Abstract
INTRODUCTION New insights on polypoidal choroidal vasculopathy (PCV) have shed light regarding its pathophysiology and associations. However, PCV characterization is still incomplete in Caucasians, which is due to presumed lower prevalence in this population. Features typically associated with AMD such as drusen, retinal pigmentary changes or atrophy are seen in PCV, as precursors and in the fellow eye. Pachychoroid spectrum, predisposing to PCV, also presents with chronic changes in the retinal pigment epithelium (RPE), such as drusen-like deposits (DLD), and in the choroid. The purpose of this study is to perform a multimodal imaging characterization of unaffected fellow eyes in a sample of Caucasian patients with unilateral PCV. METHODS Multicenter retrospective cohort study with a sample of 55 unaffected fellow eyes from patients diagnosed with unilateral PCV confirmed by indocyanine green angiography. The sample was characterized in the baseline by color fundus photography, spectral domain optical coherence tomography (SD-OCT), fluorescein angiography and indocyanine green angiography. Morphological characteristics of both the retina and the choroid were evaluated. The SD-OCT of the last follow-up visit was also evaluated in order to exclude evolution to PCV or choroidal neovascularization. All images captured underwent evaluation by two independent graders. Informed consent was obtained from all participants. RESULTS Fifty-five patients (median age, 74 ± 15 years) were included. After 15.5 ± 6.4 months of follow-up, only one developed disease (1.9%). Soft and/or hard drusen were present in 60% and pachydrusen in 23.6%. Pachychoroid signs were present in 47.2%, the double-layer sign in 36.4%, disruption of the RPE changes in 16.4% and RPE atrophy in 10.9%. ICGA revealed choroidal vascular dilation in 63.6% and punctiform hyperfluorescence in 52.7%. Branching vascular networks were identified in only 1.9% of cases. CONCLUSION The identification of pachychoroid signs in the OCT and ICGA were present in over half of the cases and the presence of the double-layer sign in more than a third provide crucial insights for enhanced characterization of this pathology and deeper understanding of its pathogenesis. These findings contribute significantly to the current knowledge, offering valuable markers to discern various phases of the pathology's progression.

Abstract
Advances in imaging have led to improved ability to characterize variations in clinical sub-phenotypes of macular neovascularization (MNV) in Age-related macular degeneration (AMD). Polypoidal choroidal vasculopathy (PCV) was initially described based on characteristic features observed in indocyanine green angiography (ICGA) and was thought to be a distinct entity from AMD. However, subsequent careful observations based on confocal scanning laser ophthalmoscopy-based ICGA, optical coherence tomography (OCT) and OCT angiography have led researchers to appreciate similarities between PCV lesion and type 1 MNV in typical neovascular AMD. Concurrently, clinical trials have shown that anti-VEGF monotherapy can achieve favourable visual outcome in the majority of eyes with PCV. These learnings have led to a shift in the way PCV is managed over the past decade. Recent studies have supported the use of non-ICGA based imaging modality to screen for PCV and the adoption of anti-VEGF monotherapy as initial therapy for PCV. A focus of recent research has been in the understanding of the role of choroidal alterations in the pathogenesis of PCV. The concept of pachychoroid in leading to outer retinal ischemia has garnered increasing support. Future research in this area should evaluate the potential of choroidal morphology in guiding personalized therapy in PCV.

[PMID: 38055121 PMCID: PMC10776525 DOI: 10.1007/s40123-023-00843-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 10/20/2023] [Indexed: 12/07/2023] Open
Abstract
The port delivery system (PDS) of anti-VEGF therapy provides continuous delivery of ranibizumab (RBZ). In October of 2021, the American Food and Drug Administration (FDA) approved the PDS with RBZ as a treatment option for neovascular age-related macular degeneration (nAMD). As the field of PDS with RBZ is progressing rapidly, this narrative review provides a much-needed overview of existing clinical trials as well as ongoing and upcoming trials investigating PDS with RBZ. The phase 2 LADDER trial reported that the mean time to first refill with RBZ PDS 100 mg/ml was 15.8 months (80% CI 12.1-20.6), and pharmacokinetic profiling revealed a sustained concentration of RBZ in serum and aqueous humor. Later, the phase 3 ARCHWAY trial reported that PDS with RBZ (100 mg/ml) refilled every 24 weeks was non-inferior to monthly intravitreal injection (IVI) with RBZ (0.5 mg) in patients with nAMD over 9 months and 2 years. However, patients with PDS had a higher rate of adverse events including vitreous hemorrhage and endophthalmitis. Patients indicate high treatment satisfaction with both PDS and IVI, but the lower number of treatments with PDS was reported as a preferred choice. Several ongoing and future clinical trials, of which details are discussed in this paper, are further exploring the potentials of PDS with RBZ. We conclude that the PDS provides continuous deliverance of RBZ and that clinical efficacy levels are non-inferior to IVI therapy for nAMD. Yet, a higher rate of adverse events remains a concerning detail for widespread implementation. Future studies are warranted to better understand which patients may benefit best from this treatment approach, if long-term efficacy can be sustained, and if safety of PDS can be further improved.

Anti-VEGF Treatment Strategies for 3 Subtypes of Neovascular Age-Related Macular Degeneration in a Clinical Setting: A Multicenter Cohort Study in Japan. Ophthalmol Retina 2023; 7:869-878. [PMID: 37295608 DOI: 10.1016/j.oret.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 06/01/2023] [Accepted: 06/01/2023] [Indexed: 06/12/2023]
Abstract
PURPOSE Neovascular age-related macular degeneration (nAMD) is classified into typical AMD (tAMD), polypoidal choroidal vasculopathy (PCV), and retinal angiomatous proliferation (RAP). This study investigated clinical features of the 3 subtypes and visual outcome associated with treatment regimens in a large cohort of patients with nAMD in a clinical setting. DESIGN Retrospective multicenter cohort study. PARTICIPANTS Five hundred patients with treatment-naive nAMD (268 tAMD, 200 PCV, and 32 RAP) initiated with anti-VEGF agents and followed for 1 year. METHODS Medical records were reviewed to extract demographic data, best-corrected visual acuity at baseline and 1 year after treatment initiation, spectral-domain OCT findings, baseline fellow eye condition, systemic factors, treatment strategies, and number of intravitreal injections in the first year. MAIN OUTCOME MEASURES Primary outcome measures were anti-VEGF treatment strategy (ranibizumab or aflibercept, anti-VEGF regimen, concomitant photodynamic therapy, drug switch), best-corrected visual acuity at 1 year, and factors associated with visual acuity. RESULTS Patients with RAP were significantly older, were more commonly women, and had more macular lesions in fellow eye than patients with tAMD and PCV. Smoking history and diabetes prevalence were not different among the 3 subtypes. Frequencies of subretinal fluid were higher and intraretinal fluid were lower in tAMD and PCV than in RAP, whereas serous pigment epithelial detachment and subretinal hemorrhage were higher in PCV than in tAMD and RAP. Choice of anti-VEGF agents and treatment regimens did not differ among 3 subtypes. The aflibercept-to-ranibizumab ratio was approximately 7:3. The mean number of injections in 1 year was 5.3 ± 2.4 in nAMD overall, which was significantly less in pro re nata (PRN) than in treat and extend (TAE) regardless of the anti-VEGF agent. Best-corrected visual acuity improved in all 3 subtypes, although it was not significant in patients with RAP. CONCLUSIONS This clinical study demonstrates that treatment regimens were similar in 3 subtypes and aflibercept was used in 70% of all patients. Approximately 5 injections were given in the first year regardless of the anti-VEGF agent, which was significantly less in PRN regimen than in TAE. Visual acuity improvement was observed after 1-year anti-VEGF therapy in all 3 subtypes, but was not significant in RAP.

Abstract
Background Neovascular age-related macular degeneration (nAMD) and its subtype, polypoidal choroidal vasculopathy (PCV), are common choroidal vasculopathies. Although they share many common clinical manifestations and treatment strategies, a lack of comprehensive analysis of these conditions means that it is difficult for researchers to further explore the common pathomechanisms of nAMD and PCV. The aim of this study was to characterize aqueous humor (AH) proteome alterations and identify a novel biomarker related to both nAMD and PCV. Methods Liquid Chromatography with tandem mass spectrometry (LC-MS/MS) was adopted to analyze the AH proteomes of nAMD, PCV and controls. The target protein was validated using the enzyme-linked immunosorbent assay (ELISA) and subjected to receiver operating characteristic (ROC) curve analysis. Results A total of 737 different proteins were identified in all the groups, of which 544 were quantifiable. The bioinformatics analysis suggested that immune response activation is the essential event in both nAMD and PCV. Serum amyloid A (SAA) 4 is closely associated with a number of chronic inflammatory diseases, and it was enriched as the hub protein. ROC analysis showed that SAA4 could distinguish both nAMD and PCV from the controls. Conclusion This comprehensive study provides insights into, and furthers our understanding of, the pathological mechanism of nAMD and PCV. Additionally, the SAA4 level alteration may serve as a common biomarker of nAMD and PCV.

Abstract
AIM To investigate thickness characteristics and vascular plexuses in retinas with reticular pseudodrusen (RPD) as an early detection strategy for age-related macular degeneration (AMD). METHODS This retrospective study included 24 subjects (33 eyes) with RPD and 25 heathy control subjects (34 eyes). The superficial capillary plexus (SCP) and the deep capillary plexus (DCP) of the retinal posterior poles were investigated with optical coherence tomography angiography (OCTA). Retinal thicknesses and vessel densities were analyzed statistically. RESULTS The general retinal thicknesses of RPD eyes were significantly decreased (95%CI -14.080, -0.655; P=0.032). The vessel densities of DCP in RPD eyes were significantly increased in the global (95%CI 1.067, 7.312; P=0.027), parafoveal (95%CI 0.417, 5.241; P=0.022), and perifoveal (95%CI 0.181, 6.842; P=0.039) quadrants. However, the vessel densities of the SCP were rarely increased in the eyes with RPD. CONCLUSION The thinning of retinas in the RPD group suggests a reduction in the number of cells. Additionally, the increased vessel density of the DCP in retinas with RPD indicates a greater demand for blood supply, possibly due to the hypoxia induced RPD compensation caused by RPD in the outer retina. This study highlights the pathological risks associated with RPD and emphasizes the importance of early intervention to retard the progression of AMD.

Abstract
Polypoidal choroidal vasculopathy (PCV) is a subtype of neovascular age-related macular degeneration (nAMD) that is characterized by a branching neovascular network and polypoidal lesions. It is important to differentiate PCV from typical nAMD as there are differences in treatment response between subtypes. Indocyanine green angiography (ICGA) is the gold standard for diagnosing PCV; however, ICGA is an invasive detection method and impractical for extensive use for regular long-term monitoring. In addition, access to ICGA may be limited in some settings. The purpose of this review is to summarize the utilization of multimodal imaging modalities (color fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), and fundus autofluorescence (FAF)) in differentiating PCV from typical nAMD and predicting disease activity and prognosis. In particular, OCT shows tremendous potential in diagnosing PCV. Characteristics such as subretinal pigment epithelium (RPE) ring-like lesion, en face OCT-complex RPE elevation, and sharp-peaked pigment epithelial detachment provide high sensitivity and specificity for differentiating PCV from nAMD. With the use of more practical, non-ICGA imaging modalities, the diagnosis of PCV can be more easily made and treatment tailored as necessary for optimal outcomes.

Subfoveal choroidal thickness as a potential predictor of treatment response after intravitreal ranibizumab injections for polypoidal choroidal vasculopathy. CANADIAN JOURNAL OF OPHTHALMOLOGY 2023; 58:82-89.

Abstract
OBJECTIVE To evaluate the impact of subfoveal choroidal thickness (SFCT) and other clinical biomarkers in intravitreal anti-vascular endothelial growth factor response in treatment-naive Caucasian patients diagnosed with polypoidal choroidal vasculopathy (PCV/AT1). DESIGN Cross-sectional study. PARTICIPANTS Treatment-naive patients diagnosed with PCV/AT1 recruited in a single centre from January 2013 to December 2020. METHODS Eligibility was determined in treatment-naive PCV patients who received a loading dose of 3 injections of 0.5 mg ranibizumab. A diagnosis of PCV/AT1 was made based on the diagnostic criteria in the efficacy and safety of verteporfin photodynamic therapy in combination with ranibizumab or alone versus ranibizumab monotherapy in patients with sumptomatic macular polypoidal choroidal vasculopathy study. Choroidal thickness was manually measured by enhanced depth imaging technology in Spectralis spectral domain optical coherence tomography. RESULTS Eighty-three eyes of 83 patients were included in this study, 47 patients diagnosed with PCV/AT1 with a good response to 3 intravitreal injections of ranibizumab and 36 with a poor response. The receiver operating characteristic curve of treatment effect against the SFCT revealed that the area under the curve was 0.85 (range, 0.74-0.96). Based on the Youden index, the optimal SFCT cut-off point for predicting a poor response to anti-vascular endothelial growth factor is 257 µm. In the multivariate analysis, the SFCT remained statistically significant (odds ratio 1.02 [range, 1.01-1.04]; P = 0.008). The combined effect of treatment effect against clinical biomarkers produced an area under the curve of 0.90 (range, 0.82-0.98). CONCLUSION SFCT is a risk factor for a poor response to the 3 loading injections of ranibizumab in treatment-naive PCV/AT1 Caucasian patients. A cut-off point of 257 µm could be a valuable parameter for defining the population at risk for an inadequate response to ranibizumab.

Abstract
AIMS To report the 6-year incidence of optical coherence tomography (OCT)-derived age-related changes in drusen volume and related systemic and ocular associations. METHODS Chinese adults aged 40 years and older were assessed at baseline and 6 years with colour fundus photography (CFP) and spectral domain (SD) OCT. CFPs were graded for age-related macular degeneration (AMD) features and drusen volume was generated using commercially available automated software. RESULTS A total of 4172 eyes of 2580 participants (mean age 58.12±9.03 years; 51.12% women) had baseline and 6-year follow-up CFP for grading, of these, 2130 eyes of 1305 participants had gradable SD-OCT images, available for analysis. Based on CFP grading, 136 (3.39%) participants developed incident early AMD and 10 (0.25%) late AMD. Concurrently, retinal pigment epithelial-Bruch's membrane (RPE-BrC) volumes decreased, remained stable and increased in 6.8%, 78.5% and 14.7%, respectively, over 6 years. In eyes where RPE-BrC volumes were >0 mm3 at baseline, this was associated with two-fold higher prevalence rate of any AMD at baseline (p<0.001). Multivariable analysis showed that when compared with eyes where RPE-BrC volume was unchanged, volume decrease was significantly associated with older age (OR=1.30; p<0.001), smoking (OR=2.21; p=0.001) and chronic kidney disease (OR=3.4, p=0.008), while increase was associated with older age (OR=1.36; p<0.001) and hypertension (OR=1.43; p=0.016). CONCLUSION AMD incidence detected at 6 years on CFP and correlated OCT-derived drusen volume measurement change is low. Older age and some systemic risk factors are associated with drusen volume change, and our data provide new insights into relationship between systemic risk factors and outer retinal morphology in Asian eyes.

Abstract
Background/aimsDemonstrate that subretinal drusenoid deposits (SDDs) in age-related macular degeneration (AMD) are linked to coexistent high-risk vascular diseases (HRVDs).MethodsCross-sectional study. Two hundred AMD subjects (aged 51–100 years; 121 women, 79 men) were recruited. Spectral domain optical coherence tomography, autofluorescence and near-infrared reflectance imaging, and lipid profiles were obtained. Subjects were assigned by health history questionnaires into those with or without HRVDs, defined as: cardiac valve defect (eg, aortic stenosis), myocardial defect (eg, myocardial infarction) and stroke/transient ischaemic attack. Masked readers assigned subjects into two groups: SDD (with or without drusen) and drusen (only). Univariate testing was performed by χ2test. We built multivariate regression models to test relationships of coexistent HRVD to SDD status, lipid levels and other covariates.ResultsThe prevalence of HRVD was 41.2% (40/97) and 6.8% (7/103) in the SDD and non-SDD groups, respectively (correlation of SDD with HRVD, p=9×10−9, OR 9.62, 95% CI 4.04 to 22.91). Multivariate regressions: only SDDs and high-density lipoprotein (HDL) in the first two HDL quartiles remained significant for HRVD (p=9.8×10−5, 0.021, respectively). Multivariate regression model: SDDs and an HDL in Q1 or Q2 identified the presence of HRVD with the accuracy of 78.5%, 95% CI 72.2% to 84.0%.ConclusionsHigh-risk cardiovascular and neurovascular diseases were accurately identified in an AMD cohort from SDDs and HDL levels. The SDDs may be related to inadequate ocular perfusion resulting from the systemic vasculopathies. Further research with this paradigm is warranted and might reduce mortality and morbidity from vascular disease.

Abstract
BACKGROUND The choroidal vasculature, including the choriocapillaris and vortex veins, is essential for providing nutrients to the metabolically demanding photoreceptors and retinal pigment epithelium. Choroidal vascular dysfunction leads to vision loss and is associated with age-related macular degeneration and the poorly understood pachychoroid diseases including central serous chorioretinopathy and polypoidal choroidal vasculopathy that are characterized by formation of dilated pachyvessels throughout the choroid. METHODS Using neural crest-specific Angpt1 knockout mice, we show that Angiopoietin 1, a ligand of the endothelial receptor TEK (also known as Tie2) is essential for choriocapillaris development and vortex vein patterning. RESULTS Lacking choroidal ANGPT1, neural crest-specific Angpt1 knockout eyes exhibited marked choriocapillaris attenuation and 50% reduction in number of vortex veins, with only 2 vortex veins present in the majority of eyes. Shortly after birth, dilated choroidal vessels resembling human pachyvessels were observed extending from the remaining vortex veins and displacing the choriocapillaris, leading to retinal pigment epithelium dysfunction and subretinal neovascularization similar to that seen in pachychoroid disease. CONCLUSIONS Together, these findings identify a new role for ANGPT1 in ocular vascular development and demonstrate a clear link between vortex vein dysfunction, pachyvessel formation, and disease.

European Prevalence of Polypoidal Choroidal Vasculopathy: A Systematic Review, Meta-Analysis, and Forecasting Study. J Clin Med 2022; 11:jcm11164766. [PMID: 36013005 PMCID: PMC9410106 DOI: 10.3390/jcm11164766] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 08/01/2022] [Accepted: 08/11/2022] [Indexed: 11/17/2022] Open
Abstract
The purpose of this study was to provide an estimate of the number of current and future patients with polypoidal choroidal vasculopathy (PCV) in Europe. We systematically searched 11 literature databases on 18 May 2022 for studies on the prevalence of PCV among a consecutive and representative group of patients with suspected neovascular age-related macular degeneration (AMD). Prevalence of PCV in patients with suspected neovascular AMD was summarized and included in a prevalence meta-analysis. We then used current population data and population forecasts by Eurostat and the Office for National Statistics to determine current and future number of patients with neovascular AMD in Europe. Then, we calculated the number of patients with PCV with our calculated estimate of the prevalence of PCV among Europeans suspected with neovascular AMD. A total of five eligible studies were identified which included a total of 1359 patients. All these studies used the gold standard of indocyanine green angiography as a routine part of their diagnostic approach. Among patients undergoing detailed retinal examination for suspected neovascular AMD, our meta-analysis calculated the prevalence of PCV to be 8.3% (95% confidence interval: 6.8–9.8%). Our population estimates find that a total of 217,404 patients with PCV exist in Europe in the year 2022, which constitutes 0.04% of the entire population of Europe. This number is estimated to increase to 287,517 patients in the year 2040. Our estimates are important for different healthcare stakeholders, especially when planning and allocating expensive resources.

Abstract
BACKGROUND This study aims to achieve an automatic differential diagnosis between two types of retinal pathologies with similar pathological features - Polypoidal choroidal vasculopathy (PCV) and wet age-related macular degeneration (AMD) from volumetric optical coherence tomography (OCT) images, and identify clinically-relevant pathological features, using an explainable deep-learning-based framework. METHODS This is a retrospective study with data from a cross-sectional cohort. The OCT volume of 73 eyes from 59 patients was included in this study. Disease differentiation was achieved through single-B-scan-based classification followed by a volumetric probability prediction aggregation step. We compared different labeling strategies with and without identifying pathological B-scans within each OCT volume. Clinical interpretability was achieved through normalized aggregation of B-scan-based saliency maps followed by maximum-intensity-projection onto the en face plane. We derived the PCV score from the proposed differential diagnosis framework with different labeling strategies. The en face projection of saliency map was validated with the pathologies identified in Indocyanine green angiography (ICGA). RESULTS Model trained with both labeling strategies achieved similar level differentiation power (>90%), with good correspondence between pathological features detected from the projected en face saliency map and ICGA. CONCLUSIONS This study demonstrated the potential clinical application of non-invasive differential diagnosis using AI-driven OCT-based analysis, with minimal requirement of labeling efforts, along with clinical explainability achieved through automatically detected disease-related pathologies.

Abstract
Purpose To evaluate how the HLA genotype is associated to the polypoidal choroidal vasculopathy (PCV) in a population of patients of Afro-Caribbean descent. Methods Forty-seven patients were diagnosed with PCV. The number of control patients was 457. All affected patients and control patients were of Afro-Caribbean descent and natives to Martinique. HLA typing was based on blood sample, using the polymerase chain reaction technique. Comparison of HLA alleles between the 2 groups was done using chi-2 test, odds ratio (OR) and confidence interval using Woolf’s method. The Bonferroni correction was considered significant when p-value ≤0.05. Alleles frequency was analyzed for DRB1 and DQB1 locus. Results HLA-DRB1*13 allele was significantly associated to PCV (OR = 2.02, CI = [1.3; 3.13], p = 0.003). In group DRB1, the Bonferroni correction significance threshold was <0.004. HLA-DQB1*04 allele was significantly associated to PCV (OR = 3.5, CI = [1.48; 8.3], p = 0.006). In group DQB1, the Bonferroni correction significance threshold was <0.006. Conclusion Two HLA alleles are positively associated to PCV. The possible association between PCV and certain alleles suggest HLA implication in PCV pathogeny, most likely by modeling the immune system response.

Abstract
Central serous chorioretinopathy (CSCR) can be complicated by different types of choroidal neovascularization (CNV). The purpose of this study was to investigate the incidence and quantitative optical coherence tomography angiography (OCT-A) features of CSCR-related CNVs. Methods: This was a retrospective multicenter study including 102 eyes of 102 Caucasian patients with acute or complex CSCR. All patients underwent a comprehensive ophthalmological examination. Quantitative OCT-A parameters, including vascular perfusion density (VPD), fractal dimension (FD), and lacunarity (LAC), were measured in CNV eyes. Results: Forty eyes (39.2%) had acute CSCR, whereas the remaining sixty-two (60.8%) had complex CSCR. CNV was observed in 37 (36.27%) eyes, all of which had the complex form. CNVs were classified as type 1 CNV in 11/37 (29.73%) cases and as polypoidal choroidal vasculopathy (PCV) in the remaining 26/37 (70.27%). Overall, the mean VPD, FD, and LAC of CSCR-related CNVs were 0.52 ± 0.20%, 1.44 ± 0.12, and 2.40 ± 1.1, respectively. No significant difference between type 1 CNV and PCV was found. Conclusion: Complex CSCR is often complicated by type 1 CNV and PCV with similar neovascular architecture and branching complexity, a finding supporting the idea that they might be different stages of the same neovascular process. Future OCT-A fractal analysis-based studies that also include other relevant parameters, such as demographics, presentation, morphology on multimodal imaging, and response to treatment, are necessary before drawing any definitive conclusions.

Abstract
Purpose To compare the efficacy of initial vs. delayed photodynamic therapy (PDT) in combination with intravitreal injection of conbercept (IVC) for polypoidal choroidal vasculopathy (PCV). Design Multicenter, randomized, non-inferiority clinical trial. Subjects Naïve PCV patients. Methods Patients were randomized 1:1 into two groups: initial PDT with IVC and delayed PDT with IVC. At baseline, patients in the initial combination group were treated with PDT and IVC within 1 week, while patients in the delayed combination group were treated with IVC alone. PDT and IVC was given PRN during the follow-up in each group. Main Outcome Measures Non-inferiority of delayed PDT with IVC to initial PDT with IVC for mean change in best-corrected visual acuity from baseline to month 12 (95% CI of the difference entirely above −5 letters). Results Eighty-six patients were enrolled, with 43 in each group. At month 12, the change of BCVA in initial combination group was equivalent to that in the delayed combination group, with gains of 6.42 ± 1.89 and 7.49 ± 2.14 (mean ± standard error) letters, respectively [delayed group minus initial group: 1.07 letters; 95% confidence interval (CI): −4.62 to 6.76; Pnon−inferiority = 0.0198]. The rates of complete polyp regression were 66.67 and 45.83% in the initial and delayed combination groups, respectively. The difference was not statistically significant (P = 0.386). The mean reductions of CRT were 204.77 ± 28.79 and 84.14 ± 30.62 μm in each group respectively. The difference was statistically significant (P = 0.005). In addition, the mean injection numbers were 3.47 ± 2.39 and 4.91 ± 2.65 in each group respectively. The differences were statistically significant (P = 0.010). Conclusions There was effective in both groups in patients with PCV. The initial combination group showed a more efficient decrease in CRT and polyp regression, along with fewer injections. However, the delayed combination group was non-inferior compared with the initial combination group in terms of the improvement of BCVA.

Abstract
Background Polypoidal choroidal vasculopathy (PCV) is an exudative maculopathy with features similar to wet age macular degeneration. The incidence of PCV is known to be higher in the Asian population compared to Caucasians. Imaging modality is needed to make the diagnosis of PCV. Although Indocyanine green angiography (ICGA) is still the gold standard, it is not routinely performed in vitreoretinal practice. Thus another imaging modality is currently a popular research area. Spectral domain optical coherence tomography (SD-OCT) has emerged as a new imaging modality mostly available in clinics. Some studies have reported the sensitivity and specificity of SD-OCT in diagnosing PCV with different results and thresholds. Methods Relevant studies from PubMed, Science Direct and Google Scholar databases were systematically searched. In random effect models using STATA 14 software, a meta-analysis was performed to determine the pooled diagnostic accuracy. QUADAS 2 was used to evaluate the risk of bias of each study by Revman 5.4 software. Results Seven eligible studies which met the inclusion and exclusion criteria were enrolled in this study. A total of 911 eyes were included to investigate the diagnostic accuracy of SD-OCT. As a result, the pooled sensitivity was 0.91 (95% CI 0.87–0.93), specificity 0.88 (95% 0.83–0.92), positive likelihood ratio 8, negative likelihood ratio 11, the area under the summary receiver operating characteristic curve 0.95 (95% CI 0.93–0.97), and diagnostic odds ratio 71.81 (95% CI 38.89–132.74). Conclusion SD-OCT provided a high diagnostic value for detecting PCV. Sharply peaked pigment epithelial detachment (PED), notched PED, bubble sign, multiple PED, and double-layer sign were the most common features found in PCV.

Abstract
The aim of this study was to evaluate influence of baseline imaging features on visual and anatomical outcomes in eyes with PCV treated with anti-VEGF monotherapy. In this prospective study we enrolled participants with treatment-naïve PCV who followed a treat-and-extend protocol using intravitreal aflibercept (IVA) monotherapy. Baseline clinical features evaluatedincluded best corrected visual acuity (BCVA), traditional features such as lesion size, fluid-related OCT parameters and novel parameters using automated software. This included quantitative and qualitative pigment epithelium detachment (PED) parameters [height, volume]; and choroidal parameters. [choroidal thickness (CT), choroidal volume (CV) and choroidal vascularity index (CVI). We evaluated the predictive value of each parameter on visual and anatomical outcome at month 12. We additionally evaluated initial treatment response after 3 monthly injections with respect to month 12 outcomes. Fifty-two eyes from 52 participants were included in the study. The BCVA increased from 61.1 ± 13.2 to 69.6 ± 13.2 early treatment diabetic retinopathy study (ETDRS) letters (p < 0.01) and CRT reduced from 455.7 ± 182.4 µm to 272.7 ± 86.2 (p < 0.01) from baseline to month 12. The proportion of eyes with PED decreased significant from 100% at baseline to 80% at month 12 (p < 0.01). Reduction in the mean maximum height of PED (from 381.3 ± 236.3 µm to 206.8 vs ± 146.4 µm) and PED volume (from 1322 ± 853 nl to 686 ± 593 nl) (p < 0.01) was also noted from baseline to month12. Baseline features associated with better month 12 BCVA included baseline BCVA (β = − 0.98, 95%CI − 3.38 to − 1.61, p = 0.02) and baseline CRT (β = − 0.98, 95%CI − 1.56 to − 0.40, p = 0.04) while the disease activity at month12 was significantly associated with lower baseline CRT (366.0 ± 129.5 vs 612.0 ± 188.0 , p < 0.001), lower baseline PED height (242.0 ± 150.0 vs 542.0 ± 298.0 µm, p < 0.01), lower baseline PED volume (0.6 ± 0.3 mm3 vs 2.2 ± 1.3 mm3 vs, p < 0.01), lower proportion with marked CVH (17.9% vs 46.2%, p = 0.02) and lower mean CVI (61.8 ± 1.4 vs 63.0 ± 1.4, p < 0.02). Additionally, a larger decrease in CRT (per 100 nm) and larger PED volume reduction (per 100 nl) at month 3 from baseline were associated with greater BCVA gain and inactive disease. PED-related volumetric parameters have an additional predictive value to traditional biomarkers of disease activity in eyes with PCV undergoing anti-VEGF monotherapy. With increasingly precise quantification, PEDs can be a crucial biomarker in addition to traditional parameters and may aid in retreatment decisions.

Xue Y, Qinhua C. Short-Term Efficacy in Polypoidal Choroidal Vasculopathy Patients Treated With Intravitreal Aflibercept or Conbercept. Front Med (Lausanne) 2022; 9:835255. [PMID: 35252267 PMCID: PMC8891458 DOI: 10.3389/fmed.2022.835255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Accepted: 01/10/2022] [Indexed: 12/03/2022] Open
Abstract
Purpose To compare the short-term efficacy in patients with polypoidal choroidal vasculopathy (PCV) treated using either aflibercept or conbercept. Methods This prospective study included 41 patients with treatment-naive PCV (42 eyes). All the patients were treated with either aflibercept or conbercept using an initial series of 3 monthly loading injections. Changes in the best-corrected logMAR visual acuity (BCVA) and anatomic outcomes were evaluated at 3 months. Results BCVA was improved with reduction in central choroidal thickness (CCT), central foveal thickness (CFT), and subretinal fluid (SRF) after 3 monthly loading injections in both aflibercept (IVA) and conbercept (IVC) groups. There was no significant difference in either visual or anatomic outcomes between the two groups after 3 months of treatment. However, compared with the IVC group, significantly higher BCVA improvement was observed in the patients in the IVA group with baseline BCVA better than 1. A visual outcome improved ≥3 lines in 13 patients in the IVA group (59%), and 9 patients in the IVC group (45%). A relatively high proportion of polyp regression was observed in the IVA group (63%) compared with the IVC group (55%) via OCTA. Conclusions Visual and anatomic outcomes were significantly improved in both IVA and IVC groups, but the results suggest a potentially superior short-term response in the IVA group.

Abstract
PURPOSE The aim of this study was to estimate the cost-utility and budget impact of pharmacological treatments for the eye with polypoidal choroidal vasculopathy (PCV) in Thailand. METHODS A Markov model-based cost-utility analysis (CUA) and budget impact analysis were conducted. The lifetime cost and outcomes of PCV treatments were estimated. We discounted costs and outcomes at 3% per annum. Parameters were estimated using data from published literatures, local cost and utility data, and epidemiology data among Thai patients. Univariate and probabilistic sensitivity analyses were performed to account for parameter uncertainty. RESULTS Intravitreal bevacizumab (IVB) resulted in the lowest lifetime cost, followed by IVB plus verteporfin photodynamic therapy (IVB+vPDT) and intravitreal aflibercept (IVA). The combination of IVB or intravitreal ranibizumab (IVR) and verteporfin photodynamic therapy (IVB+vPDT or IVR+vPDT) yielded the highest quality-adjusted life-years (QALY). When compared with IVB from a societal perspective, the incremental cost-effectiveness ratio for patients with PCV receiving IVB+vPDT, IVR+vPDT, IVA were 10,304; 54,135; and 82,738 the United States dollar (USD) per QALY gained, respectively. At the Thai societal willingness to pay threshold of 4884 USD, IVB had the highest probability of being cost-effective (99%) followed by IVB+vPDT (1%). IVB+vPDT could be a cost-effective strategy and required a budget of 12.61 million USD over five fiscal years when the price of verteporfin reduced by approximately 45%. CONCLUSION None of the drug treatments for PCV was cost-effective in the Thai context. The decreased price of verteporfin is required to support the inclusion of IVB+vPDT in the Thai National List of Essential Medicines for the treatment of PCV.

Clinical features and prognosis of polypoidal choroidal vasculopathy with different morphologies of branching vascular network on optical coherence tomography angiography. Sci Rep 2021; 11:17848. [PMID: 34497317 PMCID: PMC8426494 DOI: 10.1038/s41598-021-97340-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Accepted: 08/25/2021] [Indexed: 11/17/2022] Open
Abstract
This study highlights the clinical features and treatment response of polypoidal choroidal vasculopathy (PCV) among three different branching vascular network (BVN) morphologies in optical coherence tomography angiography (OCTA), and further correlates the BVN features with those under fluorescent angiography (FA) and indocyanine green angiography (ICGA). In total, we reviewed 70 eyes with PCV followed up for > 12 months. OCTA, ICGA and FA images were obtained at baseline and post-treatments. BVN was assessed using OCTA and divided into three types by a previously described BVN classification: type 1 (trunk), type 2 (glomeruli), and type 3 (stick). At baseline, type 1 BVN had the poorest vision and thinnest subfoveal choroidal thickness (SFCT), whereas type 3 had the best vision and thickest SFCT. The aforementioned trend sustained after treatments. Each BVN morphology in OCTA showed typical features in FA + ICGA and encompassed significant correlation (p = 0.004). In conclusion, OCTA is an innovative imaging tool for the detection and classification of BVN in PCV. Furthermore, OCTA has advantages of being noninvasive and free of systemic toxicities. The BVN can be divided into three types based on morphological characteristics in OCTA, which play crucial roles in clinical presentations and treatment outcomes.

Abstract
Recent improvements in ophthalmic imaging have led to the identification of a thickened choroid or pachychoroid to be associated with a number of retinal diseases. The number of conditions linked to this phenotype has continued to widen with specific endophenotypes found within the pachychoroid spectrum. The spectrum includes choroidal features such as focal or diffuse choroidal thickening and thinning of the overlying inner choroid, and choroidal hyperpermeability as demonstrated by indocyanine green angiography. In addition, these diseases are associated with overlying retinal pigmentary changes and retinal pigment epithelial dysfunction and may also be associated with choroidal neovascularization. This article provides a comprehensive review of the literature looking at diseases currently described within the pachychoroid spectrum including central serous chorioretinopathy, pachychoroid pigment epitheliopathy, pachychoroid neovasculopathy, polypoidal choroidal vasculopathy/aneurysmal type 1 neovascularization, peripapillary pachychoroid disease and focal choroidal excavation. We particularly focus on clinical imaging, genetics and pathological findings in these conditions with the aim of updating evidence suggesting a common aetiology between diseases within the pachychoroid spectrum.

Abstract
Aetiological processes of polypoidal choroidal vasculopathy (PCV) remains poorly understood, but several studies indicate that immunity may play a role and report elevated levels of systemic C-reactive protein (CRP). In this systematic review and meta-analysis, we summarize available evidence in the field. We searched the databases PubMed/MEDLINE, EMBASE, Web of Science and the Cochrane Central on 19 March 2020. Two independent authors reviewed the studies and extracted data. Two independent authors reviewed the studies, extracted data and evaluated risk of bias within individual studies. Studies were reviewed in the text qualitatively and measures of association were included for quantitative analyses. Results from univariate analyses and multivariate-adjusted analyses were included for separate meta-analyses to evaluate whether the association was only due to factors associated with PCV. Four studies (246 patients with PCV and 2861 control individuals) were identified and included for a qualitative and quantitative analysis. Increased CRP was associated with PCV when pooling both univariate measures (OR 3.54, 95% CI: 2.13-5.89, p < 0.0001) and multivariate-adjusted measures (OR 3.05, 95% CI: 1.56-5.98, p = 0.0011). Sensitivity analyses confirmed robustness of the results. Increased CRP is associated to PCV, even after adjusting for demographics, lifestyle factors and co-morbidities. Clinical value of CRP in relation to PCV remains unclear, but the association gives much needed insight into the aetiology of a poorly understood disease.

Drusen and pigment abnormality predict the development of neovascular age-related macular degeneration in Japanese patients. PLoS One 2021; 16:e0255213.

Abstract
Drusen are known to be the important hallmark to predict the development of age-related macular degeneration (AMD). The prevalence of drusen is lower in Asians compared with Caucasians so that the role of signs constituting early AMD is not well established in Asian populations as in Western countries. In this study, we retrospectively investigated clinical characteristics and 5-year incidence of neovascular AMD (nAMD) in the fellow eye of unilateral nAMD patients. Of 296 consecutive unilateral nAMD patients who had been followed up more than 5 years, 170 typical AMD, 119 polypoidal choroidal vasculopathy, and 7 retinal angiomatous proliferation were included. To examine factors associated with nAMD occurrence in the fellow eye, drusen and pigmentary abnormality in the fellow eye were classified into 4 categories; Category 1: no or small drusen < 63 μm (37.2%), Category 2: 63–125 μm medium drusen or pigmentary abnormality (22.2%), Category 3: large drusen > 125 μm (25.0%), Category P: pachydrusen (15.5%). The mean sub-foveal choroidal thickness (SFCT) was Category 1: 276 μm, Category 2: 308 μm, Category 3: 246 μm, and Category P: 302 μm, respectively. Of note, SFCT in Category 2 and Category P was significantly larger than those of Category 3. Finally, the 5-year incidence of nAMD in the fellow eye was 32/296 (10.8%); Category 1: 0/110 (0%), Category 2: 12/66 (18.2%), Category 3: 20/74 (27.0%), and Category P: 0/46 (0%). Thus, signs of intermediate AMD (large drusen) as well as those of early AMD, especially the pigmentary abnormality, may contribute to development of bilateral nAMD in Japanese patients.

Abstract
PURPOSE To compare the efficacy and safety of intravitreal aflibercept (IVA) monotherapy versus aflibercept combined with reduced-fluence photodynamic therapy (RF-PDT) (IVA+RF-PDT) for the treatment of polypoidal choroidal vasculopathy (PCV). METHODS AND ANALYSIS Multicentred, double-masked, randomised controlled trial to compare the two treatment modalities. The primary outcome of the study is to compare the 52-week visual outcome of IVA versus IVA+RF PDT. One hundred and sixty treatment-naïve patients with macular PCV confirmed on indocyanine green angiography will be recruited from three centres in Singapore. Eligible patients will be randomised (1:1 ratio) into one of the following groups: IVA monotherapy group-aflibercept monotherapy with sham photodynamic therapy (n=80); combination group-aflibercept with RF-PDT (n=80). Following baseline visit, all patients will be monitored at 4 weekly intervals during which disease activity will be assessed based on best-corrected visual acuity (BCVA), ophthalmic examination findings, optical coherence tomography (OCT) and angiography where indicated. Eyes that meet protocol-specified retreatment criteria will receive IVA and sham/RF-PDT according to their randomisation group. Primary endpoint will be assessed as change in BCVA at week 52 from baseline. Secondary endpoints will include anatomical changes based on OCT and dye angiography as well as safety assessment. Additionally, we will be collecting optical coherence tomography angiography data prospectively for exploratory analysis. ETHICS AND DISSEMINATION This study will be conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and that are consistent with the ICH E6 guidelines of Good Clinical Practice and the applicable regulatory requirements. Approval from the SingHealth Centralised Institutional Review Board has been sought prior to commencement of the study. TRIAL REGISTRATION NUMBER NCT03941587.

Abstract
Anti-vascular endothelial growth factor (anti-VEGF) therapy currently plays a central role in the treatment of numerous retinal diseases, most notably exudative age-related macular degeneration (eAMD), diabetic retinopathy and retinal vein occlusions. While offering significant functional and anatomic benefits in most patients, there exists a subset of 15–40% of eyes that fail to respond or only partially respond. For these cases, various treatment options have been explored with a range of outcomes. These options include steroid injections, laser treatment (both thermal therapy for retinal vascular diseases and photodynamic therapy for eAMD), abbreviated anti-VEGF treatment intervals, switching anti-VEGF agents and topical medications. In this article, we review the effectiveness of these treatment options along with a discussion of the current research into future directions for anti-VEGF-resistant eyes.

Abstract
PURPOSE The aim of the study was to characterize the morphological features of polypoidal choroidal vasculopathy (PCV) in a large Caucasian population. METHODS We conducteda multicenter, cross-sectional study of treatment-naïve patients with PCV. Baseline fundus photography, spectral-domain optical coherence tomography (SD-OCT), fluorescein angiography (FA), and indocyanine green angiography (ICGA) were assessed by trained medical graders. Typical PCV features were explored, and retinal thickness (RT) and choroidal thickness (CT) measurements were performed. RESULTS Seventy-nine eyes of 73 patients (mean age, 72.6 ± 11.9 years) were included. ICGA identified macular polyps in 89.9% of cases. SD-OCT revealed mostly subretinal fluid (93.6%) and a retinal pigment epithelium (RPE) detachment in 91.4%, with sharp protrusion in 67.0% of cases. Polyp-like structures were seen in 74.3% of cases, mostly adherent to an elevated RPE (69.6%). Type 1 neovascularization (NV) was identified in 74.7% of patients, while 16.5% had a mixed NV. The mean macular CT was 220.9 ± 83.2 μm (range, 67.9-403.6). Diffuse and focal pachychoroid were observed in 26.6 and 30.4% of patients, respectively. Soft drusen were reported in 62.0% of cases, but retinal hemorrhage occurred in only 19.0% of cases. CONCLUSION The morphological features of PCV in Caucasians are similar to those reported in Asians. Pachychoroid signs were found in nearly half of our cohort. However, the mean age at presentation, high prevalence of soft drusen, and low prevalence of large subretinal hemorrhages make PCV closer to age-related macular degeneration in this ethnic group.

Chhablani J, Singh S, Goud N, Goud A, Sahoo N, Narayanan R. One year outcomes of eyes with polypoidal choroidal vasculopathy with ≥20/40 visual acuity treated with anti-vascular endothelial growth factor agents. Saudi J Ophthalmol 2021; 35:84-87. [PMID: 35391819 PMCID: PMC8982935 DOI: 10.4103/1319-4534.337862] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2019] [Revised: 07/14/2020] [Accepted: 12/01/2020] [Indexed: 11/04/2022] Open
Abstract
PURPOSE: To report the 12 months outcomes of treatment naïve polypoidal choroidal vasculopathy (PCV) in patients with ≥20/40 Snellen's best-corrected visual acuity (BCVA). METHODS: This was a retrospective study including eyes treated with monotherapy of anti-vascular endothelial growth factors (VEGF) agents (bevacizumab, ranibizumab, aflibercept, and ziv-aflibercept) on a pro-re-nata (PRN) protocol. Photodynamic therapy using verteporfin (vPDT) was used as rescue therapy. The primary study objective was change in BCVA at 12 months. Secondary objectives included change in optical coherence tomography parameters: central macular thickness (CMT) and pigment epithelial detachment (PED) height, the mean number of injections, and treatment-free interval at 12 months. RESULTS: A total of 18 eyes of 18 patients (7 males, 11 females) were included. The mean age was 58.0 ± 12.0 years. BCVA at baseline and 12 months were 0.16 ± 0.08 (Snellen equivalent 20/30) and 0.15 ± 0.15 logarithm of the minimum angle of resolution (20/30), respectively. Twelve (66.6%) eyes either improved or maintained BCVA. Mean (±standard deviation [SD]) CMT at baseline and 12 months were 188.2 ± 61.1 μ and 161.7 ± 47.4 μ (P = 0.15), respectively. PED height improved to 236.4 ± 208.7 μ at 12 months (P = 0.05). The mean (±SD) number of injections was 3.28 ± 1.96 with a treatment-free period of 6.83 ± 3.63 months. Three eyes required vPDT (4 treatment sessions; mean: 1.33) as a rescue therapy through 12 months. CONCLUSION: PRN anti-VEGF monotherapy in real-life situations for the treatment of naïve PCV eyes with good visual acuity (≥20/40) achieves maintenance or improvement of visual acuity through 12 months follow-up.

The polyp regression rate and treatment prognosis of different interventions for polypoidal choroidal vasculopathy: a systematic review and meta-analysis. Graefes Arch Clin Exp Ophthalmol 2020; 259:855-872. [PMID: 33119802 DOI: 10.1007/s00417-020-04977-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Revised: 09/18/2020] [Accepted: 10/09/2020] [Indexed: 11/25/2022] Open
Abstract
PURPOSE To estimate the polyp regression rate and treatment prognosis of different interventions for polypoidal choroidal vasculopathy (PCV) and clarify its baseline characteristics. METHODS The PubMed, EMBASE, and Ovid were searched up to January 2020 to identify related studies. R software version 3.6.3 was used to perform the statistical analyses. Results in proportion with 95% confidence interval (CI) were calculated by means of the Freeman-Tukey variant of arcsine square transformation. Chi-squared test and I2 statistics were used to evaluate the statistical heterogeneity. Sensitivity analysis and subgroup analyses were performed to identify the source of heterogeneity. RESULTS This meta-analysis included 104 studies with 5816 patients. The pooling results indicated the general rate of complete polyp regression at post-treatment 12 months was 64% (95% CI [57~71%]), 89% (95% CI [81~95%]) for photodynamic therapy (PDT) monotherapy, 78% (95% CI [68~86%]) for PDT plus anti-vascular endothelial growth factor (anti-VEGF), and 42% (95% CI [35~49%]) for anti-VEGF monotherapy; PDT plus anti-VEGF showed the best efficacy in visual improvement and achieved the highest rate of dry macula (91%, 95% CI [78~99%]), while anti-VEGF monotherapy achieved the lowest polyp recurrence rate (14%, 95% CI [8~20%]); PDT monotherapy showed the best efficacy in pigment epithelial detachment regression (66%, 95% CI [58~83%]). Additionally, the baseline characteristics of PCV were also well described. CONCLUSION PDT plus anti-VEGF is still valuable for the management of PCV; it could achieve not only satisfactory anatomical outcomes like dry macula rate and polyp regression rate but also ideal visual prognosis like BCVA improvement.

Abstract
PURPOSE To compare phenotypic and genetic variations in polypoidal choroidal vasculopathy (PCV) between Caucasian and Asian patients. METHODS We analysed phenotypic and genotypic data from two sites, Association for Innovation and Biomedical Research on Light and Image, Portugal and Singapore National Eye Centre, Singapore. Baseline fundus photography, spectral domain-optical coherence tomography, indocyanine green and fluorescein angiography scans were analysed by respective reading centres using a standardised grading protocol. Single nucleotide polymorphisms across 8 PCV loci were compared between cases and controls selected from each population. RESULTS One hundred and forty treatment-naïve PCV participants (35 Portuguese and 105 Singaporean) were included. The Portuguese cohort were older (72.33±8.44 vs 68.71±9.40 years, p=0.043) and were comprised of a lower proportion of males (43% vs 71%, p=0.005) compared with the Singaporean cohort. Differences in imaging features include higher prevalence of soft drusen (66% vs 30%, p=0.004), lower prevalence of subretinal haemorrhage (14% vs 67%, p<0.001), smaller polypoidal lesion (PL) area (0.09±0.09 vs 0.76±0.93 mm2, p<0.001), lower ratio of PL to branching vascular network area (3% vs 38%, p<0.001) and lower central retinal thickness (346.48±93.74 vs 493.16±212.92 µm, p<0.001) in the Portuguese cohort. CETP rs3764261 (OR 2.467; 95% CI 1.282 to 4.745, p=0.006) in the Portuguese population was significantly associated with PCV and CFH rs800292 (OR 1.719; 95% CI 1.139 to 2.596, p=0.010) in the Singaporean population, respectively. CONCLUSION Among Asian and Caucasian patients with PCV, there are significant differences in the expression of phenotype. We also identified different polymorphisms associated with PCV in the two populations.

Abstract
Ageing of the retina is associated with the gradual accumulation of basal deposits and the formation of drusen. However, in some individuals this process is exacerbated and causes development of age-related macular degeneration. Late features of age-related macular degeneration include geographic atrophy of the neuroretina or choroidal neovascularization. Such changes lead to blurred vision, metamorphopsia, and scotoma, and is the leading cause of vision loss in developed countries. Chronic low-grade inflammation has been investigated because of its relationship to ageing and its role in the gap between chronological and biological ageing. Here, we systematically reviewed studies investigating systemic C-reactive protein in patients with age-related macular degeneration. We identified 53 studies with 60,598 participants (10,392 patients and 38,901 controls). Our meta-analyses revealed that early age-related macular degeneration was not associated to systemic C-reactive protein (Cohen's d = 0.03 [-0.04 to 0.10]; OR = 1.06 [0.93-1.20]; P = 0.39) whereas late age-related macular degeneration (Cohen's d = 0.38 [0.24 to 0.51]; OR = 1.99 [1.55-2.52]; P < 0.0001), and neovascular age-related macular degeneration (Cohen's d = 0.40 [0.24 to 0.56]; OR = 2.07 [1.55-2.76]; P < 0.0001) was associated with a small-to-moderate increase in systemic C-reactive protein. Our review provides an overview of this extensively studied field, provide summary estimates that provide insight into when and to what extent systemic C-reactive protein is associated with age-related macular degeneration, and help in distinguishing the potentially reversible disease processes from that of irreversible retinal ageing.

J Clin Med 2020; 9:jcm9082637. [PMID: 32823822 PMCID: PMC7463565 DOI: 10.3390/jcm9082637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 08/03/2020] [Accepted: 08/11/2020] [Indexed: 11/16/2022] Open
Abstract
Background: The aim of this study was to evaluate outcomes in patients with submacular hemorrhage secondary to polypoidal choroidal vasculopathy (PCV) after switching treatment from a fixed-dose to an as-needed regimen. Methods: This retrospective study included 19 patients with submacular hemorrhage secondary to PCV who were treated with fixed-dose intravitreal aflibercept during the first 56 weeks. After 56 weeks, the treatment regimen was switched to an as-needed regimen. The incidence and timing of lesion reactivation during the as-needed phase were evaluated. The best-corrected visual acuity (BCVA) at baseline (beginning of the regimen) and the final follow-up were compared. Multivariate analysis was performed to determine the factors associated with lesion reactivation. Results: During the mean follow-up period of 27 ± 7.3 months, lesion reactivation was noted in 10 patients (52.6%; mean time period: 12.2 ± 9.1 months) in the as-needed phase. Reactivations were treated with anti-vascular endothelial growth factor (VEGF) injections (mean, 4.1 ± 2.6). The mean logarithm of the minimum angle of resolution (logMAR) BCVA was 0.26 ± 0.34 at baseline and 0.31 ± 0.38 at final follow-up (p = 0.212). Deterioration of ≥0.2 logMAR BCVA was noted in two patients (10.5%). In multivariate analysis, large lesion size was closely associated with a high risk of lesion reactivation (p = 0.009). Conclusion: Visual acuity was relatively stable after switching from a fixed-dose to an as-needed regimen, with no definite visual deterioration in the majority of patients. We conclude that patients with large lesions should be carefully monitored when switching to an as-needed regimen.

Abstract
PURPOSE Chemokines are a group of cytokines that guide immune cell migration. We studied plasma levels of inflammatory chemokines in patients with polypoidal choroidal vasculopathy (PCV) and compared with healthy age-matched control individuals. METHODS This was a clinic-based prospective case-control study of participants (n = 60) with either PCV (n = 26) or age-matched healthy controls (n = 34). We sampled fresh venous blood and isolated plasma for analysis. We used U-PLEX Human Assays to quantify concentrations of the inflammatory chemokines MCP-1/CCL2, RANTES/CCL5, eotaxin/CCL11, IP-10/CXCL10 and fractalkine/CX3CL1. RESULTS Plasma levels of fractalkine was significantly higher in patients with PCV when compared to healthy controls (mean ± SD: 7291 ± 2461 pg/ml versus 5879 ± 2001 pg/ml; p = 0.021). Plasma levels of MCP-1 (p = 0.846), RANTES (p = 0.288), eotaxin (p = 0.496) and IP-10 (p = 0.352) did not differ significantly between the groups. To evaluate possible biomarker quality of fractalkine, we used a ROC analysis and found a positive but weak discriminatory ability (AUC = 0.68). CONCLUSION Patients with PCV have a higher plasma level of fractalkine. Although the differences do not possess strong biomarker qualities, they inform on disease processes of a poorly understood disease and suggest that the fractalkine-CX3CR1 axis may be involved. As this study did not investigate local chemokine concentrations, we are unable to confirm or disprove any local chorioretinal interaction, and our findings should be interpreted with such caution.

Vision (Basel) 2020; 4:vision4020027. [PMID: 32429088 PMCID: PMC7356191 DOI: 10.3390/vision4020027] [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: 03/20/2020] [Revised: 05/08/2020] [Accepted: 05/13/2020] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of metalloproteinases 1 (TIMP-1) are regulating enzymes of the extracellular matrix. A systemic imbalance of MMP-9 and TIMP-1, thought to reflect an imbalance of the extracellular matrix homeostasis, is previously associated with polypoidal choroidal vasculopathy (PCV) in Asian patients. Previous studies suggest inter-ethnical differences in the genetic background and etiology of PCV. To further explore this issue, we studied the plasma levels of MMP-9 and TIMP-1 in Caucasian patients with PCV and compared to healthy age-matched controls. METHODS For this prospective case-control study, 60 participants were recruited who were either patients with PCV (n = 26) or healthy controls (n = 34). All participants underwent detailed clinical examination. We sampled fresh venous blood, isolated plasma, and quantified plasma concentrations of the extracellular matrix regulators MMP-9 and TIMP-1 using electrochemiluminescence immunoassays. RESULTS Plasma levels of MMP-9 (p = 0.4), TIMP-1 (p = 0.9), and MMP-9/TIMP-1 ratio (p = 0.4) did not differ significantly between patients with PCV and healthy controls. No differences appeared after adjusting for influencing co-variates in multivariate analyses. CONCLUSION We demonstrate that Caucasian patients with PCV do not have altered levels of plasma MMP-9 or plasma TIMP-1. These findings suggest no strong evidence of a systemic imbalance of the extracellular matrix homeostasis in Caucasian patients with PCV. Our findings are in line with studies of other aspects of PCV that are also subject to significant inter-ethnical differences.

Abstract
Aim To assess prevalence, clinical presentation and multimodal imaging characteristics of polypoidal choroidal vasculopathy (PCV) in a hospital-based setting in South India. Methods Electronic medical records (EMR) of new patients presenting with suspected clinical signs of wet age-related macular degeneration (AMD) in a tertiary hospital from January to December 2016 were retrospectively analyzed using keywords and filtered for patient who underwent multimodal imaging. Clinical presentations were categorized into predominantly hemorrhagic, exudative or mixed pattern. The imaging features were compared in these clinical groups. The multimodal images were graded by two masked graders and discrepancies between them were settled by a senior arbitrator. Results Of the 147 clinically suspicious cases of PCV out of 785 patients with clinical presentation of AMD as recorded in the EMR, 73 (49.7%) patients had a multimodal imaging diagnosis of PCV. There was no difference in the demography, distribution of polyps, ICGA and OCT characteristics in eyes presenting with hemorrhagic, exudative or mixed clinical features. Conclusion Approximately half of South Asian patients presenting with clinical features of neovascular AMD harbor PCV irrespective of their clinical presentation and so we recommend that multimodal imaging is done in all cases of suspicious neovascular AMD in Indian population.

Abstract
PURPOSE To assess the treatment effect of intravitreal aflibercept and ranibizumab in Asian patients with neovascular age-related macular degeneration. METHODS We evaluated data from VIEW 1 and VIEW 2, comparing functional and morphologic outcomes at Week 96 between intravitreal aflibercept 2 mg monthly (2q4) or 2 mg bimonthly after 3 initial monthly doses (2q8) versus ranibizumab 0.5 mg monthly among Asian patients (n = 269) and between Asian and white patients (n = 2044). RESULTS In Asian patients, there were no significant differences between intravitreal aflibercept 2q4 and 2q8 compared with ranibizumab in mean gain in best-corrected visual acuity (10.23 and 8.35 vs. 8.51 letters). Reduction in central retinal thickness was greater for intravitreal aflibercept 2q4 (150.43 μm, P = 0.0075) and 2q8 (148.15 μm, P = 0.0126) than ranibizumab (119.46 μm). The proportion of dry retinas was greater for intravitreal aflibercept 2q4 (65.7%, P < 0.01) than ranibizumab (41.7%). There were no differences in outcomes between Asian and white patients. Serious treatment-emergent ocular adverse events occurred in <8% of treated eyes, evenly distributed across subgroups. CONCLUSION In Asian patients with neovascular age-related macular degeneration, functional and morphologic outcomes were largely similar between intravitreal aflibercept and ranibizumab groups, and to results seen in white patients.

Abstract
PURPOSE To investigate the long-term outcome of autologous retinal pigment epithelium -choroid transplantation with a peripheral retinotomy for exudative age-related macular degeneration. METHODS In a retrospective study, we selected all patients who underwent a retinal pigment epithelium-choroid transplantation from 2007 through 2013. Exclusion criteria were age <60 years, <12 months of follow-up, and retinal pigment epithelium-choroid graft for other diseases than age-related macular degeneration. The main outcome measure was best-corrected visual acuity converted into logarithm of the minimum angle of resolution. RESULTS In this study, 81 patients were included with a mean follow-up of 38 months (SD = 19). Median best-corrected visual acuity improved from 1.30 logarithm of the minimum angle of resolution (20/400 Snellen) to 0.90 logarithm of the minimum angle of resolution (20/160 Snellen) 1 year after surgery (P < 0.001). A ≥3-line gain was achieved in 43 patients (53%) 1 year postoperatively and 37 patients (46%) preserved their visual gain until last visit. Of 4 patients with an 8-year follow-up, 3 patients had a ≥6-line gain at last visit. Severe complications were submacular hemorrhage (n = 8, 10%), macular hole (n = 6, 7%), and proliferative vitreoretinopathy (n = 3, 4%). CONCLUSION Best-corrected visual acuity improved significantly after retinal pigment epithelium-choroid transplantation in patients with age-related macular degeneration and preservation of visual gain was possible in the long term.

Abstract
Purpose To investigate possible roles of T helper (Th) cells, regulatory T cells (Tregs), and the recently mapped Th-like Tregs in patients with polypoidal choroidal vasculopathy (PCV). Methods In this prospective case-control study, we obtained fresh venous blood from patients with PCV (n = 24), age-matched healthy controls (n = 32), and patients with neovascular AMD (n = 45). All participants underwent a comprehensive ocular examination including fluorescein and indocyanine green angiography for where retinal disease was suspected. Using flow cytometry, we identified Th subsets, Tregs, and Th-like Tregs. Plasma samples were stored at -80°C to investigate plasma cytokines of interest. Results Compared to healthy controls, patients with PCV had lower percentages of Tregs (8.7% ± 2.8% vs. 7.3% ± 1.7%, P = 0.027), which were significantly more Th2-like polarized (42.6% ± 13.3% vs. 50.5% ± 13.0%, P = 0.029). These changes differed from that observed in neovascular AMD, which compared to healthy controls had fewer Th1/Th17 cells (3.6% ± 2.7% vs. 2.4% ± 2.5%, P = 0.049), comparable Treg levels, and no distinct polarization of Th-like Tregs. Because of these findings, we measured plasma IL-4 and IL-33 levels. Plasma IL-33 in patients with PCV (median 0.30 pg/mL) was twice as high compared to healthy controls (median 0.16 pg/mL; P = 0.037). Conclusions PCV associate with diminished Tregs that are polarized more into a Th2-like phenotype. This is correlated to IL-33 levels, which we also find increased in patients with PCV. Our findings suggest a possible role for Th2-like Tregs and IL-33 in PCV.

Abstract
Age-related macular degeneration (AMD) is aetiologically linked to immunological ageing and dysfunction. One aspect of this is the altered neutrophil-to-lymphocyte ratio (NLR), which in other domains have been associated with inflammation and angiogenesis, and therefore investigated in patients with AMD in several papers. In this systematic review and meta-analysis, we summarize findings in patients with AMD in relation to NLR, both qualitatively and quantitatively. We searched PubMed/MEDLINE, EMBASE, Web of Science, and the Cochrane Central and identified six studies from where we extracted data on 1178 individuals (777 patients with AMD and 401 healthy controls). Patients with AMD had a higher NLR (weighted mean difference: 0.37, CI 95% 0.08 to 0.66, p = 0.013) when compared to healthy controls. In subgroup analyses, we did not find a significant difference between patients with dry AMD and healthy controls (weighted mean difference: 0.34, CI 95% -0.03 to 0.69, p = 0.068), but did find a strong significant difference between patients with neovascular AMD and healthy controls (weighted mean difference: 0.54, CI 95% 0.23 to 0.86, p = 0.00068). Hence, we find that the association between AMD and elevated NLR may have stronger relevance to the neovascular subtype of AMD. However, the clinical value of measuring the NLR remains unclear.

Abstract
PURPOSE Polypoidal choroidal vasculopathy (PCV) is a disease with significant inter-ethnical differences. In this study, we systematically review the literature on the prevalence of PCV in whites referred with a diagnosis of exudative age-related macular degeneration (AMD). METHODS We searched PubMed, Embase, the Cochrane Library, and the Web of Science on 24 March, 2017 for studies evaluating the prevalence of PCV in white patients with exudative AMD. Data extraction and risk of bias assessments were performed in duplicate. Studies were included for a qualitative review and a meta-analysis, including subgroup analysis for differences in age and sex. RESULTS We included data from 11 studies (>2,200 participants). For diagnosis, indocyanine green angiography was used together with a set of supporting criteria on fundus examination and optical coherence tomography. Extramacular location was more prevalent in eyes with PCV. Drusen was present in the fellow eye in 17% to 27%. Pooled prevalence of PCV in white patients with exudative AMD was 8.7% (confidence interval 95%: 7.2%-10.3%). Patients with PCV were 3.7 years (confidence interval 95%: 2.1 years-5.3 years) younger than those with other exudative AMD. Sex did not differ significantly. CONCLUSION Polypoidal choroidal vasculopathy is not a rare subtype of exudative AMD in whites-it is present in approximately one in 11 patients.

Abstract
Purpose The purpose of this study was to investigate the cytokine profiles in plasma and aqueous humor of patients with choroidal neovascularization (CNV) due to exudative AMD and polypoidal choroidal vasculopathy (PCV). Methods In this cross-sectional study, 16 patients clinically diagnosed with AMD, 18 patients with PCV, and 50 age- and sex-matched cataract patients without AMD/PCV (controls) were enrolled. Study subjects were treatment naïve, and 200 μL undiluted aqueous humor and 5 mL peripheral venous blood were collected from the study subjects. Clinical samples were analyzed for 41 different cytokines by Luminex bead-based multiplex assay. Cytokines concentrations with detection rates of 50% or more were included for the analysis, and the differences in plasma and aqueous humor cytokines levels between each group were analyzed. Results The age of the patients with AMD and PCV was 70.62 ± 10.15 (mean ± SD) and 71.48 ± 9.08 years, respectively, and that in the control group was 62.8 ± 10.67 years. Aqueous humor cytokines growth-regulated oncogene (GRO), macrophage-derived chemokine (MDC), and macrophage inflammatory protein (MIP)-1α were significantly higher in AMD patients than controls (all P < 0.04), and GRO, MDC, MIP-1α, IL-8, IFN-γ-inducible protein 10, and monocyte chemotactic protein levels were significantly higher in PCV patients than controls (all P < 0.03). Soluble CD40 ligand and platelet-derived growth factor-AA levels were higher in plasma of healthy controls compared with AMD subjects. No significant differences in cytokine levels were observed between AMD and PCV patients for both plasma and aqueous humor. Conclusions In AMD and PCV patients, our data suggest that the pathologic changes are primarily driven by dysregulation of local immune factors in the eye, whereas the plasma cytokine levels are not elevated.

Abstract
PURPOSE To investigate the different imaging characteristics between unilateral and bilateral polypoidal choroidal vasculopathy (PCV) cases, based on confocal scanning laser ophthalmoscope assessment. METHODS For this retrospective case series study, diagnostic indocyanine green angiography (ICGA) and spectral domain optical coherence tomography (SD-OCT) were performed to assess the eligible PCV eyes. RESULTS Among the 53 patients at baseline, 14 showed bilateral PCV lesions, including two cases of branching vessel network (BVN) without leakage. Concerning the subfoveal choroidal thickness (SFCT), unilateral PCV eyes (326 [155-547] μm) were statistically comparable to their fellow eyes (330 [163-477] μm) (p = 0.257). However, the SFCT (228[141-273] μm) from the bilateral PCV group was significantly lower compared with both the PCV (p = 0.002) and fellow eyes (p < 0.001) from the unilateral group. Moreover, ICGA related hyperfluorescent spots were shown to have a significant positive correlation with SFCT in the unilateral PCV eyes and their fellow eyes, other than bilateral PCV cases. In addition, the drusens tended to prevail in the fellow eyes of the unilateral PCV group (46.2%), compared with bilateral cases. CONCLUSIONS Our results indicate that SFCT, ICGA related hyperfluorescent spots, and drusen were the three main imaging characteristic differences between unilateral and bilateral PCV cases.

Abstract
Polypoidal choroidal vasculopathy (PCV) is a subtype of neovascular age-related macular degeneration (nAMD), commonly seen in the Asian population. It is dissimilar in epidemiology, genetic heterogeneity, pathogenesis, natural history, and response to treatment in comparison to nAMD. Confocal scanning laser ophthalmoscopy-based simultaneous fluorescein angiography and indocyanine green angiography, spectral-domain optical coherence tomography (OCT) with enhanced depth imaging, swept-source OCT, and OCT angiography have improved the ability to detect PCV, understand its pathology, and monitor treatment response. A plethora of literature has discussed the efficacy of photodynamic therapy, anti-vascular endothelial growth factor (VEGF) monotherapy, and combination of both, but only a few studies with higher level of evidence and limited follow-up duration are available. This review discusses the understanding of PCV with respect to epidemiology, pathogenesis, clinical features, natural history, imaging techniques, and various treatment options. Recent clinical trials (EVEREST-II and PLANET study) have emphasized that either anti-VEGF monotherapy or combination treatment is equally capable to strike a balance between polyp regression and stabilization of visual acuity. The recurrent nature of the disease, the development of macular atrophy, and the long-term poor visual prognosis despite treatment are concerns that open avenues for further research.

Abstract
AIM To assess the effectiveness and safety of ranibizumab 0.5 mg in Taiwanese patients with polypoidal choroidal vasculopathy (PCV) by performing a retrospective exploratory subgroup analysis of the REAL study. METHODS REAL was a 12-month, observational, prospective, non-interventional phase IV post-marketing surveillance study conducted at 9 centers in Taiwan. The study collected data as part of the routine patient visits from the medical records of patients with neovascular age-related macular degeneration treated with ranibizumab 0.5 mg according to local standard medical practice and local label and/or reimbursement guidelines. The presence of PCV at baseline was determined using indocyanine green angiography. RESULTS At baseline, PCV was diagnosed in 64 of the 303 enrolled patients (21.1%). Of these, 41 patients (64.1%) had received prior treatment; 15 (23.4%) patients had received ranibizumab. The intent-to-treat population included 58 patients; 47 (80%) who received ranibizumab and 11 (20%) who received ranibizumab plus photodynamic therapy (PDT; 9 patients received once, 2 patients received twice). Bevacizumab was used as a concomitant medication in a similar percentage of patients who received ranibizumab (43%, n=20) or ranibizumab plus PDT (45%, n=5). In patients who received ranibizumab, visual acuity (VA) at baseline was 50.1±12.9 Early Treatment Diabetic Retinopathy Study letters, and the gain at month 12 was 1.1±17.8 letters. In patients who received ranibizumab plus PDT, VA at baseline was 51.4±15.9 letters, and there was a marked gain in VA at month 12 (14.0±9.2 letters, P=0.0009). In the intent-to-treat population, the reduction in central retinal subfield thickness from baseline at month 12 was 69.6±122.6 µm (baseline: 310.8±109.8 µm, P=0.0004). The safety results were consistent with the well-characterized safety profile of ranibizumab. CONCLUSION In real-world settings, ranibizumab 0.5 mg treatment for 12mo results in maintenance of VA and reduction in central retinal subfield thickness in Taiwanese patients with PCV. Improvements in VA are observed in patients who received ranibizumab plus PDT. There are no new safety findings.

Abstract
Polypoidal choroidal vasculopathy (PCV) is a subtype of neovascular age-related macular degeneration (AMD; nAMD) which occurs more commonly in Asian populations as compared to Caucasians. PCV and nAMD share pathological mechanisms, including pathological expression of vascular endothelial growth factor (VEGF). The advent of anti-vascular endothelial growth factor (VEGF) revolutionized the treatment of nAMD. Despite being a subtype of nAMD, PCV responds less well to VEGF inhibitors; thus, photodynamic therapy (PDT) in combination with anti-VEGF treatment may be considered. This review aims to summarize the current evidence for the treatment of PCV, especially whether VEGF inhibitors should be used alone or in combination with PDT.
