Abstract
PURPOSE To investigate age-specific prevalence of disease subtypes and baseline best-corrected visual acuity (BCVA) in Japanese patients with treatment-naïve neovascular age-related macular degeneration (nAMD). STUDY DESIGN Retrospective multicenter case series. METHODS We reviewed the records of patients with treatment-naïve nAMD who underwent initial treatment in 14 institutions in Japan sometime during the period from 2006 to 2015. In patients in whom both eyes were treated, only the eye treated first was included for analysis. The patients were stratified by age for the analysis. RESULTS In total, 3096 eyes were included. The overall prevalence of subtypes was as follows: typical AMD, 52.6%; polypoidal choroidal vasculopathy (PCV), 42.8%; retinal angiomatous proliferation (RAP), 4.6%. The number of eyes in each age group was as follows: younger than 60 years, 199; 60s, 747; 70s, 1308; 80s, 784; 90 years or older, 58. The prevalence of typical AMD in each age group was 51.8%, 48.1%, 52.1%, 57.7%, and 55.2%, respectively. The prevalence of PCV was 46.7%, 49.1%, 44.7%, 34.4%, and 19.0%, respectively. The prevalence of RAP was 1.5%, 2.8%, 3.2%, 7.9%, and 25.9%, respectively. The prevalence of PCV decreased with age, whilst that of RAP increased. The prevalence of RAP was higher than that of PCV in patients aged 90 years or older. The mean baseline BCVA (logMAR) was 0.53. In each age group, the mean baseline BCVA was 0.35, 0.45, 0.54, 0.62, and 0.88, respectively. The mean logMAR BCVA at baseline significantly worsened with age (P < 0.001). CONCLUSION The prevalence of nAMD subtypes differed according to age in Japanese patients. The baseline BCVA worsened with age.

Polypoidal Choroidal Vasculopathy Based on Non-ICGA Criteria in White Patients With Neovascular Age-Related Macular Degeneration. Am J Ophthalmol 2022; 244:58-67. [PMID: 35952753 DOI: 10.1016/j.ajo.2022.07.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Revised: 07/23/2022] [Accepted: 07/25/2022] [Indexed: 01/30/2023]
Abstract
PURPOSE To determine prevalence of probable polypoidal choroidal vasculopathy (PCV) among White patients with neovascular age-related macular degeneration (nAMD) using non-indocyanine green angiography (ICGA) criteria DESIGN: Multicenter, multinational, retrospective, cross-sectional study. METHODS A total of 208 treatment-naive eyes from Hispanic and non-Hispanic White individuals diagnosed with nAMD were included. All underwent color fundus photography (CFP), optical coherence tomography (OCT), and fluorescein angiography (FFA). De-identified images of study eyes were sent to 2 groups of graders. Group 1 reviewed CFP, OCT, and FFA to confirm nAMD diagnosis. Group 2 reviewed CFP and OCT to determine highly suggestive features for PCV. Probable PCV diagnosis defined as the presence of ≥2 of 4 highly suggestive features for PCV: notched or fibrovascular pigment epithelial detachment (PED) on CFP, sharply-peaked PED, notched PED, and hyperreflective ring on OCT. RESULTS Eleven eyes were excluded because of poor image quality (6) or non-nAMD diagnosis (5). Of 197 eligible eyes (197 patients), the mean age (SD) was 78.8 years (8.9), 44.2% were men, 26.4% were Hispanic, and 73.6% were non-Hispanic White individuals; 41.1%, 23.4%, 9.1%, and 2.5% had ≥1, ≥2, ≥3, and 4 highly suggestive features. Results showed that 23.4% (95% CI, 17.6%-29.9%) had probable PCV diagnosis. Predominantly occult CNV was more frequently found in probable PCV than nAMD subgroup (84.8% vs 64.9%, P = .01). Hispanic White individuals had a lower prevalence of probable PCV than non-Hispanic White individuals (9.6% vs 28.2%, P = .006) CONCLUSIONS: These findings suggest that probable PCV occurs between 17.6% and 29.9% in White individuals with nAMD, and more commonly in non-Hispanic than in Hispanic White individuals.

Characterisation of macular neovascularisation subtypes in age-related macular degeneration to optimise treatment outcomes. Eye (Lond) 2022:10.1038/s41433-022-02231-y. [DOI: 10.1038/s41433-022-02231-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Revised: 07/24/2022] [Accepted: 08/30/2022] [Indexed: 11/09/2022] Open
Abstract
AbstractThe aim of this review is to identify the common characteristics and prognoses of different subtypes of neovascular age-related macular degeneration (nAMD). We also propose recommendations on how to tailor treatments to the subtype of neovessels to optimise patient outcomes. The authors, selected members of the Vision Academy, met to discuss treatment outcomes in nAMD according to macular neovascularisation (MNV) subtypes, using evidence from a literature search conducted on the PubMed database (cut-off date: March 2019). This review article summarises the recommendations of the Vision Academy on how the characterisation of MNV subtypes can optimise treatment outcomes in nAMD. The identification of MNV subtypes has been facilitated by the advent of multimodal imaging. Findings from fluorescein angiography, indocyanine green angiography and spectral-domain optical coherence tomography collectively help refine and standardise the determination of the MNV subtype. To date, three subtypes have been described in the literature and have specific characteristics, as identified by imaging. Type 1 MNV is associated with better long-term outcomes but usually requires more intense anti-vascular endothelial growth factor dosing. Type 2 MNV typically responds quickly to treatment but is more prone to the development of fibrotic scars, which may be associated with poorer outcomes. Type 3 MNV tends to be highly sensitive to anti-vascular endothelial growth factor treatment but may be associated with a higher incidence of outer retinal atrophy, compared with other subtypes. Accurately assessing the MNV subtype provides information on prognosis and helps to optimise the management of patients with nAMD.

Abstract
PURPOSE Differences in multimodal imaging features between Asian and Caucasian eyes may contribute to our understanding of the etiology of the polypoidal choroidal vasculopathy (PCV). The purpose of this study was to compare the multimodal imaging features of Asian and Caucasian eyes with PCV. DESIGN Cross-sectional, retrospective, multicenter, observational case series. METHODS Consecutive treatment-naïve patients diagnosed with PCV based on indocyanine green angiography in accordance with published guidelines. Demographic and multimodal imaging findings based on color fundus photography, spectral domain optical coherence tomography, fluorescein angiography, and indocyanine green angiography were graded. RESULTS A total of 250 participants with PCV (128 Asian vs 122 Caucasian participants) were included. Asian participants presented with lower best-corrected visual acuity (mean ± SD: 0.7 ± 0.6 logMAR vs 0.4 ± 0.3 logMAR; P < .001) compared with Caucasian participants. More Asian eyes had subretinal hemorrhage (mean ± SD: 53.9% vs 24.6%; P < .001) and larger areas of hemorrhage (mean ± SD: 7.5 ± 15.2 mm2 vs 1.3 ± 3.3 mm2; P < .001). More Asian eyes had pachyvessels (84.4% vs 28.7%; P < .001), choroidal vascular hyperpermeability (70.3% vs 17.2%; P < .001), and widespread polypoidal lesions (19.5% vs 8.2%; P = .005), and Caucasian eyes had more drusen (79.5% vs 49.2%; P = .02). CONCLUSIONS Multimodal imaging analysis revealed ethnic differences in disease characteristics of PCV, suggesting pathophysiologic mechanism of the disease vary based on ethnicity.

Abstract
Purpose To compare the efficacy and safety of brolucizumab versus aflibercept in eyes with polypoidal choroidal vasculopathy (PCV) over 96 weeks in the HAWK study. Design HAWK was a global, 2-year, randomised, double-masked, multicentre phase III trial in participants with neovascular age-related macular degeneration. Methods Of the Japanese participants with PCV, 39 received brolucizumab 6 mg and 30 received aflibercept 2 mg. After 3 monthly loading doses, brolucizumab-treated eyes received an injection every 12 weeks (q12w) but were adjusted to q8w if disease activity was detected. Aflibercept-treated eyes received fixed q8w dosing. Mean change in best-corrected visual acuity (BCVA), the proportion of participants on q12w, retinal thickness, retinal fluid changes and safety were assessed to Week 96. Results Mean change in BCVA (early treatment diabetic retinopathy study (ETDRS) letters) from baseline to week 48/week 96 was+10.4/+11.4 for brolucizumab and +11.6/+11.1 for aflibercept. For brolucizumab-treated eyes, the probability of only q12w dosing after loading through week 48 was 76%, and 68% through week 96. Fluid resolution was greater with brolucizumab than aflibercept: respective proportions of eyes with intraretinal fluid and/or subretinal fluid were 7.7% and 30% at week 48% and 12.8% and 16.7% at week 96. Brolucizumab exhibited an overall well-tolerated safety profile despite a higher rate of intraocular inflammation compared with aflibercept. Conclusion In Japanese eyes with PCV, brolucizumab q12w/q8w monotherapy resulted in robust and consistent BCVA gains that were comparable to q8w aflibercept dosing. Anatomical outcomes favoured brolucizumab over aflibercept, with 76% of brolucizumab participants maintained on q12w dosing after loading to week 48.

[PMID: 34022443 DOI: 10.1016/j.oret.2021.05.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 05/05/2021] [Accepted: 05/07/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE Although polypoidal choroidal vasculopathy (PCV) is best diagnosed with indocyanine green angiography (ICGA), ICGA is often unavailable or not ordered. OCT is widely available, and OCT B-scan can visualize polypoidal lesions diagnostic of PCV as inverted U-shaped elevations of the retinal pigment epithelium (RPE) with heterogeneous reflectivity and sometimes ring-shaped lesions within the polypoidal lesion. This study aims to differentiate findings between eyes diagnosed with PCV or typical exudative age-related macular degeneration (AMD) using ICGA and then compares findings noted on the OCT B-scan line scan in each group. DESIGN Retrospective, chart review. METHODS Clinical features of eyes with PCV and typical exudative AMD were compared by using ICGA. Eyes with PCV were evaluated for inverted U-shaped polypoidal lesions, which are the main differentiating finding of PCV from typical exudative AMD. Data collected included presence of subretinal fluid (SRF), macular edema or intraretinal edema, subretinal hyperreflective material (SHRM), and retinal pigment epithelial detachment (RPED). These findings were evaluated in 2 parts: baseline and after 6 to 9 months of antiangiogenic therapy. Additionally, analysis was performed for the presence of polypoidal lesions before and after treatment. MAIN OUTCOME MEASURES Presence of inverted U-shaped lesions on OCT B-scan following treatment. RESULTS A total of 112 eyes of 106 patients were included. A total of 69 eyes were diagnosed with PCV, and 43 eyes were diagnosed with typical exudative AMD. Compared with AMD eyes, PCV eyes had an increased prevalence of SRF at baseline and after 6 to 9 months of treatment, but the prevalence of macular edema, SHRM, and RPED was similar at baseline and at 6 to 9 months after treatment. In PCV eyes, the presence of visible polypoidal lesions decreased from 56.5% to 24.6% after treatment. CONCLUSIONS If PCV is suspected in an anti-vascular endothelial growth factor (VEGF)-resistant case of exudative AMD, in the absence of ICGA availability, it is important to look at the baseline OCT B-scan before therapy for evidence of polypoidal lesions. The characteristic inverted U-shaped elevation was present in more than half of PCV eyes on OCT B-scan at baseline but disappeared after antiangiogenic therapy in 56.4% of cases in which this was initially identified. Subretinal fluid was more prevalent in PCV eyes than non-PCV AMD eyes.

Incomplete response to Anti-VEGF therapy in neovascular AMD: Exploring disease mechanisms and therapeutic opportunities. Prog Retin Eye Res 2020; 82:100906. [PMID: 33022379 PMCID: PMC10368393 DOI: 10.1016/j.preteyeres.2020.100906] [Citation(s) in RCA: 149] [Impact Index Per Article: 37.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 09/18/2020] [Accepted: 09/22/2020] [Indexed: 12/13/2022]
Abstract
Intravitreal anti-vascular endothelial growth factor (VEGF) drugs have revolutionized the treatment of neovascular age-related macular degeneration (NVAMD). However, many patients suffer from incomplete response to anti-VEGF therapy (IRT), which is defined as (1) persistent (plasma) fluid exudation; (2) unresolved or new hemorrhage; (3) progressive lesion fibrosis; and/or (4) suboptimal vision recovery. The first three of these collectively comprise the problem of persistent disease activity (PDA) in spite of anti-VEGF therapy. Meanwhile, the problem of suboptimal vision recovery (SVR) is defined as a failure to achieve excellent functional visual acuity of 20/40 or better in spite of sufficient anti-VEGF treatment. Thus, incomplete response to anti-VEGF therapy, and specifically PDA and SVR, represent significant clinical unmet needs. In this review, we will explore PDA and SVR in NVAMD, characterizing the clinical manifestations and exploring the pathobiology of each. We will demonstrate that PDA occurs most frequently in NVAMD patients who develop high-flow CNV lesions with arteriolarization, in contrast to patients with capillary CNV who are highly responsive to anti-VEGF therapy. We will review investigations of experimental CNV and demonstrate that both types of CNV can be modeled in mice. We will present and consider a provocative hypothesis: formation of arteriolar CNV occurs via a distinct pathobiology, termed neovascular remodeling (NVR), wherein blood-derived macrophages infiltrate the incipient CNV lesion, recruit bone marrow-derived mesenchymal precursor cells (MPCs) from the circulation, and activate MPCs to become vascular smooth muscle cells (VSMCs) and myofibroblasts, driving the development of high-flow CNV with arteriolarization and perivascular fibrosis. In considering SVR, we will discuss the concept that limited or poor vision in spite of anti-VEGF may not be caused simply by photoreceptor degeneration but instead may be associated with photoreceptor synaptic dysfunction in the neurosensory retina overlying CNV, triggered by infiltrating blood-derived macrophages and mediated by Müller cell activation Finally, for each of PDA and SVR, we will discuss current approaches to disease management and treatment and consider novel avenues for potential future therapies.

The spectrum of polypoidal choroidal vasculopathy in Caucasians: clinical characteristics and proposal of a classification. Graefes Arch Clin Exp Ophthalmol 2020; 259:351-361. [PMID: 32812132 PMCID: PMC7843551 DOI: 10.1007/s00417-020-04844-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Revised: 07/06/2020] [Accepted: 07/10/2020] [Indexed: 12/22/2022] Open
Abstract
Purpose To describe the clinical characteristics and outcome of polypoidal choroidal vasculopathy (PCV), also known as aneurysmal type 1 (sub-retinal pigment epithelium (RPE)) neovascularization, in Caucasian patients. Methods Single-centre study in 66 Caucasian patients with a diagnosis of PCV based on optical coherence tomography scan and indocyanine green angiography. Clinical characteristics and multimodal imaging were collected and assessed by an experienced retina specialist. Results This study involved 74 eyes of 66 patients with PCV, with a mean age at onset of 73 years and a female preponderance of 66%. The mean number of polypoidal lesions per eye was 1 (range: 1–5 lesions), out of which 75% was located in the macula and 19% in the peripapillary region. Of the 74 eyes, 37 eyes (50%) had PCV associated with a drusenoidal neovascular age-related macular degeneration (AMD) phenotype (PCV-AMD) and 18 eyes (24%) had PCV associated with non-polypoidal type 1 choroidal neovascularization/branching vascular network (PCV-BVN) without signs of drusenoidal AMD, while 19 eyes (26%) had idiopathic, isolated PCV (iPCV). The mean subfoveal choroidal thickness measured in 22 patients was 245 μm (range: 71–420 μm). In 51% of patients, the initially performed therapy showed good anatomical recovery (resolution of intra- and subretinal fluid). Conclusions A spectrum of PCV (aneurysmal type 1/sub-RPE neovascularization) can be seen in Caucasian patients. PCV associated with a drusenoidal neovascular AMD phenotype in Caucasians is phenotypically and presumably pathophysiologically more associated with neovascular AMD (PCV-AMD: type A PCV). However, this may not be the case for patients with PCV with non-polypoidal type 1 choroidal neovascularization or BVN and no signs of drusenoidal AMD (PCV-BVN: type B PCV), and for patients with idiopathic PCV without associated drusen or BVN (iPCV; type C PCV). Most patients have a thin choroid, even when drusen are absent. For the entire patient group, a moderate anatomical recovery was observed after treatment.

Polypoidal Choroidal Vasculopathy: Consensus Nomenclature and Non-Indocyanine Green Angiograph Diagnostic Criteria from the Asia-Pacific Ocular Imaging Society PCV Workgroup. Ophthalmology 2020; 128:443-452. [PMID: 32795496 DOI: 10.1016/j.ophtha.2020.08.006] [Citation(s) in RCA: 95] [Impact Index Per Article: 23.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Revised: 08/06/2020] [Accepted: 08/06/2020] [Indexed: 10/23/2022] Open
Abstract
PURPOSE To develop consensus terminology in the setting of polypoidal choroidal vasculopathy (PCV) and to develop and validate a set of diagnostic criteria not requiring indocyanine green angiography (ICGA) for differentiating PCV from typical neovascular age-related macular degeneration (nAMD) based on a combination of OCT and color fundus photography findings. DESIGN Evaluation of diagnostic test results. PARTICIPANTS Panel of retina specialists. METHODS As part of the Asia-Pacific Ocular Imaging Society, an international group of experts surveyed and discussed the published literature regarding the current nomenclature and lesion components for PCV, and proposed an updated consensus nomenclature that reflects our latest understanding based on imaging and histologic reports. The workgroup evaluated a set of diagnostic features based on OCT images and color fundus photographs for PCV that may distinguish it from typical nAMD and assessed the performance of individual and combinations of these non-ICGA features, aiming to propose a new set of diagnostic criteria that does not require the use of ICGA. The final recommendation was validated in 80 eyes from 2 additional cohorts. MAIN OUTCOME MEASURES Consensus nomenclature system for PCV lesion components and non-ICGA-based criteria to differentiate PCV from typical nAMD. RESULTS The workgroup recommended the terms polypoidal lesion and branching neovascular network for the 2 key lesion components in PCV. For the diagnosis of PCV, the combination of 3 OCT-based major criteria (sub-retinal pigment epithelium [RPE] ring-like lesion, en face OCT complex RPE elevation, and sharp-peaked PED) achieved an area under the receiver operating characteristic curve of 0.90. Validation of this new scheme in a separate subset 80 eyes achieved an accuracy of 82%. CONCLUSIONS We propose updated terminology for PCV lesion components that better reflects the nature of these lesions and is based on international consensus. A set of practical diagnostic criteria applied easily to spectral-domain OCT results can be used for diagnosing PCV with high accuracy in clinical settings in which ICGA is not performed routinely.

Abstract
BACKGROUND/AIMS To identify the clinical characteristics of polypoidal choroidal vasculopathy (PCV) in Caucasian patients and assess the prevalence of anti-vascular endothelial growth factor (anti-VEGF) resistance. METHODS This involved a retrospective chart review of Caucasian patients diagnosed with PCV and utilizing indocyanine green angiography with the scanning laser ophthalmoscope. Data collected included patients' demographics, disease characteristics, and treatment response. RESULTS There were 54 eyes of 49 patients with PCV; 51.0% were male and 49.0% were female with a mean age of 72.9 years. Forty-four patients (89.8%) had PCV unilaterally and 10.2% (5 patients) had PCV bilaterally. PCV was located in the macula in 79.6%, in the peripapillary region in 16.7%, and in both regions in 3.7%. PCV commonly presents with serous detachment (66.7%), retinal pigment epithelial detachment (RPED) (51.9%) and subretinal hemorrhage (37.0%). Twenty-nine eyes were included in the treatment response analysis, with 18 eyes (62.1%) showing persistent disease activity after 3 initial injections of anti-VEGF treatment. CONCLUSION PCV in Caucasian patients is more often unilateral and presents more commonly in the macular region than the peripapillary region. Serous detachment and RPED are the 2 most common findings. Resistance to current anti-VEGF treatment was noted frequently; it is thus extremely important to identify this subtype of type I subretinal neovascularization.

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 To evaluate the prevalence of polypoidal choroidal vasculopathy (PCV) in different ethnic populations and to determine the prevalence of PCV in eyes with exudative age-related macular degeneration (AMD) that is sensitive and resistant to anti-vascular endothelial growth factor (VEGF) therapy. DESIGN Retrospective chart review. PARTICIPANTS Two hundred fifty-three eyes of 221 patients with exudative AMD. METHODS Baseline data were collected on all eyes diagnosed with exudative AMD, which included ethnic data. Polypoidal choroidal vasculopathy was diagnosed using indocyanine green angiography (ICGA) with the scanning laser ophthalmoscope. Exudative AMD eyes were separated into 2 groups: anti-VEGF-resistant eyes with persistent subretinal fluid, subretinal hemorrhage, or macular edema after 4 anti-VEGF injections and anti-VEGF-sensitive eyes defined as eyes without residual disease activity. The prevalence of PCV was determined in each group based on ICGA. MAIN OUTCOME MEASURES Prevalence of PCV in exudative AMD, and in different ethnic populations, and prevalence of anti-VEGF resistance in eyes with and without PCV. RESULTS Exudative AMD was diagnosed in 253 eyes of 221 patients. Polypoidal choroidal vasculopathy was noted to have a prevalence of 45.1% (114/253 eyes) in the overall population. Polypoidal choroidal vasculopathy was noted in 51.6% (81/157) of eyes with wet AMD in Asians, 31.9% (23/72 eyes) of eyes with wet AMD in white persons, and 28.6% (4/14 eyes) in a small group of Pacific Islanders. Polypoidal choroidal vasculopathy was diagnosed in 50% (60/120 eyes) of eyes in the anti-VEGF-resistant group, which is more prevalent than the 30.2% (29/96 eyes) in the anti-VEGF-sensitive group (P < 0.001). CONCLUSIONS Polypoidal choroidal vasculopathy is more prevalent in Asian patients with exudative AMD, but is more prevalent than generally recognized in white patients. Polypoidal choroidal vasculopathy is more prevalent in anti-VEGF-resistant eyes in both white and Asian patients, which could help to predict therapeutic response.

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
PURPOSE To investigate the etiologies and characteristics of choroidal neovascularization (CNV) in young Chinese patients. METHODS A retrospective review of young Chinese patients (< 50 years of age) with CNV from January 2010 to June 2016 was performed. RESULTS Of the 501 patients (537 eyes) with CNV, 58.7% were female, and 7.2% had bilateral CNV. The mean age was 35 years. The etiologies were idiopathic CNV (ICNV, 43.9%), pathologic myopia (PM, 21.9%), punctate inner choroidopathy (PIC, 17.4%), polypoidal choroidal vasculopathy (4.4%), multifocal choroiditis with panuveitis (3.6%), and other disorders (8.8%). Five hundred and six CNVs (94.2%) showed a predominantly classic CNV composition on fundus fluorescein angiography (FFA) and 316 CNVs (96.6%) were type 2 CNV on optical coherence tomography (OCT). CONCLUSION The etiologies of CNV in young Chinese patients were diverse, and ICNV, PM, and PIC were the three most common etiologies. Most CNVs were classic on FFA and type 2 on OCT.

Abstract
PURPOSE We aimed to assess the subfoveal choroidal thickness (SFChT) and the effect of treatment with anti-vascular endothelial growth factor (anti-VEGF) agents on the SFChT in age-related macular degeneration (AMD) subtypes. METHODS We enrolled 128 eyes of 107 patients with neovascular AMD (60 women; 47 men; mean age, 73.6 ± 8.9 years), and prospectively evaluated the best-corrected visual acuity (BCVA) and SFChT at baseline and at 3, 6, and 12 months after treatment with anti-VEGF agents. Patients were assigned to the typical AMD, polypoidal choroidal vasculopathy (PCV), and retinal angiomatous proliferation (RAP) subgroups. RESULTS In total, 85 (66.4%), 31 (24.2%), and 12 (9.4%) eyes were assigned to the typical AMD, PCV, and RAP subgroups, respectively. The baseline mean BCVA was 0.75 ± 0.26, 0.72 ± 0.21, and 0.77 ± 0.24 logMAR in the typical AMD, PCV, and RAP subgroups, respectively (p = 0.774). The mean baseline SFChT was 203.20 ± 35.80, 271.80 ± 24.50, and 182.93 ± 31.31 µm, respectively (p < 0.001). Mean SFChT significantly decreased from baseline to 3, 6, and 12 months after treatment. The RAP subtype presented a significantly higher decrease in SFChT compared to the other subtypes (p = 0.01). The percentage reduction in SFChT was not significantly correlated with the number of injections (r = -0.02; p = 0.823). No association was observed between baseline SFChT and final visual acuity at 12 months (r = 0.0; p = 0.586). CONCLUSIONS SFChT was greatest in eyes with PCV and least in eyes with RAP. The reduction in SFChT after treatment was greater in the RAP cases. The decrease in SFChT after 12 months of anti-VEGF treatment was not associated with the number of injections and there was no correlation between the baseline SFChT and visual acuity in all AMD subtypes.

Abstract
Choroidal neovascularization (CNV) is a severe eye disease that leads to blindness, especially in the elderly population. Various endogenous and exogenous regulatory factors promote its pathogenesis. However, the detailed molecular biological mechanisms of CNV have not been fully revealed. In this study, by using advanced computational tools, a number of key gene ontology (GO) terms and KEGG pathways were selected for CNV. A total of 29 validated genes associated with CNV and 17,639 nonvalidated genes were encoded based on the features derived from the GO terms and KEGG pathways by using the enrichment theory. The widely accepted feature selection method-maximum relevance and minimum redundancy (mRMR)-was applied to analyze and rank the features. An extensive literature review for the top 45 ranking features was conducted to confirm their close associations with CNV. Identifying the molecular biological mechanisms of CNV as described by the GO terms and KEGG pathways may contribute to improving the understanding of the pathogenesis of CNV.

A 55-year-old woman presented with a history of decreased vision in her left eye. Fundoscopy, fluorescein and indocyanine green angiography, and optical coherence tomography imaging revealed RAP and PCV lesions in her left eye at first diagnosis. The patient received intravitreal ranibizumab therapy but developed tachyphylaxis after the first dose despite having three monthly doses. Switching to intravitreal aflibercept injection in our case resulted in anatomic and functional improvement.

Abstract
BACKGROUND AND OBJECTIVE To evaluate the diagnostic capability of en face spectral-domain optical coherence tomography (SD-OCT) in patients with polypoidal choroidal vasculopathy (PCV) diagnosed by indocyanine green angiography (ICGA). PATIENTS AND METHODS A retrospective, consecutive case series of 100 eyes diagnosed with PCV by ICGA were imaged with en face SD-OCT. Evaluation of the PCV complex on en face SD-OCT was performed on the ability to diagnose PCV by the characteristic configuration of the PCV complex and the extent and size of the PCV lesion. RESULTS The PCV complex was better visualized on ICGA in 45 eyes, on en face SD-OCT in 44 eyes, and equally well in 11 eyes. The extent of the PCV complex was larger on en face SD-OCT in 65 eyes, larger on ICGA in 23 eyes, and equal in size in 12 eyes. CONCLUSION En face SD-OCT images the characteristic findings of PCV and provides a noninvasive way to diagnose and treat PCV when ICGA is not available.
