研究目的:

评价前房注射NAM治疗角膜内皮失代偿临界期患者的有效性  

Objectives of Study:

Evaluating the efficacy of intracameral injection of NAM in treating patients with corneal endothelial decompensation at the critical stage

药物成份或治疗方案详述:

本研究药物为尼克酰胺(NAM,维生素 B3 衍生物),用于前房注射治疗角膜内皮失代偿临界期患者。药品制备需在无菌条件下操作:取50mg NAM 加入80ml 平衡盐溶液(BSS)充分溶解,调节 pH 至 7.2-7.4,经滤除菌后制成浓度 5mM、无热源、等渗的注射液。 给药方式为前房注射,药物扩散后终浓度维持 5mM。注射前需穿刺抽取 50-100μL 房水(-80℃保存,用于探索性生物标志物分析)。合并用药可保留必要眼药(如 0.3% 加替沙星眼用凝胶、他克莫司眼水等)。术后按 1、7、14、30天随访,评估有效性与安全性。 

Description for medicine or protocol of treatment in detail:

The study drug is nicotinamide (NAM, a vitamin B3 derivative), intended for intracameral injection in patients with corneal endothelial decompensation at the critical stage.Drug preparation must be performed under sterile conditions:50 mg of NAM is dissolved thoroughly in 80 ml of balanced salt solution (BSS), the pH is adjusted to 7.2-7.4, and the solution is sterilized by filtration to prepare an injectable formulation with a concentration of 5 mM, pyrogen-free, and isotonic. The administration route is intracameral injection, and the final concentration of the drug is maintained at 5 mM after diffusion.Prior to injection, 50-100 μL of aqueous humor is aspirated by puncture (stored at -80℃ for exploratory biomarker analysis).Concomitant medications may include necessary ophthalmic drugs (e.g., 0.3% gatifloxacin ophthalmic gel, tacrolimus ophthalmic solution, etc.).Postoperative follow-up visits are scheduled at 1, 7, 14, and 30 days to assess efficacy and safety.  

纳入标准:

年龄 ≥ 18岁。 临床确诊为角膜内皮失代偿临界状态,伴有持续性角膜水肿。 研究眼CCT ≥ 620 μm 或较对侧健眼增厚 >50 μm。 研究眼BCVA为眼前手动 ~ 0.5(小数视力表)。 自愿签署知情同意书。

Inclusion criteria

Aged 18 years or older. Clinically diagnosed with critical stage of corneal endothelial decompensation, accompanied by persistent corneal edema. For the study eye, central corneal thickness (CCT) is >= 620 μm or thicker than the contralateral healthy eye by > 50 μm. Best corrected visual acuity (BCVA) of the study eye ranges from hand motion to 0.5 (decimal visual acuity chart). Voluntarily sign the informed consent form.

排除标准:

研究眼存在活动性眼表或眼内感染/炎症。 合并严重青光眼、活动性眼底病变。 研究眼为无晶体眼或存在悬韧带松弛等不稳定因素。 对NAM或制剂中任何成分过敏。 妊娠或哺乳期妇女。 任何无法控制的全身性疾病。 无法按时随访者。

Exclusion criteria:

Presence of active ocular surface or intraocular infection/inflammation in the study eye. Complicated with severe glaucoma or active fundus lesions. The study eye is aphakic or has unstable factors such as lax zonular ligaments. Allergy to NAM or any components in the preparation. Pregnant or lactating women. Any uncontrolled systemic diseases. Those unable to attend follow-up visits on time.
