ABSTRACT

Objective Diabetic macular edema( DME) is a common complication of diabetic patients.Laser photocoagula-tion therapy is effective in the treatment of DME despite of some patients with unsatisfactory curative effect or recurrence.This study was to explore efficacy and safety of aescin combined with laser photocoagulation in DME treatment. Methods A total of 102 pa-tients with diabetic macular edema in our hospital were randomly divided into control group(51 cases of 67 eyes) and combined treat-ment group (51 cases of 69 eyes).Aescin combined with laser photocoagulation were applied in observation group, and laser photoco-agulation was applied in control group.Observation was made on the changes of intraocular pressure, best corrected visual acuity( BV-CA), central macular thickness(CMT) and the leakage in macular area between the two groups before and after he treatment, along with detection on adverse reactions during the treatment. Results Com-pared with pre-treatment, there were no significant differences be- tween the two groups in intraocular pressure at 1, 2, 3, 6 months after therapy(P>0.05), and compared with control group in the same time point, the intraocular pressure showed no change significantly in combined treatment group(P>0.05).Compared with con-trol group after therapy, the average value of BVCA in observation group showed significantly decreased at 2, 3, 6 months(Z=2.130, 1.932, 2.283;P=0.037, 0.028, 0.005) while the average value of CMT showed significant increase( Z=1.979, 2.315, 3.08;P=0.045, 0.031, 0.000).Compared with control group at the same time point, the number of patients who suffered from the leakage in macular area significantly decreased in combined treatment group at 2, 3, 6 months(χ2 =4.213, 5.074, 6.625; P=0.040, 0.024, 0.010) .7 patients(13.7%) in combined treatment group suffered from stomach and nausea during the treatment, without any observation of serious adverse reaction. Conclusion Conclusion Aescin combined with laser photocoagulation is effective for the rehabilitation of patients and chconsolidate effect with high safety, which is of great clinical application.
