Comet-tail lesions are small, round, white bodies seen commonly in the inferior midperiphery of the retina [Figure 1]a. These are frequently associated with a tail, which always points toward the optic disc. On red-free imaging, comet-tail lesion appears as a bright dot with a less bright tail [Figure 1]b. Optical coherence tomography reveals them as hyporeflective spaces covered by hyperreflective margin, which overlie retinal pigment epithelium [Figure 1]c. Comet-tail lesions are considered to be pathognomonic of pseudoxanthoma elasticum (PE) and may appear earlier than other changes of PE such as angioid streaks and Peau d'orange.[1],[2]
