Anti-vascular endothelial growth factor monotherapy or combined with verteporfin photodynamic therapy for retinal angiomatous proliferation: a systematic review with meta-analysis. Front Pharmacol 2023; 14:1141077. [PMID: 37377929 PMCID: PMC10291099 DOI: 10.3389/fphar.2023.1141077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 05/19/2023] [Indexed: 06/29/2023] Open
Abstract
Purpose: To assess functional and anatomical outcomes of intravitreal anti-Vascular Endothelial Growth Factor (anti-VEGF) monotherapy versus combined with verteporfin Photodynamic Therapy (PDT) for Retinal Angiomatous Proliferation (RAP). Methods: Studies reporting outcomes of intravitreal anti-VEGF monotherapy and/or in combination with verteporfin PDT in RAP eyes with a follow-up ≥ 12 months were searched. The primary outcome was the mean change in best corrected visual acuity (BCVA) at 12 months. Mean change in central macular thickness (CMT) and mean number of injections were considered as secondary outcomes. The mean difference (MD) between pre- and post-treatment values was calculated along with 95% Confidence Interval (95% CI). Meta-regressions were performed to assess the influence of anti-VEGF number of injections on BCVA and CMT outcomes. Results: Thirty-four studies were included. A mean gain of 5.16 letters (95% CI = 3.30-7.01) and 10.38 letters (95% CI = 8.02-12.75) was shown in the anti-VEGF group and combined group, respectively (anti-VEGF group vs. combined group, p < 0.01). A mean CMT reduction of 132.45 µm (95% CI = from -154.99 to -109.90) and 213.93 µm (95% CI = from -280.04 to -147.83) was shown in the anti-VEGF group and combined group, respectively (anti-VEGF group vs. combined group, p < 0.02). A mean of 4.9 injections (95% CI = 4.2-5.6) and 2.8 injections (95% CI = 1.3-4.4) were administered over a 12-month period in the anti-VEGF group and combined group, respectively. Meta-regression analyses showed no influence of injection number on visual and CMT outcomes. High heterogeneity was found across studies for both functional and anatomical outcomes. Conclusion: A combined approach with anti-VEGF and PDT could provide better functional and anatomical outcomes in RAP eyes compared with anti-VEGF monotherapy.

Two-year clinical outcomes of triple therapy with photodynamic therapy, anti-vascular endothelial growth factor agent, and triamcinolone acetonide for neovascular age-related macular degeneration. Jpn J Ophthalmol 2023; 67:50-58. [PMID: 36346553 DOI: 10.1007/s10384-022-00955-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 09/22/2022] [Indexed: 11/10/2022]
Abstract
PURPOSE To analyze the 2-year treatment outcomes of triple therapy with standard-fluence photodynamic therapy (PDT), intravitreal injection of ranibizumab (IVR)/aflibercept (IVA), and sub-tenon injection of triamcinolone acetonide (STTA) for neovascular age-related macular degeneration (nAMD) in Japanese patients. STUDY DESIGN A retrospective, clinical case-series study. METHODS Forty-four eyes of 44 patients with treatment-naïve nAMD followed for more than 24 months were evaluated. Initial treatment was given with triple therapy and retreatment with IVR/IVA as a pro re nata regimen. Best-corrected visual acuity (BCVA), central retinal thickness (CRT), the number of treatments, and intraocular pressure elevation were analyzed. RESULTS The mean age was 73.3 ± 10.0 years. The mean BCVA significantly improved from 0.61 ± 0.30 at baseline to 0.50 ± 0.46 at 24 months (p = 0.034). CRT significantly improved from 373 ± 162 μm at baseline to 200 ± 107 μm at 24 months (p < 0.001). The number of treatments given during the 2-year treatment period was 2.7 ± 1.8. No retreatments were necessary in 18 of 44 eyes (40.9%), with no significant difference between IVR (46.4%) or IVA (31.3%) used during the 2-year follow-up of triple therapy (p = 0.51). Four eyes (9.1%) temporarily required glaucoma eye drop treatments. CONCLUSION In nAMD patients, induction treatment with triple therapy resulted in approximately 40% of the patients requiring no retreatment for 2 years. The type of anti-VEGF agents used made no difference in the results.

Kim JH, Kim JW, Kim CG. Comparison of 24-month treatment outcomes between as-needed treatment and switching to treat-and-extend in type 3 macular neovascularization. Sci Rep 2022; 12:22546. [PMID: 36581675 PMCID: PMC9800385 DOI: 10.1038/s41598-022-25860-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Accepted: 12/06/2022] [Indexed: 12/31/2022] Open
Abstract
This study aimed to compare 24-month treatment outcomes between patients with type 3 macular neovascularization (MNV) treated using an as-needed regimen and those who switched to treat-and-extend (TAE). This retrospective study included 32 patients who were initially treated with an as-needed regimen but switched to TAE (TAE group) and 74 patients who were treated with an as-needed regimen throughout the follow-up period (as-needed group). The number of anti-vascular endothelial growth factor (VEGF) injections and degree of change in best-corrected visual acuity (BCVA) over 24 months were compared between the two groups. The incidence of fibrotic scarring, tears of the retinal pigment epithelium (RPE), and subretinal hemorrhage was also evaluated. The number of anti-VEGF injections was higher in the TAE group (mean: 11.7) than in the as-needed group (mean: 6.9; P < 0.001). The BCVA outcome (measured using the mean logarithm of the minimal angle of resolution [logMAR]) was significantly better in the TAE group (mean improvement of logMAR 0.15) than in the as-needed group (mean deterioration of logMAR 0.15). The incidence of fibrotic scarring (6.3% vs. 18.9%), RPE tears (3.1% vs. 6.8%), and subretinal hemorrhage (0% vs. 9.5%) was relatively lower in the TAE group. Treatment outcomes of the TAE group were better than those of the as-needed group, suggesting that switching to the TAE regimen would be a useful approach for patients with type 3 MNV requiring efficient treatment.

Abstract
PURPOSE To compare lesion reactivation and treatment outcomes between pure type 2 and mixed type 1 and 2 macular neovascularization (MNV) treated with anti-vascular endothelial growth factor (VEGF). METHODS This retrospective study included 155 patients diagnosed with type 2 MNV. After the initial loading injections, as-needed retreatment was provided. The difference in first lesion reactivation after the initial treatment was evaluated between pure type 2 MNV (pure type 2 group, n = 37) and mixed type 1 and 2 MNV (mixed group, n = 118). The degree of change in the best-corrected visual acuity (BCVA) was also compared between the two groups. RESULTS The mean follow-up period was 32.7 ± 13.7 months. Lesion reactivation differed significantly between the type 2 (60.0%) and mixed (84.5%) (P = .004) groups. The degree of visual change during the follow-up period also differed significantly between the pure type 2 (mean 2.8 lines of improvement) and mixed (mean 0.2 lines of deterioration) (P = .008) groups. In multivariate analysis, lesion type (P = .012) and baseline visual acuity (P = .002) were significantly associated with ≥2 lines of visual improvement. CONCLUSIONS Lesion reactivation and treatment outcomes differed between pure type 2 and mixed type 1 and 2 MNV. These results suggested the need for different treatment strategies for these two MNV subtypes.

Abstract
PURPOSE To investigate the incidence, risk factors, and their influence on visual outcomes of subretinal hemorrhage (SRH) in patients with neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy(PCV) who discontinue treatment. METHODS This retrospective study included 148 patients with nAMD and PCV who discontinued treatment. The development of a 3-disc area or greater extent of SRH after treatment discontinuation was identified. Visual acuity at the final visit was compared between patients with and those without SRH. Factors associated with SRH were then analyzed. RESULTS During the mean 56.8 ± 18.2 months of follow-up, treatment was discontinued at a mean 24.1 ± 16.3 months after diagnosis. SRH developed in 24 (16.2%) patients at a mean 21.5 ± 17.6 months after treatment discontinuation. The visual acuity at the final follow-up was significantly worse in patients with SRH than in those without SRH (P < 0.001). There was a significant difference in the incidence of SRH among the different types of macular neovascularization (MNV) (P = 0.024). In particular, the incidence of type 3 MNV was relatively high (36.0%). CONCLUSIONS The development of SRH may lead to very poor visual prognosis in patients who discontinue treatment. The high risk of SRH in type 3 MNV suggests the need for caution when choosing treatment discontinuation in cases of type 3 MNV.

Abstract
PURPOSE The purpose of this study is to report the 24-month outcomes of a pro re nata (PRN) compared with a treat and extend (T&E) regimen in patients previously treated for neovascular age-related macular degeneration (nAMD). METHODS This was a 2-year prospective, single-center study. Previously treated patients for nAMD were randomized into two regimen groups: T&E and PRN groups. Main outcome measured was change in best corrected visual acuity (BCVA) from baseline to month 24. Secondary outcomes encompassed anatomical features such as central retinal thickness (CRT), number of intravitreal injections (IVI), and visits required. RESULTS A total of 124 eyes received the T&E (n = 61) or PRN (n = 63) regimen. At month 24, the mean BCVA change was -4.4 early treatment diabetic retinopathy study (ETDRS) letters (T&E) and -3.4 ETDRS letters (PRN), with a difference of +1.1 ETDRS letters (95% CI [-2.25]; p = 0.006). The mean change in CRT was -10.6 µm (T&E) and -7.9 µm (PRN), with a difference of +2.6 µm (95% CI [+19.2]; p = 0.004). The T&E group had received a mean of +4.6 more injections (95% CI [-7.06; -2.12]; p < 0.001) at month 24. CONCLUSION There was statistically proven non-inferiority between the PRN and T&E regimens in terms of visual and anatomical outcomes at 24 months, with significantly more IVI administered in the T&E regimen.

Abstract
PURPOSE To evaluate the difference in the treatment burden among different types of neovascular age-related macular degeneration (AMD). METHODS This retrospective, observational study included 431 patients who were diagnosed with neovascular AMD. Patients were divided into three groups: type 1 or 2 neovascularization group (n = 167), type 3 neovascularization group (n = 50), and polypoidal choroidal vasculopathy (PCV) group (n = 214). The number of hospital visits per year and the number of anti-vascular endothelial growth factor (VEGF) injections per year were compared among these groups. Furthermore, the incidence of bilateral involvement during the follow-up period was compared among the groups. RESULTS The mean follow-up period was 50.6 ± 11.3 months. The number of hospital visits per year was significantly higher in the type 1 or 2 neovascularization group (mean: 6.1 ± 1.5) and type 3 neovascularization (6.6 ± 1.6) than in the PCV group (6.0 ± 1.5) (P < 0.001). The number of anti-VEGF injections per year was significantly higher in type 3 neovascularization group (3.1 ± 1.7) than in the type 1 or 2 neovascularization group (2.3 ± 1.5) or the PCV group (2.3 ± 1.2) (P = 0.042). There was a significant difference in the incidence of bilateral involvement among patients in type 1 or 2 neovascularization group (20.4%), type 3 neovascularization group (46.0%), and the PCV group (15.4%) (P < 0.001). CONCLUSIONS The high frequency of hospital visits and that of anti-VEGF injections in patients with type 3 neovascularization suggests high treatment burden in these patients. The high incidence of bilateral involvement could be one of the primary reasons for high treatment burden in patients with type 3 neovascularization.

Fibrovascular pigment epithelial detachment in eyes with subretinal hemorrhage secondary to neovascular AMD or PCV: a morphologic predictor associated with poor treatment outcomes. Sci Rep 2020; 10:14943. [PMID: 32913279 PMCID: PMC7483711 DOI: 10.1038/s41598-020-72030-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Accepted: 08/24/2020] [Indexed: 12/15/2022] Open
Abstract
To evaluate the influence of fibrovascular pigment epithelial detachment (FVPED) on treatment outcomes in eyes with subretinal hemorrhage secondary to neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV). This retrospective study included 83 eyes diagnosed with fovea-involving submacular hemorrhage secondary to neovascular AMD or PCV. All the patients were treated with intravitreal anti-vascular endothelial growth factor. Eyes showing definite FVPED, which involves the subfoveal region, were included in the FVPED group. Eyes without subfoveal PED, shallow irregular PEDs, or serous/hemorrhagic PED were stratified to the non-FVPED group. The best-corrected visual acuity (BCVA) at diagnosis, at 3 months, at 12 months, and lesion re-activation after initial treatment were compared between the two groups. The mean size of hemorrhage was 8.6 ± 7.6 disc diameter areas. In the FVPED group, the mean logarithm of minimal angle of resolution BCVA was 1.11 ± 0.49 at diagnosis, 0.89 ± 0.58 at 3 months, and 1.05 ± 0.63 at 12 months. In the non-FVPED group, the values were 0.97 ± 0.56, 0.56 ± 0.55, and 0.45 ± 0.50, respectively. The BCVA at 3 months (P = 0.036) and at 12 months (P < 0.001) was significantly worse in the FVPED group than in the non-FVPED group. In addition, the incidence of lesion reactivation was greater in the FVPED group (83.3%) than in the non-FVPED group (38.5%) (P < 0.001). The presence of subfoveal FVPED was associated with a high incidence of lesion re-activation and poor treatment outcomes in eyes with subretinal hemorrhage. This result suggests that different treatment strategies are needed between eyes with and without FVPED.

Abstract
Purpose: To evaluate the periodicity of the intervals of lesion reactivation in patients with neovascular age-related macular degeneration (AMD). Methods: This retrospective study included 139 eyes diagnosed with treatment-naive neovascular AMD and treated with antivascular endothelial growth factor (VEGF) therapy. Patients were initially treated with 3 loading anti-VEGF injections using either ranibizumab or aflibercept. Additional treatment was administered only when lesion reactivation was noted. The difference between the time intervals to the first and the second reactivations was evaluated. The included eyes were divided into 2 groups according to the time interval to the first reactivation: the early reactivation group (≤6 months, n = 86) and the late reactivation group (>6 months, n = 53). The association between the time intervals to the first and the second reactivations was evaluated within each group. Results: The mean follow-up period was 52.7 ± 8.9 months. The first reactivation was noted at mean 9.4 ± 10.4 months after the loading injections. The second reactivation was noted at mean 6.2 ± 4.9 months after the treatment for the first reactivation. The time interval to the second reactivation was significantly shorter compared with the first reactivation (P = 0.018). The association between the time interval to the first and the second reactivations was significant only in the early reactivation group (P = 0.002). Conclusions: A short first reactivation interval suggests that there is a high likelihood that the second reactivation will also be short. However, a long first reactivation interval does not suggest that the second reactivation interval will be similarly long.
