The purpose of this study was to compare 6-year visual outcomes of antivascular endothelial growth factor (anti-VEGF) monotherapy and initial combination therapy of photodynamic therapy (PDT) and anti-VEGF therapy for polypoidal choroidal vasculopathy (PCV) in a Chinese population and to investigate imaging biomarkers associated with visual outcomes. Forty-eight treatment-naive PCV eyes of 46 patients were reviewed retrospectively, which underwent anti-VEGF monotherapy or initial combination therapy. PCV was classified into 2 subtypes. Mean best-corrected visual acuity (BCVA) using logarithm of minimal angle resolution and imaging morphological features was compared. No significant differences of mean BCVA changes were noticed between anti-VEGF monotherapy and combination therapy in either subtype 1 PCV or subtype 2 PCV during 6-year period (all P values >0.05). Compared with BCVA at baseline, the mean BCVA at 72 months deteriorated significantly in eyes with subtype 1 PCV (P<0.001), while the mean BCVA at 72 months remained stable in eyes with subtype 2 PCV (P=0.941). In subtype 2 PCV eyes with continuous retina pigment epithelium, the mean changes of BCVA in eyes treated with anti-VEGF monotherapy were better than those in eyes treated with combination therapy (P=0.020). Anti-VEGF monotherapy and combination therapy for various subtypes of PCV had comparable long-term visual outcomes in most cases in real world. Imaging biomarkers which correlate with visual outcomes and treatment response should be included in the classification of PCV and validated in real world.

Abstract Background To evaluate 5-year outcomes of anti-vascular endothelial growth factor (VEGF) monotherapy and combination therapy of anti-VEGF agents and photodynamic therapy (PDT) for polypoidal choroidal vasculopathy (PCV) in a real-world Chinese population. Methods Retrospective study. Fifty-three eyes of 46 patients with subtype 1 and 2 PCV followed up for at least 60 months were grouped into three regimens: anti-VEGF monotherapy, PDT combining with anti-VEGF therapy initially, and PDT combining with deferred anti-VEGF therapy. Main outcome measure was best-corrected visual acuity (BCVA) using logarithm of minimal angle of resolution (logMAR). Results The mean BCVA of eyes with subtype 1 PCV (n = 28) deteriorated from 0.69 logMAR at baseline to 1.25 logMAR at months 60 (P = 0.001), while the mean BCVA of eyes with subtype 2 PCV (n = 25) sustained stable from 0.62 logMAR at baseline to 0.57 at months 60 (P = 0.654). No significant differences of visual outcomes were found between the 3 treatment regimens for subtype 1 PCV. Anti-VEGF monotherapy and initial combination treatment had better visual outcomes in eyes with subtype 2 PCV than deferred combination group during part of follow-up significantly. Initial combination group needed a less number of PDT than deferred combination group (P < 0.001). Conclusions Compared with subtype 1 PCV, subtype 2 PCV has a more favorable visual outcome in real world. All the regimens presented unfavorable visual outcomes for subtype 1 PCV. Anti-VEGF monotherapy and initial combination therapy should be superior to deferred combination therapy in the long-term management of subtype 2 PCV. Prospective randomized studies of larger size are needed to determine the long-term efficacy and safety of various treatment for PCV in real world.

This multicenter retrospective study was conducted to evaluate the 1-year treatment outcome of photodynamic therapy (PDT) combined with anti-vascular endothelial growth factor (VEGF) therapy for pachychoroid neovasculopathy (PNV). A total of 42 eyes of 42 patients with treatment-naïve PNV who were treated with PDT combined with intravitreal injections of an anti-VEGF agent (ranibizumab or aflibercept) for 1 year. All eyes showed exudative and/or hemorrhagic changes that affected the fovea at baseline. After the initial combination therapy, subfoveal choroidal thickness (SCT) and central retinal thickness (CRT) were significantly reduced and were maintained as such for 12 months (P < 0.01 in SCT and CRT). The best-corrected visual acuity (BCVA) (0.19 ± 0.30 at baseline) significantly improved at 3 months (0.15 ± 0.29, P < 0.05) and further improved at 12 months (0.10 ± 0.30, P < 0.01) when compared to that at baseline. After the initial combination therapy, 32 eyes (76.2%) required no additional treatments for 12 months. The mean number of additional PDT and intravitreal injections of anti-VEGF agents was 0.1 ± 0.3 and 0.9 ± 1.9, respectively. Of the 42 eyes included in this study, 22 eyes (52.4%) had polypoidal lesions at baseline. No significant differences in SCT, CRT, or BCVA were observed at any time points between eyes with and without polypoidal lesions. Of 20 eyes without polypoidal lesions, only 1 eye (5.0%) needed additional treatments. PNV, especially without polypoidal lesions, can be treated effectively with PDT combined with anti-VEGF therapy with few sessions.

Background/aimsTo describe the risk factors for the development of retinal pigment epithelial (RPE) atrophy following intravitreal anti-vascular endothelial growth factor (VEGF) injection treatment for polypoidal choroidal vasculopathy (PCV).MethodsWe retrospectively included 162 eyes of 162 treatment-naïve patients with PCV in this study. All patients were treated with an initial series of three monthly loading doses of anti-VEGF injections, followed by further injections as required. Baseline ocular characteristics and lesion features were assessed using fluorescein angiography, indocyanine green angiography and spectral domain optical coherence tomography, to determine and evaluate the potential risk factors for RPE atrophy through 2 years of follow-up.ResultsRPE atrophy had developed in 17 of 162 eyes (10.5%) after 2 years of anti-VEGF treatment. Nine cases (53.0%) of RPE atrophy occurred at branching vascular networks, and eight (47.0%) developed at locations with polyp or polyp-associated pigment epithelial detachment. Among the baseline characteristics, the mean subfoveal choroidal thickness was significantly thinner (192±98 vs 288±152; p=0.009) and presence of subretinal drusenoid deposits was significantly more frequent in eyes with RPE atrophy (11.8% vs 2.1%; p=0.028). Using multiple logistic regression analysis, the mean subfoveal choroidal thickness (OR 0.975; 95% CI 0.929 to 1.324; p=0.002) was identified as a significant risk factor for the development of RPE atrophy.ConclusionsApproximately one-tenth of the patients with PCV developed RPE atrophy during the 24 months after intravitreal anti-VEGF injections. Subfoveal choroidal thinning at baseline is associated with increased risk of post-treatment RPE atrophy.

ObjectiveTo evaluate the 6-year outcomes of anti-VEGF (vascular endothelial growth factor) monotherapy for polypoidal choroidal vasculopathy (PCV).MethodsThe charts of 66 eyes of 66 patients with newly diagnosed, symptomatic, treatment-naive PCV were reviewed retrospectively. All patients were treated with 0.5 mg intravitreal ranibizumab (IVR) injections for 3 months followed by as-needed reinjections based on monthly examinations until 3 years after the first IVR injection. Thereafter, anti-VEGF monotherapy was continued for another 3 years.ResultsThe mean best-corrected visual acuity (BCVA) improved significantly (p=0.001) 3 months after the first IVR injection (0.24±0.30 logarithm of the minimum angle of resolution (logMAR) VA; 20/35 Snellen VA) compared with the baseline BCVA (0.34±0.37 logMAR VA; 20/44 Snellen VA). However, the improved VA returned to 0.32±0.39 logMAR unit (20/42 Snellen VA), which was not significantly different at 3 years. This level was maintained to the end of 6 years (0.36±0.37 logMAR unit; 20/46 Snellen VA). The mean numbers of anti-VEGF injections administered annually during 6 years were 5.6±2.4 (including the initial three monthly injections), 3.3±2.2, 3.3±2.9, 3.6±3.2, 3.5±2.9 and 3.3±2.7, respectively. The mean total number of injections during 6 years was 21.5±10.1.ConclusionsThe results emphasised the efficacy of anti-VEGF therapy for preserving vision and the limitations of anti-VEGF therapy in that continuous treatment is required over an extended follow-up period.

AbstractPolypoidal choroidal vasculopathy (PCV) is a vision-threatening disease common in Asian populations. However, the optimal treatment for PCV remains under debate. We searched the databases with optimal searching strategy. The study included randomized clinical trials and prospective studies that recruited patients with active PCV who had received interventions, including PDT, anti-VEGF, or a combination of PDT and anti-VEGF. The Grading of Recommendations Assessment, Development, and Evaluation methodology was used for rating the quality of evidence. Our study included 11 studies involving 1277 patients. The network meta-analysis of RCTs revealed the anti-VEGF group, early combination group, and late combination group had significant BCVA changes compared with the PDT group. Early combination therapy led to a significant decrease in CRT compared with PDT, anti-VEGF, and late combination therapy. Additionally, the early combination group had a significantly higher complete polyp regression rate than the anti-VEGF group. No significant differences were detected in the analysis of the number of anti-VEGF injections and safety profile. This network meta-analysis revealed that early combination therapy exhibited better efficacy related to anatomical outcomes than other therapies. Nonetheless, no significant differences related to BCVA change could be detected between anti-VEGF and late combination therapy.

Previous studies based on clinical trial data have demonstrated that greater fluctuations in retinal thickness during the course of intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy for neovascular age-related macular degeneration (nAMD) is associated with poorer visual acuity outcomes. However, it was unclear whether similar findings would be observed in real-world clinical settings. This study aimed to evaluate the association between retinal thickness variability and visual outcomes in eyes receiving anti-VEGF therapy for nAMD using pro re nata treatment regimen. A total of 64 eyes which received intravitreal anti-VEGF therapy (bevacizumab, ranibizumab or aflibercept) for the treatment of nAMD were evaluated. Variability in spectral-domain optical coherence tomography (OCT) central subfield thickness (CST) was calculated from the standard deviation (SD) values of all follow-up visits after three loading doses from month 3 to month 24. Eyes were divided into quartiles based on the OCT CST variability values and the mean best-corrected visual acuity values at 2 years were compared. At baseline, the mean ± SD logMAR visual acuity and CST were 0.59 ± 0.39 and 364 ± 113 µm, respectively. A significant correlation was found between CST variability and visual acuity at 2 years (Spearman’s ρ = 0.54, p < 0.0001), indicating that eyes with lower CST variability had better visual acuity at 2 years. Eyes with the least CST variability were associated with the highest mean visual acuity improvement at 2 years (quartile 1: +9.7 letters, quartile 2: +1.1 letters, quartile 3: −2.5 letters, quartile 4: −9.5 letters; p = 0.018). No significant difference in the number of anti-VEGF injections was found between the four CST variability quartile groups (p = 0.21). These findings showed that eyes undergoing anti-VEGF therapy for nAMD with more stable OCT CST variability during the follow-up period were associated with better visual outcomes. Clinicians should consider adopting treatment strategies to reduce CST variability during the treatment course for nAMD.
