Objective To learn the prevalence and risk factors of diabetic retinopathy (DR) of provincial civil servants (more than 40 years old) in Guangdong, China. Methods Total of 3844 Guangdong provincial civil servants over 40 years old were enrolled in this study. All participants diagnosed with diabetes underwent a complete ophthalmologic examination, including stereoscopic fundus photography and optical coherence tomography. Photographs were graded in a masked manner to assess the presence and severity of DR and diabetic macular edema (DME). Results Of 3844 civil servants, DM was confirmed in 155 patients, the prevalence was 4.03%. Of 155 DM patients, DR was in 11 patients, the DR prevalence was 7.10%. There were statistically differences on the fasting blood glucose (FBG), total cholesterol, low density lipoprotein and whether or not to use insulin between DR group and non DR group (t=3.158, 2.200, 2.050;chi;2=5.128; P＜0.05). High-FBG values, high blood lipids, INS applications had accelerated the occurrence and development of DR. The high FBG and the insulin using were the independent risk factors of DR. Conclusions DR prevalence is 7.10% in Guangdong provincial civil servants more than 40 years old. The high FBG and the insulin using are the independent risk factors of DR.
ObjectiveTo investigate the risk factors for neovascular glaucoma (NVG) after vitrectomy in proliferative diabetic retinopathy (PDR) patients. MethodsThree hundred and one patients (301 eyes) with PDR who underwent vitrectomy between January 2008 and December 2013 in our hospital were retrospectively evaluated. Risk factors for NVG after vitrectomy were identified by multivariate Logistic regression analysis. ResultsTwelve of 301 patients (4.0%) developed postoperative NVG in 2 to 18 months after vitrectomy. The incidence of postoperative NVG peaked in 2 to 6 months after vitrectomy (7 eyes, 58.3%). Logistic regression analysis showed that postoperative retinal detachment was a significant risk factor for postoperative NVG in eyes with PDR (P < 0.001). Eyes with postoperative retinal detachment were more likely to develop NVG after vitrectomy than those without postoperative retinal detachment (OR=17.826). Gender, age, duration of diabetes, preoperative serum creatinine levels, glycated hemoglobin levels, preoperative intraocular pressure, preoperative lens status, combined phacoemulsification surgery and tamponade were not associated with postoperative NVG (P > 0.05). ConclusionPostoperative retinal detachment is a major risk factor for NVG after vitrectomy in PDR.
