Abstract
Neovascularization of the macula, a common complication of many chorioretinal diseases such as neovascular age-related macular degeneration, polypoidal choroidal vasculopathy, and pathologic myopia results from increased synthesis of vascular endothelial growth factor (VEGF) by the retinal pigment epithelium and/or Müller cells because of localized ischemia and inflammation. The Consensus on Neovascular AMD Nomenclature (CONAN) study group acknowledged that these vessels may originate from either the choriocapillaris or the retinal microvasculature, prompting them to propose the term 'macular neovascularization' (MNV) to include intraretinal, subretinal, and sub-pigment epithelial neovascularization localized to the macula. MNV frequently appears as a grey-green macular lesion with overlying intraretinal thickening and/or subretinal exudation, causing metamorphopsia, reduced central vision, relative central scotoma, decreased reading speed, and problems with color recognition. Multimodal imaging with optical coherence tomography (OCT), OCT angiography, dye-based angiographies, fundus autofluorescence, and multiwavelength photography help establish the diagnosis and aid in selecting an appropriate treatment. The standard of care for MNV is usually intravitreal anti-VEGF injections, though thermal laser photocoagulation, verteporfin photodynamic therapy, and vitreoretinal surgery are occasionally used. This current review discusses the etiology and clinical features of MNV, the role of multimodal imaging in establishing the diagnosis, and the available therapeutic options.

Graefes Arch Clin Exp Ophthalmol 2024; 262:1765-1776. [PMID: 38231247 DOI: 10.1007/s00417-023-06361-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 12/12/2023] [Accepted: 12/27/2023] [Indexed: 01/18/2024] Open
Abstract
PURPOSE To investigate the distinct characteristics between young and elderly polypoidal choroidal vasculopathy (PCV) patients based on the pachy- or non-pachychoroid phenotypes. METHODS PCV patients treated with intravitreal injections of Conbercept based on the 3 + PRN regimen from 27 centers of China PCV Research Alliance were included. Patients were categorized into the young and the elderly aged group based on the cut-off point determined using the Youden method according to the pachychoroid phenotypes. The characteristics of past medical history, lifestyle factors, fundus manifestations, and treatment response between the subgroups were analyzed. RESULTS Three hundred eight eligible patients were included. Multivariate logistic regression showed a significant association between age and PCV subtype classification (OR = 0.921, P = 0.002). A cutoff age of 64.5 effectively distinguished between pachychoroid PCV and non-pachychoroid PCV (P < 0.001). Elderly PCV patients had a higher incidence of hypertension history (P = 0.044) but a lower incidence of diabetes history (P = 0.027). In terms of lifestyle, smoking history (P = 0.015) and staying up late (P = 0.004) were more significant in the young group of PCV patients. For clinical characteristics, the proportion of hemorrhagic PCV in the young group was significantly higher (P = 0.038), with a higher proportion of sharp-peaked PED (P = 0.049), thicker choroid (P < 0.001) but a lower portion of double-layer sign (P = 0.023) in OCT. Both groups showed significant anatomical changes compared to baseline in each follow-up period (P < 0.05), with the young group having a higher proportion of good anatomical response after the first injection (P = 0.009). CONCLUSION PCV patients stratified by subtype exhibit distinct characteristics between the young and elderly groups.

Abstract
We report the case of a 72-year-old white woman with blurring of vision in both eyes of 15 days' duration. She had a history of treatment for bilateral tuberculosis choroiditis 20 years before. She was diagnosed with polypoidal choroidal vasculopathy in the right eye and inflammatory choroidal neovascular membrane in the left eye, based on multimodal imaging, including optical coherence tomography, fundus fluorescein angiography, and indocyanine green angiography. The right eye received 3 intravitreal injections of aflibercept and showed complete resolution. The left eye was treated with a single intravitreal injection of aflibercept.

Abstract
PURPOSE The concentrations of cytokines in plasma may be different between neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV). We studied plasma levels of cytokines in patients with nAMD and PCV and compared them with control individuals. METHODS This was a prospective, clinic-based, case-control study of treatment-naive participants (n=49) with PCV (n=24), nAMD (n=11), and cataract controls (n=14). We sampled fresh venous blood and isolated plasma for analysis. Plasma concentrations of 34 angiogenic and inflammatory cytokines were determined by Luminex bead-based multiplex array. RESULTS After adjusting for gender and age using multivariate logistic analysis, we found that the plasma concentrations of monocyte chemoattractant protein-1, vascular endothelial growth factor (VEGF)-A, and VEGF-D significantly higher in both nAMD and PCV patients than those in controls (all P<0.05, times in nAMD: 3.5, 4.3, and 13.8, respectively, times in PCV: 4.1, 4.0, and 11.5, respectively). In contrast, the plasma concentration of platelet-derived growth factor-BB was significantly lower in nAMD and PCV patients than those in controls (all P<0.05, times in nAMD: 1.6, times in PCV: 1.7). The plasma levels of leukemia inhibitory factor in nAMD group were significantly higher compared with PCV group (P<0.0167). CONCLUSIONS Multiple cytokines involved in systemic inflammation and angiogenesis including monocyte chemoattractant protein-1, platelet-derived growth factor-BB, VEGF-A, and VEGF-D may contribute to the pathogenesis of nAMD and PCV. Measurement of leukemia inhibitory factor in the plasma may help differentiate nAMD from PCV. This finding suggests that the 2 disorders may have different molecular mechanisms, and additional longitudinal studies will be needed to determine whether these findings have clinical relevance to influence treatment algorithms or provide novel targets for medical therapy.

Association of HERPUD1 genetic variant rs2217332 with age-related macular degeneration and polypoidal choroidal vasculopathy in an Indian cohort. Graefes Arch Clin Exp Ophthalmol 2022; 261:1205-1212. [PMID: 36220983 DOI: 10.1007/s00417-022-05861-w] [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: 04/09/2022] [Revised: 09/16/2022] [Accepted: 10/03/2022] [Indexed: 11/04/2022] Open
Abstract
PURPOSE Age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) are sister diseases and have several similar clinical features and still have few genetic differences. The association of HERPUD1 (homocysteine inducible ER protein with ubiquitin like domain 1) gene variant rs2217332 with PCV is known; however, such association with AMD has not been reported in the Indian population. We analyzed the association of rs2217332 with PCV and AMD to identify the preferential association of this variant with these diseases. METHODS This is a population-based case-control study consisting of 422 patients (129 AMD cases; 101 PCV cases, 192 healthy controls) recruited from the vitreoretinal clinic Sankara Nethralaya. The sample size for the study was calculated using appropriate power calculation methods. Genotype was determined using PCR-based Sanger sequencing. The SPSS V23.0 statistical package tool was used to calculate chi-square and ROC to determine the association of rs2217332 with control, AMD, and PCV. RESULTS Here, we report for the first time the association of this genetic variant (rs2217332) with AMD and PCV in the Indian population. The case-control study shows a significant association of this SNP with PCV (P value = 0.002); however, this variant is not significantly associated with AMD (P value = 0.602). Comparison between AMD (as control) and PCV (as case) also showed significant association of the SNP with PCV (P value = 0.02). Minor allele A conferred to increase the risk of PCV. CONCLUSIONS The study concludes that the genetic variant rs2217332 in HERPUD1 gene is highly significantly associated with PCV and not with AMD in Indian populations.

Practical implementation of a q4-q16 aflibercept treat-and-extend pathway for the treatment of neovascular age-related macular degeneration: Updated guidance from a UK expert panel. Eye (Lond) 2022:10.1038/s41433-022-02264-3. [PMID: 36207506 PMCID: PMC9542445 DOI: 10.1038/s41433-022-02264-3] [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: 04/22/2022] [Revised: 08/24/2022] [Accepted: 09/14/2022] [Indexed: 11/09/2022] Open
Abstract
OBJECTIVES This report, based on guidance from a panel of UK retina specialists, introduces a revised intravitreal aflibercept (IVT-AFL) treat-and-extend (T&E) pathway for the treatment of neovascular age-related macular degeneration (nAMD). The T&E pathway incorporates the updated IVT-AFL label (April 2021) allowing flexible treatment intervals of 4 weeks to 16 weeks, after three initiation doses and a further dose after 8 weeks. Practical guidance is provided on the clinical implementation of the revised pathway, with the aim of supporting clinical decision-making to benefit patients and addressing capacity issues in nAMD services. METHODS Three structured round-table meetings of UK retina specialists were held online on 19 May, 16 June and 13 October 2021. These meetings were organised and funded by Bayer. RESULTS The authors revised the previously published consensus pathway to reflect the changes to the IVT-AFL label and developed guidelines for the implementation of the pathway in UK clinical practice. The guidelines include topics such as recommendations for extending patients with 2- or 4-week adjustments, extending patients to 16-week treatment intervals, managing fellow eye involvement, and reducing treatment intervals for patients with particularly active disease. CONCLUSIONS The revised IVT-AFL T&E nAMD pathway offers guidance to clinicians seeking to increase the dosing flexibility of IVT-AFL, with 4- to 16-week treatment intervals, in line with the updated IVT-AFL label, to meet the continually evolving demands of nAMD service provision.

Abstract
Polypoidal choroidal vasculopathy (PCV) is a common choroidal disease in the Asian population including Vietnam and is characterized by subretinal red-orange nodules, pigmented epithelium detachment, and massive subretinal hemorrhage. The recent focus on PCV in Vietnam can be attributed to advancements in PCV diagnosis and treatment. However, there is a scarcity of published literature and clinical data on PCV in the Vietnamese population, highlighting a key knowledge gap in this region. In order to address this gap, we gathered the opinions of experienced clinicians and retinal experts in Vietnam and reviewed available medical literature with the aim of: (i) providing an overview of PCV in the Vietnamese population—in terms of epidemiology, clinical characteristics, and management; (ii) tailoring international/national guidelines for the diagnosis and management of PCV, in line with available resources and medical equipment in Vietnam; and (iii) identifying gaps in clinical data in order to guide future PCV research in Vietnam and other countries with similar clinical conditions. The present review will enable healthcare providers and researchers to gain insight into current clinical practices and the limitations of PCV management in Vietnam and provide optimal and effective solutions.

Abstract
PurposeTo evaluate the diagnostic value of spectral-domain optical coherence tomography (SD-OCT) for polypoidal choroidal vasculopathy (PCV).MethodsA search of electronic databases was conducted from 2010 to 2021 to review the relevant literature on SD-OCT to identify PCV and other lesions causing serious or serosanguinous retinal pigment epithelial detachment (PED), specifically neovascular age-related macular degeneration (nvAMD). The QUADAS-2 scale was used to evaluate the quality of the literature. We performed a meta-analysis, including heterogeneity tests, analyze and synthesize the study data, meta-regression analysis, subgroup analysis, Fagan's plot, sensitivity analysis and publication bias tests.ResultsA total of 12 related studies involving 1,348 eyes were included in this study, and the random-effects model was used for meta-analysis. The results showed that the pooled sensitivity of SD-OCT in the diagnosis of PCV was 0.87 (95% CI: 0.84–0.89), the pooled specificity was 0.83 (95% CI: 0.80–0.86), and the pooled positive/negative likelihood ratios were 5.38 (95% CI: 3.28–8.80) and 0.16 (95% CI: 0.10–0.25), respectively. The diagnostic odds ratio (DOR) was 36.07 (95% CI: 15.98–81.40), and the area under the sROC curve (AUC) was 0.9429. When the pre–test probability was set at 20%, the post-test positive and negative probabilities were 58% and 4%, respectively. Meta-regression indicated that race was the primary source of heterogeneity (P <0.05). The Deeks' funnel plot showed no significant publication bias in this study (P>0.05).ConclusionSD-OCT has high sensitivity and specificity for the diagnosis of PCV, as well as significant clinical applicability. Since color fundus photography (CFP) is more clinically available and can improve the diagnostic efficacy, we recommend SD-OCT combined with CFP to diagnose PCV, especially without indocyanine green angiography (ICGA).Systematic Review Registrationhttps://inplasy.com/inplasy-2021-12-0048/, identifier: INPLASY2021120048.

Abstract
PURPOSE To describe the progression of pachychoroid neovasculopathy (PNV) into pachychoroid aneurysmal type 1 choroidal neovascularization (PAT1) / polypoidal choroidal vasculopathy (PCV). DESIGN Retrospective longitudinal cohort study. SUBJECTS Patients diagnosed with PNV with a follow-up of ≥ 2 years. METHODS Multimodal imaging, including optical coherence tomography and fluorescein and indocyanine green angiography, was reviewed for the presence of choroidal neovascularization (CNV), aneurysms within/at the margins of the CNV and sub-foveal choroidal thickness (SFCT). MAIN OUTCOME MEASURES Rate of PNV to PAT1/PCV conversion and risk factors thereof. RESULTS In total, 37 PNV eyes of 32 patients with a mean follow-up of 3.3±1.1 (2.0 - 5.2) years were included in the study. At PNV diagnosis, mean age was 59.7±8.7 (range: 38.5 - 78.0) years and mean SFCT was 357±92 (185 - 589) μm. During follow-up, 5 eyes (13.5 %) developed aneurysms after a mean 3.4±0.8 years (2.3 - 4.2 years) years, defining PAT1/PCV. Risk of PAT1/PCV conversion was 7.4 % at year 3, 13.6 % at year 4 and 30.7 % at year 5. Mean 5.2±4.0 to 8.1±3.4 intravitreal anti-VEGF injections were given per year, resulting in a significant reduction of SFCT to 317±104 (122 to 589) μm (p= 0.0007). Age at diagnosis of PNV was significantly lower in eyes that later went on to develop PAT1/PCV (54.0±5.6 (45.9 to 60.5) vs. 61.2±8.4 (38.5 - 78.0) years, p=0.025). At end of follow-up, SFCT had on average decreased by -14.0±17.6 (-55.9 to 23.1) % in the PNV group, while it had increased by mean 6.9±4.4 (0.00 to 10.8) % in the PAT1/PCV conversion group (p=0.0025). CONCLUSION PNV can develop aneurysms within its type 1 CNV, defining conversion to PAT1/PCV. In this study, conversion to PAT1/PCV was seen in 13.5 % of eyes, resulting in Kaplan Meier estimates of risk for conversion of 7.4 % at year 3, 13.6 % at year 4 and 30.7 % at year 5. Younger age at diagnosis of PNV and sustained choroidal thickening despite anti-VEGF therapy might be risk factors for PNV to progress into PAT1/PCV.

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.

Graefes Arch Clin Exp Ophthalmol 2022; 260:2249-2260. [PMID: 35133487 DOI: 10.1007/s00417-022-05583-z] [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: 10/05/2021] [Revised: 01/26/2022] [Accepted: 01/31/2022] [Indexed: 11/04/2022] Open
Abstract
PURPOSE To study serial changes in branching neovascular networks (BNN) by using optical coherence tomography angiography (OCTA) in patients with polypoidal choroidal vasculopathy (PCV) who underwent combined photodynamic therapy (PDT) and anti-vascular endothelial growth factor (anti-VEGF) therapy. METHODS In this retrospective study of 30 PCV patients who underwent combined therapy, OCTA images obtained at baseline and 1, 3, and 6 months after treatment were collected. The vessel area, vessel percentage area, average vessel length, and presence of polypoidal lesions on OCTA images as well as best-corrected visual acuity (BCVA), central retinal thickness (CRT), and central choroidal thickness (CCT) were recorded at each time point. RESULTS The BNN- and polypoidal lesion-detection rates on baseline OCTA images were 100% and 71%, respectively. The vessel area decreased during the first 3 months, and increased 6 months post-treatment, showing significant differences from baseline (p = 0.031). The vessel percentage area also reduced 1 and 3 months post-treatment (p = 0.025) and increased 6 months post-treatment. Continuous polypoidal lesion regression was observed from 1 to 3 and 6 months post-treatment (p = 0.031, p = 0.004, p = 0.002, respectively, in comparison with baseline). Patients with a decreasing vessel area over 6 months showed greater choroidal thickness than those with increasing vessel area (p = 0.004). CONCLUSIONS The BNN showed initial regression but were enlarged at 6 months after therapy. Patients showing continuous BNN regression showed a thicker choroid at baseline. This difference should be considered during treatment for PCV, and OCTA could be used for follow-up evaluations of PCV patients.

Polypoidal choroidal vasculopathy in pachychoroid: combined treatment with photodynamic therapy and aflibercept. Int Ophthalmol 2022; 42:601-610. [PMID: 35034223 DOI: 10.1007/s10792-021-02032-4] [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: 01/09/2021] [Accepted: 09/22/2021] [Indexed: 10/19/2022]
Abstract
INTRODUCTION To evaluate the effects of combined therapy using intravitreal Aflibercept (IVA) and photodynamic therapy (PDT) on polypoidal choroidal vasculopathy related to pachychoroid disease (PPCV). METHODS Patients with PPCV were treated with PDT combined with 3 IVA injections on a monthly basis, followed by pro re nata criteria. The 12-month follow-up consisted of multiple revaluations of visual acuity and SS-OCT parameters of clinical activity. RESULTS Nineteen eyes were included in the study; mean age was 65.5 years. Visual acuity improved after 12 months (0.35 ± 0.25 to 0.2 ± 0.20 logMAR, p = 0.005). Percentage of eyes with intraretinal and subretinal fluid reduced from baseline to the 12-month follow-up (from 52.6 to 10.5%, p = 0.12, and from 89.5 to 5.3% p = 0.0009, respectively). Central retinal and mean macular thicknesses reduced (258 ± 39.6 to 204.8 ± 38.8 μm p = 0.04 and 293.8 ± 32.1 to 248.1 ± 29.6 μm p = 0.017, respectively). Central choroidal and mean choroidal thicknesses also displayed a reduction (328.6 ± 54.9 to 289.8 ± 44.6 μm p = 0.001 and 314.5 ± 55.3 to 287.9 ± 47.6 μm p = 0.015, respectively). The mean number of injections was 4.6/year. CONCLUSION The results support the use of a combined therapy with Aflibercept and PDT in PPCV. This treatment would act in synergy, with anti-VEGF controlling exudation and PDT closing the aneurysmal vessel and reducing choroidal congestion.

Optimal approaches and criteria to treat-and-extend regimen implementation for Neovascular age-related macular degeneration: experts consensus in Taiwan. BMC Ophthalmol 2022; 22:25. [PMID: 35033037 PMCID: PMC8760882 DOI: 10.1186/s12886-021-02231-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Accepted: 12/23/2021] [Indexed: 11/12/2022] Open
Abstract
The management of neovascular age-related macular degeneration (nAMD) has taken a major stride forward with the advent of anti-VEGF agents. The treat-and-extend (T&E) approach is a refined management strategy, tailoring to the individual patient’s disease course and treatment outcome. To provide guidance to implementing anti-VEGF T&E regimens for nAMD in resource-limited health care systems, an advisory board was held to discuss and generate expert consensus, based on local and international guidelines, current evidence, as well as local experience and reimbursement policies. In the experts’ opinion, treatment of nAMD should aim to maximize and maintain visual acuity benefits while minimizing treatment burden. Based on current evidence, treatment could be initiated with 3 consecutive monthly injections. After the initial period, treatment interval may be extended by 2 or 4 weeks each time for the qualified patients (i.e. no BCVA loss ≥5 ETDRS letters and dry retina), and a maximum interval of 16 weeks is permitted. For patients meeting the shortening criteria (i.e. any increased fluid with BCVA loss ≥5 ETDRS letters, or presence of new macular hemorrhage or new neovascularization), the treatment interval should be reduced by 2 or 4 weeks each time, with a minimal interval of 4 weeks. Discontinuation of anti-VEGF may be considered for those who have received 2–3 consecutive injections spaced 16 weeks apart and present with stable disease. For these individuals, regular monitoring (e.g. 3–4 months) is recommended and monthly injections should be reinstated upon signs of disease recurrence.

Discovering the Potential of Natural Antioxidants in Age-Related Macular Degeneration: A Review. Pharmaceuticals (Basel) 2022; 15:ph15010101. [PMID: 35056157 PMCID: PMC8777838 DOI: 10.3390/ph15010101] [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: 12/09/2021] [Revised: 01/08/2022] [Accepted: 01/10/2022] [Indexed: 01/27/2023] Open
Abstract
Age-related macular degeneration (AMD) is a multifactorial disease associated with anatomical changes in the inner retina. Despite tremendous advances in clinical care, there is currently no cure for AMD. This review aims to evaluate the published literature on the therapeutic roles of natural antioxidants in AMD. A literature search of PubMed, Web of Science and Google Scholar for peer-reviewed articles published between 1 January 2011 and 31 October 2021 was undertaken. A total of 82 preclinical and 18 clinical studies were eligible for inclusion in this review. We identified active compounds, carotenoids, extracts and polysaccharides, flavonoids, formulations, vitamins and whole foods with potential therapeutic roles in AMD. We evaluated the integral cellular signaling pathways including the activation of antioxidant pathways and angiogenesis pathways orchestrating their mode of action. In conclusion, we examined the therapeutic roles of natural antioxidants in AMD which warrant further study for application in clinical practice. Our current understanding is that natural antioxidants have the potential to improve or halt the progression of AMD, and tailoring therapeutics to the specific disease stages may be the key to preventing irreversible vision loss.

Effect of intravitreal injection of bevacizumab in treated and untreated eyes of Black African patients with polypoidal choroidal vasculopathy. J Fr Ophtalmol 2021; 44:1505-1515. [PMID: 34776295 DOI: 10.1016/j.jfo.2021.06.012] [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: 03/30/2021] [Revised: 05/04/2021] [Accepted: 06/08/2021] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To evaluate the response of polypoidal choroidal vasculopathy (PCV) in eyes treated with intravitreal bevacizumab (BVZ) and untreated fellow eyes in black Africans. METHODS We studied 22 eyes (12 patients) divided into 12 treated and 10 untreated eyes from January 2017 to January 2020. Treated eyes received 1 monthly injection of BVZ 2.5mg for 3 months, with optional additional injections depending on the patient's course. Both groups of eyes were evaluated at presentation and then at 3, 6, 9, and 12 months after treatment. Outcome measures were visual acuity (VA) and ophthalmoscopic and OCT findings. RESULTS The mean age of the patients was 66.3±5.6 years. In treated eyes, VA remained stable from 0.10±0.12 at baseline to 0.20±0.30 at month 12, P=0.84. VA was stable in 83.3% and improved in 16.7% of eyes. On OCT, 41.7% of eyes showed decreased and another 41.7% disappearance of subretinal fluid (SRF) at 12 months. Pigment epithelial detachment (PED) height decreased in 9 eyes (75.0%) but remained unchanged in 3 eyes (25%). In untreated eyes, no difference was observed between the baseline (0.53±0.42) and 12-month VA (0.58±0.40), P=0.82. VA improved in 2 eyes, decreased in one eye, and remained unchanged in 7 eyes. OCT lesions remained stable in 6 eyes. The PED enlarged in one eye but remained stable in 3 other eyes. CONCLUSION Intravitreal injection of BVZ 2.5mg led to stabilization of VA, resorption of SRF, and reduction in the size of the PED in the majority of eyes with PCV but was ineffective on the polyps. The one-year prognosis in untreated eyes with PCV was favorable and marked by functional and structural stability.

Abstract
Recent advances in retinal imaging technology have improved our understanding in the pathogenesis and evolvement of various chorioretinal diseases. Central serous chorioretinopathy and polypoidal choroidal vasculopathy are now recognized to belong to the same spectrum of disorders known as pachychoroid diseases. Pachychoroid diseases have similar pathogenesis pathway and common characteristics of thickened choroid, dilated outer choroidal vessels, and thinning of choriocapillaris. More disease entities have been identified to belong to this disease spectrum. Photodynamic therapy can induce choroidal hypoperfusion, remodeling of abnormal choroidal vessels, and reduction of choroidal congestion. It is known to be an effective treatment for chronic central serous chorioretinopathy and polypoidal choroidal vasculopathy. Many new studies are being performed to investigate its efficacy in other pachychoroid diseases. In this review, we provided an overview of the rationale, efficacy, and treatment strategies of photodynamic therapy in different pachychoroid diseases and discussed its role in the management along with other treatment modalities with most updated clinical evidence.

Abstract
Purpose: To compare the clinical effects of postoperative versus perioperative injection of anti-vascular endothelial growth factor (VEGF) drugs before and after pars plana vitrectomy (PPV) in patients with vitreous hemorrhage secondary to polypoidal choroidal vasculopathy (PCV). Methods: This was a retrospective study of patients who underwent PPV due to vitreous hemorrhage between October 2013 and June 2019 at Ningbo Eye Hospital. The patients who underwent PPV surgery due to PCV-secondary vitreous hemorrhage were included. The primary outcome was the changes in best-corrected visual acuity. The secondary outcome was the central macular thickness. Results: Compared with the postoperative group (n = 20), the perioperative group (n = 18) showed a smaller number of postoperative anti-VEGF injections (5.1 ± 0.8 vs. 8.0 ± 1.5, P < 0.05) and lower frequencies of early hyphema (5.6% vs. 30.0%, P < 0.05), and recurrent vitreous hemorrhage (11.1% vs. 30.0%, P < 0.05). The logarithm of minimal angle resolution (LogMAR) was smaller in the perioperative group compared with the postoperative group at 1 week, 1 month, and 3 months after PPV (P < 0.05), but there were no differences thereafter. Compared with the postoperative group, the perioperative group had thinner fovea at 1 week, 1 month, and 3 months (P < 0.05), but the differences disappeared after 3 months. Conclusion: In patients with PCV and vitreous hemorrhage, compared with postoperative anti-VEGF, perioperative anti-VEGF could reduce the difficulty of surgery and reduce the occurrence of postoperative complications, but there were no differences in long-term vision and macular thickness after surgery.

Comparison of visual outcomes between therapy choices and subtypes of polypoidal choroidal vasculopathy (PCV) in Taiwan: a real-world study. Sci Rep 2021; 11:470. [PMID: 33432090 PMCID: PMC7801625 DOI: 10.1038/s41598-020-80731-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Accepted: 12/21/2020] [Indexed: 11/30/2022] Open
Abstract
Polypoidal choroidal vasculopathy (PCV) is a distinctive type of neovascular age-related macular degeneration prevalent in many Asian countries. However, there is still some controversy in how the subtypes of PCV are classified. This post-hoc study redefined the branching vascular network (BVN) and PCV subtypes through retrospective review of indocyanine green angiography (ICGA) and fluorescein angiography images from two observational studies (RENOWNED/REAL). Of the visual outcomes for each angiographic subtype and treatment pattern investigated, BVN was identified in 56.3% of PCV patients. The proportions and features of the re-defined PCV subtypes were 43.8%, 10.4%, and 45.8% for subtype A (without distinctive features of BVN), B (with BVN but no leakage), and C (with BVN and leakage), respectively. Subtype A had better visual outcomes when compared to subtype C. This possibly resulted from a better baseline visual acuity in subtype A. Moreover, combination therapy [photodynamic therapy plus anti-vascular endothelial growth factor (VEGF)] may lead to better visual improvement than mono-anti-VEGF treatment alone. This study provides the prevalence of PCV subtypes in Taiwan and may serve as a reference for PCV treatment strategies in a real-world setting, especially for the combination therapy and patients without distinctive features of BVN.

Abstract
PURPOSE To evaluate the functional and structural outcomes of intravitreal conbercept monotherapy using a "3 + pro re nata (PRN)" regimen in treatment-naïve subjects with polypoidal choroidal vasculopathy (PCV) up to 12 months. METHODS Thirty subjects (30 eyes) with PCV participated in this interventional, retrospective study. All subjects received intravitreal injections of 0.5 mg (0.05 ml) conbercept using a "3 + PRN" regimen for 12 months. The changes in best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) parameters, polyp lesion area, and regression rate were evaluated at baseline, month 3, and month 12. RESULTS At the study end-point, BCVA improved significantly from 52.80 ± 17.17 ETDRS letters at baseline to 62.20 ± 18.96 letters (P < 0.001), with a mean gain of 9.40 ± 14.97 letters. The central retinal thickness (CRT) significantly reduced from 454.93 ± 147.31 μm at baseline to 308.73 ± 106.80 μm (P < 0.001) at end-point, and the total macular volume (TMV) decreased from 9.51 ± 1.04 mm3 at baseline to 8.32 ± 0.84 mm3 at end-point (P < 0.001). The mean volume of pigment epithelial detachment (PED) decreased from 0.73 ± 0.97 mm3 at baseline to 0.48 ± 0.71 mm3 (P < 0.05) at month 3. At month 12, the mean volume of PED was 0.57 ± 0.80 mm3 (P > 0.05 compared to baseline). After the 3-monthly loading injections, 6 eyes (20.0%) showed complete polyp regression, whereas a total of 19 eyes (63.5%) showed complete regression at month 12. The average injections given per subject were 7.70 ± 1.81. CONCLUSION Intravitreal conbercept using the "3 + PRN" regimen was effective in the treatment of PCV.

Abstract
We report a case of optic disc drusen (ODD) associated with peripapillary polypoidal choroidal vasculopathy (PCV). A 62-year-old Malay lady presented with both eye ODD and the left eye associated with peripapillary subretinal hemorrhage. Ultrasound B-scan and red-free photography confirmed the optic nerve head drusen findings bilaterally. Optical coherence tomography (OCT) of the left eye showed sharply elevated peripapillary pigment epithelial detachment with subretinal fluid. The presence of peripapillary polyps with branching vascular network in indocyanine green angiography of the left eye further confirmed the diagnosis of PCV and excluded choroidal neovascularization (CNV) secondary to ODD. Subsequently, the patient was treated with a combination of verteporfin photodynamic therapy with three monthly intravitreal ranibizumab injections. Three months after the combined treatment, OCT showed completely resolved subretinal fluid. ODD can cause compression of the subretinal vessels at the optic disc that results in retinal ischemia and release of vascular endothelial growth factor, which may trigger the development of CNV or PCV. The rarity of this combination makes it interesting to study more cases of ODD with PCV. Importantly, a thorough evaluation in distinguishing the PCV from the CNV that mimics it is crucial for early detection and prompt intervention. In this case, indocyanine green angiography (ICGA) is the diagnostic method to differentiate the PCV from CNV secondary to ODD.

Aim To describe optical coherence tomography angiography (OCTA) features of polypoidal choroidal neovascularisation (PCNV) secondary to age-related macular degeneration. Methods A retrospective consecutive series of 51 patients with a diagnosis of PCNV, based on clinical and multimodal imaging, was analysed. All patients with PCNV underwent a comprehensive ophthalmological examination, including fluorescein and indocyanine green angiography, structural optical coherence tomography (OCT) and OCTA. Two blinded retinal specialists carefully reviewed OCTA slabs in order to assess the morphological patterns of PCNV lesions. Furthermore, fractal analysis of PCNV en face images on OCTA, including vascular perfusion density (VPD), fractal dimension (FD) and lacunarity (LAC), was performed. Results Fifty-one PCNV eyes were included in the study. In all, the branching vascular network appeared hyper-reflective. Polyps showed two different patterns: in 34/51 (67%) eyes, they corresponded to hypo-reflective structures, whereas in the remaining 17 (33%) eyes, they appeared as hyper-reflective lesions. In all PCNV eyes, mean VPD, FD and LAC were 0.76±0.17%, 1.46±0.12 and 2.4±0.87, respectively. No significant difference was found between PCNVs showing a different OCTA pattern, in terms of quantitative OCTA parameters. Conclusion Fractal analysis provides quantitative parameters demonstrating that PCNVs with different OCTA patterns share the same neovascular architecture and branching complexity. These new findings improve our ability to interpret OCTA slabs, opening new areas of discussion about this type of neovascular lesion.

Efficacy and Treatment Burden of Intravitreal Aflibercept Versus Intravitreal Ranibizumab Treat-and-Extend Regimens at 2 Years: Network Meta-Analysis Incorporating Individual Patient Data Meta-Regression and Matching-Adjusted Indirect Comparison. Adv Ther 2020; 37:2184-2198. [PMID: 32222903 PMCID: PMC7467478 DOI: 10.1007/s12325-020-01298-x] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2020] [Indexed: 03/02/2023]
Abstract
Purpose To compare visual outcomes and treatment burden between intravitreally administered aflibercept (IVT-AFL) and ranibizumab (RBZ) treat-and-extend (T&E) regimens in patients with wet age-related macular degeneration (wAMD) at 2 years. Methods A systematic literature review was carried out in Medline, EMBASE, and CENTRAL in October 2018. Matching-adjusted indirect comparison (MAIC) and/or individual patient data meta-regression was used to connect ALTAIR (assessing IVT-AFL T&E) with other studies, adjusting for between-trial differences in baseline visual acuity and age or baseline visual acuity, age, and polypoidal choroidal vasculopathy (PCV) status. Sensitivity analyses were conducted to test the robustness of the results, including direct MAIC between IVT-AFL T&E (ALTAIR) and RBZ T&E (CANTREAT and TREX-AMD trials). Results Six randomized controlled trials (RCTs) (ALTAIR, VIEW 1 and 2, CATT, CANTREAT, and TREX) were included in the analysis. IVT-AFL T&E was assessed in one study, ALTAIR (n = 255), while RBZ T&E was assessed in two trials (n = 327). At 2 years, the median difference (95% credibility interval) between IVT-AFL T&E and RBZ T&E regarding the numbers of Early Treatment Diabetic Retinopathy Study (ETDRS) letters gained was not significant (M1: − 2.29 [− 8.10, 3.58]; M2: − 0.55 [− 6.34, 5.29]). IVT-AFL T&E was associated with significantly fewer injections than RBZ-T&E (M1: − 6.12 [− 7.60, − 4.65]; M2: − 5.93 [− 7.42, − 4.45]). Results of the sensitivity analyses were consistent with the main scenarios. Conclusion Patients with wAMD receiving an IVT-AFL T&E regimen achieved and maintained improvement in visual acuity with fewer injections over 2 years compared with RBZ T&E. IVT-AFL T&E may therefore serve as the optimal therapy for wAMD, as it was associated with clinical efficacy and minimized treatment burden.

Abstract
Photodynamic therapy (PDT) using verteporfin (Visudyne®; Bausch + Lomb) is a treatment that is widely used to elicit cell and tissue death. In ophthalmology, PDT targets choroidal vascular abnormalities and induces selective occlusion of vessels. PDT was originally used in combination with full-dose verteporfin to treat neovascular age-related macular degeneration. Since the introduction of treatment with vascular endothelial growth factor receptor inhibitors, the clinical targets of PDT have shifted to other chorioretinal conditions, such as central serous chorioretinopathy, polypoidal choroidal vasculopathy, and choroidal hemangioma. In recent years, clinical studies have facilitated the optimization of treatment outcomes through changes in protocols, including the introduction of reduced treatment settings, such as PDT with half-dose verteporfin and half-fluence PDT. Here, we review PDT and its use for chorioretinal diseases from a practical perspective.

Abstract
PURPOSE To investigate the diagnostic accuracy of noninvasive multimodal imaging methods in diagnosing polypoidal choroidal vasculopathy (PCV) and distinguishing PCV from typical neovascular age-related macular degeneration (nvAMD). METHODS Retrospective study. Imaging features of noninvasive multimodal imaging methods, including fundus photography (FP), B-scan optical coherence tomography (OCT), en face OCT, OCT angiography, and autofluorescence, of 103 eyes with PCV or typical nvAMD were reviewed. Diagnostic strategy was established based on imaging features and was validated in other 105 eyes with PCV or typical nvAMD. RESULTS Features of subretinal orange nodule on FP, thumb-like PED on OCT, notched PED on OCT, bubble sign on OCT, and Bruch's membrane depression under serosanguinous PED on OCT were more common. When the diagnostic strategy of using at least 2 of 5 features was performed, there is 0.88 sensitivity and 0.92 specificity for diagnosing PCV. The results of the validation test further confirmed the diagnostic strategy with 0.94 sensitivity and 0.93 specificity. CONCLUSIONS Noninvasive multimodal imaging, especially FP and B-scan OCT, provide high sensitivity and specificity for diagnosing PCV and distinguishing PCV from typical nvAMD, when at least 2 of 5 suggestive imaging features are present.
