| Abstract |
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. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 September 2014.
All research outputs
#20,237,640
of 22,764,165 outputs
Outputs from International Ophthalmology
#657
of 1,032 outputs
Outputs of similar age
#266,727
of 308,640 outputs
Outputs of similar age from International Ophthalmology
#10
of 24 outputs
Altmetric has tracked 22,764,165 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,032 research outputs from this source. They receive a mean Attention Score of 2.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 308,640 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 24 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
