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

Abstract
Importance The EVEREST II trial showed that for patients with polypoidal choroidal vasculopathy (PCV), intravitreal ranibizumab in combination with verteporfin photodynamic therapy improves visual acuity relative to ranibizumab monotherapy. However, whether combination therapy is incrementally cost-effective relative to monotherapy during a lifetime is unclear. Objective To assess the incremental cost-effectiveness of combination therapy compared with ranibizumab monotherapy in patients with PCV. Design, Setting, and Participants This model-based, economic evaluation used 2018 unit cost data from a tertiary eye hospital in Singapore, first- and second-year outcomes and resource use data from a multicenter trial across various Asian countries (EVEREST II) to model a hypothetical cohort of patients with symptomatic PCV. Scenario analyses and deterministic and probabilistic sensitivity analyses were performed to examine uncertainty. Data were collected from October 2018 through April 2019 and analyzed from March through October 2019. Interventions This model used data from the EVEREST II trial, in which all participants were given 0.5 mg of intravitreal ranibizumab once every 4 weeks for the first 3 months. Subsequent administration occurred as needed. For participants receiving combination therapy, standard fluence (50 J/cm3) photodynamic therapy with 6-mg/m2 verteporfin was administered once during the first 3 months and thereafter as needed. Main Outcomes and Measures Incremental cost per quality-adjusted life-year (QALY) gained for combination therapy relative to monotherapy for patients with PCV. Results In this model based on a cohort of 1000 patients aged 68 years, a patient with PCV incurred a total cost in Singapore dollars (SGD) of 92 327 (US $67 399) with combination therapy and SGD 92 371 (US $67 431) with monotherapy during a lifetime horizon, generating a modest cost savings of SGD 44 (US $32) per patient undergoing combination therapy. Lifetime QALYs were estimated to be 7.87 for combination therapy and 7.85 for monotherapy, for an incremental gain of 0.02 QALYs. Combination therapy remained cost-saving or cost-effective in all lifetime scenarios modeled, but during shorter time horizons and at lower monotherapy costs, it may not be cost-effective. Conclusions and Relevance This study found combination therapy to be a dominant (more effective and less costly) strategy, being similar in costs and slightly more effective than ranibizumab monotherapy during a lifetime horizon. However, decreasing the time horizon to less than 10 years and/or reductions in the cost of monotherapy may result in combination therapy no longer being cost-effective.

Abstract
Polypoidal choroidal vasculopathy (PCV) is the predominant subtype of exudative age-related macular degeneration in Asians. Although photodynamic therapy (PDT) is widely used for PCV treatment, its long-term beneficial effects are unsatisfactory. Accumulating clinical investigations suggest that combined therapy with anti-vascular endothelial growth factor (anti-VEGF) and PDT is superior to PDT monotherapy. However, the optimal time of anti-VEGF before or after PDT remains controversial, hence it needs to further explore the mechanism underlying combined therapy. PDT causes selective damage to endothelial cells, which determines its angio-occlusive efficiency, yet the impact of anti-VEGF on PDT-induced endothelial injury is unclear. Here, we found that pre- compared to post-treatment with anti-VEGF ranibizumab (rani) significantly aggravates PDT injury in the rhesus macaque choroid-retinal endothelial (RF/6A) cell line. PDT activates apoptosis, necroptosis and NLRP3 inflammasome in RF/6A cells. Pre-treatment with rani promotes PDT-caused apoptosis via triggering caspase 8-mediated extrinsic apoptosis, and caspase 8 might also play a pivotal role in the rani’s function of suppressing PDT-induced necroptosis and NLRP3 inflammasome activation. Our results implicate that pre-treatment with rani may enhance the angio-occlusive efficiency of PDT and alleviate endothelial inflammatory response, which gives it a great advantage over post-treatment.

Abstract
PURPOSE To compare the 3-year follow-up results of intravitreal injections of aflibercept between fixed dosing (FD) regimen and a pro re nata (PRN) regimen after three initial monthly doses for the treatment of polypoidal choroidal vasculopathy and to analyze factors influencing improvement in visual acuity. METHODS We retrospectively studied all treatment-naive patients with polypoidal choroidal vasculopathy who were scheduled to receive intravitreal aflibercept injections FD or PRN after induction treatment between March 2013 and May 2014. Best-corrected visual acuity was evaluated before treatment and at 4, 12, 24, and 36 months after initial treatment. Factors that influence improvement in visual acuity were also investigated. RESULTS Thirty-three eyes were assessed at the 3-year follow-up examination. Twenty-three eyes were treated with intravitreal aflibercept injections every 2 months for at least 1 year after three initial monthly doses (FD group), and 10 eyes were treated PRN after loading doses (PRN group). In the FD group, during the follow-up period from 1 to 3 years, quarterly dosing with capped PRN or a treat and extend regimen were selected. The mean number of administered intravitreal aflibercept was 15.3 ± 4.6 in the FD group and 9.0 ± 8.9 in the PRN group, with a significant difference between the two groups (P = 0.004). Significant improvement of the mean logarithm of the minimum angle of resolution values for best-corrected visual acuity was shown at 36 months, as compared to baseline values (P = 0.019). No significant difference in the improvement of best-corrected visual acuity between the two groups was observed at baseline or at 4, 12, 24, and 36 months after treatment (all P > 0.05), although there was a trend toward better results in the FD group. Multiple regression analysis showed that the FD group had better visual acuity at 36 months and greater improvement in visual acuity than the PRN group (P = 0.031 for both comparisons). CONCLUSION Intravitreal aflibercept was effective in improving the vision of patients with polypoidal choroidal vasculopathy, as evaluated at the 3-year follow-up. Fixed treatment might be an important factor influencing improvement in visual acuity.

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

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

Abstract
PURPOSE This study was prospectively carried out to clarify the effectiveness of visual and anatomical outcomes under combination therapy of intravitreal aflibercept (IVA) and verteporfin photodynamic therapy (vPDT) in over 24 months. STUDY DESIGN A single-arm prospective exploratory study. METHODS Twenty-six eyes of 26 treatment naïve PCV patients were enrolled in this study. The primary outcome measures were the changes in best corrected visual acuity (BCVA) and the complete polyp regression rate. The secondary outcome measures included central retinal thickness assessed by optical coherence tomography. RESULTS The patients showed significant improvement in BCVA by 0.14 logMAR units at 12 months and 0.11 logMAR units at 24 months from baseline (both p < 0.01). The mean central retinal thickness also significantly decreased at 12 months (p < 0.001) and at 24 months (p = 0.001). Complete regression of polypoidal lesions was achieved by 15 out of 20 eyes (75%) at 12 months and 11 out of 20 eyes (55%) at 24 months. The mean treatment number was 2.9 courses of IVA and 1.5 courses of vPDT and the mean retreatment free interval after initial therapy was 12.8 months during follow up of 24 months. The complete data from all predetermined examinations were observed in 17 out of 26 enrolled patients (65%) in this study. CONCLUSION In this study, combination therapy of IVA and vPDT yielded visual and anatomical improvements in treatment-naïve PCV patients over a 24-month follow-up period.

Abstract
AIM To report a cohort of patients with polypoidal choroidal vasculopathy (PCV) treated with photodynamic therapy (PDT) followed by intravitreal ranibizumab injection 24-48h later, and to compare the results between eyes with PCV treated by PDT followed by intravitreal anti-vascular endothelial growth factor (VEGF) injection and intravitreal anti-VEGF injection followed by PDT by Meta-analysis. METHODS Retrospective study and systematic literature review. Medical records of patients with PCV who were initially treated using PDT followed by intravitreal ranibizumab injection 24-48h after PDT and had completed at least 2y follow-up were reviewed and analyzed. Clinical data, including age, sex, best-corrected visual acuity (BCVA), fundus photograph, fluorescein angiography, indocyanine green angiography and optical coherence tomography were investigated. A systematic literature review was also conducted, and a visual outcome of studies over 1y was compared using Meta-analysis. RESULTS A total of 52 patients were included in the study. Mean BCVA at baseline and follow-up at 1 or 2y were 0.71±0.61, 0.51±0.36 and 0.68±0.51 logMAR, respectively. The cumulative hazard rate for recurrence at 1 and 2y follow-up was 15.4% and 30.3% respectively. The percentage of eyes with polyps regression at 3, 12 and 24mo follow-up was 88.5%, 84.6% and 67.3% respectively. A Meta-analysis based on 22 independent studies showed the overall vision improvements at 1, 2 and 3y follow-up were 0.13±0.04 (P<0.001), 0.12±0.03 (P<0.001), 0.16±0.06 (P<0.001), respectively. The proportion of polyps regression at 1y follow-up was 64.6% (95%CI: 51.5%, 77.7%, P<0.001) in 434 eyes treated by intravitreal anti-VEGF agents before PDT and 76.0% (95%CI: 64.8%, 87.3%, P=0.001) in 199 eyes treated by intravitreal anti-VEGF agents after PDT. CONCLUSION Intravitreal ranibizumab injection 24-48h following PDT effectively stabilizes visual acuity in the eye with PCV. PDT followed by intravitreal anti-VEGF agents may contribute to a relatively higher proportion of polyps' regression as compared to that of intravitreal anti-VEGF before PDT.

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

Abstract
AIM To compare the efficacy of intravitreal ranibizumab (IVR) alone or in combination with photodynamic therapy (PDT) vs PDT in patients with symptomatic polypoidal choroidal vasculopathy (PCV). METHODS A systematic search of a wide range of databases (including PubMed, EMBASE, Cochrane Library and Web of Science) was searched to identify relevant studies. Both randomized controlled trials (RCTs) and non-RCT studies were included. Methodological quality of included literatures was evaluated according to the Newcastle-Ottawa Scale. RevMan 5.2.7 software was used to do the Meta-analysis. RESULTS Three RCTs and 6 retrospective studies were included. The results showed that PDT monotherapy had a significantly higher proportion in patients who achieved complete regression of polyps than IVR monotherapy at months 3, 6, and 12 (All P≤0.01), respectively. However, IVR had a tendency to be more effective in improving vision on the basis of RCTs. The proportion of patients who gained complete regression of polyps revealed that there was no significant difference between the combination treatment and PDT monotherapy. The mean change of best-corrected visual acuity (BCVA) from baseline showed that the combination treatment had significant superiority in improving vision vs PDT monotherapy at months 3, 6 and 24 (All P<0.05), respectively. In the mean time, this comparison result was also significant at month 12 (P<0.01) after removal of a heterogeneous study. CONCLUSION IVR has non-inferiority compare with PDT either in stabilizing or in improving vision, although it can hardly promote the regression of polyps. The combination treatment of PDT and IVR can exert a synergistic effect on regressing polyps and on maintaining or improving visual acuity. Thus, it can be the first-line therapy for PCV.

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

Abstract
PURPOSE Ranibizumab (Lucentis(®) ) is a Fab-Fragment of a recombinant, humanized, monoclonal VEGF (anti-vascular endothelial growth factor) antibody. This study analyzed the ability of topical Ranibizumab to inhibit lymphangiogenesis in addition to hemangiogenesis after acute corneal inflammation in vivo. In addition, the effect of Ranibizumab on the proliferation of human lymphatic endothelial cells (LECs) and blood endothelial cells (BECs) in vitro was studied. METHODS The inhibitory effect of Ranibizumab on LECs and BECs was studied in vitro using a proliferation enzyme-linked immunosorbent assay (ELISA) assay. To study the in vivo effects of Ranibizumab, the mouse model of suture induced inflammatory corneal neovascularization was used. Study mice received topical Ranibizumab as eye drops. After 1 week excised corneas were stained with LYVE-1 and CD31. Hemangiogenesis and lymphangiogenesis were analyzed morphometrically by using a semiautomatic method based on the image analyzing program Cell^F. RESULTS An antiproliferative effect of Ranibizumab was seen in vitro on both human BECs and LECs with a significance of p < 0.0001 and p < 0.0004, respectively. In vivo experiments showed that topical application of Ranibizumab significantly inhibits both hemangiogenesis (p = 0.0026) and lymphangiogenesis (p = 0.0026) in the cornea. CONCLUSION Ranibizumab is a potent inhibitor of inflammatory corneal hemangiogenesis and lymphangiogenesis in vivo with a direct inhibitory effect on both endothelial cell types in vitro. This study for the first time demonstrates an inhibitory effect of Ranibizumab on lymphatic vessels which could have a wider range of clinical applications.

Abstract
We performed a study of the two clinical entities with a differential diagnosis with wet age-related macular degeneration, namely, idiopathic polypoidal choroidal vasculopathy (IPCV) and retinal angiomatous proliferation. We analyze the clinical and funduscopic characteristics of these entities as well as their differences with wet age-related macular degeneration. We present two cases that are representative of these two entities. The therapeutic possibilities, results and the latest publications are analyzed and compared. A statistical analysis of the latest publications is also presented.

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

Abstract
PURPOSE To compare treatment outcomes of photodynamic therapy (PDT), anti-vascular endothelial growth factor (VEGF) therapy and PDT combined with anti-VEGF therapy for polypoidal choroidal vasculopathy (PCV). PROCEDURES A total of 62 eyes of 62 patients who had completed at least 2 years of follow-up were retrospectively reviewed; 19 eyes received PDT only, 23 had anti-VEGF therapy only and 20 underwent combination therapy. Best-corrected visual acuity at baseline and each follow-up visit was investigated as a primary outcome measure. RESULTS At year 2, the PDT and combination groups maintained significant visual improvement (p = 0.041 and p = 0.021), whereas the anti-VEGF group failed to do so (p = 0.673) when compared with the baseline. The combination group showed better visual outcome during follow-up, and significantly better visual outcome than the PDT group (p = 0.038) and the anti-VEGF group (p = 0.012) at year 2. CONCLUSIONS Combination therapy leads to significantly better visual outcome than PDT and anti-VEGF monotherapy and is therefore a superior method for treating PCV, with a favorable visual outcome.

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

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

Abstract
PURPOSE To evaluate the 5-year efficacy of photodynamic therapy (PDT) in patients with polypoidal choroidal vasculopathy (PCV). DESIGN Retrospective study. METHODS Forty-two eyes of 36 patients with PCV followed up for at least 60 months after PDT were reviewed. All eyes were primarily treated with PDT. Main outcome measure was best-corrected visual acuity (BCVA; logMAR [logarithm of minimal angle of resolution]) at baseline and at each follow-up visit. We also classified the eyes into 3 groups: improved (improvement ≥0.3 logMAR), decreased (deterioration ≥0.3 logMAR), and stable. RESULTS During the mean follow-up duration, 73.64 ± 13.47 months, the mean number of PDT was 2.21 ± 1.62 treatments. Recurrence was noted in 33 eyes (78.6%) during follow-up. The mean baseline BCVA was 0.78 ± 0.48 logMAR (20/120 Snellen equivalent), and the final BCVA at 60 months was 0.67 ± 0.52 logMAR (20/93 Snellen equivalent) (P = .050, paired t test). On the final evaluation at 60 months, the mean BCVA was improved in 14 eyes (33.3%), stable in 23 eyes (54.8%), and decreased in 5 eyes (11.9%). CONCLUSION At 60 months after initial PDT, 88.1% of PCV patients showed stable or improved BCVA after PDT. Despite a high recurrence rate, PDT remained effective for 5 years, and represents a good therapeutic approach to PCV.

Abstract
Data on the epidemiology and treatment of age-related macular degeneration (AMD) in Asian populations have been scarce. Recently, significant advances in the current knowledge of AMD in Asia have been made, but deficiencies in important areas remain. Epidemiological data on AMD in those 80 years or older are lacking.There are also few incidence data on AMD or polypoidal choroidal vasculopathy (PCV), an important variant of AMD that seems to be more common in Asia. The risk factors for PCV have not been clearly defined to the extent that those for AMD have. No trials of nutritional supplementation for AMD prevention in Asia exist, and there is also a lack of long-term clinical trial data on combination therapy for PCV and indeed very few trial data on PCV. These represent opportunities for future research. With aging populations in Asia, increased data on the prevalence, risk factors, prevention, and treatment of AMD and PCV in Asian populations will be needed to formulate evidence-based public health and clinical guidelines.

Abstract
PURPOSE To compare the long-term results of the efficacy of photodynamic therapy (PDT) with or without intravitreal bevacizumab (IVB) injections for polypoidal choroidal vasculopathy. DESIGN Retrospective, comparative, interventional case series. METHODS We included 69 eyes of 69 patients with macula-involved polypoidal choroidal vasculopathy. All patients were followed up for more than 2 years. We compared the treatment outcomes between groups and investigated the factors influencing visual improvement at 24 months of follow-up. RESULTS Thirty-six patients received PDT combined with IVB and 33 patients received PDT monotherapy. At 3 months, the mean logarithm of minimal angle of resolution (logMAR) best-corrected visual acuity (BCVA) improved from 0.73 to 0.53 in the combined therapy group (P < .001) and from 0.79 to 0.72 in the PDT monotherapy group (P = .02), with a significant difference in treatment efficacy between the 2 groups (P < .001). However, the improvements in BCVA were not statistically significant after 21 months in the combined therapy group and 15 months in the monotherapy group. The difference in treatment efficacy between the 2 groups was not significant after 6 months. Initial BCVA (P = .005), lesion size (P = .011), patient age (P = .018), and location of polyps (P = .006) significantly predicted the final visual outcome rather than treatment modality (P = .243). CONCLUSIONS PDT combined with IVB for symptomatic PCV was temporarily superior to PDT monotherapy, and the treatment efficacy decreased with time. Initial BCVA, lesion size, and location were more significant than treatment modality as the factors influencing final visual improvement.

Abstract
Purpose We evaluated the 2-year efficacy of combined intravitreal ranibizumab (IVR) treatment and photodynamic therapy (PDT) for treatment-naïve polypoidal choroidal vasculopathy (PCV). Patients and methods Twenty-two eyes of 22 Japanese patients with treatment-naïve PCV were prospectively recruited. All eyes had angiographic features of PCV according to indocyanine green angiography. The initial combination treatment regimen included a session of PDT with IVR. A total of three consecutive IVR treatments were given at 4-week intervals. Eyes were retreated with IVR or PDT at specific times. We evaluated the mean visual acuity and mean central retinal thickness (CRT) at 3, 6, 9, 12, 18, and 24 months after initial treatment. Results At month 9, visual acuity had improved by 5.7 letters (P = 0.10). Subsequently, mean visual acuity gradually decreased, and the difference from baseline was diminished to 2.9 letters at 24 months (P = 0.43). Mean CRT was significantly decreased from baseline over the 24-month follow-up (P < 0.05). Conclusion With PDT combined with IVR for PCV, visual acuity improved during year 1, but the benefit decreased in year 2.
