Abstract
PURPOSE To describe a patient with venous overload choroidopathy in whom venous bulbosities masqueraded as polyps and intervortex venous anastomosis mimicked a branching vascular network, giving the appearance of polypoidal choroidal vasculopathy. METHODS The patient had complete ophthalmic examination including indocyanine green angiography and optical coherence tomography. Venous bulbosities were defined on indocyanine green angiography as focal dilations in which the diameter of the dilation is two times that of the host vessel. RESULTS A 75-year-old woman presented with combined subretinal and subretinal pigment epithelium hemorrhages in the right eye. During indocyanine green angiography, focal nodular hyperfluorescent lesions connected to a network of vessels were observed, which looked like polyps and branching vascular network in polypoidal choroidal vasculopathy. In both eyes, the midphase angiogram had multifocal choroidal vascular hyperpermeability. There was late-phase placoid staining nasal to the nerve in the right eye. During enhanced depth imaging-optical coherence tomography evaluation, there were no retinal pigment epithelium elevations that would be expected with polyps or branching vascular network in the right eye. A double-layer sign was seen corresponding to the placoid area of staining. Diagnosis of venous overload choroidopathy and choroidal neovascularization membrane was made. She was treated with intravitreal antivascular endothelial growth factor injections for the choroidal neovascularization membrane. CONCLUSION Indocyanine green angiography findings in venous overload choroidopathy may mimic polypoidal choroidal vasculopathy, but differentiation is essential because it has implications for treatment. Similar findings may have been misinterpreted in the past and may have previously contributed to conflicting clinical and histopathologic descriptions of polypoidal choroidal vasculopathy.

Abstract
PURPOSE To evaluate 1-year outcomes of loading phase treatment followed by maintenance therapy using a treat-and-extend (TAE) regimen with intravitreal faricimab for neovascular age-related macular degeneration (nAMD). STUDY DESIGN Retrospective, interventional case series. METHODS We retrospectively studied 40 eyes of 38 consecutive patients with treatment-naïve nAMD, assessing best-corrected visual acuity (BCVA), foveal thickness, central choroidal thickness (CCT), total number of injections over 1 year, and intended injection interval at the last visit. RESULTS Thirty eyes (75.0%) had completed the 1-year intravitreal faricimab treatment. Their BCVA showed significant improvement, with significant reductions in foveal thickness and CCT. The total number of injections during the 1-year treatment period was 6.6 ± 0.7. The intended injection interval at the last visit was 12.7 ± 3.3 weeks. Of the 10 eyes (25.0%) failing to complete the 1-year faricimab treatment, 1 eye developed intraocular inflammation after the loading phase treatment but showed no recurrence of exudative changes, and no further treatment was required. Moreover, 5 eyes switched to intravitreal brolucizumab injection due to persistent exudative changes with an 8-week interval of faricimab injections. The remaining 4 eyes either dropped out or the patient died. CONCLUSIONS A loading phase treatment followed by a TAE regimen with intravitreal faricimab appears to be generally safe and effective for improving visual acuity and ameliorating exudative changes in eyes with nAMD. However, there might be cases in which exudative changes cannot be adequately controlled with injections of faricimab every 8 weeks in the maintenance phase.

Abstract
This retrospective study evaluated the real-world safety and effectiveness of switching to intravitreal brolucizumab for refractory neovascular age-related macular degeneration (nAMD). A total of 81 patients who received brolucizumab injections as switch therapy were followed for more than 3 months. A good response was defined as better anatomical improvement or extended injection intervals compared with previous anti-vascular endothelial growth factor (VEGF) treatment over a mean follow-up period of 41.4 weeks. Approximately 82.7% of patients showed a good response after switching. After 1 year, patients showed significant visual gains (+ 6.6 letters, p = 0.006) and central retinal thickness reductions (- 112.6 µm, p < 0.001), with 30.8% having injection intervals extended over 12 weeks. In the poor-response group, visual acuity and anatomical outcomes worsened soon after switching. More previous injections, thinner baseline central retina, and the presence of prechoroidal cleft or polypoidal lesion resulted in a better response (p < 0.05). Adverse effects occurred in eight eyes (9.9%), including one retinal vascular occlusion and seven intraocular inflammation cases, which were unrelated to the response. Most patients with nAMD refractory to anti-VEGF treatment demonstrated anatomical improvement or extended injection intervals after switching. This study shows that identified structural biomarkers may predict treatment response and select an appropriate therapeutic strategy.

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

One-year results of treat-and-extend regimen with intravitreal brolucizumab for treatment-naïve neovascular age-related macular degeneration with type 1 macular neovascularization. Sci Rep 2022; 12:8195. [PMID: 35581196 PMCID: PMC9114020 DOI: 10.1038/s41598-022-10578-1] [Citation(s) in RCA: 27] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 04/11/2022] [Indexed: 11/09/2022] Open
Abstract
We evaluated 1-year outcomes of loading phase treatment followed by maintenance treatment using a treat-and-extend (TAE) regimen with intravitreal brolucizumab for neovascular age-related macular degeneration (nAMD) associated with type 1 macular neovascularization (MNV). We analyzed 68 eyes of 65 consecutive patients with treatment-naïve nAMD associated with type 1 MNV. Forty-five eyes (66.2%) completed the 1-year treatment with intravitreal brolucizumab. In those cases, best-corrected visual acuity (BCVA) showed significant improvement, while there were significant reductions in foveal thickness and central choroidal thickness, after the initial brolucizumab injection, which were maintained until the last visit. The average total number of injections over 1 year was 6.4 ± 0.6. The average intended injection interval at the last visit was 14.0 ± 2.9 weeks. Moreover, 17of 23 eyes (73.9%) with polypoidal lesions showed complete regression of these lesions after the loading phase treatment. Although intraocular inflammation (IOI) was observed in 15 of 68 eyes (22.1%) within 1 year, amelioration in response to combination therapy with topical and subtenon injection of steroids, without visual decline, was obtained. These results indicate that loading phase treatment followed by the TAE regimen with intravitreal brolucizumab might improve BCVA and ameliorate exudative changes in eyes with treatment-naïve nAMD associated with type 1 MNV. Moreover, intravitreal brolucizumab can potentially reduce the treatment burden of nAMD. Prompt steroid therapy might be efficacious for ameliorating brolucizumab-related IOI without visual decline.

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

Small dome-shaped pigment epithelium detachment in polypoidal choroidal vasculopathy: an under-recognized sign of polypoidal lesions on optical coherence tomography? Eye (Lond) 2022; 36:733-741. [PMID: 33833415 PMCID: PMC8956584 DOI: 10.1038/s41433-020-01390-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 11/27/2020] [Accepted: 12/18/2020] [Indexed: 02/02/2023] Open
Abstract
PURPOSE To evaluate the diagnostic accuracy of spectral-domain optical coherence tomography (SD-OCT) and swept-source optical coherence tomographic angiography (SS-OCTA) to identify polypoidal lesions in serous or serosanguinous maculopathy. MATERIALS AND METHODS A retrospective review of patients presenting pigment epithelial detachments (PEDs) with the diagnosis of polypoidal choroidal vasculopathy (PCV), neovascular age-related macular degeneration (nAMD), and central serous chorioretinopathy (CSC), all of which underwent SD-OCT, SS-OCTA, and indocyanine green angiography (ICGA). Typical features of polypoidal lesions on SD-OCT included sharply peaked PED, notched PED, and hyperreflective ring underneath PED. SS-OCTA feature was vascularized PEDs on cross-sectional images corresponding to cluster-like structures on en face images. The parameters of PEDs were measured for analysis. RESULTS Of 72 eyes, 30 had PCV, 22 had nAMD, and 20 had CSC. A total of 128 localized PEDs were detected on SD-OCT. Typical features on SD-OCT had a high specificity (94.0%) but a limited sensitivity (73.8%). SS-OCTA features provided a higher sensitivity (96.7%). PEDs of the polypoidal lesions unrecognized by SD-OCT were dome-shaped, with smaller ratio of height to base diameter and less area, and almost had heterogeneous internal reflectivity and a connected double-layer sign. Some lesions misidentified by SS-OCTA developed into ICGA-proven polypoidal lesions at follow-up visits. CONCLUSION A small dome-shaped PED with heterogeneous internal reflectivity and a connected double-layer sign on SD-OCT may suggest a polypoidal lesion of PCV. SS-OCTA may be a helpful tool to investigate preclinical PCV and observe the formation of polypoidal lesions.

Abstract
PURPOSE To compare long-term outcomes between typical exudative age-related macular degeneration (TexAMD) and polypoidal choroidal vasculopathy (PCV), and to investigate factors related to the outcomes. METHODS This retrospective study included 319 eyes (164 with TexAMD and 155 with PCV) treated with anti-vascular endothelial growth factor and followed more than 5 years. The primary outcome was visual acuity (VA) change from baseline to final visit. Linear regression analyses were used to determine factors associated with final VA. RESULTS Baseline logMAR VA was 0.7 ± 0.5 in the TexAMD group and 0.5 ± 0.4 in the PCV group (p < 0.001). After a mean follow-up of 9 years, final VA was also significantly worse in the TexAMD group than in the PCV group (0.9 ± 0.6 vs. 0.6 ± 0.5; p < 0.001). The PCV group showed longer maintenance of improved vision and later onset of significant visual decline than the TexAMD group. In multivariate analysis, loss to follow-up, worse baseline VA, macular atrophy, and subretinal fibrosis were significantly associated with poor final VA in both groups. CONCLUSION PCV eyes showed relatively favorable long-term visual outcome than TexAMD eyes. The results of this study emphasized the importance of compliance with treatment, along with other well-known prognostic factors.

Short-term outcomes of intravitreal brolucizumab for treatment-naïve neovascular age-related macular degeneration with type 1 choroidal neovascularization including polypoidal choroidal vasculopathy. Sci Rep 2021; 11:6759.

Abstract
We evaluated the efficacy and safety of loading phase treatment with intravitreal brolucizumab for neovascular age-related macular degeneration (nAMD) with type 1 choroidal neovascularization (CNV). We analyzed consecutive 42 eyes of 40 patients with treatment-naïve nAMD associated with type 1 CNV. Three monthly injections of brolucizumab were completed in 36 eyes (85.7%). In those cases, best-corrected visual acuity (BCVA) was 0.24 ± 0.27 at baseline and improved significantly to 0.12 ± 0.23 after 3 months (P < 0.001). Central macular thickness was 301 ± 110 µm at baseline and decreased significantly to 160 ± 49 µm after 3 months (P < 0.001). Dry macula was achieved in 34 eyes (94.4%) after the loading phase. Central choroidal thickness was 264 ± 89 µm at baseline and decreased significantly to 223 ± 81 µm after 3 months (P < 0.001). Indocyanine green angiography after the loading phase revealed complete regression of polypoidal lesions in 15 of the 19 eyes (78.9%) with polypoidal lesions. Non-infectious intraocular inflammation (IOI) was observed in 8 of 42 eyes (19.0%) during the loading phase, while showing amelioration in response to combination therapy with topical and subtenon injection of steroids. In these eyes, BCVA after 3 months had not deteriorated as compared to that at baseline. These results indicate that loading phase treatment with intravitreal brolucizumab might be effective for improving visual acuity and reducing exudative changes in eyes with nAMD associated with type 1 CNV. Moreover, polypoidal lesions appear to frequently regress after this treatment. However, we must monitor patients carefully for brolucizumab-related IOI, and administer steroid therapy promptly.

Quantitative measures of vortex veins in the posterior pole in eyes with pachychoroid spectrum diseases. Sci Rep 2020; 10:19505. [PMID: 33177540 PMCID: PMC7658995 DOI: 10.1038/s41598-020-75789-w] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Accepted: 10/14/2020] [Indexed: 11/16/2022] Open
Abstract
Pachychoroid spectrum diseases have attracted increasing attention, though their pathophysiology has yet to be fully elucidated. In this study, we assessed the vascular diameters of vortex veins in pachychoroid spectrum diseases such as central serous chorioretinopathy (CSC), pachychoroid neovasculopathy without polypoidal lesions (PNV), and pachychoroid neovasculopathy with polypoidal lesions (polypoidal choroidal vasculopathy: PCV). In a retrospective case series of 94 eyes with CSC, 60 eyes with PNV and 57 with PCV, we binarized en face optical coherence tomography (OCT) images of choroidal vortex veins and analyzed the mean diameter of vortex veins. The presence of anastomosis between the superior and inferior vortex veins and central choroidal thickness (CCT) were also evaluated using OCT images. CSC showed significantly larger mean diameter of vortex veins than PCV (P < 0.05). Anastomosis between superior and inferior vortex veins was observed in over 90% of eyes with each pachychoroid spectrum disease. The patients with CSC were the youngest, followed by PNV patients, and then patients with PCV. The largest CCT values were observed in CSC eyes, followed by PNV eyes, and then PCV eyes. CCT correlated with the mean diameter of vortex veins (rs = 0.51, P < 0.01). These findings suggest that congestion of vortex veins might show gradual amelioration corresponding to the development of anastomosis between the superior and inferior vortex veins during the course of progression of pachychoroid spectrum diseases. Moreover, the mean diameter of vortex veins can be used as a parameter indicating choroidal congestion.

Abstract
PURPOSE To evaluate the vascular changes in vortex veins at the posterior pole in pachychoroid spectrum diseases, including central serous chorioretinopathy (CSC), pachychoroid neovasculopathy without polypoidal lesions (PNV), and pachychoroid neovasculopathy with polypoidal lesions (polypoidal choroidal vasculopathy [PCV]). DESIGN Retrospective case-control study. PARTICIPANTS Ninety-two eyes of 89 patients with CSC, 61 eyes of 59 patients with PNV, 63 eyes of 61 patients with PCV, and 25 healthy control eyes of 25 age- and gender-matched participants for each pachychoroid spectrum disease. METHODS Clinical records of patients with pachychoroid spectrum diseases and healthy controls were reviewed. Multimodal images of each group were analyzed. Swept-source OCT was performed to obtain B-mode and en face images in patients with pachychoroid spectrum diseases and healthy controls. All patients underwent fluorescein angiography, indocyanine green angiography, and OCT. MAIN OUTCOME MEASURES Vortex vein anastomosis at the watershed, determined using en face OCT, and central choroidal thickness (CCT), measured using B-mode OCT, were examined in patients and healthy controls. Patient ages also were taken into consideration. RESULTS Patients with CSC were the youngest, followed by patients with PNV, and then those with PCV (P < 0.01, CSC vs. PNV and PNV vs. PCV), whereas CSC eyes showed the highest CCT values, followed by the PNV and then the PCV eyes (P < 0.01, CSC vs. PNV; P < 0.05, PNV vs. PCV). Central choroidal thickness was significantly greater in pachychoroid spectrum diseases than in healthy controls. No significant CCT differences were found among healthy controls. Anastomosis between superior and inferior vortex veins was observed in more than 90% of eyes with pachychoroid spectrum diseases, making this finding significantly more frequent than in healthy controls (P < 0.01, each pachychoroid spectrum disease vs. control). Polypoidal choroidal vasculopathy showed a significantly higher rate of anastomosis than CSC (P < 0.05). CONCLUSIONS Anastomosis between superior and inferior vortex veins was found to be a common feature in pachychoroid spectrum diseases. Longstanding vortex vein congestion may lead to the development of pachychoroid spectrum diseases. Choroidal congestion may be compensated for by new drainage routes formed via vortex vein anastomosis.

Abstract
BACKGROUND/OBJECTIVES To compare the detailed optical coherence tomography (OCT)-based morphological parameters of pigment epithelial detachment (PED) in eyes presenting with neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV), and to assess whether these PED-associated parameters influence 1-year visual outcomes. SUBJECT/METHODS We analysed images from a prospective observational study of treatment-naive Asian participants with nAMD or PCV. An independent reading centre graded baseline morphological features of PED on spectral-domain OCT, including greatest height, greatest width, greatest volume, morphology (predominantly dome shaped versus peaked), presence of retinal pigment epithelium (RPE) tear and cholesterol bands. The influence of these baseline features on 12 months best corrected visual acuity (BCVA) was evaluated. RESULTS Seventy-eight eyes of 78 participants with PED were studied. In total, 40 (51.3%) participants had nAMD and 38 (48.7%) had PCV. Eyes with PCV, compared with nAMD, had PED of greater height (455.9 µm versus 389.9 µm; P = 0.035) and had higher prevalence of RPE tear (22.9 versus 5.3%; P = 0.041). In the multivariate analysis, only baseline BCVA was significantly associated with month 12 BCVA, but none of the PED-associated OCT parameters at baseline influenced month 12 BCVA. CONCLUSIONS Despite the differences in PED height and prevalence of RPE tear between nAMD and PCV, none of these PED morphological factors on OCT at baseline significantly influenced visual outcome at 12 months.

Abstract
Polypoidal choroidal vasculopathy as a disease is yet to be comprehended completely. The clinical features consisting of huge serosanguineous retinal pigment epithelial and neurosensory layer detachments, although unique may closely mimick neovascular age-related macular degeneration and other counterparts. The investigative modalities starting from indocyanine angiography to optical coherence tomography angiography provide diagnostic challenges. The management strategies based on the available therapies are plenty and not vivid. A detailed review with clarifying images has been compiled with an aim to help the readers in getting a better understanding of the disease.

Abstract
Purpose of review The aim of this review is to summarize developments in the treatment of active polypoidal choroidal vasculopathy (PCV). PCV is associated with a poor visual prognosis as a consequence the condition's hallmark polypoidal dilatation and a branching network resulting in recurrent hemorrhages and serous leakage. Recent findings Recent research has provided new insights into the pathogenesis of PCV. While still considered a subtype of age-related macular degeneration, suggestions that PCV belongs to a spectrum of conditions that present with a pachychoroid are increasingly well accepted. Treatment remains challenging. Combination therapy (photodynamic therapy (PDT) and intravitreal anti-vascular endothelial growth factor (VEGF)) is associated with higher polyp closure rate, but polyp closure rate has not been correlated with superior visual outcomes. Current data points to non-inferiority of anti-VEGF alone versus combined with PDT when final vision acuity is the study outcome. Summary PCV remains a clinical challenge. Classification and treatment of the condition continues to evolve. Combination therapy may not be superior to anti-VEGF treatment alone in terms of visual acuity outcome, however data on long-term recurrence should be compared in formulating preferred treatment plans.

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
The term aneurysmal type 1 neovascularization is derived from terminology, which is established in the literature but has fallen out of use. We believe that aneurysmal type 1 neovascularization accurately describes the lesions which define the entity known as polypoidal choroidal vasculopathy (PCV). Over the last three decades, the clinical spectrum of PCV has expanded to recognize the occurrence of the aneurysmal (polypoidal) lesions in different contexts, resulting in a complex and unwieldy taxonomy based sometimes on circumstantial findings rather than mechanistic considerations. Advances in multimodal imaging provides increasingly convincing evidence that the lesions which define various forms of PCV are indeed vascular and arise from type 1 neovascular networks. The understanding of PCV as type 1 neovascularization with aneurysms renews focus on the question as to why some patients with type 1 neovascularization develop aneurysms while others do not. Conceptual themes and potential for further study are discussed.

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.

Abstract
PURPOSE To determine if changes in pigment epithelial detachment (PED) area and volume predict retreatment in polypoidal choroidal vasculopathy (PCV). DESIGN Retrospective case-control study. METHODS PCV patients on pro re nata (PRN) anti-vascular endothelial growth factor (VEGF) therapy with >1 year follow-up at an academic retina service were included. Monthly anti-VEGF injections were given until a dry macula was achieved, and treatment deferred. Retreatment indication was recurrence of intraretinal or subretinal fluid or new hemorrhage. PED area and volume changes between visits with a dry macula ("D") and immediate preceding visits ("D-1") were analyzed with an automated optical coherence tomography-based software. Univariate and multivariate analyses were conducted to determine associations between changes in PED parameters and retreatment need at immediate subsequent visits ("D+1"). RESULTS Twenty-two PCV patients (mean age 69.6 years) were included. Of 46 visits D, 11 (23.9%) were followed by retreatment at D+1. An increase in PED area (>0.43 mm2) and volume (>0.0245 mm3) from D-1 to D was associated with 18.2 (95% CI, 3.7-125.6; P < .001) and 101.9 (95% CI, 9.5-14 308.0; P < .001) higher retreatment odds at D+1, respectively. These associations remained significant after multivariate analyses adjusting for baseline PED area or volume, greatest linear dimension, and type of anti-VEGF agent. CONCLUSION In PCV on PRN anti-VEGF therapy, increases in PED area and volume at one visit, despite achievement of a dry macula, are associated with retreatment at the next visit. Retreatment criteria relying on intraretinal or subretinal fluid or new hemorrhages may be expanded to include PED changes. Studies are needed to determine if using PED parameters in treatment decisions reduces recurrences.

Abstract
PURPOSE To investigate the sensitivity and specificity of spectral domain optical coherence tomography in distinguishing polypoidal choroidal vasculopathy (PCV) from typical neovascular age-related macular degeneration (nAMD). METHODS One hundred and eighty-eight eyes in 156 patients with active PCV or typical nAMD were enrolled prospectively. Three spectral domain optical coherence tomography manifestations, pigment epithelium detachment, double-layer sign, and thumb-like polyps were estimated in all the eyes. A diagnostic test to differentiate PCV from nAMD based on spectral domain optical coherence tomography was performed. Furthermore, the sensitivity and specificity was validated in a retrospective series of patients. RESULTS Pigment epithelium detachment, double-layer sign, and thumb-like polyps were more common in PCV eyes than in nAMD eyes. When the cutoff point was set as at least 2 positive signs out of 3 in the diagnostic test, the sensitivity was 89.4% and specificity was 85.3%. The results of the validation test further confirmed the strategy, with satisfying sensitivity (87.5%) and specificity (86.2%). CONCLUSION Spectral domain optical coherence tomography is sensitive and specific in distinguishing PCV from nAMD. From these results, the presence of at least two out three signs (pigment epithelium detachment, double-layer sign, and thumb-like polyps) indicates a positive test and is therefore suggested to be the screening strategy for PCV.

Abstract
Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in elderly people globally. It is estimated that there will be more Asians with AMD than the rest of the world combined by 2050. In Asian populations, polypoidal choroidal vasculopathy (PCV) is a common subtype of exudative AMD, while choroidal neovascularization secondary to AMD (CNV-AMD) is the typical subtype in Western populations. The two subtypes share many common clinical features and risk factors, but also have different epidemiological and clinical characteristics, natural history and treatment outcomes that point to distinct pathophysiological processes. Recent research in the fields of genetics, proteomics and imaging has provided further clarification of differences between PCV and CNV-AMD. Importantly, these differences have manifested as disparity in response to intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) treatment between PCV and CNV-AMD, emphasizing the need for accurate diagnosis of PCV and in distinguishing PCV from CNV-AMD, particularly in Asian patients. Current clinical trials of intravitreal anti-VEGF therapy and photodynamic therapy will provide clearer perspectives of evidence-based management of PCV and may lead to paradigm shifts in therapeutic strategies away from those currently employed in the treatment of CNV-AMD. Further research is needed to clarify the relative contribution of specific pathways in inflammation, complement activation, extracellular matrix dysregulation, lipid metabolism and angiogenesis to the pathogenesis of PCV. Findings from this research, together with improved diagnostic technology and new therapeutics, will facilitate more optimal management of Asian AMD.

Abstract
OBJECTIVE To establish the diagnostic criteria for polypoidal choroidal vasculopathy (PCV) based on spectral-domain optical coherence tomography (SD OCT) by evaluating the sensitivity and specificity of SD OCT in differentiating PCV from wet age-related macular degeneration (wAMD). METHODS The clinical data were reviewed for 62 patients (63 eyes) with the initial diagnosis of PCV or wAMD between August, 2012 and June, 2016. Twenty-four patients (25 eyes) were diagnosed to have PCV and 38 (38 eyes) had wAMD based on findings by fundus photography, fluorescein angiography (FFA) and indocyanine green angiography (ICGA). Among the 6 features of SD OCT, namely a sharp RPED peak, double-layer sign, multiple RPED, an RPED notch, a hyporeflective lumen representing polyps, and hyperreflective intraretinal hard exudates, findings of the first two features and at least one of the other features sufficed the diagnosis of PCV; in the absence of the first two features, the diagnosis of PCV was also made when at least 3 of the other features were present simultaneously. The sensitivity and specificity of SD OCT-based diagnosis were estimated by comparison with the gold standard ICGA-based diagnosis. RESULTS In the 25 eyes with an established diagnosis of PCV, 23 eyes (92.0%) met the diagnostic criteria based on SD OCT findings; in the 38 eyes with the diagnosis of wAMD, only 4 eyes (10.5%) met the criteria. The sensitivity and specificity of SD OCT-based diagnosis of PCV was 92.0% and 89.5%, respectively. CONCLUSION s We established the diagnostic criteria for PCV based on SD OCT findings with a high sensitivity and specificity. SD OCT shows a strong capacity for differentiating PCV from wAMD.

Abstract
OBJECTIVE To examine patients with polypoidal choroidal vasculopathy (PCV), using spectral-domain optical coherence tomography (SD-OCT) to characterise and locate the PCV lesions. PATIENTS AND METHODS A series of 15 eyes of 10 patients diagnosed with PCV were examined. All eyes were imaged with macular SD-OCT. RESULTS SD-OCT cross-sectional scan findings included atypical and typical pigment epithelial detachments (PEDs). Polyps and neovascularisation were located above Bruch membrane. All 15 eyes (100%) showed sub-retinal fluid (SRF) in association with PEDs. CONCLUSION These SD-OCT findings located the vascular lesions of PCV in the sub-retinal pigment epithelium (RPE) space, and strongly suggest that PCV is a variant of type 1 neovascularization.

Abstract
Age related macular degeneration (AMD) in Asians has been suggested to differ from their Western counterparts in terms of epidemiology, pathogenesis, clinical presentation and treatment. In particular, polypoidal choroidal vasculopathy (PCV) appears to be the predominant subtype of exudative AMD in Asian populations, in contrast to choroidal neovascularization secondary to AMD (CNV-AMD) in Western populations. Epidemiological data on PCV has been largely limited to hospital-based studies and there are currently no data on the incidence of PCV. Similarities and differences in risk factor profile between PCV and CNV-AMD point to some shared pathogenic mechanisms but also differential underlying mechanisms leading to the development of each phenotype. Serum biomarkers such as CRP, homocysteine and matrix metalloproteinases suggest underlying inflammation, atherosclerosis and deranged extracellular matrix metabolism as possible pathogenic mechanisms. In addition, recent advances in genome sequencing have revealed differences in genetic determinants of each subtype. While the standard of care for CNV-AMD is anti-vascular endothelial growth factor (VEGF) therapy, photodynamic therapy (PDT) has been the mainstay of treatment for PCV, although long-term visual prognosis remains unsatisfactory. The optimal treatment for PCV requires further clarification, particularly with different types of anti-VEGF agents and possible benefits of reduced fluence PDT.

Abstract
PURPOSE To evaluate the efficacy of spectral-domain optical coherence tomography (SD OCT) compared to indocyanine green angiography (ICGA) in detecting idiopathic polypoidal choroidal vasculopathy (PCV) and in differentiating between PCV and occult choroidal neovascularization (CNV). DESIGN Retrospective observational case-control study. METHODS SD OCTs of 51 eyes of 44 consecutive patients who presented with 1 or more pigment epithelial detachments (PEDs) attributable to either PCV or occult CNV were retrospectively reviewed by a grader masked to the final diagnosis. A qualitative analysis based on the following tomographic findings was performed: sharp PED peak, PED notch, hyporeflective lumen within hyperreflective lesions adherent to retinal pigment epithelium. The diagnosis based on SD OCT alone was compared with the final diagnosis made using ICGA and fluorescein angiography. Sensitivity and specificity were calculated. Patients with classic CNV and central serous chorioretinopathy were excluded. RESULTS Among 51 eyes of 44 patients, 37 had an ICGA-confirmed diagnosis of PCV and 14 had occult CNV. SD OCT based on the features above detected 35 of 37 true-positive PCV lesions but missed 2 ICGA-confirmed lesions (false negatives). SD OCT correctly excluded 13 of 14 non-PCV lesions but misidentified 1 PCV lesion (false positive). These data showed a sensitivity of 94.6% and a specificity of 92.9% for the above SD OCT features in identifying PCV lesions. CONCLUSIONS SD OCT based on the features above allowed for good detection of PCV and differentiation between PCV and occult CNV in this selected clinic population. A careful qualitative analysis of the tomographic findings in patients presenting with PEDs may allow ophthalmologists to distinguish between PCV and occult CNV, decreasing the need for ICGA and the risks related to this procedure.

Abstract
PURPOSE To report spectral-domain optical coherence tomography (SD-OCT) findings in polypoidal choroidal vasculopathy (PCV). PATIENTS AND METHODS Seventeen eyes of 15 consecutive patients diagnosed with PCV based on typical clinical and angiographic findings were imaged with macular SD-OCT including line scans passing through the polyps. RESULTS SD-OCT findings included typical and atypical retinal pigment epithelial (RPE) detachments and subretinal and intraretinal fluid in all eyes. In the areas corresponding to the polypoidal lesions, well-delineated round-oval, sub-RPE cavities were present and were adherent to the posterior surface of the detached RPE above Bruch membrane. No retinal or choroidal connections to the cavities were noted. CONCLUSION These SD-OCT findings document that the vascular lesions in PCV are not located in the inner choroid, but in the sub-RPE space, suggesting that PCV is a variant of type 1 choroidal neovascularization rather than a distinct clinical entity as initially thought.

Abstract
BACKGROUND/AIMS To evaluate changes in fundus autofluorescence (FAF) after treatments for polypoidal choroidal vasculopathy (PCV). METHODS Thirty-six eyes of 35 patients with treatment-naive PCV underwent intravitreal injection of ranibizumab, photodynamic therapy, or a combination of both treatments. FAF and indocyanine green angiography (ICGA) at baseline were compared with those obtained 12 months later about the changes at the affected lesion. RESULTS In the 36 eyes, 88 polyps were detected on ICGA at baseline, and 65 (73.9%) of those showed centred hypoautofluorescence and a circumferential hyperautofluorescent ring on FAF. Twelve months later, ICGA revealed resolution of 42 of those 65 polyps. Of those 42 resolved polyps, 30 hyperautofluorescent rings (71.4%) were eliminated concurrently with the resolution of polyp. Statistical analysis revealed that an elimination of the hyperautofluorescent ring was more frequently observed in association with the resolved polyps than with the persistent polyps (p<0.0001). All the hypoautofluorescent findings corresponding to branching vascular networks at baseline were unchanged during the follow-up period. CONCLUSIONS Elimination of the hyperautofluorescent ring is highly associated with the resolution of the polyp on ICGA. We propose that FAF has a potential as a non-invasive method of evaluating the therapeutic efficacy of treatments for PCV.

Abstract
PURPOSE To evaluate the validity of the novel and noninvasive retro-mode imaging modality of confocal scanning laser ophthalmoscopy (cSLO) for detecting the morphological features of polypoidal choroidal vasculopathy (PCV). DESIGN Prospective, observational, consecutive case series. METHODS Twenty-six patients (29 eyes) with PCV were enrolled in this study. All patients underwent comprehensive ophthalmologic examinations and imaging studies, including retro-mode imaging, fundus autofluorescence (FAF), fundus photography, fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and spectral-domain optical coherence tomography (SD-OCT). We investigated the retro-mode images and compared the results with those of SD-OCT, FFA and ICGA. RESULTS In the 29 PCV eyes, the retro-mode images clearly revealed polypoidal lesions in 27 (93.1%) eyes as well as branching vascular networks in 16 (55.2%) eyes. Others findings, including pigment epithelial detachment (PED) in 20 (69.0%) eyes, neuroretinal detachment (NRD) in 3 (10.3%) eyes, cystoid macular edema (CME) in 3 (10.3%) eyes, drusen in 4 (13.8%) eyes and minute granular changes of the retinal pigment epithelium (RPE) in 12 (41.3%) eyes, were also clearly visualized. When we compared the results with those of SD-OCT, FFA and ICGA, there was no significant difference between ICGA and retro-mode imaging for finding polypoidal lesions and (or) branching choroidal vascular networks (P>0.05). However, the rate of PED detection was significantly better with retro-mode imaging than with the ICGA (P<0.05). The differences were not statistically significant between SD-OCT and retro-mode imaging for detecting PED, NRD, CME, drusen and minute granular RPE changes (P>0.05). The differences were not statistically significant between FFA and retro-mode imaging for detecting PED, NRD, CME (P>0.05). CONCLUSIONS The novel and noninvasive retro-mode imaging by cSLO is able to clearly visualize the morphological features of PCV.

Abstract
PURPOSE To investigate choroidal vascular abnormalities in peripheral exudative hemorrhagic chorioretinopathy, using dynamic ultrawide-field fluorescein angiography (FA) and indocyanine green angiography (ICGA). DESIGN Prospective observational case series. METHODS This institutional study comprised a consecutive series of 40 patients (48 eyes) with peripheral exudative hemorrhagic chorioretinopathy. Choroidal vascular abnormalities were assessed with dynamic ultrawide-field (150-degree) FA and ICGA, using the Staurenghi 230 SLO Retina Lens and the Heidelberg scanning laser ophthalmoscope. The main outcome measures were morphologic descriptions of structural vascular abnormalities and choroidal hemodynamics (comparison with 30 normal eyes). RESULTS The peripheral mass lesions were highly exudative and hemorrhagic, and usually associated with a pigment epithelium detachment. FA revealed nonspecific alterations corresponding to the visible fundoscopic changes (window defects, blockage, staining), but no neovascular membrane. However, despite frequent masking, ICGA showed hyperfluorescent polyp-like structures in the choroid of the lesion area in 33 eyes (69%) and an abnormal choroidal vascular network in 24 eyes (50%). The abnormal choroidal vascular network filled in the arterial or early venous phase, while the polyp-like structures filled some seconds later. Optical coherence tomography revealed the typical dome-shaped elevation of the pigment epithelium over the vascular polyps. Peripheral choriocapillaris closure was observed as well as dilated shunting vessels. CONCLUSION Peripheral exudative hemorrhagic chorioretinopathy shares many characteristics (polyp-like choroidal telangiectases, abnormal choroidal vascular networks, exudative and hemorrhagic presentation) with polypoidal choroidal vasculopathy. Clarification of the precise role of these abnormalities requires further studies.

Abstract
More than a quarter century has passed since the original description of polypoidal choroidal vasculopathy (PCV) in 1982 as a peculiar hemorrhagic disorder involving the macula characterized by recurrent subretinal pigment epithelial bleeding. In the ensuing years, numerous reports have described the expanded clinical spectrum of this entity. PCV is the principal vascular composition of patients of pigmented races experiencing neovascular maculopathies, particularly African Americans and Asians. This form of neovascularization is now known to occur in white patients with or without concomitant drusen, and the site of involvement has extended from the peripapillary area to the peripheral fundus. Indocyanine green angiography has made detection of these abnormal vascular changes more reliable and definitive. More precise diagnosis has also led to a better understanding of specific clinical features that distinguish PCV from more typical proliferations of abnormal choroidal vessels. We review the nature of PCV, including its genetic basis, demographic features, histopathology, clinical manifestations, natural course, response to treatments, and the histopathological and genetic bases. We emphasize multimodal ophthalmic imaging of these vessels, in particular fluorescein and indocyanine green angiography and optical coherence tomography.

Abstract
Five eyes of five patients with polypoidal choroidal vasculopathy (PCV) without acute hemorrhagic changes or subretinal proliferative tissue to observe the three-dimensional structures and to demonstrate the nature of these images and their interpretation. The abnormal networks surrounding polypoidal lesions were considered to be abnormal pathological blood vessels. The segmentation analysis of spectral-domain optical coherence tomography (OCT) has revealed the three-dimensional features of polypoidal lesions and surrounding abnormal blood vessel networks beneath retinal pigment epithelium. The changes of pathological findings of PCV were also detected, including the enlargement of hemorrhagic pigment epithelium detachment (PED). The segmentation analysis is useful to observe PCV lesions from the bird's eye view.

Abstract
PURPOSE To classify polypoidal choroidal vasculopathy (PCV) presenting with both extramacular and macular lesions according to location and clinical manifestations. METHODS We performed a retrospective analysis of 29 eyes presenting with both extramacular and macular PCV lesions by indocyanine green angiography. The patients were classified according to the location of the extramacular lesions and clinical manifestations. RESULTS PCV locations were identified as peripapillary (32.1%), superior (10.7%) or inferior (17.9%) to the optic disc, superior (14.3%) or inferior (7.1%) temporal arcade, temporal to the macula (10.7%), and nasal to the optic disc (7.1%). Clinical manifestations were identified as polyp (10.7%), branching vascular networks (42.9%), pigment epithelial detachment (PED) (17.9%), polyp and branching vascular networks (7.1%), polyp and PED (14.3%), and all three (7.1%). CONCLUSIONS PCV showed extramacular lesions with various clinical manifestations discontinuous from the macular lesions.

Abstract
PURPOSE To evaluate the differences in the optical coherence tomographically determined macular morphology in eyes with polypoidal choroidal vasculopathy (PCV) from eyes with exudative age-related macular degeneration (AMD) quantitatively. METHODS The medical records of 208 eyes of 203 Japanese patients with PCV or exudative AMD who were newly treated for choroidal neovascularization were reviewed. The six linear, low-resolution, high-speed scans of 6 mm were analyzed using a manually assisted computer algorithm, which allowed us to manually draw spline lines arbitrarily on the images so that the subretinal fluid and neurosensory retina could be segmented. The thickness of the neurosensory retina and height of the serous retinal detachment (SRD) within the central 3-mm and 6-mm areas were calculated. RESULTS SRDs were observed in 53% (63/119) of the eyes with exudative AMD and in 78% (69/89) of the eyes with PCV (P < 0.001). The height of the SRD was 21.9 +/- 3.7 microm (+/-SEMs) in eyes with exudative AMD and 56.3 +/- 7.4 microm in eyes with PCV (P < 0.001). The thickness of the neurosensory retina was 300.0 +/- 5.2 microm in eyes with exudative AMD and 275.8 +/- 4.7 microm in eyes with PCV (P < 0.001). CONCLUSION Eyes with PCV are characterized by a higher incidence of SRDs, greater SRD height, and less intraretinal edema than eyes with exudative AMD.

Abstract
BACKGROUND AND OBJECTIVE To compare macular thicknesses in healthy subjects measured with spectral domain optical coherence tomography (SD-OCT) (Cirrus; Carl Zeiss Meditec, Inc., Dublin, CA) with measurements using time domain (TD-OCT) (Stratus; Carl Zeiss Meditec, Inc.). PATIENTS AND METHODS Macular thickness was measured five times in the same eye of 10 healthy subjects with both Cirrus and Stratus to assess reliability and then once in the same eye of 50 healthy subjects with both Cirrus and Stratus to compare the average obtained by each device. RESULTS Using TD-OCT, the coefficient of variations (CV) of the macular thicknesses within a 1-mm central area ranged from 0.7% to 3.3% (mean, 1.33%); with SD-OCT, the range was 0.2% to 1.3% (mean, 0.66%). The mean CV with SD-OCT was significantly smaller than with TD-OCT (P < .05). The average macular thicknesses with TD-OCT and SD-OCT were 197.2 +/- 17.8 microm and 257.6 +/- 19.6 microm, respectively. However, the correlation was significant (correlation coefficient, 0.916, P<.001). CONCLUSION Cirrus showed better reliability than Stratus. Using SD-OCT, the macula was 60-microm thicker than when measured with TD-OCT. Attention should be given to comparing data obtained using different OCT machines.
