研究目的:

了解玻璃体腔内注射抗VEGF药物联合地塞米松植入剂(Ozurdex)治疗DME患者前后黄斑区结构、最佳矫正视力及前房水内相关的细胞因子的变化情况,评价玻璃体腔内注射抗VEGF药物联合地塞米松植入剂(Ozurdex)治疗DME的效果,为指导临床治疗提供新思路,以期为临床后续用药治疗提供相关参考依据。  

Objectives of Study:

To understand the changes in macular structure, best corrected visual acuity, and relevant cytokines in the anterior aqueous humor of patients with DME before and after intravitreal injection of anti VEGF drugs combined with dexamethasone implants (Ozurdex), evaluate the effectiveness of intravitreal injection of anti VEGF drugs combined with dexamethasone implants (Ozurdex) in the treatment of DME, and provide new ideas for guiding clinical treatment, with the aim of providing relevant reference basis for subsequent drug treatment in clinical practice.

药物成份或治疗方案详述:

观察组患者均按照3+1+1(即3次抗VEGF+1次Ozurdex+1次抗VEGF)治疗方案。所有患者均注射3次抗VEGF药物,两次注射时间间隔至少4周,治疗前记录BCVA、DRSS评分、黄斑中心凹厚度(central macular thickness,CMT)、黄斑区深浅毛血管网密度,并于第一次注射时行前房穿刺抽取0.05ml前房水送检,进行IL-6、IL-8、IL-10、VEGF、VCAM的定量分析(负责检查的单位为北京智德和医学检验所),送检及结果回报过程有专人负责。第三次注药后1个月时行玻璃体腔内Ozurdex注药,并于Ozurdex注药后第3个月再次行玻璃体腔抗VEGF注药,注射时再次行前房穿刺抽取0.05ml前房水送检,进行IL-6、IL-8、IL-10、VEGF、VCAM的定量分析与第一次注药时前房水中的细胞因子做比较。每次注药前3d抗生素滴眼液点眼,每天4次。按照内眼手术要求常规消毒铺巾,贴无菌黏贴,开睑器开睑,5%聚维酮碘溶液冲洗结膜囊,并眼表停留90秒后生理盐水彻底冲洗结膜囊。于10-11点位角膜缘后3.5 mm处垂直于巩膜进针,向玻璃体腔内注射康柏西普0.5 mg(0.05 mL)。棉棒轻压针口直至无出血及返流,手术结束时给予妥布霉素地塞米松眼膏点眼并包术眼。治疗后次日左氧氟沙星滴眼液,每日4次,连续3日。注射Ozurdex时的进针部位为颞下或鼻下方,药品用量为0.7mg。对照组患者均按照3+1+1(即3次抗VEGF+1次抗VEGF+1次抗VEGF)治疗方案进行,过程同观察组。 

Description for medicine or protocol of treatment in detail:

All patients in the observation group were treated with a 3+1+1 (i.e. 3 doses of anti VEGF+1 dose of Ozurdex+1 dose of anti VEGF) regimen. All patients were injected with anti VEGF drugs three times, with a minimum interval of four weeks between the two injections. BCVA, DRSS scores, central macular thickness (CMT), and density of the deep and superficial capillary network in the macular area were recorded before treatment. 0.05ml of anterior aqueous humor was extracted by anterior chamber puncture at the first injection for quantitative analysis of IL-6, IL-8, IL-10, VEGF, and VCAM (the unit responsible for the examination is Beijing Zhide Medical Laboratory), and a dedicated person is responsible for the examination and result reporting process. One month after the third injection, intravitreal Ozurdex injection was performed, and intravitreal anti VEGF injection was performed again three months after Ozurdex injection. During injection, 0.05ml of anterior chamber fluid was extracted by anterior chamber puncture again for examination. Quantitative analysis of IL-6, IL-8, IL-10, VEGF, and VCAM was performed and compared with the cytokines in the anterior chamber fluid during the first injection. Apply antibiotic eye drops to the eyes 3 days before each injection, 4 times a day. According to the requirements of internal eye surgery, perform routine disinfection and drape, apply sterile adhesive, use a eyelid opener to open the eyelid, rinse the conjunctival sac with 5% povidone iodine solution, and leave the surface of the eye for 90 seconds before thoroughly rinsing the conjunctival sac with physiological saline. Inject 0.5 mg (0.05 mL) of Conbercept into the vitreous cavity through a needle perpendicular to the sclera at a distance of 3.5 mm behind the corneal edge from 10 to 11 o'clock. Gently press the needle with a cotton swab until there is no bleeding or reflux. At the end of the surgery, apply tobramycin and dexamethasone eye ointment to the eye and wrap the surgical eye. The next day after treatment, levofloxacin eye drops were administered four times a day for three consecutive days. The injection site for Ozurdex is below the temporal or nasal area, and the dosage of the drug is 0.7mg. The control group patients were treated with a 3+1+1 (i.e. 3 times anti VEGF+1 time anti VEGF+1 time anti VEGF) treatment regimen, and the process was the same as that of the observation group.
