Association of Circulating Antiretinal Antibodies With Clinical Outcomes in Retinitis Pigmentosa. Invest Ophthalmol Vis Sci 2023; 64:13.

Abstract
Purpose To determine if circulating antiretinal antibodies (ARAs) differ between patients affected by retinitis pigmentosa (RP) and control participants and to assess whether ARAs are associated with clinical outcomes in patients with RP. Methods Cross-sectional study involving a group of patients clinically diagnosed with RP and a control group of healthy participants. Serum autoantibodies against enolase, heat shock protein 70 (HSP70), and carbonic anhydrase II (CAII) were tested in all participants using Jess capillary Western blot. We compared ARA prevalence between the RP and control groups and investigated the association of serum ARA positivity with macular edema and vitreomacular disorders in patients affected by RP. Results Thirty-six patients affected by RP and a control group of 39 healthy individuals were included. Overall, at least one ARA positivity was detected in 89% and 80% of participants in the RP and control groups, respectively. We observed a similar prevalence of anti-CAII and anti-enolase ARA between patients and controls (P = 0.87 and P = 0.35, respectively). Sera from patients with RP tested positive for anti-HSP70 ARAs more frequently than those from controls (53% vs. 36%), albeit without reaching statistical significance (P = 0.29). Among the 72 eyes with RP, 25% presented with macular edema (most often bilateral) and 33% with epiretinal membrane and/or lamellar macular hole. None of the three ARAs was associated with an increased risk of any macular complications in eyes affected by RP (all P > 0.05). Conclusions The prevalence of circulating ARAs against enolase, HSP70, and CAII is similar between patients affected by RP and healthy individuals. Our results provide evidence against the association of ARAs with macular edema and vitreomacular interface disorders in RP.

Abstract
PURPOSE To report a case of Pigmented Paravenous Chorioretinal Atrophy (PPCRA) associated with a novel RPGRIP1 dominant variant. METHODS Case report. The patient underwent multimodal retinal imaging, including spectral-domain optical coherence tomography (OCT), OCT Angiography (OCTA), blue-light autofluorescence (BAF), and ultra-widefield pseudocolor retinography and autofluorescence. Genetic testing was performed using next-generation sequencing. RESULTS A 67-year-old male presented with a clinical suspicion of retinitis pigmentosa. His best-corrected visual acuity was 20/32 in the right eye and 20/200 in the left eye. On fundus examination, paravenous pigment clumping and chorioretinal atrophy were seen bilaterally, matching confluent hypoautofluorescent areas departing from the optic disc. This clinical presentation suggested a case of PPCRA. Genetic testing found a heterozygous deletion of nucleotide 631 (c.631del) in the RPGRIP1 gene, a frameshift variant that generates a premature stop codon (p.Ser211Valfs*64) and therefore results in a truncated or absent protein product. The variant was regarded as likely pathogenic (class IV). CONCLUSION In this report, we describe a case of PPCRA in association with a novel, likely pathogenic c.631del, p.Ser211Valfs*64 variant in RPGRIP1, a gene that has been associated with Leber congenital amaurosis and cone-rod dystrophy. Our case expands the spectrum of genes associated with PPCRA and prompts further studies to ascertain the molecular etiopathogenesis of this disease.

Posterior vitreous cortex hyalocytes visualization in asymmetric pigmented paravenous chorioretinal atrophy (PPCRA) using en face OCT. Am J Ophthalmol Case Rep 2023; 30:101846. [PMID: 37114189 PMCID: PMC10126849 DOI: 10.1016/j.ajoc.2023.101846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 03/26/2023] [Accepted: 04/09/2023] [Indexed: 04/29/2023] Open
Abstract
Purpose Pigmented paravenous chorioretinal atrophy (PPCRA) is a rare retinal disease with inflammatory or infectious associations affecting the retinal pigment epithelium (RPE) and choriocapillaris. While the clinical manifestations and imaging findings are well-documented in the literature, no reports exist describing potential biomarkers of intraocular inflammation or ischemia in this condition, such as the presence of posterior vitreous cortex hyalocytes. Observations We report a case of a 26-year-old female who presented with progressive peripheral vision loss in both eyes over one year. Dilated fundus examination revealed bilateral, asymmetric bone-spicule pigmentary changes along the retinal veins, which appeared more advanced in the left eye. Optical coherence tomography (OCT) revealed the presence of numerous hyalocytes in both eyes 3 μm anterior to the inner limiting membrane (ILM). The morphology of the hyalocytes differed between the two eyes, suggesting different levels of activation related to the stage of the disease. Specifically, the left eye, with more advanced disease, exhibited hyalocytes with multiple elongated processes consistent with a quiescent state, whereas the right eye, with the less advanced disease state, exhibited amoeboid-appearing hyalocytes suggestive of more active inflammation. Conclusions This case illustrates how hyalocyte morphology may reflect the underlying activity of an indolent retinal degeneration and provide a useful biomarker of disease progression.

Abstract
BACKGROUND Pigmented paravenous retinochoroidal atrophy (PPRCA) is an uncommon fundus disease characterized by perivenous aggregations of pigment clumps and retinochoroidal atrophy distributed along the retinal veins. We report a Chinese female case of unilateral PPRCA with acute angle-closure glaucoma (AACG). CASE PRESENTATION A 50-year-old Chinese female presented with vision loss and elevated intraocular pressure (IOP) in the right eye and then underwent trabeculectomy. She referred to our clinic for further evaluation and treatment. The funduscopic examination revealed grayish retinochoroidal atrophy and osteocyte-like pigment clumping lesions along the retinal veins and peripapillary preretinal hemorrhage in the right eye. The patient also presented with AACG in the same eye on the basis of past medical history of acute attack, shallow anterior chamber depth (ACD), narrow angle showed by ultrasound biomicroscopy (UBM) and glaucomatous neuropathy identified by optical coherence tomography (OCT). Other examinations like fluorescein fundus angiography (FFA), electroretinogram (ERG) and electrooculography (EOG) all confirmed the aforementioned diagnose. CONCLUSION PPRCA is a rare disease, uncommon in females and symmetrical in both eyes. We present a rare case of unilateral PPRCA accompanied with AACG.

Abstract
The aim of this case report is to present the multimodal imaging characteristics of pigmented paravenous retinochoroidal atrophy (PPRCA) in a pediatric patient with cystoid macular edema (CME). A 7-year-old girl was admitted to our clinic with complaints of mild blurred vision and poor night vision. Best corrected visual acuity was 10/10 in both eyes. Fundus examination showed atrophic areas around the optic nerve and along the retinal vessels in both eyes. A few small dot-shaped paravenous pigmentations were observed in the mid-peripheral retina. Fundus autofluorescence was consistent with PPRCA. Spectral-domain optical coherence tomography (OCT) revealed the presence of CME and loss of the outer retinal layers outside the macula, with intact retinal layers in the macula. OCT angiography revealed normal choriocapillaris vasculature and flow. The patient was followed up for 6 months but showed no change in CME or clinical appearance. CME without ocular inflammation is an unusual finding of PPRCA and may suggest the involvement of chronic or latent inflammation in the etiology of PPRCA.

Abstract
PURPOSE To analyze the retino-choroidal vascular characteristics of patients affected by pigmented paravenous chorio-retinal atrophy by means of optical coherence tomography (OCT) angiography. METHODS This study was designed as an observational, cross-sectional case series. Multimodal imaging included fundus autofluorescence, structural OCT, and OCT angiography. The quantitative OCT angiography analyses included the calculation of the vessel density and choriocapillaris porosity. RESULTS Overall, 12 patients (24 eyes) affected by pigmented paravenous chorio-retinal atrophy were recruited. Structural OCT of the areas involved by pigmented paravenous chorio-retinal atrophy as visualized on the fundus autofluorescence showed a complete ellipsoid zone and external limiting membrane absence, with thinning of ganglion cell complex, outer nuclear layer, and outer plexiform layer, but associated with the optical partial preservation of the retinal pigment epithelium. Optical coherence tomography angiography quantitative assessment of the retinal regions affected by PPRCA, as visualized by fundus autofluorescence, was characterized by normal vessel density at the level of superficial capillary plexus but significantly altered vessel density of deep capillary plexus and choriocapillaris, with higher choriocapillaris porosity. The presence of macular atrophy was significantly correlated with worse deep capillary plexus and choriocapillaris vessel density values. Furthermore, a statistically significant correlation between the fundus autofluorescence patterns and the retinal vascular status was found. CONCLUSION Optical coherence tomography angiography quantitative analyses in pigmented paravenous chorio-retinal atrophy demonstrate a specific impairment at the level of the deep capillary plexus, which could in turn bring about a thinning of ganglion cell complex and outer nuclear layer. The alterations at the level of the choriocapillaris and the choroid, in general, could then represent a secondary effect.

Abstract
Background and Objectives: Pigmented paravenous retinochoroidal atrophy (PPRCA) is a rare disease with bilateral retinal pigment epithelium and choroidal atrophy. We present a case of PPRCA using multimodal imaging studies. Case summary: A 61-year-old female was referred to our department for floaters. Funduscopic examination revealed pigment clumps and grayish lesions along the retinal vein and the peripheral area, bilaterally. She did not have nyctalopia or any other visual symptoms including visual loss. She was diagnosed with pigmented paravenous retinochoroidal atrophy based on the typical findings of fundus. The findings of wide fluorescein angiography (FA), wide indocyanine green angiography (ICGA), fundus autofluorescence (FAF), spectral domain-optical coherence tomography (SD-OCT), optical coherence tomography angiography (OCTA), the visual field (VF) and an electroretinogram (ERG) could help us to confirm the diagnosis. The patient did not have any specific treatment for PPRCA in our study and there was no change in visual acuity and multimodal imaging of both eyes over one year. Conclusions: We report a case of PPRCA and the multimodal imaging of this patient. PPRCA is very rare disease and sometimes it is easy to get confused with other diseases such as retinitis pigmentosa and vasculitis when it comes to diagnosis. Multimodal imaging features of PPRCA will improve our understanding, diagnosis and prediction of the prognosis of this disease.

Abstract
PURPOSE To investigate the clinical findings and natural course of patients with pigmented paravenous chorioretinal atrophy (PPCRA) using multimodal imaging. DESIGN Retrospective, observational case series. METHODS 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. RESULTS 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%). CONCLUSIONS 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.

Abstract
PURPOSE To demonstrate phenotypic discordance between a monozygotic twin pair, one of whom exhibited pigmented paravenous chorioretinal atrophy (PPCRA). METHODS A patient and his identical twin brother, attending Moorfields Eye Hospital, were reviewed. Clinical assessment included visual acuity and color vision testing, fundus imaging including autofluorescence, spectral-domain optical coherence tomography and static perimetry. In addition, the affected sibling underwent pattern and full field electroretinography (PERG and ERG) according to ISCEV standards. Zygosity testing was performed using short tandem repeat (STR) analysis. RESULTS The 48-year old proband was referred with abnormal visual fields and difficulty reading at near. Examination revealed 20/20 Snellen visual acuity bilaterally, normal colour vision and bilateral asymmetric outer retinal atrophy with intra-retinal pigment migration along the course of the retinal veins, consistent with PPCRA. The visual field defects were contiguous with the blind spot and mirrored the retinal involvement in both eyes. Pattern ERG showed mild macular dysfunction and full field ERG was within normal limits. Blood testing for common uveitic entities was non-contributory. The proband's twin brother's clinical assessment and retinal imaging showed no abnormality. Zygosity testing showed the twins to be identical for 24 short tandem repeat (STR) microsatellite markers, indicative of monozygosity. CONCLUSION Some cases of PPCRA, without an obvious inflammatory etiology, do not have a clear Mendelian inheritance pattern and may represent an acquired disorder.

Abstract
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.

Abstract
Background: Pigmented Paravenous Chorioretinal Atrophy (PPCRA) is a rare and predominantly sporadic form of chorioretinal atrophy. Ocular and systemic inflammation has been considered a possible etiology of PPCRA. In this report, we describe an unusual case of PPCRA in a child who was recently diagnosed with chronic granulomatous disease.Case description: A 4-year-old boy was referred for ophthalmic assessment after a seizure. Fundus examination revealed atrophic chorioretinal lesions typical of PPCRA. We had also referred this patient to a gastroenterologist for chronic abdominal pain and diarrhea. The patient was first diagnosed as a case of Crohn's disease, but in the setting of mesenteric lymphadenopathy, a workup for immune dysfunction was performed. Nitro-blue tetrazolium test (NBT) was negative, suggesting a chronic granulomatous disease, which was finally confirmed by genetic testing.Conclusion: The presentation of PPCRA has been sporadic in the majority of cases. Inflammatory and hereditary origins have been anecdotally cited. Our young patient showed concurrent presentation of inflammatory and hereditary origin of PPCRA. We suggest that a careful investigation of systemic inflammation should be done in children with suggestive extraocular symptoms in the setting of PPCRA.

Abstract
A 65-year-old man was referred to our department with complaints of blurred vision in the left eye. Funduscopic examination revealed areas of retinochoroidal atrophy along the retinal veins bilaterally and bone spicule pigmentation along the nasal and superior temporal venous branches, as well as macular oedema in the left eye. Fluorescein angiography, visual field test, optical coherence tomography and electrophysiological examination were performed, and results were compatible with the diagnosis of pigmented paravenous retinochoroidal atrophy (PPRCA). Treatment with topical dorzolamide and intravitreal bevacizumab in the left eye resulted in poor anatomical and visual response. There is scarce documentation of macular involvement with non-inflammatory unilateral cystoid macular oedema in PPRCA in the literature. Further investigation is required to elucidate the pathogenesis of PPRCA and to properly manage these patients.

Novel clinical findings in autosomal recessive NR2E3-related retinal dystrophy. Graefes Arch Clin Exp Ophthalmol 2018; 257:9-22. [PMID: 30324420 DOI: 10.1007/s00417-018-4161-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2018] [Revised: 10/01/2018] [Accepted: 10/03/2018] [Indexed: 02/07/2023] Open
Abstract
PURPOSE To evaluate the clinical phenotype of autosomal recessive NR2E3-related retinal dystrophy. METHODS We retrospectively studied 11 patients carrying out at least 2 NR2E3 mutations; they had undergone comprehensive ophthalmological examination, fundus photography, optical coherence tomography, electrophysiological testing, and visual field at the Regional Reference Center for Hereditary Retinal Degenerations of the Eye Clinic in Florence. RESULTS Five females and six males with a diagnosis of NR2E3-related retinal dystrophy were included in the study. All patients complained of nyctalopia. Visual acuity ranged from 0.00 logMAR to hand motion. Two patients presented bull's eye maculopathy, and one of these was characterized by a triple hyper-autofluorescent ring at the fundus autofluorescence examination. Three patients showed small yellowish dots and spots at the mid-periphery. One patient was characterized by widespread subretinal drusenoid deposits (SDD) at the posterior pole. Four patients showed vitreous abnormalities. Optical coherence tomography (OCT) examinations detected variable degrees of abnormal retinal lamination and schitic changes. Seven patients were compound heterozygous and four were homozygous for mutations in NR2E3. CONCLUSIONS Our study confirmed high variable phenotype in autosomal recessive NR2E3-related retinal dystrophy. Bull's eye maculopathy, subretinal drusenoid deposits, and foveal hypoplasia represent novel clinical findings in NR2E3-related retinal dystrophy. Macular involvement was detectable in all the patients, and the abnormal foveal avascular zone (FAZ) supports the role of NR2E3 in retinal development.
