Abstract
PURPOSE To investigate the imaging and clinical features of polypoidal choroidal vasculopathy (PCV) with pulsation. METHODS The PCV eyes were classified into pulsatile and nonpulsatile PCV groups according to the pulsation on indocyanine green angiography. Imaging features including the dye filling time of the polyp and clinical features were compared. RESULTS A total of 75 eyes were classified into the pulsatile PCV (30 eyes) and the nonpulsatile PCV (45 eyes) groups. The initial filling time and complete filling time of the polyp of the pulsatile PCV group (2.59 ± 0.93 and 8.33 ± 3.42 seconds) were shorter than those of the nonpulsatile PCV group (4.11 ± 1.87 and 10.63 ± 3.81 seconds, P < 0.001 and P = 0.010, respectively). The pigment epithelial detachment height of the pulsatile PCV group (414.90 ± 377.15 µ m) was greater than that of the nonpulsatile PCV group (247.81 ± 164.07 µ m, P = 0.030). The pulsatile PCV group showed a higher prevalence of subretinal hemorrhage (43.33%) after intravitreal injection than the nonpulsatile PCV group (13.95%, P = 0.005) during 12 months. The mean number of injections during 12 months of the pulsatile PCV group (5.48 ± 1.46) was greater than that of the nonpulsatile PCV group (4.09 ± 1.21, P < 0.001). CONCLUSION Eyes with pulsatile PCV showed shorter filling time of the polyp, greater pigment epithelial detachment height, higher prevalence of subretinal hemorrhage, and more intravitreal injection numbers during 12 months. These might suggest that PCV has distinct imaging and clinical features according to the polyp pulsation.

Abstract
PURPOSE Over the past two decades, advancements in imaging modalities have significantly evolved the diagnosis and management of retinal diseases. Through these novel platforms, we have developed a deeper understanding of the anatomy of the choroidal vasculature and the choriocapillaris. The recently developed tools such as optical coherence tomography (OCT) and OCT angiography (OCTA) have helped elucidate the pathological mechanisms of several posterior segment diseases. In this review, we have explained the anatomy of the choriocapillaris and its close relationship to the outer retina and retinal pigment epithelium. METHODS A comprehensive search of medical literature was performed through the Medline/PubMed database using search terms: choriocapillaris, choroid, quantification, biomarkers, diabetic retinopathy, age-related macular degeneration, choroidal blood flow, mean blur rate, flow deficit, optical coherence tomography, optical coherence tomography angiography, fluorescein angiography, indocyanine green angiography, OCTA, Doppler imaging, uveitis, choroiditis, white dot syndrome, tubercular serpiginous-like choroiditis, choroidal granuloma, pachychoroid, toxoplasmosis, central serous chorioretinopathy, multifocal choroiditis, choroidal neovascularization, choroidal thickness, choroidal vascularity index, choroidal vascular density, and choroidal blood supply. The search terms were used either independently or combined with choriocapillaris/choroid. RESULTS The imaging techniques which are used to qualitatively and quantitatively analyze choriocapillaris are described. The pathological alterations in the choriocapillaris in an array of conditions such as diabetes mellitus, age-related macular degeneration, pachychoroid spectrum of diseases, and inflammatory disorders have been comprehensively reviewed. The future directions in the study of choriocapillaris have also been discussed. CONCLUSION The development of imaging tools such as OCT and OCTA has dramatically improved the assessment of choriocapillaris in health and disease. The choriocapillaris can be delineated from the stromal choroid using the OCT and quantified by manual or automated methods. However, these techniques have inherent limitations due to the lack of an anatomical distinction between the choriocapillaris and the stromal choroid, which can be overcome with the use of predefined segmentation slabs on OCT and OCTA. These segmentation slabs help in standardizing the choriocapillaris imaging and obtain repeatable measurements in various conditions such as diabetic retinopathy, age-related macular degeneration, pachychoroid spectrum, and ocular inflammations. Additionally, Doppler imaging has also been effectively used to evaluate the choroidal blood flow and quantifying the choriocapillaris and establishing its role in the pathogenesis of various retinochoroidal diseases. As tremendous technological advancements such as wide-field and ultra-wide field imaging take place, there will be a significant improvement in the ease and accuracy of quantifying the choriocapillaris.

Abstract
Purpose To describe a patient in whom a pulsating choroidal vascular lesion was observed during vitrectomy for the treatment of vitreous hemorrhage secondary to polypoidal choroidal vasculopathy (PCV). Observations A 67-year-old Chinese male was referred to our department for the treatment of vitreous hemorrhage secondary to PCV in his right eye. PCV was confirmed during surgery, accompanied by extensive vitreous and subretinal hemorrhage, and exudation in the posterior pole and temporal to the fovea. A reddish-orange pulsatile lesion was observed at the inferotemporal fundus. The pulsatility of the lesion varied with changes in the intraocular infusion pressure. The pulsating lesion was not visible on fluorescein and indocyanine green angiography performed 1 month after surgery. Conclusions and importance A pulsatile choroidal vascular lesion was observed during vitrectomy. Future studies elucidating the relationships between pulsation, intraocular pressure, and blood flow would help our understanding of the hemodynamics of polypoidal choroidal vessels.

Abstract
PURPOSE To investigate the incidence rate of massive submacular haemorrhage (SMH) and risk factors in polypoidal choroidal vasculopathy (PCV) and typical neovascular age-related macular degeneration (tnAMD). METHODS A total of 465 patients who were diagnosed with either PCV (n = 245) or tnAMD (n = 220) from 2003 to 2014 were enrolled. Cumulative incidence of massive SMH in PCV and that in tnAMD were compared. Risk factors of massive SMH were also analysed. RESULTS Massive SMH occurred in 32 patients (13.1%) with PCV and 9 patients (4.1%) with tnAMD. Incidence rates of massive SMH 5 and 10 years after the first visit were 11.1% and 29.9% in PCV and 4.3% and 9.9% in tnAMD, respectively. Incidence rates of massive SMH in PCV were significantly higher than those in tnAMD (hazard ratio [HR], 2.66; p = 0.007). Cox regression analysis revealed that mean number of photodynamic therapies (PDTs) per year (HR, 4.24; p < 0.001), cluster type of polypoidal lesion (HR, 3.42; p = 0.003) in PCV, and mean number of anti-VEGF injections per year (HR, 1.58; p < 0.001) in tnAMD were significantly associated with risk of massive SMH. For patients with severe vision loss, proportion of incident massive SMH was significantly higher in PCV (29.5%) than in tnAMD (6.9%, p < 0.001). CONCLUSION The incidence rate of massive SMH in eyes with PCV was about three times higher than that in eyes with tnAMD. Treatment methods that can reduce the incidence of massive SMH should be considered, especially for eyes with PCV.

Abstract
PURPOSE To describe pulsatile filling of dilated choroidal veins in the watershed zones and propose an alteration in choroidal perfusion pressure. METHODS Retrospective review of original and digital subtraction indocyanine green angiography (ICGA). RESULTS We observed pulsating blood flow within choroidal vein segments in the posterior pole in 14 eyes (diagnosis of polypoidal choroidal vasculopathy, central serous chorioretinopathy, or neovascular age-related macular degeneration). Pulsating dye front was observed in single or multiple large choroidal vein(s) in a location that is ordinarily a watershed zone between the segmental areas of venous drainage and vessels proximal and distal were often dilated. The pulsatile venous segments filled more slowly that the neighboring veins. In digital subtraction ICGA, the dye front advanced in an incremental fashion or oscillated in a back-and forth manner during several cardiac cycles during the filling of these larger choroidal veins. With ICGA, we observed dilated choroidal veins which violated the macula watershed zone, localized bulbous dilations, and arteriole-over-vein crossings with apparent compression. CONCLUSIONS These novel observations suggest the pressure gradient for flow in the affected veins varied, from low gradients when the filling was slow to higher gradients when the filling was faster. The vessels violated the physiological watershed zone and seem to function as anastomoses between the ordinarily segmented venous drainage of the choroid. The dilated segments may result in pooling of venous blood as part of venous outflow abnormalities that may be operative in these diseases.

Abstract
BACKGROUND To describe the clinical presentation and characteristic imaging features of deep retinal haemorrhages primarily located in the Henle fibre layer (HFL) of the macula. The spectrum of aetiologies and a comprehensive theory of pathogenesis are presented. METHODS This is a retrospective, multicentre case series evaluating eyes with retinal haemorrhage in HFL. Clinical features, underlying aetiology, systemic and ocular risk factors, visual acuity, and multimodal imaging including fundus photography and cross-sectional and en face optical coherence tomography (OCT) are presented. RESULTS Retinal haemorrhages localised to HFL in 33 eyes from 23 patients were secondary to acute blunt trauma to the head (n=2), eye (n=1) and trunk (n=1), ruptured intracranial aneurysm (Terson's syndrome, n=3), general anaesthesia (n=1), epidural anaesthesia (n=1), hypertension with anaemia (n=1), decompression retinopathy (n=1), postvitrectomy with intraocular gas (n=1), retinal vein occlusion (n=7), myopic degeneration (n=2), macular telangiectasia type 2 (n=1), and polypoidal choroidal vasculopathy (n=1). Defining clinical features included deep retinal haemorrhage with feathery margin and petaloid pattern radiating from the fovea. OCT demonstrated characteristic hyper-reflectivity from the haemorrhage delineated by obliquely oriented fibres in the Henle layer. Spontaneous resolution of HFL haemorrhage occurred after 3 months in 15 patients with follow-up. CONCLUSION The characteristic petaloid-shaped, deep intraretinal haemorrhage with a feathery margin localised to HFL is associated with various disorders. The terminology 'Henle fiber layer hemorrhage (HH)' is proposed to describe the clinical and OCT findings, which may result from abnormal retinal venous pressure from systemic or local retinovascular disorders affecting the deep capillary plexus or from choroidal vascular abnormalities.

Numerous retinal pigment epithelial elevations and drusen associated with unusual dilated choroidal vessels seen at choriocapillaris level in macular area. Am J Ophthalmol Case Rep 2020; 18:100634. [PMID: 32154436 PMCID: PMC7056621 DOI: 10.1016/j.ajoc.2020.100634] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 01/27/2020] [Accepted: 02/24/2020] [Indexed: 11/22/2022] Open
Abstract
Purpose To report the ocular findings in a patient with extensive diffuse elevations of the retinal pigment epithelium (RPE) and drusen associated with dilated choroidal vessels. Observations The eye of a 72-year-old woman with numerous drusen and dilated choroidal vessels in the macular and surrounding areas of the right eye was studied. Her visual acuity was 20/16 in this eye and she was asymptomatic although the Amsler grid testing showed mild metamorphopsia. Indocyanine green angiography showed dilated choroidal vessels that collected blood from their branches in the macular and surrounding areas and flowed out of the eye at the entry site of a short posterior ciliary artery. A large choroidal vein ran from the nasal quadrants toward the superotemporal quadrant. Optical coherent tomography (OCT) showed two types of RPE elevations over an extensive area: one was a relatively steep dome-shaped RPE elevation, and the other was a flatter placoid-shaped RPE detachment. Detailed examinations including OCT angiography showed that the dome-shaped RPE elevation coincided with the course of the dilated choroidal vessels which were seen at the level of the choriocapillaris. The visual acuity and the ocular findings remained stable during the 2.5-year follow-up period, and this condition did not require any treatments. Conclusions and importance We conclude that the dilated choroidal vessels are most likely parts of the posterior ciliary venous system, and they function as a posterior route of choroidal outflow. Because such eyes might be diagnosed and treated as age-related macular degeneration based on the presence of drusen, RPE detachments, and abnormal vessels beneath the RPE, knowledge of these observations in a functionally normal eye is important to avoid unnecessary treatments.

Abstract
PURPOSE The recent introduction of anti-VEGF drugs has widely changed the prognosis of exudative age-related macular degeneration (AMD), even if a variable percentage of patients showed an insufficient response. Aflibercept is a new anti-VEGF drug approved by FDA for the treatment of exudative AMD with a wider binding capacity than either bevacizumab or ranibizumab. Therefore, the purposes were as follows: (i) to report anatomical and functional outcomes of switching from bevacizumab/ranibizumab to aflibercept previously described in the scientific literature, (ii) to hypothesize the possible pathophysiological mechanisms of the resistance and tachyphylaxis to anti-VEGF drugs, and (iii) to suggest possible clinical actions to increase the chances of success for such difficult cases. METHODS We reviewed the available scientific literature in Medline, Cochrane database, Current Contents, PubMed, and cross-referencing from identified articles, regarding the treatment of exudative AMD patients refractory to bevacizumab and/or ranibizumab and switched to aflibercept monotherapy. We included in this review all the cases in which the diagnosis of refractory or resistant exudative AMD was properly made, and the results of at least one aflibercept injection were described. FINDINGS We reported the outcomes of 21 papers for a total of 1066 eyes affected by exudative AMD resistant to previous anti-VEGF drug injections and switched to aflibercept. Enrolled reports were divided into two groups: 5 prospective reports and 16 retrospective reports. All the reported papers conclude their analysis, stating that switching from bevacizumab/ranibizumab to aflibercept injections can improve outcomes successfully in refractory neovascular AMD patients. IMPLICATIONS Analysis of the papers reported in this review demonstrates that switching from bevacizumab/ranibizumab to aflibercept injections can improve outcomes successfully in refractory neovascular AMD patients. The mechanism for these effects is not yet completely understood.

Abstract
Age-related macular degeneration (AMD) is the major reason for blindness affecting about 50 % of blind people in Germany. Early forms of AMD with drusen and pigment epithelium changes can be detected in 20 % of patients over 65 years old. The dry form of AMD causes slow deterioration of visual acuity, which cannot currently be adequately treated. In contrast development of a choroidal neovascularization (CNV) membrane results in rapid visual loss which will become permanent if treatment is not started immediately. Using anti-vascular endothelial growth factor (VEGF) agents stabilization and improvement of visual acuity is possible. Special types of AMD, such as retinal angiomatous proliferation and polypoidal choroidal vasculopathy are much less common. The natural course of the diseases can be very different, end stages often result in scarring and anti-VEGF agents are only weakly effective.

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

Abstract
PURPOSE This pilot study was conducted to describe the angiographic characteristics of inactive polypoidal lesions that were observed during indocyanine green angiography (ICGA) in polypoidal choroidal vasculopathy (PCV). METHODS This was a retrospective study involving 40 eyes of 39 consecutive Chinese patients with PCV with inactive polypoidal lesions. All patients underwent fundus fluorescein angiography and ICGA examinations. We used ICGA to make a definitive diagnosis of PCV in each patient. The clinical and angiographic characteristics of inactive polypoidal lesions were recorded and analyzed. RESULTS In the 40 eyes that were studied, the time between receiving an injection of indocyanine green and the initial appearance of inactive polypoidal lesions ranged from 8.2 minutes to 25.1 minutes, with a mean time of 15.1 ± 5.6 minutes. Inactive polypoidal lesions were divided into 4 groups: 5 eyes (12.5%) in the asymptomatic group; 8 eyes (20.0%) in the atrophic and/or cicatricial group; 24 eyes (60.0%) in the combined group (coexisting with active polypoidal lesions); and 3 eyes (7.5%) in the mixed group (coexisting with choroidal neovascularization). Twelve of the 40 eyes were followed up for 9 to 29 months (mean 12.4 ± 5.3 months). Over this time period, inactive polypoidal lesions completely regressed (not observed in ICGA) in 3 eyes (25.0%), partially regressed in 3 eyes (25.0%), and were stable (the same as the first visit) in 6 eyes (50.0%). CONCLUSIONS Inactive polypoidal lesions in patients with PCV most commonly appeared during the middle phase of ICGA and were manifested in 4 groups. These lesions represented the sites of PCV in a regressed or quiescent stage.

Abstract
Polypoidal choroidal vasculopathy (PCV) is currently recognized as a phenotype of age-related macular degeneration (AMD). PCV is believed to be a type of choroidal neovascularization, although some cases of PCV show a distinct vascular abnormality of the choroidal vessels. PCV often shows several unique clinical manifestations which are apparently different from typical neovascular AMD (tAMD). In addition, the natural course and response to treatment are often different between tAMD and PCV. Moreover, recent genetic studies suggested a possible difference in the genetic susceptibility to disease between tAMD and PCV, as well as the existence of heterogeneity among PCV cases. In viewing the accumulation of knowledge about PCV, we have summarized the recent literature regarding PCV in this review article to improve the understanding of this clinical entity including possible susceptibility genes. We will also discuss the optimal treatment strategies for PCV in accordance with the results of recent clinical and genetic studies.

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
It has been reported that pulsations in abnormal vessels are observed on indocyanine green (ICG) angiography in half of patients with polypoidal choroidal vasculopathy (PCV), although the mechanism of the pulsation is unknown. In this study, we report a case of PCV showing venous pulsations at an arterio-venous (A-V) crossing, and discuss a possible mechanism of polypoidal vessel formation and pulsations in PCV. A 66-year-old female presented with a reddish-orange elevated lesion and serous retinal detachment in the macula of her left eye, and was diagnosed as PCV. She was treated with photodynamic therapy (PDT), and followed-up through routine examinations, including ICG angiography. ICG angiography at presentation showed a branching vascular network and choroidal venules with dye leakage (polypoidal vessels) in the left eye. Pulsations, supposedly of venous origin, were observed at an A-V crossing in the abnormal vessels. Within 3 months after PDT, the polypoidal vessel ceased to leak and the pulsations vanished. The reddish-orange lesion gradually decreased in size with complete disappearance of retinal detachment. This study suggests that an unusual compression at an A-V crossing may make a venule polypoidal, and fluctuations of blood flow and pressure in the venule may cause pulsatile movements of the vessel wall.

Abstract
Background To determine the role played by vascular endothelial growth factor (VEGF) in polypoidal choroidal vasculopathy (PCV) based on an interventional immunology theory. Methods Eyes with PCV were divided in a masked fashion into those with choroidal hyperpermeability (HP group) and those with normal choroidal permeability (NP group) based on the indocyanine green angiograms. The inter-rater agreement rate was evaluated using Fleiss’ kappa. Patients were treated by intravitreal ranibizumab (IVB). The central choroidal thickness and central foveal thickness (CFT) at the baseline and 7 days after the treatment were measured by optical coherence tomography. Results Among the 57 consecutive eyes diagnosed with PCV, 42 eyes of 42 patients met the inclusion criteria (21 eyes/HP group vs 21 eyes /NP group). Central choroidal thickness in HP group was significantly thicker than that in the NP group (P < .001, Mann–Whitney U test). The inter-rater agreement was high with a Fleiss’ kappa = 0.95, P < .0001. The percentage reduction in the CFT in HP group (14.0%) was significantly less than that in NP group (20.4%; P = .013, Mann–Whitney U test). Conclusions Eyes with PCV that are associated with choroidal hyper-permeability may not be strongly associated with VEGF-related pathology, and may not respond favorably to anti-VEGF monotherapy.

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

Abstract
PURPOSE To report on the clinical course of pulsating polypoidal choroidal vasculopathy (PCV) treated with photodynamic therapy (PDT). METHODS A total of 63 eyes of 58 consecutive patients diagnosed with PCV, treated with PDT and followed up for at least 6months were enrolled. Best-corrected visual acuity (BCVA), fluorescein angiography and high-speed indocyanine green angiography (ICGA) using confocal scanning laser ophthalmoscopy (HRA) were performed. RESULTS Of the 63 PCV eyes, 14 eyes (22.2%) of 14 patients were classified as having pulsating PCV. The mean age of pulsating PCV patients was 60.6±7.0years (48-69years), which was younger than non-pulsating PCV patients (65.7years, p=0.035). The mean follow-up period was 23.9±10.7months, and PDT was administered 1.6±0.9 times to pulsating PCV patients. The mean logMAR BCVAs were 0.85±0.47 at presentation and 0.71±0.52 at final examination. Extensive haemorrhagic events were more common in pulsating than in non-pulsating PCV patients (57.1% versus 26.5%, p=0.032). However, the risk of haemorrhage within 3months of PDT was similar for both pulsating PCV and the remaining patients (14.3% versus 20%, p=0.723). CONCLUSION Pulsating PCV showed distinctive features including a relatively younger patient age at presentation, and a haemorrhagic tendency (especially extensive). However, the use of PDT did not directly increase the risk of haemorrhage in pulsating PCV patients.

Abstract
PURPOSE The purpose of this study was to study the effect of pars plana vitrectomy (PPV) for age-related macular degeneration with vitreous hemorrhage on choroidal neo-vascularization (CNV). METHODS A retrospective interventional case series in which 92 eyes with age-related macular degeneration with vitreous hemorrhage that received PPV were studied. Among them, 60 eyes without pre- or posttreatment other than PPV were selected. Choroidal neovascularization was expressed as the incidence of bleeding 6 months before and after PPV. The status of CNV after PPV was compared and classified as worsened, remained, regressed, disappeared, or unclassified. The influence of posterior vitreous detachment was examined. RESULTS The incidence of bleeding was reduced dramatically after PPV (1.11 +/- 0.44 in preoperative 6 months vs. 0.03 +/- 0.18 in postoperative 6 months, P < 0.0001). The status of CNV improved in most cases; 40 of 54 classifiable eyes (74.1%) were categorized as "regressed" or "disappeared." Postoperative visual acuity was significantly better than preoperative visual acuity (P < 0.0001). The status of CNV subsided more in those eyes without posterior vitreous detachment than in those with posterior vitreous detachment (odds ratio, 1.02; 95% confidence interval, -0.01-2.08; P = 0.054). CONCLUSION The activity of CNV was reduced after PPV in eyes with age-related macular degeneration with vitreous hemorrhage. Visual acuity significantly improved, with only rare severe complications. The involvement of vitreomacular traction in the patho-physiology of CNV in age-related macular degeneration is possible.

Abstract
PURPOSE To find predictable signs of benign polypoidal choroidal vasculopathy (PCV). METHODS Medical records of 13 eyes from 12 patients who were followed up for 5 years or longer without treatment among 258 consecutive patients with PCV were reviewed retrospectively. The main outcomes measured were best corrected visual acuity (BCVA) and fundus findings during the follow-up period. RESULTS The average age at presentation was 68 years, and the average follow-up period after diagnosis was 80 months (range, 62-119 months). The initial mean logarithmic value of the minimal angle of resolution (logMAR) BCVA was 0.28 +/- 0.26, and the final mean logMAR BCVA was 0.62 +/- 0.72. The difference in the logMAR BCVA values between the two points was not statistically significant (p > 0.05). The trend of change from baseline at 2-year follow-up was consistent with those at 5-year follow-up in nine eyes. Fundus findings at the initial examination were classified into two patterns: (i) reddish-orange nodules and detachment of the retinal pigment epithelium with/without detachment of the neurosensory retina (nine eyes); (ii) reddish-orange nodules alone, or nodules and small subretinal haemorrhage (four eyes). In the eyes with the first pattern, clinical course and visual prognosis were variable. An absence of hard exudates could be a sign to maintain a benign clinical course or stable vision with this pattern. The eyes with the second pattern took a benign clinical course with stable vision. CONCLUSIONS There is certainly a group of PCV eyes with a benign prognosis. Considering the huge cost and risk of current therapies, the initial ocular findings could be deciding factors that determine the necessity for further treatment.

Abstract
PURPOSE OF REVIEW This review assesses the current knowledge of the clinical characteristics of polypoidal choroidal vasculopathy and treatments. RECENT FINDINGS Polypoidal choroidal vasculopathy is a disease with characteristic choroidal vascular abnormalities. Indocyanine green angiography is essential for diagnosis. The prevalence is higher in Asian people than in Caucasians. Photodynamic therapy is efficacious for treating polypoidal choroidal vasculopathy; 1-year results have shown greater benefit of photodynamic therapy than choroidal neovascularization secondary to age-related macular degeneration. Recurrence, however, seriously affects vision long term during follow-up after photodynamic therapy. The lower efficacy of bevacizumab- a full-length antibody of vascular endothelial growth factor- has been shown for polypoidal choroidal vasculopathy. SUMMARY Although the polypoidal choroidal vasculopathy and age-related macular degeneration have been known to share common genetic factors, its clinical characteristics including the different responses to photodynamic therapy suggest that polypoidal choroidal vasculopathy is a separate clinical entity from age-related macular degeneration. The results of photodynamic therapy for polypoidal choroidal vasculopathy are encouraging; however, recurrence may affect vision over time. Therapeutic modalities to inhibit development of the exudative choroidal vasculature of polypoidal choroidal vasculopathy are desirable.
