Original Paper


We report the case of a 6-year-old girl with an unusual petaloid-pattern pigmentary retinopathy associated with nyctalopia and reduction of vision which had been invariably static over the past 5 years. We performed a comprehensive ophthalmic examination including fundoscopy, autofluorescent imaging, electroretinography and optical coherence tomography. There were diffuse retinal pigment epithelium (RPE) washout areas with blotches of pigment distributed in the pattern of a petal with marked chorioretinal atrophy and scar at the fovea. The arterial caliber was normal. Investigations ruled out intrauterine and neonatal infection. Systemically, she was healthy with normal intellect but with 3-month delayed milestones of development. She had used valproic acid for seizure disorder (without any organic central nervous system lesion) from 2–5 years of age. Electroretinography showed extinguished scotopic responses with slight reduction in cone responses. Optical coherence tomography showed a scar with attenuated RPE–choriocapillary complex at the macula. Her clinical profile did not fully match with any previously described pigmentary retinopathies except rod–cone dystrophy and choroidal dystrophy to a certain extent. The pigmentary retinopathy reported here is a combination of a petaloid pattern of pigmentary disturbance, stationary reduction of vision, nyctalopia, normal intellect and marginal delayed milestones. In the absence of such a description in the literature we named this disorder as petaloid-pattern pigmentary retinopathy.
