研究目的: |
本研究拟探究角膜基质注射阿柏西普对活动期及稳定期角膜新生血管疗效差异,同时探索优化角膜基质注射阿柏西普治疗时间点及可能机制,为不同阶段患者提供精确化治疗方案,并为阿柏西普临床应用提循证依据。 |

Objectives of Study: |
This study aims to investigate the difference in efficacy of aflibercept injection into the corneal stroma for corneal neovascularization during active and stable phases, while also exploring the optimization of the timing and possible mechanisms of aflibercept injection into the corneal stroma, providing precise treatment plans for patients at different stages, and offering evidence-based support for the clinical application of aflibercept. |
||||||||||||||||||||||
|
药物成份或治疗方案详述: |
所有受试者均接受基础抗炎治疗(如糖皮质激素类药物点眼),在标准治疗基础上,比较不同注射时序的疗效差异。角膜基质注射阿柏西普均由同一人在手术显微镜下进行精细操作,注射前患者均签署知情同意书。注射前行表面麻醉,开睑器开睑,用29 G胰岛素注射器距角膜新血管灶边缘1mm的角膜组织3~4个点,尽量避开瞳孔区,紧邻病灶边缘相对健康角膜,针尖指向病灶,针头平行刺入角膜基质层内,约与角膜表面成15°,深达1/2角膜厚度,沿角膜弧度潜行至新生血管区,缓慢注入药物。每个点注射阿柏西普0.02~0.03ml,至周围基质水化变白,退出针头,轻压针孔30 s防止药液外渗。总注射剂量不超过0.1 ml。注射后以左氧氟沙星眼用凝胶涂眼并包眼,其后1周内予以左氧氟沙星滴眼液滴眼,4次/d,左氧氟沙星眼用凝胶涂眼,每晚1次。 |

Description for medicine or protocol of treatment in detail: |
All subjects received basic anti-inflammatory treatment (such as glucocorticoid drug eye drops). On the basis of standard treatment, the efficacy of different injection sequences was compared. Corneal stromal injection of aflibercept was performed by the same person under the operating microscope. All patients signed the informed consent before injection. Using a 29 G insulin syringe, 3 to 4 points were placed in the corneal tissue 1mm from the edge of the corneal new blood vessel focus. The pupil area was avoided as far as possible. The needle tip was pointed at the focus, and the needle was inserted parallel into the corneal stromal layer, about 15° from the corneal surface, with a depth of 1/2 corneal thickness. The drug was slowly injected by sneaking along the curvature of the cornea to the neovascularization area. Aflibercept 0.02-0.03 ml was injected into each point until the surrounding matrix was hydrated and white, the needle was withdrawn, and the needle hole was gently pressed for 30 s to prevent extravasation of the drug solution. The total injection dose did not exceed 0.1 ml. After the injection, levofloxacin eye gel was applied and covered, and then levofloxacin eye drops were given 4 times a day, and levofloxacin eye gel was applied once a night for 1 week. |

随机方法(请说明由何人用什么方法产生随机序列): |
由独立第三方统计师采用分层区组随机化方法,按研究中心和CNV疾病阶段(活动期/稳定期)进行分层,使用计算机随机数生成器产生区组长度为4的随机序列,按1:1:1:1比例将受试者分配至活动期组早期干预亚组、活动期组延迟干预亚组、稳定期组早期干预亚组和稳定期组延迟干预亚组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
An independent third-party statistician used a stratified block randomization method, stratified by study center and CNV disease stage (active/stable phase), and generated a random sequence with a block length of 4 using a computer random number generator to assign subjects to the early intervention subgroup of the active group , delayed intervention subgroup of the active group , early intervention subgroup of the stable group , and delayed intervention subgroup of the stable group in a 1:1:1:1 ratio. |
