Different wavelength krypton lasers in treatment of diabetic retinopathy / 中华眼底病杂志

ABSTRACT

Objective To investigate the therapeutic effect of different wavelength krypton lasers on diabetic retinopathy. Methods A total of 55 eyes (35 cases) with diabetic retinopathy underwent different wavelength krypton lasers photocoagulation treatment, according to the different manifestation of the affected eyes. The visual acuity, intraocular pressure,visual field,visual evoked potential were examined, and slit lamp, ophthalmoscopy, B ultrasonography, and fundus fluorescein angiography were performed preoperatively. The patients were followed up for at least 12 months after krypton laser treatment. Results The resulting effect on visual acuity after 12 months of photocoagulation in this series revealed that, 20 eyes (36.4%) improved, 34 eyes (61.8%) remained no change, and one eye (1.8%) decreased. Conclusions Different wavelength krypton lasers photocoagulation can be used in treatment of diabetic retinopathy and can improve the visual acuity at certain extent.
