Background: To describe a unique case of pigmented paravenous retinochoroidal atrophy that developed several years after Vogt-Koyanagi-Harada disease.
Case Presentation: A 28-year-old woman presented with gradual vision loss in both eyes and nyctalopia for 2 years. Past medical history was relevant for Vogt-Koyanagi-Harada disease since the age of 19 and positive HLA-DR4. Funduscopic examination revealed perivascular pigmentary clumping and atrophic changes radiating from the optic disks. Spectral domain optical coherence tomography through the macula demonstrated perifoveal outer retinal layers loss with cystic degeneration. Fundus autofluorescence showed zonal areas of hypoautofluorescence corresponding to the areas of atrophy. Full-field electroretinogram identified mildly reduced scotopic and photopic responses. The patient was diagnosed with pigmented paravenous retinochoroidal atrophy.
Conclusions: Pigmented paravenous retinochoroidal atrophy may be acquired after Vogt-Koyanagi-Harada disease. Pathogenesis of pigmented paravenous retinochoroidal atrophy may involve inflammatory-related precursors on a background of genetic predisposition.

Introduction: Concomitant manifestation of PPRCA in one eye and RP-like retinopathy in the fellow eye is a rare clinical entity, with limited published descriptions to date. The aim of this study is to describe comprehensive clinical evaluations and long-term follow-up of three patients affected by this clinical picture.
Methods: Three patients with concurrent PPRCA and RP-like retinopathy were prospectively re-evaluated and comprehensive assessments were performed.

Article Synopsis
- The hexokinase 1 (HK1) gene mutation E874K has been identified as the cause of autosomal dominant retinitis pigmentosa (RP) 79, primarily in nonsyndromic cases.
- Two Japanese patients were studied, both diagnosed with RP79 and showing a similar pigmented paravenous retinochoroidal atrophy (PPRCA) phenotype, despite being from different families.
- The use of ultra-widefield fundus imaging has proven essential in detecting PPRCA, suggesting that as this technology becomes more accessible, additional cases of RP79 may be identified more easily through targeted genetic testing like Sanger sequencing.
