper" appearance surrounding the macula, which extends towards the nasal mid-periphery. There is bone-spicule RPE hyperplasia, predominantly present in the nasal mid-periphery, and paravenous RPE hyperplasia. Arteriolar attenuation is also evident in all quadrants. (B) Left eye, same findings as the right eye. (C) Right eye, increased macular autofluorescence surrounded by a ring of granular hypoautofluorescence extending towards the mid-periphery surrounded by an additional zone of hyperautofluorescence. (D) Left eye, same findings as the right eye.

Infrared fundus photography (Optos, Inc.) showed a "salt-and-pepper" appearance surrounding the macula, bone-spicule retinal pigment epithelium (RPE) hyperplasia, paravenous RPE hyperplasia, and arteriolar attenuation OU (Figure 2A and B). Fundus autofluorescence showed macular autofluorescence with a surrounding granular hypoautofluorescence and an additional hyperautofluorescent zone OU (Figure 2C and D).
