白内障术后糖尿病性视网膜病变多波长激光治疗

Objective To investigate the effect and opportunity of multiwavelength laser Photocoagulation on diabetic retinopathy after cataract extraction combined with intraocular lens implantation. Methods Retrospective analysis. Forty-seven eyes (35cases) with diabetic retinopathy after cataract extraction combined with intraocular lens implantation staged by examination results of retinophotoscopy, FFA and OCT two weeks later. All patients received multiwavelength laser Photocoagulation relied on diseased region and stage in third week, including local Photocoagulation, grid pattern Photocoagulation and panretinal Photocoagulation. Results All patients completed 3-12 months of follow-up. In all eyes, visual acuity improved in 11 eyes, remained stable in 32 eyes, decreased in 6 eyes, accounting for 23.40%, 63.83%, 12.77%, respectively. FFA showed that macular edema subsided completely in 23 eyes, subsided partly 16 eyes, remained stable or even worsen 8 eyes, accounting for 48.94%, 34.04%, 17.02%, respectively. OCT showed the mean forveal thickness were (390.3± 102.5)μ m before Photocoagulation and (287.67± 82.81)μ m, (208.47± 56.72)μ m, (168.38±42.560)μ m after Photocoagulation 1 month, 3 and 6 months, respectively, the difference was significant (P＜0.05). Retinal capillary leakage subsided extensively or neovascular atrophied completely 20 eyes, invalid 4 eyes by FFA. Conclusions To examine patients by retinophotoscopy, FFA and OCT in time after cataract extraction combined with inuaocular lens implantation and then receive multiwavelength laser Photocoagulation rely on diseased region and stage, such can control further development of diabetic retinopathy and conserve vision function effectively.
