[PMID: 38929795 PMCID: PMC11204593 DOI: 10.3390/jpm14060574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2024] [Revised: 05/13/2024] [Accepted: 05/24/2024] [Indexed: 06/28/2024] Open
Abstract
Purpose: To investigate the associations between fluid accumulation at different levels in the retina and visual outcome in polypoidal choroidal vasculopathy (PCV). Design: A retrospective observational study. Institutional setting. Study Population: A total of 91 eyes from 91 patients of PCV were included, with 65 receiving intravitreal aflibercept monotherapy and 26 receiving combined intravitreal ranibizumab and photodynamic therapy (PDT). Observation Procedures: Best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) examination results were recorded at baseline and 3, 6, and 12 months after treatment. Main Outcome Measures: The correlations between visual outcomes and fluid biomarkers including intraretinal fluid (IRF), subretinal fluid (SRF), serous pigment epithelium detachment (PED), and hemorrhage at fovea were analyzed. Results: No differences in treatment outcomes were noted between patients receiving aflibercept and those receiving combined ranibizumab and PDT. IRF and hemorrhage at baseline predicted poorer vision at 3, 6, and 12 months. The presence of IRF was associated with poorer vision at 6 months and 12 months (p < 0.05 for all). The presence of SRF or PED was not associated with better vision at any time point. No differences in the correlations between fluid markers and visual outcomes were noted between thin and thick subfoveal choroidal thickness groups. Conclusions: For PCV, IRF and hemorrhage at baseline served as surrogates for poor visual prognosis after treatment, and IRF was a biomarker for poor vision during the treatment course. No fluid markers predicted good visual prognosis or had a positive impact on vision at any time point.

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. [PMID: 34678176 DOI: 10.1016/j.jcjo.2021.09.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Revised: 08/03/2021] [Accepted: 09/17/2021] [Indexed: 11/23/2022]
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.

Progression of Polypoidal Lesions Associated with Exudative Recurrence in Polypoidal Choroidal Vasculopathy. Ophthalmology 2023; 130:167-178. [PMID: 36152843 DOI: 10.1016/j.ophtha.2022.09.013] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 08/31/2022] [Accepted: 09/12/2022] [Indexed: 01/25/2023] Open
Abstract
PURPOSE To investigate the characteristics of the branching vascular network (BVN) and polypoidal lesions in polypoidal choroidal vasculopathy (PCV) to determine near-term indicators that may predict exudative recurrence. DESIGN Retrospective cohort study. PARTICIPANTS Patients with PCV receiving anti-vascular endothelial growth factor (VEGF) monotherapy or anti-VEGF plus photodynamic therapy were followed for at least 1 year using swept-source OCT angiography (SS-OCTA) imaging. METHODS Patients were divided into 2 groups based on whether exudative recurrence occurred during follow-up. Multiple parameters were collected and compared between the 2 groups, such as age, gender, visual acuity, number of polypoidal lesions, lesion area at the first SS-OCTA visit, and total lesion area change from the first SS-OCTA visit to the last SS-OCTA visit. To evaluate the association between SS-OCTA imaging-based risk factors and the exudative recurrences, imaging features associated with PCV such as BVN growth and polypoidal lesion progression (enlargement, new appearance, and reappearance) at each follow-up visit were analyzed. The time intervals from the nonexudative visit with lesion progression to the corresponding exudative recurrence visit were documented to explore their association with exudative recurrences. Cox regression and logistic regression analyses were used. MAIN OUTCOME MEASURES Association between BVN growth and polypoidal lesion progression with exudative recurrence. RESULTS Thirty-one eyes of 31 patients (61% men) were included. Sixteen eyes had no recurrence of exudation, and 15 eyes had recurrence during follow-up. The average follow-up duration was 20.55 ± 6.86 months (range, 12-36 months). Overall, the recurrence group had worse best-corrected visual acuity (P = 0.019) and a greater increase in lesion area (P = 0.010). Logistical regression analysis showed that polypoidal lesion progression, including new appearance, enlargement, and reappearance of polypoidal lesions, was associated with exudative recurrences within 3 months (odds ratio, 26.67, 95% confidence interval, 3.77-188.54, P = 0.001). CONCLUSIONS Growth of nonexudative BVN and progression of polypoidal lesions were found to be lesion characteristics associated with exudative recurrences, and progression of polypoidal lesions might serve as a stand-alone indicator for the near-term onset of exudation. In PCV, more frequent follow-up visits are recommended when polypoidal lesions show progression.

Huang WL, Hsia Y, Wang SW, Hung KC, Huang CJ, Chen MS, Ho TC. Characteristics and treatment response of polypoidal choroidal vasculopathy in highly myopic eyes. Eye (Lond) 2022:10.1038/s41433-022-02251-8. [PMID: 36207505 DOI: 10.1038/s41433-022-02251-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Revised: 08/15/2022] [Accepted: 09/07/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND To compare the characteristics and treatment responses of polypoidal choroidal vasculopathy (PCV) between highly myopic and non-highly myopic eyes. METHODS This retrospective cohort study included patients diagnosed with PCV at the clinic of National Taiwan University Hospital between 2013 and 2019. The diseased eyes were grouped per refractive error and axial length at diagnosis. Imaging data were used to retrieve the PCV characteristics, and electronic medical records were used to retrieve the treatment responses. RESULTS Among 116 eyes with PCV, 11 eyes of 10 patients were highly myopic; seven of these patients were women. All highly myopic eyes showed a thin subfoveal choroid, while three eyes had a pachychoroid phenotype with significant focal choroidal thickening. After treatment with either intravitreal anti-vascular endothelial growth factor (VEGF) injections, photodynamic therapy (PDT), or both, best-corrected visual acuity was better in the high-myopia group at 1 year. Visual acuity at presentation and the presence of feeder vessels were found to be predictors of the visual outcome. CONCLUSIONS In this study we reported, to the best of our knowledge, the largest cohort of PCV in highly myopic eyes to date. Female predominance, lower incidence of subretinal haemorrhage, and a thin choroid with a focal pachychoroid phenotype were found to characterise PCV in highly myopic eyes. Visual acuity transiently improved after either anti-VEGF monotherapy or combination therapy with PDT.

Quantitative analysis of branching neovascular networks in polypoidal choroidal vasculopathy by optical coherence tomography angiography after photodynamic therapy and anti-vascular endothelial growth factor combination therapy. 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.

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.

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.

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.

[PMID: 34274193 DOI: 10.1016/j.jfma.2021.06.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 04/20/2021] [Accepted: 06/18/2021] [Indexed: 11/22/2022] Open
Abstract
Neovascular age-related macular degeneration (nAMD) is a leading cause of irreversible vision loss. The present consensus provides suggestions on diagnosis, evaluation, treatment, and follow-up strategies for nAMD from a panel of 11 practicing ophthalmologists. The experts suggest that the baseline visit for nAMD management should include a comprehensive ophthalmologic examination via a multimodal approach consisting of visual and anatomical evaluation. Patients diagnosed with nAMD should be subjected to treatment with the goal of maintaining visual function while diminishing anatomical disease activity and minimizing treatment burden. Currently, anti-VEGF therapy is the main treatment strategy for nAMD, and evaluation involving comprehensive ophthalmologic examination within 1 month of completion of the loading phase comprising three monthly injections is recommended to guide subsequent management. Either a treat-and-extend or pro re nata regimen can be considered for the maintenance phase of anti-VEGF therapy, and the regimen should be chosen and adjusted according to disease activity, reimbursement criteria, financial burden, and patient preferences. In the event of inactive nAMD or poor treatment outcomes, after thorough evaluation and patient education, anti-VEGF therapy may be stopped. The consensus provides practical nAMD management guidelines for ophthalmologists and fellow healthcare professionals.

To provide real-world experiences of treating polypoidal choroidal vasculopathy (PCV) patients with photodynamic therapy (PDT) plus intravitreal injection of ranibizumab or intravitreal injection of aflibercept alone. Retrospective chart review of patients with PCV in a single tertiary referral center in Taiwan. Chart review of PCV patients treated with PDT and injection of ranibizumab or injection of aflibercept. A total of 101 eyes of 101 patients (38 females and 63 males) were reviewed. Of those, 48 and 53 eyes received primary/adjunctive PDT along with injections of ranibizumab or intravitreal injections of aflibercept only, respectively. Initial visual acuity (VA) and central subfield choroidal thickness were similar between the two groups (p > 0.05). In addition, changes in VA at 3, 6, and 12 months post treatment were similar. The central retinal thickness decreased with either treatment (p < 0.01); however, this change did not translate into VA performance (p > 0.05). In the subgroup analysis of pachychoroid and non-pachychoroid patients, better initial VA and post-treatment VA at 3 months and 6 months was noted in the latter group of patients treated with anti-vascular endothelial growth factor monotherapy (p < 0.05). Aflibercept monotherapy is comparable with PDT plus ranibizumab in PCV patients with PCV (pachychoroid and non-pachychoroid patients). In addition, better prognosis regarding VA was observed in non-pachychoroid patients treated with aflibercept monotherapy.

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.
