AIM: To observe the efficacy of fundus photocoagulation combined with triamcinolone acetonide(TA)in the treatment of diabetic retinopathy(DR). <p>METHODS: The clinical data of 94 patients(112 eyes)in our hospital from September 2016 to September 2017 were analyzed retrospectively. According to the treatment regimen, the patients were divided into fundus photocoagulation with TA group(study group, 54 cases 64 eyes)and fundus photocoagulation group(control group, 40 cases 48 eyes). The treatment conditions \〖best corrected visual acuity(BCVA), macular retinal thickness\〗 were monitored before treatment(T1)and after 7d, 1, 3 and 6mo of treatment(T2, T3, T4, T5), and the efficacy was assessed at T5, and the improvement times of clinical manifestations(fundus hemorrhage, exudation, retinal edema)were recorded, and the serological markers \〖intercellular adhesion molecule(ICAM-1)and vascular endothelial growth factor(VEGF)\〗 were measured at T1 and T5. <p>RESULTS: At T1 to T5, there were statistically significant differences in the between-group effects, time-point effects and interaction effects of between-group and time-point of BCVA and macular retinal thickness(<i>P</i><0.05). At T2 to T5, the BCVA was improved in the two groups with time while the macular retinal thickness was decreased with time(<i>P</i><0.05). The efficacy in study group was better than that in control group, and the improvement times of fundus hemorrhage, exudation and retinal edema were less than those in control group(<i>P</i><0.05). At T5, the serum levels of ICAM-1 and VEGF in the two groups were lower than those at T1, and the levels were lower in study group than those in control group(<i>P</i><0.05). <p>CONCLUSION: Fundus photocoagulation combined with TA can effectively improve the visual acuity and retinal edema in patients with DR, and it has significant efficacy, and it can help promote the recovery of clinical symptoms, reduce the vascular endothelial injury, and inhibit the neovascularization.
