Early autofluorescence findings of relentless placoid chorioretinitis

摘要

Relentless placoid chorioretinitis is characterized by retinal lesions similar in clinical and angiographic appearance to acute posterior multifocal placoid pigment epitheliopathy and serpiginous choroidopathy but different in its widespread distribution, number of lesions, and rapidly progressive clinical course.A 27-year-old man came to our institution complaining of paracentral scotomas in both eyes. He had a history of flu-like syndrome during the previous 2 weeks. His best-corrected visual acuity was 20/20 in each eye. Fundus examination showed multiple yellow-whitish placoid areas at the posterior pole and in the midperipheral retina of both eyes, similar to those seen in acute posterior multifocal placoid pigment epitheliopathy. Fundus auto-fluorescence showed a pattern with three concentric zones of different autofluorescence, which we described as "cockade pattern" because its aspect was similar to a cockade in shape and in the alternation of color bands. The first is a central round area of strong hypoautofluor-escence followed by a narrow hyperautofluorescence circular zone. These were follo.wed outwards by a faint wide hypoautofiuorescence ring (Figure 1, A-C and Figure 2A).
