摘要
目的:对比C形格栅和环形格栅光凝治疗糖尿病性黄斑水肿的疗效。方法:选取弥漫性糖尿病性黄斑水肿患者60例97眼,随机接受C形格栅和环形格栅光凝治疗,其中C形格栅光凝60眼,环形格栅光凝37眼。观察激光前后视力变化,通过眼底荧光血管造影检查评估患者黄斑水肿的变化情况。结果:C形格栅光凝组水肿消退14眼(23%),水肿减轻38眼(63%),水肿无明显变化8眼(13%)。环形格栅光凝组共37眼,水肿消退7眼(19%),水肿减轻26眼(70%),水肿无明显变化4眼(11%)。两组疗效比较无明显统计学差异(P=0.852);C形格栅光凝组视力提高者13眼(22%),不变者41眼(68%),下降者6眼(10%)。环形格栅光凝组视力提高者6眼(16%),不变者27眼(73%),视力下降者4眼(11%)。两组疗效比较无明显统计学差异(P=0.570)。结论:C形光凝和环形光凝在减轻糖尿病性黄斑水肿和改善视力方面无明显差别,对于绝大多数糖尿病性黄斑水肿可行C形格栅光凝,对乳斑束存在明显局限水肿的患者可行环形光凝。
AIM ：To retrospectively analyze the therapeutic effects of ＂C＂ and ring grid photocoagulation in the treatment of diabetic macular edema（DME）. METHODS： A total of 97 eyes with diffuse diabetic macular edema were involved in the present study. All eyes were treated with grid photocoagulation： 60 eyes received ＂C＂ grid photocoagulation and 37 eyes received ring grid photocoagulation. The visual acuity and the macular edema were followed up for 6 months. RESULTS： After treatment with ＂C＂ grid photocoagulation, diabetic macular edema completely disappeared in 14 eyes （23%）, partly disappeared in 38 eyes （63%_, and remained unchanged in 8 eyes （13%~. After treatment with ring grid photocoagulation, diabetic macular edema completely disappeared in 7 eyes （ 19%）, partly disappeared in 26 eyes （70%）, and remained unchanged in 4 eyes （11% ）, which was not significantly different from ＂C＂ grid photocoagulation （P = 0. 852）. After treatment with ＂C＂ grid photocoagulation, visual acuity （VA） was improved in 13 eyes （22%）, maintained unchanged in 41 eyes （68%）, and decreased in 6 eyes （10%）. After treatment with ring grid photocoagulation, VA was improved in 6 eyes （16%）, maintained unchanged in 27 eyes （73%）, and decreased in 4 eyes （11%）, which was not significantly different from ＂ C＂ grid photocoagulation （P=0,570）. CONCLUSION. There is not significant difference between ＂ C＂ and ring grid photocoagulation in the treatment of DME. ＂ C ＂ grid photocoagulation is appropriate for most DME. But ring grid photocoagulation is necessary if there is edema in macular-disc fiber.
