[PMID: 38836943 DOI: 10.1007/s00417-024-06534-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 04/09/2024] [Accepted: 05/23/2024] [Indexed: 06/06/2024] Open
Abstract
PURPOSE To investigate the relationships between macular complications and causative genes frequently found in Japanese patients with retinitis pigmentosa (RP). METHODS In the retrospective and observational study, we analyzed the data of 75 patients with RP (EYS-RP: 42 patients; USH2A-RP: 19 patients; RHO-RP: 14 patients) who were followed-up at Kyushu University Hospital and whose causative genes had been identified. Macular complications including epiretinal membrane (ERM), macular edema (ME), and macular hole (MH) were evaluated using optical coherence tomography and fundus photography. Main outcome was the proportion of macular complications. RESULTS The proportion of ERM was 35.7% in the EYS group, 10.5% in the USH2A group and 14.3% in the RHO group. The proportion of ME was 7.1% in the EYS group, 5.3% in the USH2A group and 14.3% in the RHO group, and that of MH was 2.4% in the EYS group, 5.3% in the USH2A group and 0% in the RHO group. In the EYS group, the proportion of ERM was relatively higher (p = 0.06), and the presence of EYS was significantly associated with a higher age- and sex-adjusted OR for ERM (OR = 5.67, 95% CI = 1.59-25.20). There was no significant difference in the proportion of MH or ME among causative genes. CONCLUSIONS EYS causative gene may be associated with higher rate of ERM complication in RP.

Sci Rep 2023; 13:22040.

Abstract
In retinitis pigmentosa (RP), photoreceptor degeneration leads to progressive visual field loss and visual impairment. Several therapeutic trials are ongoing aiming to establish effective treatments. Although functional evaluations are commonly used in clinical trials, residual ellipsoid zone (EZ) measurement on optical coherence tomography has been shown to be more sensitive to detect disease progression. Establishment of sensitive outcome measurement is essential to develop new therapeutic strategies. In the current study, we evaluated the progression rates of the disease in 76 eyes of 76 patients with RP, using the residual EZ length, ring-shaped macular hyperautofluorescent (AF), and visual field. Decrease rates measured by the residual EZ area and by the hyper-AF ring area were strongly positively correlated (P < 0.0001, r = 0.71). The reduction rates of the residual EZ length and hyper-AF ring radius were constant regardless of their baseline measurements. Faster annual reduction rates of the hyper-AF ring area or radius were significantly correlated with faster visual field progression (P = 0.03, r = 0.25 and P = 0.004, r = 0.33, respectively). These findings support the usage of morphological measurements such as EZ or hyper-AF ring measurements as outcome measurement for future clinical trials for RP.

Abstract
Mutations in the EYS gene are one of the major causes of autosomal recessive retinitis pigmentosa. EYS-retinopathy presents a severe clinical phenotype, and patients currently have no therapeutic options. The progress in personalised medicine and gene and cell therapies hold promise for treating this degenerative disease. However, lack of understanding and incomplete comprehension of disease's mechanism and the role of EYS in the healthy retina are critical limitations for the translation of current technical advances into real therapeutic possibilities. This review recapitulates the present knowledge about EYS-retinopathies, their clinical presentations and proposed genotype–phenotype correlations. Molecular details of the gene and the protein, mainly based on animal model data, are analysed. The proposed cellular localisation and roles of this large multi-domain protein are detailed. Future therapeutic approaches for EYS-retinopathies are discussed.

RP1L1 and inherited photoreceptor disease: A review. Surv Ophthalmol 2020; 65:725-739.

Abstract
Retinitis pigmentosa 1-like 1 (RP1L1) is a component of the photoreceptor cilium. Pathogenic variants in RP1L1 lead to photoreceptor disease, suggesting an important role for RP1L1 in photoreceptor biology, though its exact function is unknown. To date, RP1L1 variants have been associated with occult macular dystrophy (a cone degeneration) and retinitis pigmentosa (a rod disease). Here, we summarize reported RP1L1-associated photoreceptor conditions and disease-causing RP1L1 variants. We also discuss novel associations between RP1L1 and additional photoreceptor conditions-besides occult macular dystrophy and retinitis pigmentosa-and fit RP1L1 into the broader scope of photoreceptor disease. RP1L1 appears to have a complex relationship with other photoreceptor proteins and may modify disease phenotype. Ultimately, further exploration of the relationship between RP1L1, other cilium components, and their impact on photoreceptor health is needed.

Abstract
PURPOSE To assess the long-term clinical course of 2 patients with PRPF31-related retinitis pigmentosa (RP). PATIENTS AND METHODS We clinically examined 2 unrelated patients with RP and collected peripheral blood samples from them. Ophthalmic examinations, including best-corrected visual acuity measurements, Goldmann perimetry, full-field electroretinography, fundus autofluorescence imaging, and optical coherence tomography, were also performed. The visual acuity and visual field were continuously monitored. To identify the causative mutations, 74 genes known to cause RP or Leber congenital amaurosis were examined via targeted next-generation sequencing. RESULTS The clinical courses of both patients were similar. The onset of nyctalopia occurred in the first decade. Fundus examination showed typical RP. Although the patients' visual acuity was relatively preserved even into the fourth decade, the visual field area exhibited rapid deterioration in the mid-teens, with severe concentric constriction in the third decade. Mutation analysis revealed PRPF31 mutations as the cause for autosomal dominant RP in both patients. CONCLUSIONS To the best of our knowledge, few reports of long-term observations pertaining to patients with PRPF31-related RP have been published. The findings reported herein, especially those relating to the progressive degeneration of the visual field, may ultimately play a role in the provision of high-quality counseling for patients with this condition.

Abstract
PURPOSE EYS and USH2A are the most common causative genes for retinitis pigmentosa (RP) in Japan. We determined the clinical outcomes for USH2A-related non-syndromic RP or Usher syndrome type II (USH2). METHODS Two non-syndromic RP and 11 USH2 patients with previously identified USH2A mutations were included. Their complete history and medical records were collected using standard procedures. Visual fields and acuity were compared with those of patients with EYS mutations. Clinical analyses were based on ophthalmic and otolaryngologic examinations. RESULTS In all patients, the fundus displayed changes typical of RP. Most patients showed relatively well-preserved visual acuity in their thirties or forties, with rapid deterioration in their fifties. Concentric constriction started in the twenties or thirties, and no effective residual visual field was observed after the fifties. CONCLUSIONS The visual outcome for non-syndromic RP or USH2 patients with USH2A mutations is consistent with that for RP patients with EYS mutations.

Inner segment ellipsoid band length is a prognostic factor in retinitis pigmentosa associated with EYS mutations: 5-year observation of retinal structure. Eye (Lond) 2016; 30:1588-1592.

Abstract
PurposeTo evaluate whether the length of the inner segment ellipsoid (ISe) band can be used as a prognostic factor for disease course in retinitis pigmentosa (RP) patients with EYS mutations by observation over a period of 5 years.MethodsTwelve RP patients with EYS mutations were studied. The horizontal and vertical ISe length of the right eye was manually measured at five time points annually, using spectral domain optical coherence tomography. A regression line through the five points from baseline to the final measurement was drawn and the ratio of the length (%) at each point to the baseline length was calculated; the slope was defined as the rate of ISe shortening (%/year). The correlation between the rate of ISe shortening and age, visual acuity, and mean deviation (MD) value were evaluated. The intraclass correlation coefficient (ICC) for the measurements was calculated.ResultsThe mean rate of ISe shortening was -4.65±2.89% per year and the decline was statistically significant. The rate of shortening was significantly negatively correlated with the baseline length (P=0.046, r=0.58), but not with the baseline age, visual acuity, and MD value. The ICC (2, 1) was 0.999.ConclusionsISe of all RP patients with EYS mutations shortened during the 5 years of annual observation. The measurement of the length of ISe is a simple and convenient method with high repeatability, and the length is a sensitive prognostic factor for the rate of ISe shortening in RP patients with EYS mutations.
