Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
To investigate the clinical findings and natural course of patients with pigmented paravenous chorioretinal atrophy (PPCRA) using multimodal imaging. Retrospective, observational case series. We reviewed the records of consecutive patients diagnosed with PPCRA at a single center and assessed serial fundus photographs, fundus autofluorescence (FAF), and spectral-domain optical coherence tomography images. Electrophysiological findings and visual field analysis were also reviewed. The study included 50 eyes in 25 patients. The mean age of the population was 51.6 ± 14.6 years. Nine patients (36.0%) were asymptomatic and 9 (36.0%) complained of nyctalopia. We divided fundus appearance into one of 3 groups: paravenous (58.0%), focal (16.0%), and confluent (26.0%). Of the 50 eyes, macular involvement was present in 13 eyes (26.0%). Fifteen patients (60.0%) demonstrated a symmetric fundus appearance, whereas 10 (40.0%) had marked asymmetry. Eight eyes (16.0%) exhibited apparent changes in fundus findings, over a mean follow-up period of 8.8 years. FAF imaging was most sensitive to evaluate the extent of lesions. Sixteen eyes (44.4%) showed progressive visual field loss during the follow-up period. Most patients maintained stable vision, and 36 eyes (72.0%) had a final visual acuity of 20/50 or better. Nevertheless, some eyes with macular involvement experienced severe deterioration in vision. Electrophysiological data were variable, and interocular asymmetry was common (45.8%). PPCRA can present with a more variable expressivity than previously described. Multimodal imaging can provide insights into its clinical characteristics to facilitate the diagnosis, classification, and follow-up of these patients.
