Abstract:
Objective To study the clinical effect of laser therapy for patients with diabetic retinopathy of different stages,and to observe the prognosis,thus to provide basis for clinical diagnosis and treatment.Methods 103 patients(197 eyes) with diabetic retinopathy were selected,they were divided into group A(69 eyes with proliferative diabetic retinopathy) and group B(45 eyes of non proliferative diabetic retinopathy) and group C(83 eyes with severe non proliferative diabetic retinopathy).All patients were treated with laser therapy,compared the improvement of visual acuity and retinal lesion of 12-18 months in each group and the final number of surgical cases needed.Results Visual acuity improvement:the total effective rate of group A was 69.6％ (48/69),which of group B was 91.1％ (41/45),which of group C was 78.3％ (65/83),the differences were statistically significant (x2 =14.216,12.132,8.316,all P ＜ 0.05).Improvement of retinopathy:the total effective rate of group A was 76.8％ (53/69),that of group B was 95.5％ (43/45),which of group C was 85.5％ (71/83),the differences were statistically significant (x2 =12.031,8.042,8.129,all P ＜0.05).9 cases needed surgical treatment in group A,accounting for 13.0％,1 case needed surgical treatment in group B,accounting for 2.2％,3 cases needed surgical treatment in group C,accounting for 3.6％,which of group A was significantly higher than group B (x2 =8.021,P ＜0.05) and group C (x2 =7.103,P ＜ 0.05),there was no statistically significant difference between group B and group C (x2 =0.632,P ＞ 0.05).Conclusion Laser treatment of different stages of diabetic retinopathy patients has different effects,choosing the right time to use laser therapy has great significance for improving the visual acuity and fundus diseases of the patients.
