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
BACKGROUND Verteporfin photodynamic therapy (PDT) is approved for the treatment of predominantly classic subfoveal choroidal neovascularization (CNV) due to age-related macular degeneration (AMD), as well as for subfoveal CNV due to pathologic myopia and ocular histoplasmosis syndrome. Verteporfin PDT addresses the underlying pathology of ocular vascular disorders through its angio-occlusive mechanism of action, which reduces both visual acuity loss and the underlying leakage associated with lesions. Verteporfin PDT has also been associated with encouraging treatment outcomes in case studies involving patients with choroidal vascular disorders such as polypoidal choroidal vasculopathy, central serous chorioretinopathy, choroidal haemangioma, angioid streaks, and inflammatory CNV, i.e. conditions currently considered as non-standard indications of verteporfin PDT. In many studies, outcomes were better than expected based on the natural courses of each of these conditions. Although the anti-vascular endothelial growth factor (VEGF) therapies, ranibizumab and pegaptanib, have been approved for CNV due to AMD, their role in these other choroidal vascular disorders remains to be established. We summarize current literature that has documented the use of verteporfin PDT in these conditions. CONCLUSIONS The complex pathogenesis of CNV provides a rationale for investigating combination approaches comprising verteporfin PDT and anti-VEGF therapies. Randomized controlled studies are warranted to confirm the preliminary results of verteporfin PDT as a monotherapy or in combination with anti-VEGF therapies in the treatment of a variety of choroidal vascular conditions.

Abstract
BACKGROUND To investigate the prevalence and angiographic appearances of polypoidal choroidal vasculopathy (PCV) masquerading as age-related peripapillary subretinal neovascular membranes (PSRNVM). METHODS A consecutive case series of all patients investigated for presumed age-related PSRNVM in our tertiary referral centre over the period September 2006-2007. The presenting clinical features and fundus fluorescein angiographic (FFA) characteristics of each patient's lesion were identified. Any accompanying Indocyanine Green Angiogram (ICGA) was also reviewed, and on the basis of this investigation patients were classified into one of three groups: proven PCV, probable PCV and PSRNVM. RESULTS Thirty patients with presumed age-related PSRNVM were identified. The FFA leakage pattern was occult in 21 patients and classic in nine patients. Sixteen patients also had ICGA performed. In 14 of these patients the original FFA leakage pattern was occult, and in two it was classic. Of the 14 patients with occult leakage on FFA who subsequently underwent ICGA all were found to have PCV. CONCLUSIONS PCV is important and underrecognized in presumed age-related PSRNVMs. In such cases, particularly when the pattern of leakage on the fluorescein angiogram is occult, ICGA should be performed to identify the site of the polyps and if required to direct treatment.

Abstract
PURPOSE To describe a neovascular pattern associated with treatment-refractory neovascular age-related macular degeneration (AMD). DESIGN A retrospective observational case series. METHODS SETTING Clinical practice. PATIENT POPULATION Twelve eyes of 12 patients with neovascular AMD in which a poor anatomic response to anti-vascular endothelial growth factor (VEGF) therapy was related to polypoidal choroidal vasculopathy (PCV). OBSERVATION PROCEDURE Slit-lamp biomicroscopy, optical coherence tomography, fluorescein and indocyanine green angiography. MAIN OUTCOME MEASURES Snellen visual acuity (VA), anatomic response to therapy including presence or absence of retinal edema, hemorrhage, and lipid exudates. RESULTS New or persistent PCV was identified in a cohort of patients demonstrating increasing macular exudation despite regular intravitreal ranibizumab (Lucentis; Genentech Inc, South San Francisco, California, USA) or bevacizumab (Avastin; Genentech Inc) injections for a minimum of 6 months. Treatment with verteporfin photodynamic therapy (PDT), PDT/anti-VEGF combination therapy, or continued anti-VEGF monotherapy resulted in complete resolution of exudation in 9 of 12 patients and partial resolution of exudation in the remaining 3 patients. CONCLUSION Treatment-refractory neovascular AMD may harbor vascular abnormalities such as PCV. Modifications in therapeutic protocols may be indicated in order to improve visual and anatomic outcomes in this population.

Abstract
PURPOSE To investigate whether polymorphisms in 4 tightly linked genes of the major histocompatibility complex class III--complement component 2 (C2), complement factor B (CFB), RD RNA-binding protein (RDBP), and superkiller viralicidic activity 2-like (SKIV2L)--are associated with polypoidal choroidal vasculopathy (PCV). DESIGN Cross-sectional study. PARTICIPANTS A case-control group of 136 PCV subjects and 183 unrelated controls. METHODS We performed an association analysis between PCV and polymorphisms across the C2-CFB-RDBP-SKIV2L region in a Japanese population, genotyping 13 single nucleotide polymorphisms (SNPs) spanning this region, including rs9332739 (E318D), rs547154, rs4151667 (L9H), and rs641153 (R32Q) that are known to be associated with age-related macular degeneration (AMD). Genotyping was conducted using TaqMan technology (Applied Biosystems, Foster City, CA). We also examined population stratification in our study cohort. MAIN OUTCOME MEASURES Allele and haplotype frequencies of the variants across the C2-CFB-RDBP-SKIV2L region. RESULTS We initially scanned the C2-CFB locus using 11 SNPs that capture the majority of common variations in this locus. We found a significant omnibus haplotype association and a single disease-protective haplotype, but individually, none of the 11 SNPs were associated with PCV. Further studies led to the identification of 2 untested allelic variants in RDBP (rs3880457) and SKIV2L (rs2075702) that were located on the protective haplotype. We also analyzed these 2 SNPs, detecting a significant association with a decreased risk of developing PCV (for both SNPs, allelic P = 0.0038 and per allele odds ratio = 0.31 [95% confidence interval, 0.13-0.71]). The 2 SNPs were correlated (r(2) = 1) in our dataset. Haplotype analysis and conditional testing demonstrated that either rs3880457 or rs2075702 could fully account for the omnibus haplotype association detected across the C2-CFB-RDBP-SKIV2L region. Population stratification analyses excluded stratification artifacts in our study cohort. CONCLUSIONS Our results do not support any major role of the 4 AMD-associated variants in the risk of developing PCV, but favor a predominant association with the RDBP-SKIV2L variants, which has some potential implications for pathobiological differences between PCV and neovascular AMD. Further genetic characterization of this locus will provide additional insights into the genetic basis of PCV susceptibility.

Abstract
OBJECTIVES To clarify the clinical and angiographic characteristics of idiopathic polypoidal choroidal vasculopathy (IPCV) and its natural course. METHODS Descriptive, prospective, consecutive case series of patients with presumed IPCV seen at Fort-de-France Hospital Center (French West Indies) between January and June 2006. All participants underwent complete eye examination and fluorescein and indocyanine green (ICG) angiography. The nature and location of the lesions were assessed in all eyes. Inclusion criteria were demonstration of characteristic lesions of IPCV on ICG angiography. RESULTS Diagnosis of IPCV was made in 26 eyes of 14 patients, ten women and four men, all of Afro-Caribbean origin. The mean age was 77.4 years (range 60-92 years). Drusen were present in 13 eyes (50%), age-related macular degeneration (AMD) in one eye, and branch retinal vein occlusion in one eye. Twelve patients (85.7%) had bilateral involvement. Twelve eyes (46.2%) had visual acuity (VA) (Snellen) worse than 20/200, six eyes (23.1%) had VA between 20/200 and 20/100, and eight eyes (30.8%) had VA better than 20/100. On ICG angiography, lesions were predominantly located in the peripapillary area but also in the midperiphery, the macular and interpapillomacular areas, and the far periphery. CONCLUSION Peripheral locations of IPCV and associations with drusen or AMD are not rare. The prognosis of the disease is poor in its natural course. Its etiology is unknown but genetic factors are probably involved. It is the main differential diagnosis for exudative AMD in black patients.

Coding variant I62V in the complement factor H gene is strongly associated with polypoidal choroidal vasculopathy. Ophthalmology 2009; 116:304-10.

Abstract
PURPOSE To investigate whether variants in the complement factor H (CFH) gene are associated with polypoidal choroidal vasculopathy (PCV). DESIGN Cross-sectional study. PARTICIPANTS A case-control group of 130 PCV subjects and 173 unrelated controls. METHODS We conducted an association analysis between CFH variants and PCV in a Japanese population, genotyping 12 tag single nucleotide polymorphisms (SNPs)-including rs3753394, rs800292 (I62V), and rs1061170 (Y402H)-that are highly representative of the common genetic variation in the CFH region. Genotyping was performed using TaqMan technology. MAIN OUTCOME MEASURES Allele and haplotype frequencies of the CFH variants. RESULTS A highly significant association with PCV was observed across the CFH region. The strongest association was observed at I62V (P = 1.7 x 10(-7)). Six other SNPs (rs3753394, rs6680396, rs1410996, rs2284664, rs1329428, and rs1065489) also showed significant association (10(-3) < P < 10(-6)). These associations became nonsignificant after accounting for rs800292 in a conditional logistic regression analysis. A significant omnibus haplotype association was detected in the entire CFH region (omnibus P = 1.6 x 10(-5) at 7 degrees of freedom). Conditional haplotype-based likelihood ratio tests revealed that the significant omnibus haplotype association disappeared when it was estimated conditional on I62V (omnibus P = 0.20, 6 degrees of freedom, post-I62V dependency), whereas the omnibus haplotype association remained significant when it was estimated conditional on any SNP other than I62V. These findings indicate that multiple observed effects were caused by linkage disequilibrium with I62V, and that this variant fully accounts for the association signals observed at the set of SNPs examined at this locus. CONCLUSIONS The present study provides evidence that the complement pathway plays a substantial role in the pathogenesis of PCV. The nonsynonymous variant I62V is a plausible candidate for a causal polymorphism leading to the development of PCV, given its potential for functional consequences on the CFH protein and our own statistical evidence.

Abstract
BACKGROUND Exudative age-related macular degeneration (AMD) is a sight-threatening event in many elderly people. Some patients have a much better outcome in visual acuity (VA) than others after treatment with photodynamic therapy (PDT) with verteporfin. The combination of fluorescein angiography (FA) and indocyanine green (ICG) angiography using the Heidelberg Retina Angiograph II (HRA 2) should make a delineation of distinct pattern(s) possible in order to better select and assess therapy. METHODS This is a retrospective, case-control, single-centre study. We identified a total of 168 eyes of 168 patients from July 2003 to June 2006, including 30 eyes of 30 patients with better visual outcome, defined in this study as VA < or = 0.48 logMAR (> or =20/60 Snellen chart) at the end of the study. Best-corrected VA, maximal central retinal thickness as measured by optical coherence tomography, and results of the FA/ICG angiography using the HRA 2 were analyzed. In this article, we discuss patients with polypoidal choroidal vasculopathy (PCV) and their characteristics. RESULTS The average follow-up time was 15.3 months (range 4-28 months). Seventeen (57%) of the 30 patients with better visual outcome had PCV. All patients in the group with better visual outcome needed fewer PDT treatments compared with our control group of patients with an exudative AMD. INTERPRETATION Simultaneous FA/ICG angiography using the HRA 2 allowed delineation of a subgroup of patients with PCV who showed a better visual outcome compared with those with other types of exudative AMD, after treatment with PDT.

Abstract
Purpose To evaluate the efficacy and safety of intravitreal bevacizumab for polypoidal choroidal vasculopathy (PCV). Methods In this retrospective interventional pilot study, 12 eyes of 11 patients with active PCV were treated with intravitreal bevacizumab (1.25 mg) alone or in combination with photodynamic therapy (PDT) depending on the informed patient's choice. Intravitreal bevacizumab was repeated at 6-week intervals until the regression of active lesion was detected on fluorescein angiography (FA) which was done on a regular basis, Indocyanine green angiography (ICGA) and optical coherence tomography (OCT) analyses. Results Intravitreal bevacizumab was given alone in 8 eyes (Group 1) and in combination with PDT in 4 eyes (Group 2). Mean follow-up duration was 17 weeks in group 1 and 15 weeks in group 2 after bevacizumab treatment. The mean number of bevacizumab injections was 2.2 in group 1 and 2.5 in group 2. Mean BCVA improved from 20/63 to 20/40 in group 1 and 20/63 to 20/32 in group 2. Of all eyes, the BCVA improved by ≥2 lines in seven (58%) eyes and resolution of fluid and hemorrhages in clinical examination, an absence of leakage on repeat FAs, or resolved pigment epithelial detachment (PED) and/or subretinal fluid (SRF) on OCT exam was confirmed in 10 (83%) eyes. Partial or complete regression of the polypoidal vessels and interconnecting vessels was reported for most cases at the last follow-up. No significant ocular or systemic side effects were observed in both groups. Conclusions Short-term results indicate that intravitreal bevacizumab (1.25 mg) alone or in combination with PDT is well tolerated and associated with improvement in BCVA and reduced angiographic leakage in most patients. Further evaluation of intravitreal bevacizumab therapy for the treatment of PCV is warranted.

Abstract
PURPOSE Description of the clinical and angiographic manifestations of polypoidal choroidal vasculopathy (PCV) in two brothers of West Indian origin. METHOD Case reports. RESULTS In Case 1 (82-year-old), the disease presented when the patient was 50 years old with decreased visual acuity in the right eye. Onset of symptoms in the left eye occurred 30 years later. Visual acuity was limited to good luminous orientation in both eyes. In Case 2 (78-year-old), the disease presented in the right eye when the patient was about 68 years old. Visual acuity in the right eye was reduced to good luminous orientation. Symptoms in the left eye appeared 10 years later. Visual acuity in the left eye was 20/100. In both patients, medical history was significant only for arterial hypertension. There was no intraocular inflammation or ocular hypertonicity. Indocyanine green angiography revealed hyperfluorescent polypoidal dilatations at early and intermediate phases, characteristic of PCV. CONCLUSION These observations argue in favor of a genetic component in PCV.

Abstract
PURPOSE To study the prevalence and clinical features of drusen in eyes with polypoidal choroidal vasculopathy (PCV). METHODS Retrospectively, we reviewed the records of 98 consecutive patients with PCV (102 eyes). Drusen were examined in the inner macula, which was defined as an area within 1500 microm of the center of the fovea. Eyes that had at least one intermediate or large (>or=63 microm) soft drusen within the inner macula were defined as having drusen. RESULTS In these 102 eyes with PCV, 23 (23%) showed soft drusen in the inner macula. In such cases, the fellow eyes, those without a PCV lesion, sometimes also showed soft drusen in the inner macula (11 eyes); 34 (33%) of the eyes with PCV had soft drusen in the inner macula of at least one eye. Comparison of the group of eyes with PCV and drusen in one or both eyes with the group with PCV and no drusen in either eye revealed no significant difference in patient characteristics or in ocular manifestations. CONCLUSIONS Drusen are not an unusual feature of PCV, at least in Japanese patients, and, when present, they appear to have only a minor effect, if any, on the clinical course.

Abstract
PURPOSE To determine the incidence, demographic features, and clinical characteristics of polypoidal choroidal vasculopathy (PCV) in Korean patients. METHODS A retrospective review was undertaken of 392 eyes of 321 symptomatic patients suspected of having exudative age-related macular degeneration (AMD) after their first visit to a tertiary hospital between February 2002 and May 2006. All patients underwent a complete ophthalmic examination, including fluorescein and indocyanine green angiography (ICGA). RESULTS Of the 321 patients (392 eyes), 79 (98 eyes, 24.6%) were diagnosed with PCV. The mean PCV patient age was 64.6 +/- 7.6 years. PCV was more common in men (78.5%), and was usually unilateral (75.9%). In terms of PCV clinical manifestation, 52% of patients showed an exudative pattern, 34.7%, a hemorrhagic pattern, and 13.3%, an extensive hemorrhagic pattern. The mean visual acuity at presentation was 0.231 +/- 0.256. Classification was based on ICGA findings; 52% of patients showed relatively large aneurismal dilations, 25.5% showed atypical vessel deformations, and 22.5% showed dense clusters of numerous small hyperfluorescent dots. CONCLUSIONS The incidence of PCV in Korean exudative AMD patients was relatively high compared with that in other ethnic groups. As in other Asian patient populations, PCV occurred more commonly in men and was predominantly unilateral.

Abstract
BACKGROUND A choroidal osteoma is a benign osseous tumor typically arising in the juxtapapillary or peripapillary area. The major cause of visual loss is secondary to the development of a subretinal neovascular membrane. The pattern of neovascularization that develops with osteomas has been typically described as classic choroidal neovascularization (CNV). METHODS Interventional case report. RESULTS A case of bilateral polypoidal choroidal neovascularization (PCV) occurring with bilateral choroidal osteomas is described in a 55-year-old Japanese woman. To our knowledge, this variant form of vasogenesis has not previously been described in association with this tumor. Clinical, angiographic, and optical coherence tomographic features are discussed. Subretinal hemorrhage in the left eye from polypoidal neovascularization in the macula was successfully treated with photodynamic therapy. CONCLUSIONS The association between choroidal osteoma and PCV may have a better prognosis than that with classic CNV. Indocyanine green angiography is a useful tool in characterizing the nature of the neovascularization.

Abstract
PURPOSE To assess the contribution of indocyanine green angiography (ICGA) to fluorescein angiography (FA) in evaluating fellow drusen eyes of patients with wet age-related macular degeneration (AMD) in the other eye. METHODS The records of paired FA and ICGA of patients with dry AMD in one eye and wet AMD in the other eye were retrospectively reviewed. Based on color fundus photographs, drusen were graded to low, moderate, or high grade of severity on FA. The FA and ICGA findings were compared. RESULTS Fifty-two pairs of eyes were included. Fluorescein angiography showed drusen of low severity in 11 (21.2%) eyes, of moderate severity in 31 (59.6%), and of high severity in 10 (19.2%). Leakage on both FA and ICGA was not demonstrated in any case of drusen of low or moderate severity. Only in 2 out of 10 eyes from the high severity group, 3.8% of the eyes of the whole study population, did ICGA reveal occult choroidal neovascularization (CNV) that was not observed on FA. CONCLUSIONS In selected eyes with drusen of high grade severity, ICGA may detect occult CNV, unrecognized clinically or by FA. ICGA had a small contribution to the diagnosis of occult CNV in fellow drusen eyes with any degree of severity.

Abstract
PURPOSE To investigate whether variants in the LOC387715 locus and the HtrA serine peptidase 1 (HTRA1) gene within the 10q26 locus are associated with polypoidal choroidal vasculopathy (PCV) and wet age-related macular degeneration (AMD) in a Japanese population, and whether genetic diversity exists between PCV and wet AMD in this locus. DESIGN Cross-sectional study. METHODS We genotyped 243 Japanese individuals, including 76 PCV cases, 73 wet AMD cases, and 94 controls using two single nucleotide polymorphisms (SNPs) that are located in the LOC387715 locus (rs10490924) or the HTRA1 gene (rs11200638). Genotyping was performed using TaqMan assays (Applied Biosystems, Foster City, California, USA). RESULTS Two SNPs generated highly significant allelic associations with PCV (rs10490924, P = 5.7 x 10(-6); rs11200638, P = 5.2 x 10(-6)) and AMD (rs10490924, P = 1.4 x 10(-6); rs11200638, P = 3.4 x 10(-7)). The odds ratios and population attributable risks were higher for the AMD cases than for the PCV cases. Homozygotes for the risk allele at rs11200638 had a 6.33-fold increased risk of PCV and a 13.77-fold increased risk of wet AMD when compared with homozygotes for the wild-type allele. There were no significant differences in either allelic or genotypic frequencies between PCV and AMD cases. CONCLUSIONS The LOC387715/HTRA1 variants are associated with PCV and wet AMD in the Japanese population. The associations are stronger in AMD than in PCV. PCV and AMD share common genetic factors, which suggests that PCV and wet AMD are similar in some pathophysiologic aspects.

Abstract
BACKGROUND To study the morphologic features of polypoidal choroidal vasculopathy (PCV) with the use of en face optical coherence tomography (OCT). METHODS We reviewed retrospectively 57 eyes of 57 patients with PCV. The macular region was examined with OCT en face planes scanned at different sequential depths, following which detailed scanning was performed of arbitrarily selected longitudinal planes. RESULTS In 48 of the cases (84.2%), en face OCT allowed us to detect round protrusions of the retinal pigment epithelium (RPE) that corresponded to the polypoidal lesions seen on indocyanine green angiography (ICGA); the branching vascular networks seen on ICGA often induced slight elevation of the overlying RPE, which typically assumed a geographical shape. In 30 cases (52.6%), branching vascular networks were detected as elevations of the RPE. With en face OCT, serous pigment epithelial detachments, most of which were seen as round protrusions of the RPE, were often accompanied by adjacent smaller round protrusions of the RPE, consistent with polypoidal lesions. These protrusions of the RPE were often fused and typically appeared as a 'snowman'. Subsequent longitudinal examination revealed the polypoidal lesions to be sharp protrusions of the RPE with moderate inner reflectivity. Consistent with the location of the branching vascular network, a highly reflective line was seen often just beneath the slightly elevated reflective line of RPE. CONCLUSIONS En face examination using OCT has an advantage in screening lesions of PCV and in examination of the detailed relationship of each component of these lesions.

Abstract
PURPOSE To evaluate the efficacy of selective treatment with indocyanine green (ICG) angiography-guided photodynamic therapy (PDT) with verteporfin for polypoidal choroidal vasculopathy (PCV). METHODS In this retrospective consecutive series, 30 eyes of 30 patients with PCV were included. Complete ocular examination, digital fluorescein angiography (FA), ICG angiography, and optical coherence tomography were performed at baseline and at standard intervals thereafter. ICG angiography-guided PDT was performed on all eyes. Only the area of the active PCV or "hot spot" evident on the ICG angiogram was treated. A spot size was chosen to cover the active neovascular lesion with a 200-mum border. Retreatment was performed when angiography revealed a recurrent lesion. RESULTS Thirty eyes with PCV were treated and followed for 1 year. Mean age of the patients was 75 years (range, 55-90 years). These patients were all classified as having occult choroidal neovascularization (CNV) with FA and polypoidal CNV with ICG angiography. Improvement of vision (>or=3 lines) was achieved in 15 eyes (50%). Nine eyes had stable vision (30%), and 6 eyes (20%) had a decrease in vision (>or=3 lines). Repeated treatment was required in 15 eyes (50%) for an average of 2.2 treatments in 1 year. CONCLUSION This study indicates that stabilization or improvement of vision is achieved in most eyes (80%) with neovascular AMD from PCV after selected ICG angiography-guided PDT. These outcomes compare very favorably with those in previous reports on the treatment of occult CNV. Reduced collateral damage to the choriocapillaris and reduced upregulation of vascular endothelial growth factor are presumed to be the explanation for this apparently better outcome. Further studies with longer follow-up are warranted to investigate the long-term efficacy in these conditions.

Abstract
PURPOSE To determine the relationship between systemic C-reactive protein (CRP) levels and polypoidal choroidal vasculopathy (PCV) and advanced neovascular age-related macular degeneration (AMD) in Japanese patients. DESIGN Case-control study. PARTICIPANTS Ninety-seven patients with PCV, 176 with advanced neovascular AMD, and 262 control subjects without any macular abnormality were studied. METHODS Color fundus photographs of the macular area were taken from both eyes in all subjects. Indocyanine green angiography and fluorescein angiography were performed for diagnosis. The CRP level was measured by a high-sensitivity assay using a latex aggregation immunoassay, and the levels in patients with PCV and neovascular AMD were compared with that in the control group using the Kruskal-Wallis test. Associations between CRP and PCV or neovascular AMD were compared using logistic regression analysis by computing the odds ratios (ORs) and 95% confidence intervals (CIs) after the study populations were divided into quartiles. MAIN OUTCOME MEASURES The CRP levels in patients with PCV, patients with neovascular AMD, and control subjects. Standard univariate and multivariate analyses between groups. RESULTS Median CRP levels were significantly higher in cases with PCV (0.94 mg/l) or with advanced neovascular AMD (0.95 mg/l) than in control subjects (0.43 mg/l) (P<0.001 for Kruskal-Wallis test). After adjusting for baseline characteristics such as age, gender, smoking status, alcohol use, body mass index, history, and use of antiinflammatory drugs, the increase in risk was significant for the highest quartile of CRP for both PCV (OR, 3.53; 95% CI, 1.49-8.40) and neovascular AMD (OR, 4.08; 95% CI, 1.94-8.56), and for the third quartile of CRP for neovascular AMD (OR, 2.29; 95% CI, 1.07-4.91). The trends for an increase in risk of disease with increase in CRP were statistically significant for both PCV (P = 0.001) and neovascular AMD (P<0.001). CONCLUSIONS The significant associations between elevated serum CRP levels and PCV or neovascular AMD in the Japanese strongly suggest that inflammatory processes are involved in the pathogenesis of PCV and neovascular AMD.

Abstract
PURPOSE To report the 12-month follow-up results of subfoveal polypoidal choroidal vasculopathy (PCV) patients treated with indocyanine green angiography (ICGA)-guided photodynamic therapy (PDT). DESIGN Interventional, noncomparative cases series. METHODS A retrospective analysis of the clinical and angiographic data related to 47 PCV eyes that were followed up for 12 months was carried out. The greatest linear dimension (GLD) for PDT was determined based on the ICGA findings. Optical coherence tomography (OCT) also was used to evaluate the therapeutic effects. RESULTS The mean logarithm of the minimum angle of resolution visual acuity (VA; 0.58 +/- 0.37) significantly improved to 0.53 +/- 0.38 at three months (P = .04) and to 0.46 +/- 0.40 at 12 months (P = .02). The average ICGA GLD (2682.3 +/- 1026.9 mm) was significantly (P = .0001) smaller than the presumed fluorescein angiography (FA) GLD (4043.6 +/- 1914.8 mm). In more than 80% of cases, complete resolution of retinal exudative changes was observed. Although polypoidal vascular lesions disappeared in 82.2% of eyes, the branched vascular networks showed little change. The initial VA and GLD had little correlation with the VA outcome. CONCLUSIONS ICGA-guided PDT reduces the size of laser exposure and is an effective treatment for PCV. Because PCV may appear as occult choroidal neovascularization (CNV) on FA, PCV should be diagnosed using ICGA before treatment because PCV may respond differently than CNV to appropriate treatment.

Abstract
PURPOSE To report two cases that had polypoidal choroidal vasculopathy (PCV) coexisting with choroidal neovascularization (CNV) of exudative age-related macular degeneration (AMD). METHODS Both of the patients underwent color photographs, fluorescein and indocyanine green (ICG) angiography. RESULTS On fundus examination, a grayish lesion in the foveal area, reddish-orange lesions and hemorrhagic retinal pigment epithelial detachments (PED) in the inferotemporal vascular arch were disclosed in the left eye of a patient, and macular scarring was observed in the fellow eye. ICG angiography revealed a typical branching vascular network and polyp-like aneurysmal dilations at terminals of branches in the inferotemporal vascular arcade and a well-demarcated hyperfluorescent area of CNV in the fovea in the left eye, and staining of macular scarring was present in the fellow eye. On fundus examination of the right eye of the other patient a gray-yellow lesion at the fovea, reddish-orange lesions in the extramacula were noted, and diffuse drusens were present in the fellow eye. ICG angiography revealed scattered polyp-like aneurysmal dilations without identifiable continuous branching vascular network in the extramacula, and a well-demarcated hyperfluorescence area of CNV in the fovea. CONCLUSIONS PCV can coexist with exudative AMD in some patients and the polypoidal lesions may less involve in the fovea than CNV. Evidence of AMD are present meanwhile in the fellow eyes these patients.

Abstract
PURPOSE To determine the prevalence of polypoidal choroidal vasculopathy (PCV) in Japanese patients presumed to have age-related macular degeneration (AMD) and compare 1-year outcomes after photodynamic therapy between PCV and choroidal neovascularization secondary to AMD. DESIGN Prospective interventional study. PARTICIPANTS Ninety-three consecutive patients (93 eyes) met the inclusion criteria: at least 50 years old, best-corrected visual acuity (VA) of 34 to 73 on the Early Treatment Diabetic Retinopathy Study (ETDRS) letter chart, a subfoveal lesion 5400 mum or smaller in greatest linear dimension (GLD) on fluorescein angiography (FA), and eligibility for photodynamic therapy. METHODS Indocyanine green angiography was performed in all participants, and PCV and AMD were differentiated, treated with photodynamic therapy, and the patients observed for 1 year. The GLD was determined by FA for AMD and by indocyanine green angiography for PCV, and the diameter of the laser spot size was chosen, with an extra 1000 microm added to the GLD. Photodynamic therapy was repeated if leakage occurred on FA at 3-month follow-up visits. MAIN OUTCOME MEASURES Prevalence of PCV at baseline and visual and angiographic changes 1 year after photodynamic therapy in PCV and AMD. RESULTS Using indocyanine green angiography, 36 eyes (39%) were diagnosed with PCV and 54 eyes (58%) with choroidal neovascularization secondary to AMD. The median change in VA using the ETDRS letter score from baseline to 1 year was -7.0 in AMD eyes and +8.0 in PCV eyes (Mann-Whitney rank sum test; P<0.001). The VA improved (> or =15 letters) in AMD and PCV by 6% and 25%, respectively, and decreased (> or =15 letters) by 31% and 8%, respectively. Fluorescein leakage stopped at 1 year in 86% of PCV and 61% of AMD eyes (P = 0.031). Polypoidal choroidal vasculopathy recurred in 2 PCV eyes (5.6%), and a new PCV lesion developed in 1 PCV eye (2.8%) and 2 AMD eyes (3.7%) on indocyanine green angiography at 1 year. CONCLUSION The prevalence of PCV meeting the treatment criteria for photodynamic therapy for presumed AMD is high in Japanese patients. Photodynamic therapy is more efficacious for PCV than for AMD, which may explain the good results in Japanese patients. Further study should assess the long-term clinical results.

Abstract
PURPOSE To evaluate the effects of photodynamic therapy (PDT) with verteporfin 1 year after treatment in Japanese patients with age-related macular degeneration (AMD) and subfoveal choroidal neovascularization. METHODS Between May 2004 and March 2005, PDT was performed on 102 eyes of 98 patients (60 men and 38 women) with AMD and subfoveal choroidal neovascularization. Patients were followed for at least 12 months after PDT. RESULTS The mean visual acuities in logarithm of the minimum angle of resolution (logMAR) units were 0.978 at baseline, 0.919 at 3 months, 0.895 at 6 months, 0.892 at 9 months, and 0.874 at 12 months. After PDT, the logMAR visual acuity improved by >0.3 logMAR units or more in 28 eyes (27%) and deteriorated by >0.3 logMAR units or more in 13 eyes (13%). Stable or improved vision was achieved in 93% of patients with polypoidal choroidal vasculopathy (PCV). CONCLUSIONS The visual outcome in our patients was similar to that of an earlier major Japanese study, and similar to or better than outcomes in Western studies. Differences between Caucasians and Japanese might influence the characteristics of PCV. It is possible that PDT is more effective for AMD patients with PCV than for other AMD patients. Further observations and longer follow-up are necessary.

Microperimetry in the macular area was performed with Micro Perimeter 1 (MP1) [Nidek, Vigonza, Italy] before and at one, three, and six months after PDT. Forty measurement points were located within the central 10 degree of the macula. RESULTS After PDT, although most eyes showed a reduction in exudation, the mean posttreatment visual acuity did not change significantly. At one month after PDT, however, retinal sensitivities within the central 2 degree, 6 degree, and 10 degree fields, which were 3.6 +/- 3.1, 5.1 +/- 3.4, and 6.2 +/- 3.6 dB [decibels] at baseline, improved to 5.9 +/- 3.8 (P = .003), 7.1 +/- 3.6 (P = .003), and 8.1 +/- 3.5 dB (P = .004). At one month after treatment, 14 patients (70%) noted subjective improvement of the central visual disturbance and mean retinal sensitivity within the central 2 degree, 6 degree, and 10 degree fields had improved more than 2 dB in 11, 10, and eight eyes, respectively. At three and six months after PDT, however, postoperative improvement of the retinal sensitivities was diminished. CONCLUSIONS Retinal sensitivity in the macular area of eyes with subfoveal PCV improved shortly after PDT, and may account, at least in part, for the immediate subjective improvement in central vision after PDT.

Abstract
PURPOSE To determine and compare the clinical characteristics, visual prognosis and treatment of hemorrhagic polypoidal choroidal vasculopathy (HPCV) with those of hemorrhagic choroidal neovascularization (HCNV) due to age-related macular degeneration (ARMD). MATERIALS AND METHODS Retrospective analysis of 44 consecutive eyes with a submacular hemorrhage comprising more than 50% of the neovascular lesion. Patients were diagnosed as having HPCV or HCNV on the basis of indocyanine green angiography. RESULTS Of the 44 eyes with submacular hemorrhage, 26 were classified as HPCV and 18 as HCNV. The baseline patient characteristics were similar for both groups. At the final follow-up the HPCV group had 17 eyes showing visual improvement, four showing maintained vision, and five showing visual deterioration. In contrast, the HCNV group had four eyes showing visual improvement, one showing maintained vision, and 13 showing visual deterioration. Visual acuity of < 0.1 at follow-up was found in 7 (27%) of HPCV eyes and 10 (56%) of HCNV eyes. PDT was performed in 15 HPCV eyes, of which 13 (87%) showed improvement or no change in visual acuity, while only 2 (22%) of the 9 HCNV eyes responded similarly after PDT. Eyes treated with PDT did not have better outcomes compared to eyes that underwent other types of treatment (Fisher's exact test, p > 0.05). CONCLUSION PCV accounts for the largest proportion of submacular hemorrhage in Koreans. PCV showed a better visual prognosis than CNV.

Abstract
PURPOSE To identify the subtype frequency and clinical features of neovascular age-related macular degeneration (AMD) in Chinese patients. METHODS From January 2003 to August 2006, we investigated prospectively 155 newly diagnosed patients with presumed neovascular AMD. Fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in both eyes of all patients. Subtype frequency and clinical features were recorded according to their angiograms. RESULTS Three subtypes of lesion were noted, which were polypoidal choroidal vasculopathy (PCV), retinal angiomatous proliferation (RAP) and mixed lesions. Of the 155 patients, 105 (67.7%) had choroidal neovascularization (CNV) of the typical type seen in AMD, 38 (24.5%) had PCV and seven (4.5%) had RAP. In five (3.2%) additional cases, mixed lesions were noted. In 38 cases (47 eyes) with PCV, the rates of subfoveal, juxtafoveal and extrafoveal lesion were respectively 29.8% (14 eyes), 8.5% (four eyes), and 61.7% (29 eyes), compared with 75.6%, 14.6% and 9.8% for CNV lesion (P < 0.01). The percentage of subfoveal lesion in PCV group was significantly lower than that in the CNV group (P < 0.01). The location of the RAP lesion was subfoveal in two (28.6%) eyes, juxtafoveal in three (42.9%) eyes and extrafoveal in two (28.6%) eyes. The five eyes with mixed lesions were all PCV coexisting with CNV at the same eye, and in all of the five cases, CNV was subfoveal while PCV was extrafoveal. CONCLUSIONS In this hospital-based study, PCV accounts for 24.5% of neovascular AMD and is the most common subtype, RAP is less frequent (4.5%), and mixed lesions are much less common in Chinese patients. PCV is least likely to involve the fovea in neovascular AMD.

Graefes Arch Clin Exp Ophthalmol 2007; 245:1421-7. [PMID: 17347808 DOI: 10.1007/s00417-007-0564-y] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2006] [Revised: 01/09/2007] [Accepted: 02/17/2007] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Before treating polypoidal choroidal vasculopathy (PCV), the extent of the lesion should be determined, but the angiographic lesion size of PCV is sometimes different when comparing indocyanine green angiography (ICGA) and fluorescein angiography (FA). The purpose of this study was to evaluate angiographic findings and compare the lesion sizes of PCV on ICGA and FA using confocal scanning laser ophthalmoscopy (SLO) and fundus camera. METHODS Thirty-seven eyes of 37 patients with PCV were examined by ICGA and FA using confocal SLO and a fundus camera, and the findings and the lesion sizes were compared during the early, mid, and late-phases of ICGA and FA. RESULTS The polyps with abnormal vessel networks were depicted on ICGA in all eyes and the lesion showed classic-type leakage on FA in 15 eyes. Ten eyes with a pigment epithelial detachment (PED) had the maximal lesion size on FA because hyperfluorescent areas involving PED were determined as the lesions; although on ICGA, a PED distinguished from abnormal vessels was not included in the lesion. In 27 eyes without a PED, the early-phase of ICGA using confocal SLO showed the maximal lesion size in 24 eyes (89%) and the late-phase in three eyes (11%), and the maximal size on ICGA agreed on FA. While FA depicted the maximal lesion sizes in 24 eyes (89%), another three eyes showed the maximal lesion size on early-phase ICGA on confocal SLO. The maximal lesion size on ICGA using a fundus camera was smaller than when using confocal SLO in seven eyes (19%). CONCLUSIONS The ICGA on confocal SLO could visualize the more detailed findings of the abnormal vasculature of PCV and the FA showed hyperfluorescent regions overlaying the lesions. To determine the maximal lesion size on angiograms, early-phase ICGA using confocal SLO and FA should be referred.

Abstract
AIMS To study the visual prognosis and ocular characteristics of eyes with polypoidal choroidal vasculopathy (PCV) that appear to have classic choroidal neovascularisation (CNV) on fluorescein angiography (FA). METHODS The authors reviewed retrospectively 38 eyes with PCV that appear to have classic CNV on FA. Lesions were examined with indocyanine green angiography, FA and optical coherence tomography (OCT). RESULTS In all cases OCT showed subretinal material with moderate reflectivity that corresponded in location to classic CNV. At the final visit, the subretinal material resolved completely in 14 eyes (36.8%, resolved group), but resolved only incompletely in 24 eyes (63.2%, persisted group) after photodynamic therapy (PDT). Mean (standard deviation) visual acuity in the resolved group (0.35 (0.41) in log MAR) was significantly better than that in the persisted group (0.84 (0.24)) at the final visit (p<0.001). The subretinal material seen before treatment was more frequently seen in subfovea in the persisted group (87.5% vs 42.9%, p = 0.007). Also, this material was located adjacent to polypoidal lesions more often in the resolved group (92.9% vs 58.3%, p = 0.030). CONCLUSIONS Eyes with PCV sometimes show classic CNV with subretinal material apparent on OCT, and PCV is thus attributed to type 2 CNV or to pure fibrinous tissue without CNV. Visual prognosis in eyes with type 2 CNV is poor, and although it is difficult to discriminate type 2 CNV from pure fibrin deposition before treatment, type 2 CNV is seen more often in the subfovea and is typically separate from the polypoidal lesions.

Abstract
PURPOSE To determine the safety and efficacy of photodynamic therapy with verteporfin (V-PDT) in the treatment of exudative idiopathic polypoidal choroidal vasculopathy (IPCV) lesions that were not suitable for laser photocoagulation. METHODS This was a prospective, open label study in two centers involving 30 consecutive patients (31 eyes) diagnosed with exudative IPCV using fluorescein angiography (FA), indocyanine green angiography (ICGA), and optical coherence tomography (OCT). All patients underwent complete ophthalmologic examination including best-corrected visual acuity (VA) measurement, contrast sensitivity (CS) testing, FA, ICGA, and OCT. OCT was used to assess the stage of the polypoidal dilations (active or scarred) and the evolution of the signs associated with exudation. Study patients were treated with V-PDT and followed up at 6 weeks and 3, 6, and 12 months. Re-treatment was applied, at an interval of 3 months, until there was an absence of leakage on FA and hyperfluorescence on ICGA. RESULTS Thirty eyes (29 patients) completed the 12 months post-treatment visit and were retained for further analysis. The mean number of V-PDT treatments was 2.5 (SD 1.1). At 12 months post-treatment, the mean foveal thickness had significantly (p<0.03) decreased to 224 (SD 104) microm from the baseline 292 (SD 124) microm while the mean VA had significantly (p<0.02) improved to 0.50 (SD O.38) from the baseline 0.38 (SD 0.24). Serous detachment of the macula completely resolved in 83.3% of the eyes while 73.3% of the polypoidal dilations were occluded at 12 months. CONCLUSIONS The results suggest that V-PDT is effective and relatively safe in treating exudative IPCV.

Abstract
PURPOSE The ocular histopathologic features of a patient with bilateral multiple midperipheral areas of choroidal vascularization, large drusen, and detachments of the retinal pigment epithelium (RPE) are presented. METHODS The eyes were obtained at autopsy and fixed in 4% buffered formaldehyde. Serial sections through the macula area and inferior segments were prepared. Light as well as electron microscopy was performed. RESULTS Microscopic examination disclosed numerous large drusen measuring up to 200 micro m in height and 280 micro m in diameter and areas of serous RPE detachments in the midperiphery of both eyes. Some of the large drusen had choroidal vascularization. Areas of sub-RPE neovascularization that measured up to 6.5 mm in diameter were present in the midperiphery of both eyes. The choroidal origin for neovascularization was evident in 10 areas. A 1-mm area of hemorrhagic detachment of the RPE contiguous with choroidal neovascularization (CNV) was present in the immediate postequatorial area temporally in the left eye. No drusen, basal deposit, or CNV was present in the macular area. CONCLUSION Multifocal midperipheral RPE detachments and CNV can occur in the absence of significant age-related macular disease.

Abstract
PURPOSE To study the morphological features of serosanguineous pigment epithelial detachments (PEDs) with accompanying polypoidal lesions in eyes with polypoidal choroidal vasculopathy (PCV). DESIGN Retrospective observational case series. METHODS For this observational case study, we retrospectively reviewed 93 consecutive eyes of 85 patients with PCV. The lesions in eyes with PCV were examined with indocyanine green angiography (IA) and optical coherence tomography (OCT). RESULTS Of 93 eyes with PCV, 51 eyes (55%) had serous or hemorrhagic PEDs. Of these 51 eyes, a notch in the PED was found in 27 eyes (53%) by angiography, most of which showed polypoidal lesions by IA that corresponded in location to the notch observed by angiography. Polypoidal lesions were detected outside the PED in one eye (2%), at the margin of the PED in 33 eyes (65%), and inside the PED in 12 eyes (24%). OCT revealed that PED had a notch observed tomographically in 29 eyes (57%), most of which corresponded in location to polypoidal lesions seen by IA. In eight eyes, polypoidal lesions, which were adherent to the inner surface of the serous PED, appeared to be detached from the Bruch membrane and the choroid. CONCLUSIONS Polypoidal lesions are located at the margin of PED and make a notch in the accompanying PED that is visible by angiography and tomographically. When the polypoidal lesions have increased exudate, the fluid from the lesions infiltrates under the polypoidal lesions themselves, which results in the lesions detaching from the Bruch membrane and appearing to be located inside the PED.

Abstract
PURPOSE To describe polypoidal choroidal vasculopathy as a complication of tilted disk syndrome and high myopia with staphyloma. DESIGN Retrospective interventional case series. METHODS This report was a multicenter evaluation of six patients (eight eyes) with tilted disk syndrome or high myopia that was complicated by posterior staphyloma. Complete ophthalmic examination that included fluorescein angiography, optical coherence tomography (OCT), and indocyanine green angiography (ICG-A) was performed in all patients. RESULTS All patients had macular abnormalities and visual loss. Fundus examination and fluorescein angiography showed typical features of tilted disk syndrome (five patients; six eyes) or high myopia (one patient; two eyes) with staphyloma that was associated with polypoidal choroidal vasculopathy. OCT and ICG-A confirmed the presence of polypoidal dilations in the choroid. Seven eyes were treated with laser photocoagulation or verteporfin-photodynamic therapy (V-PDT), although one eye did not require treatment. Visual acuity at the final visit had improved in three eyes, deteriorated in three eyes, and remained unchanged in two eyes. CONCLUSION Polypoidal choroidal vasculopathy is a potential cause of visual loss in tilted disk syndrome and high myopia. We postulate that choroidal abnormalities at the border of staphylomas induce blood-flow disturbances that are similar to those disturbances that are observed in chronic central serous chorioretinopathy, which is another condition that occasionally is associated with polypoidal choroidal vasculopathy. The pathogenesis remains unclear, and further study is required to better understand the formation of choroidal polypoidal dilations in these conditions.

Abstract
PURPOSE To determine the percentage of Japanese patients with age-related macular degeneration (AMD) who are eligible for photodynamic therapy (PDT) with verteporfin who have either polypoidal choroidal vasculopathy (PCV) or choroidal neovascularization (CNV) with retinochoroidal anastomosis (RCA). METHODS The medical charts of 82 consecutive patients (83 eyes) with subfoveal CNV due to AMD were reviewed. Initially, we determined which of these eyes were eligible for PDT by using the criteria reported by two large randomized control studies, that is, the Treatment of Age-related Macular Degeneration with Photodynamic Therapy (TAP) study and the Verteporfin in Photodynamic Therapy (VIP) study. Among the PDT-eligible patients, the percentage of eyes with PCV or CNV with RCA was determined by indocyanine green angiography (ICGA). RESULTS In total, 36 eyes (43%) of the 83 eyes were PDT-eligible; 17 (20%) based on the TAP study criteria, and 19 (23%) based on the VIP study criteria. Among these PDT-eligible eyes, ICGA revealed that 12 (33%) had PCV and 2 (6%) had CNV with RCA. CONCLUSIONS With ICGA, PCV or CNV with RCA were recognized in a substantial proportion of cases eligible for PDT based on the two clinical studies. Considering that the treatment efficacy of PDT for PCV or RCA has not been established, detection of PCV or RCA prior to PDT with ICGA is highly recommended.

Abstract
AIM To compare and evaluate the transitions in retinal function after photodynamic therapy (PDT) between age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) using multifocal electroretinograms (mfERGs). METHODS 10 eyes with choroidal neovascularisation (CNV) secondary to AMD and 11 eyes with CNV secondary to PCV were included in the study. mfERGs were recorded before PDT, and 1 week and 3 months after PDT. mfERG recordings were acquired by a Veris system (V.3.1.3) using a 103 hexagon stimulus. The first-order kernel was used to calculate amplitudes and latencies. Mean amplitudes and latencies from two central rings rated 0-4 degrees of visual angle were analysed and compared with each disease. RESULTS In AMD, the mean first negative peak (N1) amplitudes tended to decrease, and the mean first positive peak (N1P1) amplitudes reduced to significant levels (p = 0.047) 1 week after PDT. 3 months after PDT, there were no significant differences in the mean N1 and N1P1 amplitudes compared with pre-PDT values. In PCV, there were no significant changes in the mean N1 and N1P1 amplitudes 1 week after treatment. However, 3 months after PDT, mean amplitudes showed significant increases in N1 (p = 0.008) and N1P1 (p = 0.006) amplitudes compared with pre-PDT values. CONCLUSIONS mfERG recording transitions are different between patients with AMD and those with PCV. In patients with AMD, these results may show transient impairments in retinal function 1 week after PDT, but in those with PCV, the efficacy of PDT is superior to the impairment after PDT.

Abstract
PURPOSE We reviewed the indications, safety, and efficacy of photodynamic therapy with verteporfin in various macular diseases and vasculopathies, which are common in Asian populations, and compared the outcomes of photodynamic therapy in Asian patients with the outcomes in Caucasian patients. METHODS Relevant clinical and laboratory original articles, case reports, and review articles that have been published in the literature between January 1999 and October 2004 were searched in Medline. The potential differences in the response to photodynamic therapy between Asian and Caucasian patients were evaluated. Articles in foreign languages with English abstracts were included. RESULTS Macular diseases commonly seen in Asian populations, including choroidal neovascularization (CNV) of age-related macular degeneration, secondary to pathologic myopia or from an idiopathic cause, and choroidal vasculopathies such as central serous chorioretinopathy and polypoidal choroidal vasculopathy were included in the review. The results were tabulated and the differences with Caucasian populations were compared and highlighted. CONCLUSION Photodynamic therapy has been found to be an effective and noninvasive treatment for various subfoveal CNV and choroidal vasculopathies of the macula. Diverse behavior in different ethnic groups is observed.

Abstract
BACKGROUND Polypoidal choroidal vasculopathy (PCV) with peculiar vascular lesions presents frequently as recurrent submacular haemorrhage. The best treatment is still not certain. It is the authors' objective to evaluate the 1-year safety and efficacy of photodynamic therapy (PDT) using verteporfin for persistent macular PCV after pneumatic displacement of the massive submacular haemorrhage with intravitreal perfluoropropane (C(3)F(8)). METHODS A prospective, non-comparative, interventional case series on patients with extensive and thick submacular haemorrhage secondary to PCV, which was displaced pneumatically with intravitreal pure 0.4 ml C(3)F(8). Fluorescein angiography and indocyanine green angiography were repeated 1-2 weeks later to delineate any persistent active leaking polypoidal lesions, which were then treated with PDT. Retreatment might be considered in each follow up at every 3 months. RESULTS Six eyes of six patients with the mean age of 53.6 years had been recruited and completed 1-year follow up. The mean baseline Snellen equivalent best-corrected visual acuity (BCVA) was 6/92 and the mean final BCVA at 1 year was 6/17. The mean improvement in logMAR BCVA after the sequential treatments was seven lines (range +3 to +19 lines) (Wilcoxon signed-ranks test, P = 0.03). All patients had at least moderate visual gains. No patient suffered serious complications from PDT. CONCLUSIONS This first report on combined treatment with intravitreal gas injection and sequential PDT on PCV seems to be a well-tolerated option. Further comparative studies with larger sample size and longer follow up are warranted.

Abstract
BACKGROUND We evaluated, in a nonrandomised, institutional, prospective study, the efficacy of photodynamic therapy (PDT) with verteporfin in age-related macular degeneration (AMD) eyes with polypoidal choroidal vasculopathy (PCV) and subfoveal exudation. METHODS A prospective clinical and angiographic study was done in 40 consecutive eyes with PCV treated with PDT using masked best-corrected visual acuity (VA) and fluorescein and indocyanine green angiographic features at baseline and over 2 years. RESULTS Twenty-one eyes completed 1-year follow-up and showed, after a mean 2.9 PDT sessions, VA improvement in 12 eyes, no change in five eyes, and VA decrease in four eyes. Leakage was absent at the retinal and choroidal level in 14 eyes at 1 year. Recurrence occurred in one eye during the first year. Six eyes completed 2 years of follow-up and showed, after a mean 4 PDT sessions, VA improvement in five eyes and VA decrease in one eye. Leakage was absent at the retinal and choroidal level in five eyes. Recurrence occurred in four of these six eyes during the second year of follow-up. No serious adverse events were observed during the 2 years of follow-up. CONCLUSIONS PDT with verteporfin was shown to be safe and effective for treating AMD eyes with PCV with subfoveal involvement. VA improvement and absence of leakage were achieved, respectively, in 57.1% and 66.6% of the eyes at 1 year. Recurrences were more frequent during the second year of follow-up.

Abstract
Macular exudative manifestations secondary to choroidal neovascular lesions remain the leading cause of definitive visual impairment and legal blindness in the elderly. During the past decade, advances in ophthalmic imaging systems have enabled the recognition of presumed new distinct choroidal neovascular lesions that share some unique clinical and angiographic peculiarities as well as better comprehension of the pathophysiologic mechanisms related to such entities. Amongst presumed newer exudative maculopathies, polypoidal choroidal vasculopathy, which has been described as a distinct choroidal abnormality characterized by inner choroidal vascular network of vessels ending in polyp-like structures only identified on indocyanine green angiography and mostly affecting African-American and Asian descendents, has gained special interest from the ophthalmic community particularly because of its growing recognition among patients with clinical appearance of neovascular age-related macular degeneration. Thus far, however, the exact nature of the vascular structure of the polypoidal choroidal vasculopathy lesion remains unclear and data from recent studies have conflicted with the initial concept of a benign exudative maculopathy with long-term preservation of good vision. All together, such factors make difficult the establishment of an appropriate treatment, if any, for the entity. Herein, by using a modified technique of conventional indocyanine green angiography, we demonstrate new information about the morphologic characteristics, and to some extent the blood flow dynamics perfusion, of the polypoidal choroidal vasculopathy lesion. Our results suggest that the PCV lesion should be considered a variety of choroidal neovascularization rather than a distinct clinical entity, characterized by one single large neovascular complex presenting well-defined arterial neovascular vessels arising from one major "ingrowth site" and draining vessels that present aneurysm-like dilations corresponding to the polyp-like structures typically described for the entity. Finally, the visual acuity and angiographic findings observed after selective ingrowth site photothrombosis corroborate the existence of one major "ingrowth site" for the PCV neovascular complex and point toward a new treatment paradigm for this variety of choroidal neovascularization.

Abstract
OBJECTIVE To describe patients with pulsatile polypoidal vessels in polypoidal choroidal vasculopathy (PCV). DESIGN Retrospective, observational case series. PARTICIPANTS Eighty-four eyes of 74 patients with PCV. METHODS The medical records of patients diagnosed with PCV between 1998 and 2004 at Kagoshima University Hospital were reviewed. MAIN OUTCOME MEASURES A pulsatile polypoidal vessel (PV) on indocyanine green angiography (ICGA). RESULTS Seven of 74 patients (9.5%) had PVs in the macula. Four eyes revealed pulsatile PVs on the day the diagnosis of PCV was first made, and PVs in the other 3 eyes showed pulsatile movement during the follow-up period. Two patterns of pulsatile movement were observed on ICGA: (1) a rhythmic variation in the caliber of a choroidal vessel (caliber variation pattern) and (2) a pulsatile blood flow in a tortuous and relatively narrow choroidal vessel (pulsatile blood flow pattern). Both patterns of pulsatile PVs appeared in the early frames of the ICGA, and some of them were observable even during the first 15 minutes after the ICG dye injection. The pulsatile movement disappeared spontaneously without treatment in some patients, and the period in which pulsatile PVs was detectable on ICGA was limited in each patient. CONCLUSIONS We report the features of pulsatile PV in PCV. It is a unique and important characteristic that has not been reported with any other chorioretinal diseases and may provide a clue to understanding the pathogenesis of PCV.
