目的评估递法明片对全视网膜光凝(PRP)术后视网膜功能损伤修复的促进作用。
方法采用非随机对照研究方法,于2014年12月至2020年2月在北京同仁眼科中心和北京市大兴区人民医院纳入非增生性糖尿病视网膜病变(NPDR)患者108例108眼。根据患者自愿原则将患者分为2个组,其中PRP+递法明组患者56例56眼,于PRP后口服递法明片;PRP组患者52例52眼,未服用递法明片。于PRP治疗前及治疗后1 d及1、3、6、12个月对患者进行随访,采用国际视力表检查患眼视力;采用Humphrey视野计检查30°~60°环形视野并采用RETLscan系统记录多焦视网膜电图;采用光相干断层扫描仪检测黄斑中心凹厚度(CMT);分别于PRP后6个月、12个月采用荧光素眼底血管造影观察眼底新生血管情况。
结果PRP+递法明组末次随访时视力治疗有效率为57.14%(32/56),明显高于PRP组的32.69%(17/52),差异有统计学意义( χ 2=3.56, P<0.05)。2个组治疗前后各时间点视野平均阈值敏感度总体比较差异均有统计学意义( F 分组=4.77, P<0.05; F 时间=6.51, P<0.05),2个组治疗后视野平均阈值敏感度均较治疗前降低,差异均有统计学意义(均 P<0.05);PRP+递法明组治疗后3、6、12个月视野平均阈值敏感度值均高于PRP组,差异均有统计学意义(均 P<0.05)。PRP+递法明组第3、4、5环的P1波振幅密度高于PRP组,差异均有统计学意义(均 P<0.05)。2个组治疗前后不同时间点CMT总体比较差异均无统计学意义( F 分组=3.57, P>0.05; F 时间=1.23, P>0.05)。治疗后12个月,所有患眼均未出现视网膜新生血管及无灌注区。
结论口服递法明片可促进NPDR患眼PRP术后视网膜功能的恢复。
ObjectiveTo investigate the promoting effect of Difrarel ® on retinal function following panretinal photocoagulation (PRP) in the eyes with diabetic retinopathy.
MethodsA non-randomized controlled study was performed.A total of 108 eyes of 108 patients with non-proliferative diabetic retinopathy (NPDR) were enrolled in Tongren Ophthalmology Center and Beijing Daxing District People's Hospital from December 2014 to February 2020.The patients were divided into PRP group and PRP+ Difrarel ® group according to different therapies under patients' selection.Difrarel ® was orally administered after PRP in 56 patients of PRP+ Difrarel ® group, and only PRP was given in 52 patients of PRP group.The visual acuity, 30°~60° circular visual field and multifocal electroretinogram were examined before and 1 day, 1 month, 3 months, 6 months, 12 months after PRP.The central macular thickness (CMT) was measured by optical coherence tomography, and fundus neovascularization was observed by fluorescein fundus angiography at 6 and 12 months after PRP.The study protocol was approved by an Ethics Committee of Beijing Daxing District People's Hospital (No.2021-F4).
ResultsVisual improvement rate was 57.14% (32/56) and 32.69% (17/52) in PRP+ Difrarel ® group and PRP group at the end of following-up, respectively, showing a significant difference between two groups ( χ 2=3.56, P<0.05). The visual field mean sensitivity was significantly different at different time points in two groups ( F group=4.77, P<0.05; F time=6.51, P<0.05), and was lower after PRP than those before treatment in both groups (both at P<0.05), and was significantly higher in PRP+ Difrarel ® group than PRP group at 3, 6, 12 months after PRP (all at P<0.05). The P1 amplitude density in 3 to 5 rings in PRP+ Difrarel ® group were higher than those in PRP group, and the differences were statistically significant (all at P<0.05). There was no significant difference in CMT between the two groups at different time points ( F group=3.57, P>0.05; F time=1.23, P>0.05). No new blood vessels and non-perfusion area were found in both groups.
ConclusionsOral Difrarel ® can improve retinal function after PRP in the eyes with NPDR.
