Pigmented paravenous retinochoroidal atrophy (PPRCA) is a rare variant of retinochoroidal atrophy (RCA) characterized by bilateral pigment accumulation along the retinal veins and RCA.[1] The disease etiology remains unknown. Majority of the cases are sporadic but some are hereditary in nature.[2]


  Case Top


A 24-year-old female presented with complaint of diminution of vision in both eyes (OU) for 1 year, with no past history of inflammation, trauma, or nyctalopia and no family history of retinal disorders. Best-corrected visual acuity was 6/6p OU. Biomicroscopic examination of anterior segment was unremarkable OU. Fundus examination showed pigment clumps along the retinal vascular arcade with chorioretinal atrophy extending from the disc up to the equator with no involvement of the macula OU [Figure 1]a and [Figure 1]b.

Complete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reactive protein, and random blood sugar levels were within normal limits. Antinuclear antibody (ANA) test was negative and venereal disease research laboratory (VDRL) test was nonreactive. OU fundus autofluorescence showed crescentic area of hyperfluorescence adjacent to area of chorioretinal atrophy [Figure 1]c and [Figure 1]d. Full-field analysis showed peripheral field constriction OU [Figure 2]a and [Figure 2]b. OCT revealed retinal thinning OU [Figure 2]c and [Figure 2]d. ERG showed reduced photopic and scotopic responses OU [Figure 2]e.

  Discussion Top


Brown first reported a case of PPRCA in 1937 and termed it as retinochoroiditis radiata.[3] In PPRCA, the retinal pigment epithelium (RPE) damage leads to atrophy of the underlying choroid.[4] It is usually bilaterally symmetric but unilateral cases have also been reported.[5] The etiology remains unknown but mutations of CRB1 (crumbs homolog-1) gene have been implicated in its pathogenesis.[6] Patients usually are asymptomatic. In most cases, visual field may be normal, but some may have scotomas.[1] Fundus shows typical and characteristic pigment accumulation with RCA. Unaffected retina appears normal. Macula may be involved in some cases.[1] The differential diagnoses include chorioretinal degeneration and inflammatory diseases that cause chorioretinal atrophy. Yanagi et al. showed that the disease remains stationary in younger patients and slowly progress in older subjects.[7] Currently, no specific treatment modality is available for PPRCA. This photo essay highlights the salient diagnostic features in macular-sparing bilateral PPRCA in a young female.
