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

Abstract
PURPOSE To evaluate the long-term prognosis of polypoidal choroidal vasculopathy (PCV) treated with anti-vascular endothelial growth factor (anti-VEGF) combined with verteporfin photodynamic therapy (PDT), according to polypoidal lesion regression. METHODS This study retrospectively reviewed the data of 33 naïve eyes with PCV treated with anti-VEGF combined with verteporfin PDT and followed-up for at least 7 years. The collected data included demographic profile, best-corrected visual acuity (BCVA), central foveal thickness (CFT), PED volume, and presence of submacular hemorrhage. Regression of polypoidal lesion was determined using indocyanine green angiography and optical coherence tomography. All eyes were divided into regression or persistent groups, based on the polypoidal lesion regression one year after the initial combined treatment. RESULTS BCVA improvement was maintained for 3 years in the regression (p = 0.001) and 1 year in the persistent (p = 0.006) groups, respectively. The mean BCVA of the regression group was better than that of the persistent group over 7 years, but the difference was significant only at 1 year (p = 0.037). The number of eyes which maintained BCVA less than or equal to 0.3 logMAR at 7 years was 11 eyes (64.7%) in regression group and 4 eyes (25.0%) in persistent group (p = 0.022). CONCLUSIONS Regression of the polypoidal lesion at 1 year after the initial combination treatment was associated with favorable long-term visual prognosis, particularly in terms of maintaining good visual acuity.

Abstract
BACKGROUND With the clinical advances in the field of gene therapy, the development of objective measures of visual function of patients with inherited retinal dystrophies (IRDs) is of utmost importance. Here, we propose one such measure. METHODS We retrospectively analyzed data from a cohort of 194 eyes of 97 genetically diagnosed patients with retinitis pigmentosa (RP), the most common IRD, followed at the UPMC Vision Institute. The analyzed data included the reflectivity ratio (RR) of the retinal nerve fiber layer (RNFL) to that of the entire retina, visual acuity (VA) and the thickness of the retinal outer nuclear layer (ONL) and the RNFL. RESULTS There was a strong positive correlation between the RR and VA. Both VA and the RR were negatively correlated with disease duration; VA, but not the RR, was negatively correlated with age. The RR correlated with the ONL but not with the RNFL thickness or the intraocular pressure. Age, RR, disease duration and ONL thickness were found to be independent predictors of VA by multivariate analysis. CONCLUSION The OCT RR could serve as an independent predictor of visual acuity, and by extension of retinal function, in genetically diagnosed RP patients. Such objective measures can be of great value in patient selection for therapeutic trials.

Abstract
Polypoidal choroidal vasculopathy (PCV) is a subtype of neovascular AMD (nAMD) that accounts for a significant proportion of nAMD cases worldwide, and particularly in Asia. Contemporary PCV treatment strategies have closely followed those used in typical nAMD, though there are significant gaps in knowledge on PCV management and it remains unclear if these strategies are appropriate. Current clinical trial data suggest intravitreal anti-vascular endothelial growth factor (VEGF) therapy alone or in combination with photodynamic therapy is effective in managing haemorrhage and exudation in PCV, although the optimal treatment interval, including as-needed and treat-and-extend approaches, is unclear. Newer imaging modalities, including OCT angiography and high-resolution spectral domain OCT have enabled characterisation of unique PCV biomarkers that may provide guidance on how and when treatment and re-treatment should be initiated. Treatment burden for PCV is a major focus of future therapeutic research and several newly developed anti-VEGF agents, including brolucizumab, faricimab, and new modes of drug delivery like the port delivery system, offer hope for dramatically reduced treatment burden for PCV patients. Beyond anti-VEGF therapy, recent developments in our understanding of PCV pathophysiology, in particular the role of choroidal anatomy and lipid mediators in PCV pathogenesis, offer new treatment avenues that may become clinically relevant in the future. This article explores the current management of PCV and more recent approaches to PCV treatment based on an improved understanding of this unique disease process.

Association Between the Degree of Inclusion of Components Identified on Fluorescein or Indocyanine Green Angiography in Target Spots and Relapse of Exudate in Eyes with Polypoidal Choroidal Vasculopathy and Typical Age-Related Macular Degeneration After Photodynamic Therapy. Clin Ophthalmol 2021; 15:2063-2075.

Abstract
Purpose To investigate the association between the inclusion of components identified on images in target spots of photodynamic therapy (PDT) and exudate relapse in eyes with age-related macular degeneration (AMD). Methods Forty-one eyes (39 patients) with polypoidal choroidal vasculopathy (PCV) and 32 eyes (31 patients) with typical AMD (tAMD) who underwent PDT were retrospectively investigated. Each component identified on fluorescein (FA) or indocyanine angiography (IA), optical coherence tomography (OCT), or color photography was graded as not depicted, covered with a margin ≥500 µm or <500 µm, and protruding. Associations between these grades and the dry rate (proportion of subjects with continuous absence of exudate over following 12-month period) and the relapse index (2 × number of injections administered + accumulation of exudate for 12 months post-PDT) were investigated. Results In PCV, the association between worse coverage and decreasing dry rates for feeder vessels and polyps approached statistical significance. With coverage margins ≥500 µm, dry rate tended to be greater than with coverage margins <500 µm for feeder vessels, classic lesions, and occult lesions on FA. In the tAMD group, coverage with margins ≥500 µm tended to yield a higher dry rate than coverage with margins <500 µm for CNV on IA. Coverage with margins ≥500 µm for occult and classic lesions on FA yielded no dry subjects, and all subjects with classic lesions or staining had recurrence (P = 0.009 and 0.050). Worse coverage and worse dry rate in PCV and worse relapse index in tAMD were related to pigment epithelial detachment on OCT (P = 0.040 and 0.006). Conclusion Polyps in PCV and pigment epithelial detachment (PED) in tAMD were verified as appropriate targets, corresponding to the existing guidelines, and feeder vessels, classic lesion, occult lesion, and PED in PCV and CNV on IA in tAMD were suggested as further targets. OCT was superior to FA for evaluating PED.

Abstract
Pachychoroid neovasculopathy (PNV) is treated with antivascular endothelial growth factor (VEGF) injection and photodynamic therapy (PDT), but no curative treatment has yet been established. We aimed to clarify the treatment results of a reduced dose of PDT for PNV. The subjects were 27 eyes of 27 patients (male:female = 20:7, mean age 58.9 years). PDT, at 2/3 of the conventional dose (2/3PDT), was administered once. The patients were then observed for one year. Eyes with polypoidal choroidal vasculopathy (PCV) were excluded. We investigated the associations among the central retinal thickness, choroidal thickness, and visual acuity changes before treatment and one, three, six and 12 months after PDT. When serous retinal detachment was increased or unchanged or new hemorrhages were observed, as compared with pretreatment findings, intravitreal injection of an anti-VEGF agent was performed. Visual acuity was significantly improved, as compared to before treatment, at three, six, and 12 months after 2/3PDT. Foveal retinal thickness was significantly decreased after versus before treatment in the 2/3PDT group (p < 0.001). Foveal choroidal thickness was also significantly reduced in the 2/3PDT group (p = 0.001). Additional intravitreal anti-VEGF agent injections were administered to three patients (11%), while 24 (89%) required no additional treatment during the one-year follow-up period. For PNV without polyps, 2/3PDT appears to be effective.

Abstract
Aging is associated with a number of histological changes in the choroid, Bruch's membrane, RPE, and neuroretina. Outside of the normal physiologic aging spectrum of changes, abnormal deposits such as basal laminar deposits, basal linear deposits, and soft drusen are known to be associated with AMD. Progression of AMD to advanced stages involving geographic atrophy, choroidal neovascularization, and/or disciform scars can result in debilitating vision loss. Knowledge of the angiogenic pathway and its components that stimulate neovascularization has led to the development of a new paradigm of intravitreal anti-VEGF pharmacotherapy in the management of neovascular AMD. Currently however, there are no available treatments for the modification of disease progression in non-neovascular AMD, or for the treatment of geographic atrophy. Further understanding of the histopathology of AMD and the molecular mechanisms that contribute to pathogenesis of the disease may reveal additional therapeutic targets.

Abstract
We investigated long-term treatment responses in patients with treatment-naïve polypoidal choroidal vasculopathy (PCV) undergoing photodynamic therapy (PDT) with intravitreal ranibizumab (IVR). The medical charts of 14 patients with treatment-naïve PCV who underwent PDT with IVR were retrospectively reviewed. Patients were followed up and treated with additional IVR for ≥3 years. Best-corrected visual acuity (BCVA), central foveal thickness (CFT), greatest linear dimension (GLD) on angiography, polyp regression and central choroidal thickness (CCT) were assessed. Associations between these functional or anatomic outcomes with age, baseline CCT, baseline GLD or choroidal vascular hyperpermeability (CVH) were investigated using univariate and multivariate analysis. Mean logMAR BCVA improved significantly at 3 years (0.34 ± 0.24 to 0.12 ± 0.29, p = 0.003). Greater BCVA improvement and longer time to first recurrence was significantly associated with CVH. Fewer number of IVR retreatment within 3 years was associated with thicker baseline CCT. Mean CCT significantly decreased at 3 years (217 ± 33 µm to 197 ± 48 µm, p = 0.003). Greater decrease of CCT was significantly associated both with greater number of IVR retreatment within 3 years and absence of CVH. These results showed that pachychoroid characteristics at baseline was associated long-term functional and anatomic outcomes in patients with treatment-naïve PCV who had undergone combination PDT and IVR.

Abstract
PURPOSE To investigate the long-term incidence and growth rate of chorioretinal atrophy (CRA) in patients with polypoidal choroidal vasculopathy (PCV) and determine the associated risk factors. METHODS The medical records of 88 patients with unilateral symptomatic PCV who received anti-vascular endothelial growth factor (anti-VEGF) injections with or without photodynamic therapy (PDT) were analyzed retrospectively. Near-infrared fundus imaging and spectral domain optical coherence tomography were used to measure the CRA area and growth rate. Kaplan-Meier survival analysis was performed to estimate the CRA incidence. Logistic and linear regression analyses were used to investigate risk factors (e.g., age, frequency of abnormal OCT findings, PDT history, total injection number, and choroidal thickness) associated with the CRA incidence and growth rate, respectively. RESULTS The overall CRA incidence was 40.8% at 5 years. The absence of subretinal fluid, the presence of intraretinal fluid, and a thin choroid were significant risk factors for CRA occurrence with a history of PDT. Overall 5-year CRA growth rate was 0.69 mm2/year. Faster CRA growth was significantly related to the presence of subretinal hyperreflective material and thin choroid. PDT history was not significantly related to CRA growth. CONCLUSIONS Thin choroid may be a significant risk factor for long-term development and growth of CRA in eyes with PCV. Intraretinal fluid seems to promote the development of CRA, while subretinal fluid seems to be associated with CRA prevention. The history of PDT was significantly related to the occurrence of CRA, but not to the growth rate of CRA.

Abstract
Purpose To introduce novel findings of polypoidal choroidal vasculopathy (PCV) via optical coherence tomography angiography (OCTA) Methods This study is a retrospective chart review of 16 patients (16 eyes) with PCV. OCTA (Avanti RTVue XR) findings were evaluated and selected for analysis after agreement by two retina specialists . Results Twenty one polyps in 16 eyes (16 patients) with PCV were included in this study. The mean patient age was 67 years (13 men and three women). The shape of polypoidal lesions on OCTA at initial were halo (five polyps), rosette (seven polyps), and vascular network (nine polyps). Eight months after anti-vascular endothelial growth factor treatment, in a total of four eyes, seven polyps could be followed up completely, the two halo type polypoidal lesions changed to rosette and vascular network type. The lesions of three rosette and two vascular network type lesions did not change in shape. In addition, the size of the polypoidal lesions (one among two halo types, two among three rosette types, and two among two vascular network types) decreased, but one halo type did not change and one rosette type increased in size on OCTA. Conclusions En-face OCTA enabled us to categorize novel types of PCV with polypoidal lesions.

Abstract
Polypoidal choroidal vasculopathy (PCV) is a retinal disorder commonly found in Asians presenting as neovascular age-related macular degeneration and is characterized by serous macular detachment, serous or hemorrhagic pigment epithelial detachment, subretinal hemorrhage, and occasionally visible orange-red subretinal nodular lesions. PCV is diagnosed using indocyanine green angiography (ICGA), and the lesions appear as polypoidal aneurysmal vascular lesions with or without abnormal branching vascular network. Although ICGA remains the gold standard for the diagnosis of PCV, various imaging modalities have also facilitated the diagnosis and monitoring of PCV. Recent advances in imaging technology including the use of high resolution spectral domain optical coherence tomography (OCT) and OCT angiography have provided new insights on the pathogenesis of PCV, suggesting a link between PCV and pachychoroid spectrum of macular disorders. With the evolving understanding on the pathogenesis and clinical characteristics of PCV, different therapeutic options have been proposed. These include intravitreal anti-vascular endothelial growth factor (anti-VEGF) monotherapy, combination therapy with anti-VEGF and verteporfin photodynamic therapy, and thermal laser photocoagulation. In recent years, major multi-center randomized clinical trials such as EVEREST, EVEREST II, and PLANET studies have been conducted to compare the efficacy and safety of various treatment options for PCV. This review aims to summarize the results of recent literature, clinical trials and studies to provide an update on the management options of PCV. An overall management strategy for PCV will also be proposed.

Int J Ophthalmol 2019; 12:51-57. [PMID: 30662840 DOI: 10.18240/ijo.2019.01.08] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2017] [Accepted: 09/06/2018] [Indexed: 12/11/2022] Open
Abstract
AIM To evaluate the real-life clinical outcomes of intravitreal injection of conbercept combined rescue therapy for polypoidal choroidal vasculopathy (PCV). METHODS This was an open label, single center, and interventional study. All enrolled patients were treated initially with three consecutive monthly intravitreal conbercept injections (0.5 mg). Additional conbercept injections were administered upon substantial polyp regression with improved visual acuity (VA). Eyes with partial or no polyp regression and poor VA were rescue treated with photodynamic therapy (PDT) for subfoveal polyps or thermal laser photocoagulation for extrafoveal polyps. Best-corrected visual acuity (BCVA), central foveal thickness (CFT) and polyp regression were observed as primary outcomes. Side effects were also collected during the follow-up period. RESULTS A total of 56 eyes (56 patients) with PCV were included. BCVA increased significantly from the baseline of 43.52±24.21 letters to 55.88±21.94 letters (P<0.001) at 12mo, while CFT decreased significantly from 457.41±207.86 µm to 247.98±127.08 µm (P<0.001). All patients showed polyp regression. Twenty-three eyes achieved complete polyp regression after the three initial injections, which increased to 44 eyes at 12mo. Seventeen eyes underwent rescue therapy, among which 2 eyes treated with PDT and 15 eyes treated with laser photocoagulation. A mean of 4.30±1.43 injections were given per eye. No intraocular inflammation, retinal or vitreous hemorrhage, or systemic complication occurred. CONCLUSION Conbercept is an effective and safe option for the treatment of PCV in Chinese population. The treatment regimen of three initial conbercept injections followed by additional injections or rescue therapies is efficacious for treating PCV.

Abstract
Purpose: The aim of the study was to analyze the outcomes of photodynamic therapy (PDT) with intravitreal anti-vascular endothelial growth factor (anti-VEGF) for patients with polypoidal choroidal vasculopathy (PCV) having visual acuity (VA) better than 20/60 in a real-world scenario in India. Methods: Retrospective review of 42 eyes of 40 patients (mean age 64.3 years) with best-corrected VA (BCVA) 20/60 or better and mean follow-up of 40 months (median 38 months; range 12–71 months) treated with PDT and anti-VEGF or triamcinolone for indocyanine green angiography (ICGA)-proven subfoveal PCV. Results: Mean BCVA improved from 0.22 logMAR at baseline to 0.15 at last visit (P < 0.001). On ICGA, polyp was observed in 42 eyes (100%) and branching vascular network (BVN) in 37 eyes (88.1%). Polyp regressed in 33 (78.6%) of 42 eyes and BVN in 26 (70.3%) of 37 eyes after combined therapy at 3 months. Mean greatest linear diameter reduced significantly (P < 0.001) from 7.22 mm to 4.11 mm. Standard-fluence PDT was performed in 35 eyes and reduced-fluence in 7 eyes. The mean number of PDT was 1.17 with mean number of injections being 6.38 at the end of follow-up. In five eyes, more than one PDT was administered. Of 42 eyes, 40 showed complete resolution of serous macular detachment (SMD) after the combined therapy at 3 months; 17 (42.5%) of the 40 eyes showed no recurrence of fluid on spectral domain optical coherence tomography till the last visit with a mean follow-up of 27 months. On long-term follow-up, SMD reoccurred in 23 eyes with a mean follow-up period of 9.64 ± 5.24 months. Of 38 eyes having a double-layer sign (DLS) on optical coherence tomography at baseline, 37 eyes were having regression of the DLS, that is, it either reduced or resolved at the final visit. At the final visit, 66.7% (P < 0.001) eyes were having fluid-free retina. No complication of subretinal hemorrhage was noted. Of the 42 eyes, only one eye had BCVA worse than 20/60 on the final visit. Conclusion: To the best of our knowledge, this is the first study to look into the long-term effect of combined PDT with anti-VEGF in PCV in eyes having good VA. Long-term effect of combined PDT appears to be a safe and effective treatment for PCV in eyes having good VA with better outcomes in real-world setting. This study further strengthens the superiority of the combined treatment modality for treatment of subfoveal PCV with no or minimal risk of complication on long-term follow-up.

Abstract
Polypoidal choroidal vasculopathy (PCV) is increasingly recognized as an important cause of exudative maculopathy in Asians as against Wet age-related macular degeneration in Caucasians. A panel of retinal experts methodically evaluated pertinent updated literature on PCV with thorough PubMed/MEDLINE search. Based on this, the panel agreed upon and proposed the current consensus recommendations in the diagnosis (clinical and imaging), management and follow-up schedule of PCV. Diagnosis of PCV should be based on the gold standard indocyanine green angiography which demonstrates early nodular hyperfluorescence signifying the polyp with additional features such as abnormal vascular network (AVN). Optical coherence tomography is an excellent adjuvant for diagnosing PCV, monitoring disease activity, and decision-making regarding the treatment. Current treatment modalities for PCV include photodynamic therapy, anti-vascular endothelial growth factor agents, and thermal laser. Choice of specific treatment modality and prognosis depends on multiple factors such as the location and size of PCV lesion, presence or absence of polyp with residual AVN, amount of submacular hemorrhage, presence or absence of leakage on fundus fluorescein angiography, visual acuity, and so on. Current recommendations would be invaluable for the treating physician in diagnosing PCV and in formulating the best possible individualized treatment strategy for optimal outcomes in PCV management.

Clinical outcomes in Caucasian patients with polypoidal choroidal vasculopathy. Eye (Lond) 2018; 32:1731-1739.

Abstract
PURPOSE To describe treatment outcomes in a cohort of Caucasian patients with polypoidal choroidal vasculopathy (PCV). METHODS Clinical charts from 48 eyes of 45 Caucasian patients with PCV were retrospectively reviewed. All cases were diagnosed with indocyanine green angiography. Best corrected visual acuity (BCVA) and optical coherence tomography (OCT) imaging were analyzed at baseline and final follow-up. RESULTS Eyes were treated with a combination of verteporfin photodynamic therapy (PDT) and anti-vascular endothelial growth factor (VEGF) (n = 24), or PDT monotherapy (n = 9), or anti-VEGF monotherapy (n = 8), or no treatment (n = 7). Aflibercept was the anti-VEGF agent in 30 out of 32 eyes. Sixteen out of 24 eyes in the combination treatment group received initial PDT at diagnosis. All treatments led to stabilization of BCVA at final visit with a trend for better visual acuity in the anti-VEGF monotherapy group. There was a substantial reduction in central retinal thickness associated with resolution of subfoveal fluid and improvement in retinal pigment epithelial detachment in all treatment groups. BCVA and OCT findings remained stable in eyes which received no treatment. The use of PDT was associated with 0.5 fewer intravitreal injections per annum, which was not statistically significant. CONCLUSIONS In the largest series of Caucasian patients with PCV presented to date, anti-VEGF monotherapy, PDT, or their combination preserved visual acuity and improved subfoveal exudative changes. Combination treatment was not superior to anti-VEGF monotherapy.

Abstract
INTRODUCTION Polypoidal choroidal vasculopathy (PCV) is a choroidal pathology characterized by frequent occurrences of subretinal hemorrhages and resistance to monotherapies such as ranibizumab or bevacizumab intravitreal injections (IVT). The purpose of this study is to evaluate both the anatomical and functional efficacy of aflibercept IVT as a monotherapy in PCV in a Caucasian population. METHODS We conducted a prospective multicenter study in either treatment-naïve patients with PCV or PVC patients who had not been treated with anti-VEGF within the previous 3 months or with photodynamic therapy (PDT) within the previous 6 months. All patients had been treated with 3 initial monthly loading doses of aflibercept followed by a Q8 regimen for 28 weeks in total. All patients underwent a complete ophthalmic examination including the measurement of best-corrected visual acuity (BCVA) before each IVT and after 28 weeks as well as an optical coherent tomography (OCT) of the macula. At baseline and 28 weeks, the polypoidal dilations were analyzed with indocyanine green angiography. RESULTS Thirty-four eyes of 34 patients were included in this study. All patients were followed for 28 weeks and received 5 aflibercept IVT. The mean baseline BCVA was 55 letters. After 28 weeks, significant +13 letters in BCVA and a regression of exudative signs on OCT in all patients were observed. In 62% of the cases, polyp disappearance was observed on indocyanine green angiography. DISCUSSION In this study on a Caucasian population, we showed that aflibercept as a monotherapy provided both a significant visual gain and the regression of polypoidal dilations. Aflibercept use in monotherapy may contribute to reduce the hemorrhagic risk and atrophy linked to PDT.

Abstract
PURPOSE To evaluate the incidence, outcomes, and risk factors for hemorrhagic complications in eyes with polypoidal choroidal vasculopathy (PCV) following photodynamic therapy (PDT). METHODS Medical records of 94 eyes of 86 consecutive patients with PCV who underwent PDT between January 2007 and December 2014 were retrospectively reviewed. The diagnosis of PCV was based on clinical features and indocyanine green angiography. Eyes were treated with PDT monotherapy or a combination of PDT plus anti-vascular endothelial growth factor. PDT was performed at (standard [SFPDT] or reduced fluence RFPDT). RESULTS Ninety-four eyes had 119 PDT treatment sessions (mean: 1.3 sessions). Mean presenting vision was 0.46 ± 0.44 logarithm of the minimum angle of resolution (logMAR). Following PDT, ten eyes (11%) of nine patients had hemorrhagic complications such as subretinal hemorrhage (SRH; n = 5), subretinal pigment epithelium (RPE) hemorrhage (n = 1), breakthrough vitreous hemorrhage (BVH; n = 3), and SRH with sub-RPE hemorrhage and BVH (n = 1). Median interval to hemorrhage following PDT was 2 months. Age (P = 0.842), duration of symptoms (P = 0.352), number of laser spots (P = 0.219), and laser spot size (LSS) (P = 0.096) were not significantly associated with increased risk of hemorrhagic complications. Female gender was associated with reduced risk of hemorrhage (P = 0.045). SFPDT was significantly associated with increased risk of hemorrhage (P = 0.026). The probability of developing hemorrhagic complications in SFPDT group was 0.24 compared to 0.07 in RFPDT group (P = 0.039). Multivariate logistic regression analysis showed SFPDT as the only significant risk factor for hemorrhage following PDT (odds ratio 5.3, 95% confidence interval 1.1-24.8, P = 0.03). Mean final vision was 0.61 ± 0.53 logMAR at mean follow-up of 33 months (median = 22 months; range = 2-157 months). CONCLUSION Age, LSS, number of laser spots, preexisting hemorrhages, or use of anticoagulants were not associated with increased risk of hemorrhagic complications. SFPDT was significantly associated with increased risk of hemorrhagic complications in such eyes.

Abstract
AIMS The aim was to study the efficacy of combined therapy with reduced-fluence photodynamic therapy (RFPDT) and intravitreal bevacizumab/ranibizumab from the Indian subcontinent. SETTINGS AND DESIGN This was a single-center, retrospective interventional study. METHODS Thirty-five eyes of 34 patients diagnosed with polypoidal choroidal vasculopathy were included. All the patients underwent RFPDT, followed by intravitreal bevacizumab/ranibizumab. STATISTICAL ANALYSIS USED SPSS software, version 17.0 (SPSS Inc., Chicago, IL, USA) was used to compare the logarithm of the minimal angle of resolution visual acuity at presentation and final follow-up. P< 0.05 was considered statistically significant. RESULTS Regression of polyps after a single session of RFPDT was seen in five eyes; multiple sessions of treatment were required in thirty eyes. An average number of intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections given were 4 ± 1.9 and average number of PDT sessions were 1.2 ± 0.5. Visual acuity improvement was seen in 21 (60%) eyes (P < 0.001), decrease in visual acuity was seen in 7 (20%) eyes (P = 0.016), and in 7 eyes (20%), vision remained stable. Regression of polypoidal lesions was seen in 80% of cases. No complications of massive subretinal hemorrhage or breakthrough vitreous hemorrhage were noted in our patients. The mean follow-up period was 18 months (range, 12-24 months). CONCLUSIONS RFPDT with anti-VEGF is safe and effective treatment with polyp regression and vision improvement in 80% of cases, without any complication of subretinal hemorrhage/vitreous hemorrhage.

Abstract
PURPOSE The aim of this study was to study the angiopathic findings of ranibizumab-resistant polypoidal choroidal vasculopathy after switching to a treat-and-extend regimen with intravitreal aflibercept. METHODS The authors retrospectively reviewed 17 eyes of 17 Japanese patients with polypoidal choroidal vasculopathy (10 men and 7 women, age: 73.8 ± 7.4 years) who were treated with intravitreal aflibercept (2 mg/0.05 mL) injections from February 2013 to August 2014 at Tokyo University Hospital. All patients had switched to aflibercept because their polypoidal choroidal vasculopathy had been refractory to ranibizumab. RESULTS The mean logMAR best-corrected visual acuity at baseline and after 12 months of therapy was 0.30 ± 0.29 (Snellen equivalent: 20/40) and 0.17 ± 0.26 (20/30) (paired t-test P < 0.001). Visual acuity remained stable in 5 cases (29%), deteriorated in 3 (18%), and improved in 9 (53%). Branching vascular networks persisted in all 17 eyes but shrank in 15 (88%). The mean lesion diameter was 3329 ± 1261 μm at baseline and 3180 ± 1247 μm after 12 months (P = 0.0002). CONCLUSION A treat-and-extend regimen with intravitreal aflibercept for ranibizumab-resistant patients resulted in branching vascular network shrinkage over a 1-year period.

Abstract
Background: Polypoidal choroidal vasculopathy (PCV) is characterized by the presence of polyps with or without a branching vascular network and more prevalent among Asians. The aim of this study was to compare the outcomes of conbercept therapy between two different angiographic subtypes of PCV. Methods: Fifty-eight patients of PCV were classified into two phenotypes according to indocyanine green angiography (ICGA). In Type 1, both feeder and draining vessels are visible on ICGA and network vessels are numerous. In Type 2, neither feeder nor draining vessels are detectable, and the number of network vessels is small. The patients were treated with intravitreal conbercept (IVC) for 3 months. Additional IVC was given at subsequent monthly visits, if needed. The patients were followed up for 12 months, and changes in mean best-corrected visual acuity (BCVA), central retinal thickness (CRT), subretinal fluid (SRF) thickness, pigmented epithelial detachment (PED), hemorrhage, and number of polypoidal lesions were evaluated. Results: The mean BCVA in Type 2 PCV (15.92 ± 9.76 letters) achieved a significantly greater improvement than that in the Type 1 (14.10 ± 9.07 letters) at month 12 (t = 2.37, P < 0.01). Moreover, the mean CRT decrease was numerically greater in Type 2 (120.44 ± 73.81 μm) compared with Type 1 (106.48 ± 72.33 μm) at month 6 (t = 4.31, P < 0.01), and greater in Type 2 (130.21 ± 76.28 μm) compared with Type 1 (111.67 ± 79.57 μm) at month 9 (t = 1.87, P < 0.01). There was no significant difference between the two types for the decrease in SRF thickness, PED height, and regression of polyps from month 3 to 12 (t = 2.97, P > 0.05). Conclusion: Classification systems for PCV will show differences in presentation, natural history, or response to anti-vascular endothelial growth factor treatment and might, therefore, provide a new key to the choice of treatment for the disease.

Abstract
PURPOSE To evaluate the efficacy and adverse effects of using low-dose intravitreal triamcinolone acetonide (IVTA) to preserve vision in polypoidal choroidal vasculopathy (PCV) eyes. METHODS This retrospective chart review study examined 8 eyes of 7 PCV patients, for whom verteporfin photodynamic therapy (vPDT) or antivascular endothelial growth factor (VEGF) therapy was not affordable/available and also with intolerable risk because of underlying cardiovascular and/or cerebrovascular ischemia. Low-dose IVTA (1 mg/0.025 mL) monotherapy was administered and repeated every 4 weeks if intraretinal edema or subretinal fluid persisted. RESULTS The median follow-up time was 26.4 months. Three eyes (3/8) maintained their initial best-corrected visual acuity and 4 eyes (4/8) exhibited improvement, whereas 1 eye (1/8) sustained some loss. The mean injection number per month was 0.7 for the first 6 months, after which it decreased to 0.4. In regard to adverse effects, intraocular pressure (IOP) of more than 21 mmHg was noted as persisting for a few weeks in 4 eyes and that of more than 30 mmHg was noted once in 1 eye. The increased IOP was adequately controlled by using IOP-lowering agents. Two initially phakic eyes each underwent cataract surgery in the 12th and 14th months after treatment. CONCLUSIONS Low-dose IVTA therapy may be valuable for preserving the vision of PCV patients, while vPDT or anti-VEGF is not affordable/available or of those with underlying diseases for whom anti-VEGF therapy is with intolerable risk.

Abstract
PURPOSE To evaluate the efficacy of different doses of conbercept in patients with polypoidal choroidal vasculopathy in the AURORA study. METHODS Retrospective subgroup analyses of 12-month data from the AURORA study. Fifty-three patients (32 in 0.5-mg group and 21 in 2.0-mg group) diagnosed with polypoidal choroidal vasculopathy in AURORA study were retrospectively evaluated. Efficacy outcomes were compared between the two dosage groups. RESULTS At Month 12, mean changes in best-corrected visual acuity from baseline were 14.4 ± 14.1 letter scores for the 0.5-mg group and 14.2 ± 21.0 letter scores for the 2.0-mg group; mean central retinal thickness decreased by 104.5 ± 127.3 μm in the 0.5-mg group and 140.7 ± 127.9 μm in the 2.0-mg group; mean total macular volume decreased by 0.9 ± 2.3 mm and 1.0 ± 1.2 mm in the 0.5-mg and 2.0-mg groups, respectively. The mean subretinal fluid thickness decreased by 111.9 ± 122.5 μm and 76.3 ± 112.6 μm in the 0.5-mg and 2.0-mg groups, respectively. The mean pigment epithelial detachment height decreased by 79.3 ± 217.8 μm and 61.3 ± 161.5 μm in the 0.5-mg and 2.0-mg groups, respectively. The mean area of polyps decreased by 0.46 ± 0.76 mm and 0.55 ± 1.34 mm in the 0.5-mg and 2.0-mg groups, respectively. The mean total lesion area decreased by 2.51 ± 5.94 mm (P = 0.088) and 4.62 ± 5.51 mm in the 0.5-mg group and 2.0-mg groups, respectively. Complete regression of polyps was observed in 56.5% of patients in the 0.5-mg group and 52.9% of those in the 2.0-mg group, whereas partial regression was observed in 26.1% and 35.3% of patients in the 0.5-mg and 2.0-mg groups, respectively. CONCLUSION Intravitreal injection of conbercept appears to significantly improve visual acuity and anatomical outcomes in patients with polypoidal choroidal vasculopathy.

Abstract
PURPOSE To evaluate the 1-year results of intravitreal aflibercept injections for polypoidal choroidal vasculopathy based on indocyanine green angiography findings. METHODS Twenty-nine eyes with treatment-naive polypoidal choroidal vasculopathy treated with intravitreal aflibercept injections and followed longer than 1 year were retrospectively reviewed. The best-corrected visual acuity, optical coherence tomography findings, and polypoidal lesions in indocyanine green angiography were evaluated. RESULTS The mean number of injections through 1 year was 3.9 ± 1.9 (range: 1-8). Fourteen eyes (48%) were received no additional injections because of no recurrence of exudative change after the first loading dose. The mean best-corrected visual acuity levels at 6 months and 1 year significantly improved, and the mean central retinal thickness significantly decreased at all observation points from the baseline. At 3 months, the polypoidal lesions completely resolved in 19 (66%) eyes. At 1 year, the complete resolution of polypoidal lesions was seen in 4 of 10 eyes with persistent polypoidal lesions at 3 months. However, polypoidal lesions recurred at 1 year in 5 of 19 eyes (26%) with complete resolution of polypoidal lesions at 3 months. CONCLUSION Aflibercept is effective for the eyes with treatment-naive polypoidal choroidal vasculopathy to achieve the resolution of polypoidal lesions. The authors need to carefully observe the eyes after confirming complete resolution of polypoidal lesion because of recurrent polyps seen in one-quarter of the study eyes.

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
PURPOSE To evaluate the 3-year outcome in eyes with polypoidal choroidal vasculopathy (PCV) treated with photodynamic therapy with verteporfin. METHODS Retrospective study and review of the literature. We performed a retrospective study of patients with PCV who were treated with photodynamic therapy between January 2007 and December 2008. Patients were excluded if they had received photodynamic therapy before the study period, but those who received previous treatment with other modalities (thermal laser or intravitreal therapies) were allowed. The main outcome measures were best-corrected visual acuity, repeat photodynamic therapy, and recurrence of PCV at the end of Years 1, 2, and 3. We further conducted a systematic review of the literature using the terms "polypoidal choroidal vasculopathy" and "photodynamic therapy" and compared the visual outcome of studies over 3 years using meta-analytical methods. RESULTS The retrospective study included 68 eyes. The mean best-corrected visual acuity was 0.73 ± 0.56 logMAR (20/107, Snellen equivalent) at baseline, 0.73 ± 0.70 logMAR (20/107, Snellen equivalent) at 1 year, 0.96 ± 0.76 logMAR (20/182, Snellen equivalent) at 2 years, and 1.07 ± 0.81 logMAR (20/235, Snellen equivalent) at 3 years. The cumulative recurrence rates of PCV were 16.1% (1 year), 34.9% (2 years), and 52.7% (3 years) and eyes with recurrence were more likely to suffer ≥3 lines loss compared with eyes without recurrence (63.2 vs. 17.6%, P = 0.006). The systematic review summarized results from 48 published studies and our retrospective study. The pooled analysis from 29 studies (316 eyes reporting the 3-year visual outcome) reported mean best-corrected visual acuity improvement of 0.115 logMAR at 1 year (n = 1,669), 0.066 logMAR at 2 years (n = 701), and 0.027 logMAR at 3 years (n = 316). Reported recurrence rates were 5.9% to 50.0% after 1 year, 9.1% to 83.3% after 2 years, and 40.0% to 78.6% after 3 years or longer of follow-up. CONCLUSION The visual outcome in eyes with PCV was stable until 2 years, but the outcome at 3 years worsened, particularly in eyes that experienced recurrence.

Abstract
PURPOSE To investigate 1-year outcomes of intravitreal aflibercept for polypoidal choroidal vasculopathy (PCV). DESIGN Retrospective, multicenter, consecutive case series. PARTICIPANTS A total of 90 eyes of 87 patients with treatment-naïve PCV followed at 3 tertiary centers. METHODS Clinical records were reviewed and imaging studies were analyzed of eyes with PCV that underwent 3 consecutive monthly aflibercept injections followed by injections every 2 months. Additional (rescue) injections were performed for worsening. MAIN OUTCOME MEASURES Best-corrected visual acuity (BCVA), optical coherence tomography (OCT), and angiographic findings at 1 year. RESULTS The mean BCVA (logarithm of the minimum angle of resolution units) of the 90 eyes improved from 0.31 at baseline to 0.17 at 12 months (P < 0.001). The mean central retinal thickness decreased from 315 μm at baseline to 204 μm at 12 months (P < 0.001). At 12 months, 64 eyes (71.1%) achieved a dry macula, defined as absence of intraretinal or subretinal fluid on OCT. Of 83 eyes that underwent indocyanine green angiography at both baseline and 12 months, 46 (55.4%) showed complete and 27 (32.5%) showed partial resolution of polypoidal lesions. Eleven of 82 eyes (13.4%) showed decreased size of branching choroidal vascular networks. CONCLUSIONS Intravitreal aflibercept administered over 1 year improved both visual acuity and macular morphology in a large number of treatment-naïve eyes with PCV.

Abstract
PURPOSE To report on a series of white patients in the United States with polypoidal choroidal vasculopathy (PCV). METHODS This is a retrospective chart review of 27 patients at a single center with PCV. RESULTS The mean age was 74.3 with 48% being male. The most common presenting diagnosis was exudative age-related macular degeneration in 59%, and it took 17.5 months to diagnose PCV. During this time, patients received one antivascular endothelial growth factor injection every 1.3 months. The most common reason for suspecting PCV was a large retinal pigment epithelial detachment or a poor response to antivascular endothelial growth factor therapy. Once PCV was diagnosed, most underwent photodynamic therapy. In those who received photodynamic therapy, the fluid and/or age-related macular degeneration decreased in 86%. The vision improved in 41% with 36% maintaining stable vision. Patients received only one additional injection every 3.95 months after photodynamic therapy. CONCLUSION This is one of the larger series of PCV in an entirely white population. It emphasizes the importance of diagnosis in whites as PCV can masquerade as recalcitrant exudative age-related macular degeneration. Common findings were a temporal or peripapillary location and the presence of lipid. After photodynamic therapy, the patients still required antivascular endothelial growth factor therapy, but the injection burden was decreased by 67% and vision was found to be improved or maintained in 77% of patients.

Abstract
PURPOSE To evaluate the functional and morphologic outcomes of patients with polypoidal choroidal vasculopathy who underwent intravitreal aflibercept treatment. METHODS We prospectively studied all the treatment-naive patients with polypoidal choroidal vasculopathy who were scheduled to undergo intravitreal aflibercept between February 2013 and July 2013. The best-corrected visual acuity was compared before treatment and at 6 months after the initial treatment. Changes in the central foveal thickness, choroidal thickness, presence/absence of subretinal fluid, fibrin, pigment epithelial detachment, and subretinal hemorrhage were also evaluated. The regression of the polyps was assessed using indocyanine green angiography. RESULTS A total of 16 patients were included in this study. A significantly better best-corrected visual acuity at 6 months was seen, compared with that at baseline (P = 0.041). The mean central foveal thickness significantly decreased from 417 ± 127 μm to 187 ± 50 μm (P < 0.001). The mean choroidal thickness also significantly decreased from 250 ± 63 μm to 217 ± 64 μm (P = 0.011). Overall, a complete resolution was obtained in 93.3% (14/15) of the cases with subretinal fluid, 75.0% (3/4) of the cases with fibrin, and 88.9% (8/9) of the cases with subretinal hemorrhage. Fifty-six percent (5/9) of the cases with pigment epithelial detachment obtained a complete improvement, whereas 33.3% (3/9) exhibited a partial decrease. The rate of polyp regression was 75.0% (12/16). CONCLUSION Intravitreal aflibercept was well tolerated and had improved the vision of treatment-naive patients with polypoidal choroidal vasculopathy when it was evaluated at short-term follow-up examinations. Intravitreal aflibercept might be associated with a high possibility of achieving involution of polyps and reducing exudative findings.

Abstract
BACKGROUND AND OBJECTIVE To evaluate the effect of reduced-fluence photodynamic therapy (PDT) on polypoidal choroidal vasculopathy (PCV) unresponsive to intravitreal ranibizumab. PATIENTS AND METHODS Patients with PCV unresponsive to ranibizumab administered 3 months consecutively who then received reduced-fluence PDT were retrospectively surveyed. Nonresponders were defined as patients having no reduction in intraretinal and/or subretinal fluid after 3 consecutive treatments. RESULTS In total, 22 of 104 eyes (21.2%) were non-responders, and 16 of 22 nonresponders received reduced-fluence PDT. Nine eyes achieved complete fluid resolution, and six had reduced but persistent fluid. In one eye, fluid persisted at 6 months despite an additional anti-vascular endothelial growth factor (anti-VEGF) injection after reduced-fluence PDT. Mean macular thickness decreased significantly at 3 and 6 months after PDT, but the mean visual acuity was worse than baseline. CONCLUSION Reduced-fluence PDT in nonresponders gradually decreased intraretinal and/or subretinal fluid over several months but did not maintain visual acuity.

Abstract
AIM To evaluate the efficacy and safety of three consecutive monthly injections of intravitreal ranibizumab for the treatment of polypoidal choroidal vasculopathy (PCV) in Korea. METHODS A retrospective chart review of 25 patients (27 eyes) with PCV was conducted. Patients received three initial monthly intravitreal injections (0.5 mg) of ranibizumab and were monitored monthly for 12mo between January 2010 and October 2011. Reinjection of ranibizumab after three initial monthly loading was administered on an as-needed basis, guided by the optical coherence tomography (OCT), fluorescein angiography (FA) and indocyanine green angiography (ICGA). The main outcomes were the changes of the mean best corrected Snellen visual acuity (VA), central macular thickness (CMT) by OCT, the changes of polyps and branching vascular network by FA and ICGA, and total number of injections received by patients during the 12mo. RESULTS The mean best corrected Snellen visual acuities at baseline, 1, 3, 6 and 12mo after primary injection were 0.77±0.59, 0.76±0.53, 0.70±0.47, 0.63±0.43, 0.61±0.43, 0.62±0.42 logMAR, respectively, and showed significant improvement at 3, 6, 12mo (P=0.003, P=0.002, P=0.018, Wilcoxon signed-rank test). The mean CMT at baseline, 1, 2, 3, 6, and 12mo was 312.41±66.38 µm, 244.59±71.47 µm, 232.32±69.41 µm, 226.69±69.03 µm, 228.62±37.07 µm, 227.59±51.01 µm respectively, and showed significant reduction (all P<0.001, Wilcoxon signed-rank test). Polypoidal lesions resolved on ICGA in 3 eyes (11.1%) and a branching vascular network remained in all 24 eyes (88.9%). A total of 106 injections were given in the 12-month period, which equaled to a mean of 3.92 (range, 3-6) times. Sixteen of the 27 treated eyes had additional 1.56±0.91 injections. The others (11 eyes) had just 3 consecutive injections. CONCLUSION An initial loading dose of three monthly ranibizumab injections is a safe and effective method in treating PCV, with visual and anatomical improvement over one year follow-up.

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
BACKGROUND This study aimed to demonstrate the phenotypic and genotypic factors associated with photodynamic therapy (PDT) for age-related macular degeneration (AMD). METHODS The study included 149 patients with exudative AMD treated by PDT. Eight phenotypic factors and ten genotypic factors for three single nucleotide polymorphisms (SNPs; rs800292, rs1061170, rs1410996) in the complement factor H (CFH) gene, rs 11200638-SNP in the high temperature requirement A-1 (HTRA1) gene, two SNPs (rs699947, rs2010963) in the vascular endothelial growth factor (VEGF) gene, and four SNPs (rs12948385, rs12150053, rs9913583, rs1136287) in the pigment epithelium-derived factor (PEDF) gene were evaluated. RESULTS A significant association with best-corrected visual acuity change was demonstrated in the greatest linear dimension, presence or absence of pigment epithelial detachment, and HTRA1-rs11200638 genotype statistically (P=3.67×10(-4), 1.95×10(-2), 1.24×10(-3), respectively). Best-corrected visual acuity in patients with AA genotype of HTRA1-rs11200638 significantly decreased compared with that in patients with GG genotype (P=1.33×10(-3)). Logistic regression analyses demonstrated HTRA1-rs11200638 genotype was most strongly associated with best-corrected visual acuity outcome from baseline at 12 months after photodynamic therapy (P=4.60×10(-3); odds ratio 2.363; 95% confidence interval 1.303-4.285). CONCLUSION The HTRA1-rs11200638 variant showed the most significant association. Therefore, this variant may be used as a prognostic factor to estimate the PDT response with significant predictive power.

Abstract
The quarter century since the foundation of the Royal College of Ophthalmologists has coincided with immense change in the subspecialty of medical retina, which has moved from being the province of a few dedicated enthusiasts to being an integral, core part of ophthalmology in every eye department. In age-related macular degeneration, there has been a move away from targeted, destructive laser therapy, dependent on fluorescein angiography to intravitreal injection therapy of anti-growth factor agents, largely guided by optical coherence tomography. As a result of these changes, ophthalmologists have witnessed a marked improvement in visual outcomes for their patients with wet age-related macular degeneration (AMD), while at the same time developing and enacting entirely novel ways of delivering care. In the field of diabetic retinopathy, this period also saw advances in laser technology and a move away from highly destructive laser photocoagulation treatment to gentler retinal laser treatments. The introduction of intravitreal therapies, both steroids and anti-growth factor agents, has further advanced the treatment of diabetic macular oedema. This era has also seen in the United Kingdom the introduction of a coordinated national diabetic retinopathy screening programme, which offers an increasing hope that the burden of blindness from diabetic eye disease can be lessened. Exciting future advances in retinal imaging, genetics, and pharmacology will allow us to further improve outcomes for our patients and for ophthalmologists specialising in medical retina, the future looks very exciting but increasingly busy.

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
PURPOSE To compare the 3-year visual outcome after double therapy of photodynamic therapy (PDT) with intravitreal bevacizumab (IVB) and triple therapy of PDT combined with IVB and subtenon triamcinolone acetonide (STTA) injections for polypoidal choroidal vasculopathy (PCV). DESIGN Retrospective, comparative, interventional case series. METHODS Medical records for 36 eyes in 36 patients (33 men, 3 women; mean age 73.5 years old; range 63-82 years old) with treatment-naive subfoveal PCV were reviewed retrospectively. Of the 36 eyes, 17 were treated with double therapy and 19 with triple therapy. RESULTS The change in visual acuity after triple therapy was significantly better than that after double therapy (p<0.05). At 36 months, improvement in visual acuity was seen in 5 eyes (29.4%) in the double therapy group and 10 eyes (52.6%) in the triple therapy group. Retreatment using the initial treatment was performed for six eyes (35.3%) in the double therapy group and five eyes (26.3%) in the triple therapy group, and treatment-free period was significantly longer in the triple therapy group (p<0.05). The mean number of additional antivascular endothelial growth factor therapy was higher in the double therapy group. Post-treatment vitreous haemorrhage or retinal pigment epithelium tear occurred only in the double therapy group, in one eye (5.9%) and one eye (5.9%), respectively. CONCLUSIONS Initial therapy consisting of a single session of PDT combined with IVB and STTA improves vision in treatment-naive subfoveal PCV. Compared with double therapy, this triple therapy may be more effective for PCV.

Abstract
Purpose To compare the 1-year results of intravitreal ranibizumab combined with reduced-fluence photodynamic therapy (RF-PDT) to intravitreal ranibizumab (IVR) alone for eyes with polypoidal choroidal vasculopathy (PCV). Methods We reviewed the medical records from 47 consecutive patients with PCV (47 naïve eyes). Seventeen eyes from 17 patients had one IVR treatment combined with RF-PDT followed by two additional IVR treatments (combined group), and 30 eyes from 30 patients were treated with 3 monthly IVR treatments (IVR group). All eyes had a follow-up period of at least 12 months. Results At 12 months, the mean logarithm of the minimal angle of resolution (logMAR) best-corrected visual acuity (BCVA) significantly improved from 0.55 to 0.38 logMAR units in the combined group (P=0.041) but did not change significantly in the IVR group (P=0.371). The central foveal thickness (CFT) was significantly thinner in both groups at 6 months (P<0.01). Additional IVR injections were required less frequently in the combined group (n=3; 17%) than in the IVR group (n=16; 53%) during the 12 month follow-up (P=0.029). Conclusion The IVR and RF-PDT combination led to significant BCVA improvements and required fewer additional IVR treatments for at least 12 months in eyes with PCV.

Abstract
BACKGROUND Polypoidal choroidal vasculopathy (PCV) is an exudative maculopathy affecting vision, with clinical features distinct from neovascular age-related macular degeneration. Currently, no evidence-based guidelines exist for its diagnosis and treatment. METHODS A panel of experts analyzed a systematic literature search on PCV together with results of the EVEREST trial, the only published randomized controlled clinical trial in PCV. At a subsequent Roundtable meeting, recommendations for the management of PCV were agreed based on this analysis and their own expert opinion. RESULTS Diagnosis of PCV should be based on early-phase nodular hyperfluorescence from choroidal vasculature visualized using indocyanine green angiography. Recommended initial treatment of juxtafoveal and subfoveal PCV is either indocyanine green angiography-guided verteporfin photodynamic therapy or verteporfin photodynamic therapy plus 3 × 0.5 mg ranibizumab intravitreal injections 1 month apart. If there is incomplete regression of polyps by indocyanine green angiography, eyes should be retreated with verteporfin photodynamic therapy monotherapy or verteporfin photodynamic therapy plus ranibizumab. If there is complete regression of polyps by indocyanine green angiography, but there is leakage on fluorescein angiography and other clinical or anatomical signs of disease activity, eyes should be retreated with ranibizumab. CONCLUSION Practical guidance on the clinical management of PCV is proposed based on expert evaluation of current evidence.

Abstract
PURPOSE To report a combined intravitreal treatment for submacular hemorrhage. METHODS This retrospective, noncomparative, interventional case series included 7 patients with neovascular age-related macular degeneration and 2 with idiopathic polypoidal choroidal vasculopathy, presenting with fovea-involving submacular hemorrhage ≥ 4 disk areas in size, of <10 days of duration. All patients received a single 0.05-mL intravitreal injection of 50 μg alteplase, 0.3 mL of 100% C3F8, and facedown positioning for 1 week. Patients with newly diagnosed age-related macular degeneration received 3 consecutive monthly intravitreal injections of 0.5 mg ranibizumab, followed by monthly retreatment as needed. Those with idiopathic polypoidal choroidal vasculopathy were treated with photodynamic therapy. RESULTS Mean (± SD) logarithm of the minimum angle of resolution visual acuity improved from 0.75 ± 0.35 at presentation to 0.35 ± 0.30 at a mean final follow-up of 15.1 months (P = 0.0078). Median Snellen acuity improved from 20/200 to 20/32. Visual acuity was stable in one case and improved in eight. The average size of submacular hemorrhage was 6.8 disk areas at presentation, reducing to 2.6 within 1 month (P = 0.0039). Subfoveal hemorrhage was displaced in all cases within 9 weeks. The mean pretreatment central retinal thickness of 669 μm reduced to 528 μm (P = 0.0039). One case developed transiently elevated intraocular pressure. Two developed breakthrough vitreous hemorrhage. No adverse events were attributed to tissue plasminogen activator. CONCLUSION Tissue plasminogen activator and C3F8, combined with intravitreal ranibizumab or photodynamic therapy, may result in anatomical clearance of submacular hemorrhage and improved visual acuity, in a condition with an otherwise poor visual prognosis.

Abstract
PURPOSE To compare the effect of photodynamic therapy (PDT) and intravitreal ranibizumab in patients with polypoidal choroidal vasculopathy (PCV). DESIGN Randomized clinical trial. METHODS SETTING Multicenter. STUDY POPULATION Total of 93 patients with treatment-naïve PCV. INTERVENTION Patients were randomized to 2 arms. Patients in the PDT arm underwent a single session of PDT with verteporfin, and patients in the ranibizumab arm received 3 monthly ranibizumab injections at baseline. Additional treatment was performed as needed in each arm. MAIN OUTCOME MEASURES Primary outcome measurement was the proportion of patients gaining or losing more than 0.2 logarithm of minimal angle of resolution (logMAR) units from baseline. Mean change of logMAR and central retinal thickness (CRT) were also evaluated. RESULTS In the PDT arm (n = 47), 17.0% achieved visual acuity gain, 55.3% had no change, and 27.7% experienced visual acuity loss. The results were 30.4%, 60.9%, and 8.7%, respectively, in the ranibizumab arm (n = 46), significantly better than the PDT arm (P = .039). In the PDT arm, mean CRT improved (366.8 ± 113.6 μm to 289.1 ± 202.3 μm, P < .001), but logMAR was unchanged (0.57 ± 0.31 to 0.62 ± 0.40). The ranibizumab arm demonstrated improvement in both CRT (418.9 ± 168.6 μm to 311.2 ± 146.9 μm, P < .001) and logMAR (0.48 ± 0.27 to 0.39 ± 0.26, P = .003). Mean change of logMAR was also greater in the ranibizumab arm (P = .011). CONCLUSION Intravitreal injection of ranibizumab is more effective than PDT for treatment-naïve PCV.

Abstract
PURPOSE To evaluate the functional outcomes of patients with polypoidal choroidal vasculopathy (PCV) who underwent intravitreal ranibizumab (IVR) treatment, compared with photodynamic therapy (PDT), after at least 2 years. METHODS We retrospectively studied all the treatment-naïve patients with PCV who were scheduled to undergo IVR or PDT between August 2005 and June 2010. All the patients who had a 2-year or longer follow-up period were included in the study. The best-corrected visual acuity (BCVA) in the two groups was compared before treatment and at 3, 6, 12, 18 and 24 months after the initial treatment. The regression of the polyps was also assessed using indocyanine green angiography. RESULTS A total of 77 patients were included in this study. Thirty-three eyes were treated with IVR, and 44 eyes were treated with PDT. Although no significant differences between the two groups were observed at baseline or at 3, 6, and 12 months after treatment, a significantly better BCVA was seen in the IVR group, compared with the PDT group, at 18 and 24 months after treatment (P=0.035 and P=0.021, respectively). No significant difference in the rate of polyp regression was observed between the two groups (P=0.092). CONCLUSION IVR was well tolerated and maintained or improved the vision of patients with PCV, compared with PDT, as evaluated at 2-year follow-up examinations. PDT for the treatment of PCV might result in unfavorable outcomes, with no superiority to achieving the involution of polyps.

Abstract
PURPOSE To compare the 2-year outcomes of photodynamic therapy (PDT) with or without intravitreal ranibizumab (IVR) for polypoidal choroidal vasculopathy (PCV). METHODS Medical charts from 58 patients with PCV, who had been followed up for more than 2 years after initial treatment, were reviewed retrospectively. Visual outcomes were compared between 2 groups, consisting of 34 patients treated with PDT monotherapy without IVR and 24 with the combination of PDT and IVR, and the factors associated with the 2-year visual outcomes were investigated using multiple regression analysis. RESULTS In the PDT monotherapy group, the logarithm of the minimum angle of resolution (logMAR) of the best-corrected visual acuity (BCVA) improved significantly at 12 months (P=0.026), but was not significantly different from the initial logMAR BCVA at 24 months (P=0.21). By contrast, the logMAR BCVA improved significantly at 12 months and was maintained throughout the second 12-month period (P<0.001 at all time points) in the combined PDT group. Multiple regression analysis revealed that the initial BCVA (P<0.001), the greatest linear dimension of the initial PDT (P=0.006), and the combined PDT (P=0.039) were predictors of visual outcomes at 24 months. CONCLUSIONS Combined PDT with IVR is a better treatment modality compared with PDT monotherapy, and results in improvement of visual outcomes at 24 months after the initial treatment.

Abstract
BACKGROUND Idiopathic polypoidal choroidal vasculopathy is an abnormal choroidal vascular pathology similar to age-related macular degeneration. It may present with sudden visual loss from hemorrhagic retinal pigment epithelial detachment and breakthrough vitreous hemorrhage or with chronic recurrent episodes. The condition is not uncommon in the retina clinic at the University College Hospital, Ibadan, Sub-Saharan Africa. This study presents the pattern of presentation in Ibadan. METHODS We review all cases of idiopathic polypoidal choroidal vasculopathy seen from 2007 to 2012 in the retina clinic at the University College Hospital, Ibadan, to determine the major pattern of presentations, available treatment modalities, and visual outcomes. RESULTS Ten cases were seen during the study period. Their mean age was 58 years, with a male to female ratio of 1:4. The most common presenting complaint was sudden visual loss. Major examination findings were retinal pigment epithelial detachment, orange subretinal lesions, and breakthrough vitreous hemorrhage. The modalities of treatment available included vitrectomy to clear vitreous hemorrhage. Intravitreal bevacizumab reduced the height of the pigment epithelial detachment and cleared vitreous hemorrhage. Thermal laser was applied for extrafoveal lesions. Two patients with subfoveal lesions were referred abroad for photodynamic therapy. Visual outcome showed significant improvement in vitrectomized patients who presented with vitreous hemorrhage. Presenting vision of hand motion and light perception improved to vision ranging from counting fingers to 6/12 after vitrectomy. CONCLUSION Idiopathic polypoidal choroidal vasculopathy may not be uncommon in Sub-Saharan Africa. A high index of suspicion is warranted in the diagnosis so as to provide timely intervention.

Abstract
PURPOSE To determine the optimal time for administration of intravitreal ranibizumab injections before photodynamic therapy (PDT) as combined therapy to treat polypoidal choroidal vasculopathy (PCV). DESIGN Retrospective, comparative, interventional case series. METHODS The study included 99 eyes (98 patients) with treatment-naïve subfoveal PCV treated with an intravitreal ranibizumab injection followed by PDT. The combination therapy included 1 ranibizumab injection administered 7 days before PDT (7-day group) or 2 days before PDT (2-day group). All eyes were followed for over 12 months. RESULTS Intravitreal ranibizumab was administered 7 days before PDT in 59 eyes and 2 days before PDT in 40 eyes. In the 7-day group, the best-corrected visual acuity (BCVA) did not improve significantly at 3 months (P = .086) or 12 months (P = .259) compared with baseline. In the 2-day group, BCVA improved significantly at 3 months (P < .001) and 12 months (P < .001). The polypoidal lesions regressed completely in 46 eyes (78.0%) in the 7-day group and in 34 eyes (85.0%) in the 2-day group; 38 eyes (64.4%) and 35 eyes (87.5%), respectively, did not require additional treatment, which differed significantly (P = .008) between the 2 groups. Subretinal hemorrhages did not develop in either group within 1 month after the combined therapy. CONCLUSIONS Administration of an intravitreal ranibizumab injection 2 days before PDT achieves significantly better visual outcomes and requires fewer additional treatments compared with administration of the injection 7 days before PDT.

Abstract
Purpose To describe the treatment outcome of photodynamic therapy (PDT) in Japanese patients with age-related macular degeneration (AMD) followed for 5 years. Patients and methods We retrospectively reviewed clinical charts of 51 patients with AMD. Thirty-one eyes of typical AMD (tAMD) and 20 eyes of polypoidal choroidal vasculopathy (PCV) were evaluated. Results The mean logarithm of the minimum angle of resolution (logMAR) vision of all AMD patients was 0.807 at the baseline examination and 0.937 at the 5 year examination. Mean visual acuity letter score loss is similar between patients with tAMD (−7.25) and with PCV (−5.36) at the month 60 examination. The patients with lesions of classic choroidal neovascularization (CNV) had 10.0 letters loss, but the patients with lesions of occult CNV had only 1.43 letters loss. The number of retreatments peaked in year 1 and declined immediately for patients with tAMD, but patients with PCV had significantly more frequent retreatments in the years 3 and 4 than patients with tAMD (P = 1.48 × 10−2, 5.96 × 10−3, respectively). Conclusion Visual outcomes in patients with Japanese patients with AMD treated with PDT after 5-year follow up were worse than that in short-term follow up reported previously. In addition, the difference in visual prognosis between tAMD and PCV was not demonstrated after long-term follow-up.

Abstract
PURPOSE To investigate the 2-year outcomes of three monthly intravitreal ranibizumab injections followed by as-needed reinjections to treat polypoidal choroidal vasculopathy (PCV). METHODS Seventy-five consecutive eyes with naïve symptomatic PCV with 2 years of follow-up after treatment were studied prospectively. RESULTS The mean (±SD) numbers of injections were 4.2±1.3 that included three monthly injections in the loading phase and 1.6±1.7 during years 1 and 2, respectively (mean 2-year total, 5.6±1.9). The baseline logarithm of the minimum angle of resolution visual acuity (VA) was 0.59±0.51 that improved significantly (p=0.001 for both comparisons) to 0.37±0.33 and 0.41±0.40 at 1 and 2 years, respectively, after the first injection. Although no significant difference was found between years 1 and 2 after the first injection, the VA tended to decrease slightly during year 2. The improved foveal thickness was maintained during year 2. Thirty (40%) eyes and 19 (25%) eyes, respectively, at years 1 and 2 after the first injection had no polypoidal lesions on indocyanine green angiography. A branching vascular network (BVN) remained in all eyes 2 years after the first injection and tended to increase in size during year 2. CONCLUSIONS The 2-year outcomes showed significant VA and foveal thickness improvements in eyes with PCV. During year 2, the magnitude of the improvement was lower compared with year 1. An as-needed reinjection schedule might not prevent polypoidal lesions or BVNs from regrowing. Further investigations should establish a treatment strategy for PCV.
