Presentation
Pigmented paravenous retinochoroidal atrophy is an uncommon fundus disorder with a striking clinical presentation. [ncbi.nlm.nih.gov]
In the present case the visual acuity at presentation was poor caused by the macular involvement. There was no evidence of ocular inflammation. [ojoonline.org]

Entire Body System
- Asymptomatic
The maculas are spared of clinically observable abnormalities, and the vast majority of patients with this disorder are asymptomatic. [ncbi.nlm.nih.gov]
[…] commonly bilateral and symmetric retinal disease characterized by non-progressive or slowly progressive chorioretinal atrophy, peripapillary pigmentary changes and accumulation of ''bone-corpuscle'' pigmentation along the retinal veins and which is usually asymptomatic [orpha.net]
These patients are often asymptomatic, but with careful testing, scotomas corresponding to the areas of degeneration can be identified. Typically, the ERG is minimally reduced and disease is thought to be, at most, slowly progressive. [aibolita.com]
- Pallor
Note the pallor of the optic nerve, the vascular attenuation, atrophy of the pigment epithelium, and bone-spicules. Reproduced from Weleber, R. G., Butler, N. S., Murphey, W. H., Sheffield, V. C., and Stone, E. M. (1997). [aibolita.com]
Figure 1: Fundus photograph of the right eye showing waxy pallor of the disc, attenuated arterioles, and bony spicule pigmentation characteristic of retinitis pigmentosa (a). [ijo.in]
Fundus examination of the right eye showed clear ocular media and a normal optic disc without pallor. There was no vascular attenuation (Figure 1 and 2). [westcoastretina.com]
Macular displacement Macular halo Macular infarction Macular pigment deposit Macular subretinal fibrosis Macular traction syndrome Nerve fiber layer infarct Neurocutaneous syndrome Noncystic peripheral retinal tuft On examination - retinal pigmentation Pallor [icd9data.com]
The classic clinical triad of RP is arteriolar attenuation, retinal pigmentary changes (could be either hypopigmentation and/or hyperpigmentation in form of bone-spicule and pigment clumpings), and waxy disc pallor. [picuki.com]
Skin
- Alopecia
PPCA was first described in 1937 in a 47 year old man with alopecia areata whose fundus was incidentally noted to have the increased pigmentation along peripheral veins associated with chorioretinal atrophy. 1 The appearance was termed retinochoroiditis [westcoastretina.com]
The initial case was a 47 year old male with past exposure of tuberculosis (multiple family members) was admitted for alopecia areata. [eyewiki.org]

Eyes
- Retinal Pigmentation
Funduscopic examination revealed bone-spicule pigmentation and choroidal and retinal pigment epithelium atrophy along the vascular arcades, with macular involvement in right eye. [ncbi.nlm.nih.gov]
Keywords Public Health Genetic Study Retinal Pigment Epithelium Retinal Pigment Pigment Epithelium These keywords were added by machine and not by the authors. [link.springer.com]
- Night Blindness
The left eye of the same patient revealed typical PPRCA phenotype, with no night blindness, normal field, and normal ERG. RP and PPRCA phenotypes are part of the same spectrum of genetic disorder. [ncbi.nlm.nih.gov]
As a consequence, by the time the patient recognizes the symptom of night blindness, a reduction in cone sensitivity can be significant. [institut-vision.org]
However, unlike this case, loss of visual acuity and photopsia within the scotomata are common ocular symptoms associated with AZOOR patients, and night blindness and progressive visual field loss are observed in RP patients, respectively. [benthamopen.com]
- Blurred Vision
The majority of patients are asymptomatic at presentation or have mild blurred vision. The exception is patients with macular involvement, where vision can be severely reduced on presentation. [eyewiki.org]
Psychiatrical
- Suggestibility
Our patients, and the preponderance of males in previously reported cases of this disease, suggest the possibility of Y-chromosome mediated male-to-male transmission. [ncbi.nlm.nih.gov]
Neurologic
- Irritability
Mechanical centurion syndrome A 73-year-old woman with epiphora and ocular irritation resistant to medical treatment. The lacrimal pathway was permeable and there was no eyelid malposition. [infona.pl]
Workup
Systemic workup revealed QuantiFERON-gold positive. This is the first report of unilateral PPRCA secondary to presumed ocular tuberculosis. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:345-349.]. [ncbi.nlm.nih.gov]
Results of laboratory studies, including a vasculitis workup, were within normal limits. A tuberculin skin testing result was 20 mm, erythrocyte sedimentation rate was 23 mm/hr, and a Quantiferon TB gold test (Qiagen) result was normal. [retinatoday.com]
Laboratory test Laboratory studies should be aimed towards narrowing the differential diagnosis depending on the presentation and given the overlap with inflammatory degenerative diseases a workup can include: comprehensive metabolic panel, complete and [eyewiki.org]
We referred the patient for a medical workup and asked her to return in six to eight weeks for close observation. The patient returned two years later with complaints of vision loss OS (20/100; OD remained 20/20). [reviewofoptometry.com]

Prognosis
The visual prognosis for patients with pigmented paravenous retinochoroidal atrophy is quite good. [ncbi.nlm.nih.gov]
Prognosis - this condition recurs over months and frequent foveal involvement gives rise to a relatively poor prognosis. Multiple evanescent white dot syndrome (MEWDS) Nature - uncommon, idiopathic and self-limiting condition. [patient.info]
Prognosis Patients with PPRCA have good visual prognosis with slowly progressive disease. In patients without macular involvement, visual acuity is minimally adversely affected. [eyewiki.org]

WFAF may also be helpful in determining prognosis in patients with AMD, although this needs confirmation in larger trials (i.e., AREDS2). [reviewofophthalmology.com]
Etiology
Etiology The etiology of PPRCA remains unknown with a presumed initial inflammatory insult that leads to the slow developmental of the retinal findings. [eyewiki.org]
The etiology in this case could be inflammatory, infectious, or both. To the best of our knowledge after an extensive literature search, PPCRA with vasculitis has not been previously reported. [retinatoday.com]
Although earlier reports have suggested a possible post-inflammatory etiology such as tuberculosis, rubeola and syphilis as possible causes, a definite etiology remains elusive. [2] Typically, bone corpuscle pigmentation is seen along the distribution [ojoonline.org]
The cause of the condition may be unknown or idiopathic, although a dysgenetic, degenerative, hereditary etiology or even an inflammatory cause has been hypothesized. [ingentaconnect.com]
2013/61/10/586/121083 PPCRA is an uncommon, asymptomatic, slowly progressive disease of unknown etiology, although some authors have attributed it to be the sequela of ocular inflammation. [ijo.in]

Prevention
Prevention the secondary degeneration of cones in RP represents a very promising approach. This because such a therapy could be applied in a wide range of mutations expressed in rods, and even at late stages of the disease. [institut-vision.org]
