Abstract
The use of anti-vascular endothelial growth factor (VEGF) agents has profoundly changed the prognosis of neovascular age-related macular degeneration (nAMD). As clinical experiences have accumulated, it has become mandatory to summarize data to give information that can be useful in everyday practice. We conducted a systematic review to identify randomized controlled trials (RCTs) and observational studies that reported 12-month changes in best-corrected visual acuity (BCVA) in patients with nAMD on anti-VEGF monotherapy. Data were analyzed in a random-effects meta-analysis with BCVA change as the primary outcome. Meta-regression was conducted to evaluate the impact of multiple covariates. Four hundred and twelve heterogeneous study populations (109,666 eyes) were included. Anti-VEGFs induced an overall improvement of +5.37 ETDRS letters at 12 months. Meta-regression showed that mean BCVA change was statistically greater for RCTs (p = 0.0032) in comparison with observational studies. Populations following a proactive regimen had better outcomes than those following a reactive treatment regimen. Mean BCVA change was greater in younger populations, with lower baseline BCVA and treated with a higher number of injections (p < 0.001). Our results confirm that anti-VEGFs may produce a significant functional improvement at 12 months in patients with nAMD.

Abstract
BACKGROUND The effect of ALS-L1023, an extract of Melissa officinalis L. (Labiatae; lemon balm) leaves, on experimental choroidal neovascularization (CNV) in mice was evaluated. METHODS C57BL/6 mice were given either vehicle or ALS-L1023 daily via oral gavage for 3 weeks (days 0-21). CNV was induced by rupturing Bruch's membrane using laser photocoagulation (day 7). Two weeks after laser injury (day 21), the CNV lesions were evaluated by an examination of choroidal flat mounts using fluorescein-labelled dextran, immunofluorescence staining with isolectin B4 and fluorescence angiography. The effects of ALS-L1023 on endothelial cell tube formation and the expression of phosphorylated extracellular signal-regulated kinase 1/2 were evaluated using human umbilical vein endothelial cells. RESULTS The extent of CNV was reduced by ALS-L1023. Mice treated with 100 and 200 mg/kg/day of the material exhibited 44.3 and 68.1% reductions in the extent of CNV lesions, respectively, compared to the vehicle group (P < 0.001). The size of the isolectin B4-labelled area was also significantly decreased in the ALS-L1023-treated groups (P < 0.001). On fluorescein angiography, ALS-L1023-treated mice exhibited significantly less leakage of fluorescent material than did vehicle-treated mice. ALS-L1023 decreased vascular endothelial growth factor-induced human umbilical vein endothelial cell tube formation in a dose-dependent manner. The expression of phosphorylated extracellular signal-regulated kinase 1/2 was suppressed by ALS-L1023. CONCLUSIONS The laser-induced CNV in mice can be inhibited by ALS-L1023. Therefore, it may have therapeutic potential for the treatment of diseases involving CNV.

A prospective study of treatment patterns and 1-year outcome of Asian age-related macular degeneration and polypoidal choroidal vasculopathy. PLoS One 2014; 9:e101057. [PMID: 24978485 PMCID: PMC4076260 DOI: 10.1371/journal.pone.0101057] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2013] [Accepted: 06/02/2014] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE To study the treatment patterns and visual outcome over one year in Asian patients with choroidal neovascular membrane secondary to age-related macular degeneration (AMD-CNV) and polypoidal choroidal vasculopathy (PCV). DESIGN Prospective cohort, non-interventional study. METHODS 132 treatment-naïve patients who received treatment for AMD-CNV and PCV were included. All patients underwent standardized examination procedures including retinal imaging at baseline and follow-up. AMD-CNV and PCV were defined on fundus fluorescein angiography and indocyanine green angiography at baseline. Patients were treated according to standard of care.We report the visual acuity (VA) and optical coherence tomography (OCT) measurements at baseline, month 3 and month 12 The factors influencing month 12 outcomes were analyzed. MAIN OUTCOME MEASURE Type of treatment, number of Anti-vascular endothelial growth factor (VEGF) treatments, visual outcome over one year. RESULTS Anti-VEGF monotherapy was the initial treatment in 89.1% of AMD-CNV, but only 15.1% of PCV. The mean number of anti-VEGF injections up to month 12 was 3.97 (4.51 AMD-CNV, 3.43 PCV, p = 0.021). Baseline OCT, month 3 OCT and month 3 VA were significant in determining continuation of treatment after month 3. At month 12, mean VA improved from 0.82 (∼20/132) at baseline to 0.68 (∼20/96) at month 12 (mean gain 6.5 ETDRS letters, p = 0.002). 34.2% of eyes (38/113 eyes) gained ≥15 ETDRS letters and 14.4% (16/113 eyes) lost ≥15 ETDRS letters. There were no significant differences in visual outcome between AMD-CNV and PCV (p = 0.51). Factors predictive of month 12 visual outcome were baseline VA, baseline OCT central macular thickness, month 3 VA and age. CONCLUSIONS There is significant variation in treatment patterns in Asian eyes with exudative maculopathy. There is significant visual improvement in all treatment groups at one year. These data highlight the need for high quality clinical trial data to provide evidence-based management of Asian AMD.

Influence of ranibizumab treatment on the extracellular matrix in patients with neovascular age-related macular degeneration. Med Sci Monit 2014; 20:875-83. [PMID: 24866589 PMCID: PMC4049949 DOI: 10.12659/msm.890031] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2013] [Accepted: 12/13/2013] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND We know the influence of the intravitreal anti-vascular endothelial growth factor (VEGF) injections on the choroidal neovascularization in the course of exudative age-related macular degeneration (AMD). However, the influence of the ranibizumab therapy in question on the extracellular matrix (ECM) remains unknown. We aimed to estimate the influence of Lucentis intravitreal injections on the gene expression of structural components of the extracellular matrix in patients with neovascular AMD. MATERIAL AND METHODS Patients with subfoveal localization of neovascularization in AMD, which was clinically active and observed using optical coherence tomography, were treated with ranibizumab (0.5 mg/0.05 mL) in accordance with the PrONTO scheme. Total RNA was extracted from peripheral blood mononuclear cells, and an oligonucleotide microarray technique enabled comparison of the expression level of genes encoding collagens, elastin, and laminins in AMD patients compared to control subjects. RESULTS After 3 intravitreal injections of ranibizumab (Lucentis), COL1A1 and COL6A1 genes showed increased expression, whereas decreased expression mainly occurred for the following genes: COL4A5, COL11A1, OL4A6C, LAMB4, and LAMC2. CONCLUSIONS Anti-VEGF local therapy influences the gene expression of structural components of the ECM as measured from blood samples. The loading dose of ranibizumab for the retina changes the expression of collagen and laminin genes, but does not influence the expression of the elastin gene.

Abstract
Age-related macular degeneration (AMD) is the leading cause of visual loss in older population. Angiogenesis is an important factor associated with the development of CNV due to AMD. Treatment of CNV with intravitreal anti-VEGF monotherapy is currently the standard of care. However, not all patients respond to monotherapy, and modified anti-VEGF treatment regimen and combination therapy may target reducing treatment frequency or improving visual outcome. This paper reviews the many clinical trials that have been performed utilizing several treatment regimens. While many trials have shown that this variable therapy is justifiable, further study is required to determine correct regimens and dosage.
