The LIGHTSITE III study evaluated multiwavelength photobiomodulation (PBM) therapy in nonexudative (dry) age-related macular degeneration (AMD) using the LumiThera Valeda Light Delivery System.
LIGHTSITE III is a randomized, controlled trial to assess the safety and effectiveness of PBM in dry AMD. Subjects were given multiwavelength PBM (590, 660, and 850 nm) or Sham treatment delivered in a series of nine sessions over 3 to 5 weeks every four months over 24 months. Subjects were assessed for efficacy and safety outcomes. Data from the 13-month analysis are presented in this report.
A total of 100 subjects (148 eyes) with dry AMD were randomized. LIGHTSITE III met the primary efficacy best-corrected visual acuity endpoint with a significant difference between PBM (n = 91 eyes) and Sham (n = 54 eyes) groups (Between group difference: 2.4 letters (SE 1.15), CI: -4.7 to -0.1, P = 0.02) (PBM alone: 5.4 letters (SE 0.96), CI: 3.5 to 7.3, P < 0.0001; Sham alone: 3.0 letters (SE 1.13), CI: 0.7-5.2, P < 0.0001). The PBM group showed a significant decrease in new onset geographic atrophy ( P = 0.024, Fisher exact test, odds ratio 9.4). A favorable safety profile was observed.
LIGHTSITE III provides a prospective, randomized, controlled trial showing improved clinical and anatomical outcomes in intermediate dry AMD following PBM therapy.
LIGHTSITE III研究使用LumiThera Valeda光传递系统评估了多波长光生物调节(PBM)疗法在非渗出性(干性)年龄相关性黄斑变性(AMD)中的效果。
LIGHTSITE III是一项随机对照试验,旨在评估PBM在干性AMD中的安全性和有效性。受试者接受多波长PBM(590、660和850纳米)或假治疗,每四个月进行一系列共九次治疗,为期3至5周,持续24个月。对受试者进行疗效和安全性评估。本报告呈现了13个月分析的数据。
共有100名干性AMD受试者(148只眼)被随机分组。LIGHTSITE III达到了主要疗效最佳矫正视力终点,PBM组(n = 91只眼)和假治疗组(n = 54只眼)之间存在显著差异(组间差异:2.4个字母(标准误1.15),置信区间:-4.7至-0.1,P = 0.02)(单独PBM:5.4个字母(标准误0.96),置信区间:3.5至7.3,P < 0.0001;单独假治疗:3.0个字母(标准误1.13),置信区间:0.7 - 5.2,P < 0.0001)。PBM组新发地图样萎缩显著减少(P = 0.024,Fisher精确检验,优势比9.4)。观察到良好的安全性。
LIGHTSITE III提供了一项前瞻性、随机、对照试验,表明PBM治疗后中度干性AMD的临床和解剖学结果得到改善。
