Abstract
METHODS: We conducted a retrospective analysis of 70 diabetic retinopathy patients(70 eyes)who accepted vitreous surgery in our hospital due to vitreous hemorrhage or vitreous retina traction change from March 2011 to March 2013. In follow-up clinics, according to the difference of patient's retinal photo-coagulation range, we divided it into extra-panretinal photocoagulation group(40 patients)and panretinal photocoagulation(30 patients), respectively observed the best corrected visual acuity, intraocular pressure and retinal vessel changes in two groups and made statistical analysis.
RESULTS: Through comparing the eye condition, visual acuity after 3mo, intraocular pressure between the two groups patients, the difference had no statistical significance(all of the P>0.05). Comparing the incidence of retinal blood vessel leak, posterior pole exudate, and posterior pole bleeding points in two groups patients, the difference had statistically significant(all of the P<0.05). Comparing the incidence of no-perfusion area of retina, prepapillary vascular leak in two groups patients, the difference had statistically significant(P=0.04, 0.02). Comparing the incidence of macular edema in two groups patients after operation, the difference had no statistically significance(P=1.00). Comparing the extinction time of macular edema, the difference had statistically significant(P<0.05), extra-panretinal photocoagulation group was better than panretinal photocoagulation.
CONCLUSION: To cure proliferation diabetic retinopathy, adopting the extra-panretinal photocoagulation has a better curative effect than panretinal photocoagulation on curing no-perfusion area of retina, retinal blood vessel leak, prepapillary vascular leak in operation on vitreous. However, the excessive retinal photocoagulation has a clear damage on retina and choroid. Therefore, in the treatment, while covering the retinopathy as far as possible, it is important to master the laser energy and spot number preventing the complications.
