Objective To investigate the risk factors associated with neovascular glaucoma (NVG) after pars plana vitrectomy (PPV) in eyes with proliferative diabetic retinopathy (PDR). Methods Retrospective study. One hundred and thirty-seven patients (137 eyes) with PDR who underwent PPV were recruited. There were 85 males and 52 females. The average age was (60.1±8.8) years old. The duration of diabetes was (10.2±3.6) years. There were 49 patients with ipsilateral carotid artery stenosis. Fifty-three eyes underwent intravitreal ranibizumab or conbercept injection before PPV. All eyes were treated with 23G standard three-port PPV. The average follow-up time after PPV was 11.5 months. Fundus fluorescein angiography (FFA) was conducted in postoperative 4-6 weeks to observe non-perfused retinal areas. Risk factors, such as ipsilateral carotid artery stenosis, the presence of non-perfusion in retina after PPV and the application of anti-vascular endothelial growth factor (VEGF) drugs before PPV, were identified by logistic regression. Results Twenty of 137 patients (14.6%) developed postoperative NVG after PPV. Ipsilateral carotid artery stenosis [odds ratio (OR) =5.048, 95% confidence interval (CI) 2.057-12.389,P=0.000] and the presence of non-perfusion in retina after PPV (OR=4.274, 95%CI 1.426-12.809,P=0.009) were significant risk factors for postoperative NVG, while the application of anti-VEGF drugs was not (OR=1.426, 95%CI 0.463-4.395,P=0.536). But the time from PPV to the onset of NVG varies significantly between the two groups of injection of anti-VEGF drugs or not (t=−4.370,P=0.000). Conclusions Risk factors associated with NVG after PPV in eyes with PDR included ipsilateral carotid artery stenosis and the presence of non-perfusion in retina after PPV. The application of anti-VEGF drugs before PPV can delay the onset of NVG in PDR eyes after vitrectomy.
ObjectiveTo investigate the awareness of diabetic retinopathy (DR) prevention and treatment knowledge of diabetic patients in the community of Shenzhen, and analyze its influencing factors.MethodsA cluster random sampling method was used to select 904 patients with diabetes diagnosed in 6 community health service centers in 2 administrative districts of Shenzhen and included in this study. Questionnaire survey of patients were performed to understand their knowledge of DR prevention and treatment. The multi-factor logistic regression analysis method was used to analyze the related influencing factors of DR prevention knowledge awareness.ResultsAmong 904 patients, 144 patients (15.93%, 144/904) knew about DR prevention and treatment knowledge. The highest awareness rate were about "Diabetes can affect vision and even cause blindness" (88.60%, 801/904). The lowest awareness rate (6.20%, 56/904) were about "DR treatment methods". About "diabetes requires regular fundus examinations" and "diabetics", the awareness rate of fundus examination interval were less than 50.00%. The results of multivariate logistic regression analysis showed that gender [odds ratio (OR)=1.595], education level (OR=2.963, 3.937), monthly income level (OR=3.871, 4.675), diabetes course ≥15 years (OR=1.829), treatment measures (OR=3.318, 4.512). Whether people had DR (OR=1.605) were important factors that affected the awareness of DR prevention and treatment knowledge (P＜0.05).ConclusionsThe overall awareness of DR prevention and treatment knowledge among diabetic patients in the community of Shenzhen is relatively low. Males, low education and income levels are the main influencing factors.

ObjectiveTo analyze the consistency of diagnostic results using simple and comprehensive reading methods on stereoscopic color fundus photographs of diabetic retinopathy (DR) with diabetic macular edema (DME). Methods450 sets of 7-field stereoscopic color fundus photographs of DR DME were compared to standard fundus photographs of early treatment and DR study group. The pictures were read by two groups of reader with similar experience. Two strategies were used to make the judgments, including simple reading which based on the color fundus photographs only, and comprehensive reading which based on color fundus photographs, fundus fluorescein angiography (FFA) and optical coherence tomography (OCT). 15 parameters were scored, including micro-aneurysms (MA), intra-retinal hemorrhage (IRH), hard exudates (HE), cotton wood spot (CW), intra-retinal microvascular abnormalities (IRMA), neovascularization on optic disc (NVD), neovascularization elsewhere (NVE), optic fiber proliferation (FPD), fiber proliferation elsewhere (FPE), pre-retinal hemorrhage (PRH), vitreous hemorrhage (VH), retinal elevation (RE), retinal detachment of central macular (RDC), venous beading (VB), Venous leak (VL). The reliability was evaluated using weighted κ(κw) statistic values. According to Fleiss statistical theory, κw≥0.75, consistency is excellent; 0.60≤κw < 0.75, consistency is good; 0.40≤κw < 0.60, consistency is general; κw < 0.40, consistency is poor. ResultsThe κw values of these 15 parameters were 0.22-1.00, 0.28-1.00 for the simple reading and comprehensive reading respectively. For simple reading, the consistency was poor for 8 parameters (MA, NVD, NVE, FPE, PRH, IRMA, VB, VL), general for 3 parameters (CW, FPD, VH), good for 2 parameters (IRH, HE) and excellent for 2 parameters (RE, RDC). For comprehensive reading, the consistency was poor for 2 parameters (NVE, VB), general for 6 parameters (MA, IRH, CW, FPE, IRMA, VL), good for 2 parameters (NVD, HE), excellent for 5 parameters (FPE, PRH, VH, RE, RDC). ConclusionThe comprehensive reading has higher consistency to judge the abnormality parameters of the fundus photographs of DR with DME.
ObjectiveTo investigate the related factors of the retina1 hemorrhage in newborns. Methods9558 newborns included in this observation between March of 2012 and July of 2013 in our hospital. The fundus was examined by the fully-integrated wide-field digital imaging system RetCamⅢat 0-4 days after born. According to the literature, retinal hemorrhage was classified into degreeⅠ, ⅡandⅢ. The condition for baby and the mother during pregnancy were correlatively analyzed. The other factors were analyzed including twins, premature delivery, big baby, mode of delivery, fetal birth, forceps delivery, suction delivery, asphyxia, jaundice, ABO hemolytic, cranial hematoma, intracranial hemorrhage, maternal age, first-time mom, the maternal previous mode of production, emergency delivery, the first stage of labor prolonged, the second stage of labor prolonged, the third stage of labor prolonged, pregnancy-induced hypertension, gestational diabetes, oxytocin, prenatal body mass index (BMI). Multivariate logistic regression analysis was used. ResultsIn 9558 cases of newborns, retinal hemorrhages were found in 2753 infants (28.8%), including 1137 degreeⅠ(41.3%), 895 degreeⅡ(32.5%) and 721 degreeⅢ(26.2%). Multivariate logistic regression analysis showed that the mode of delivery, asphyxia, jaundice, advanced maternal age, maternal previous birth, prenatal BMI is a risk factor for neonatal values retinal hemorrhage (r=0.146, 5.841, 1.847, 0.071, 0.246, 0.965;P < 0.05). The degree of fundus hemorrhage was not related to birth weight and BMI (P > 0.05). ConclusionsThe neonatal retinal hemorrhage rate was 28.8%. Mode of delivery, asphyxia, neonatal jaundice, maternal age, the previous mode of delivery of mothers with more than one previous birth, prenatal BMI values may be risk factors lead to retinal hemorrhage.
ObjectiveTo analyze the status and influencing factors of awareness of diabetic retinopathy (DR) knowledge in diabetics in Funing County, Jiangsu Province. MethodsThis is a cross-sectional study. In 2021, a total of 2 125 residents with diabetes in Funing County, Jiangsu Province were recruited using cluster random sampling methods. General examinations were performed and ophthalmological evaluation were conducted including visual acuity in daily life, slit lamp microscope with preset lens, digital non-mydriatic fundus photography. Clinical assessment and classification of DR were according to the international standard clinical classifications of diabetic retinopathy in 2019. DR was classified into no obvious DR, mild non-proliferative diabetic retinopathy (NPDR), moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR). Field questionnaire surveys were conducted to show the awareness rate of DR knowledge. Then Chi-square test and Logistic regression analysis were used to investigate influencing factors. ResultsAmong 2 125 subjects, 762 (35.86%, 762/2 125) residents were male and 1 363 (64.14%, 1 363/2 125) residents were female. A total of 444 (20.89%, 444/2 125) subjects were diagnosed as DR. Among which, 438 (20.61%, 438/2 125) subjects were NPDR, 6 (0.28%, 6/2 125) subjects were PDR. A total of 419 (19.72%, 419/2 125) subjects were diagnosed as cataract. The topic awareness rates were all below 45.00%. The overall population awareness rate was 19.45% (4 959/25 500). Awareness rate was correlated with age, visual acuity in daily life, education level, family history of diabetes, diabetic retinopathy grades and the type of treatment for diabetes (P＜0.001). Logistic regression analysis showed that the knowledge rate of prevention and treatment of DR Decreased significantly in patients aged 60-79 compared with those aged under 50 (P＜0.05). Compared with those with visual acuity＜0.1 in daily life, the knowledge rate of DR prevention and treatment in those with visual acuity≥0.1 was significantly decreased (P＜0.05). While primary school to college education, with family history of diabetes, with DR, oral hypoglycemic agents and/or insulin treatment were associated with higher awareness rate (P＜0.05). ConclusionsThe DR knowledge level is low among diabetics in Funing County, Jiangsu Province in 2021. Age, visual acuity in daily life, education level, family history of diabetes, with DR and receiving drug treatments are main influencing factors for diabetic’s awareness.
Objective To investigate the clinical characteristics and death risk factors of patients with community acquired pneumonia and sepsis. Methods Data of 350 patients with community-acquired pneumonia and sepsis admitted to the Intensive Care Unit of Third Xiangya Hospital of Central South University from January 2015 to October 2021 were retrospectively analyzed, and their basic characteristics, laboratory results and treatment were analyzed. Results The absolute value of white blood cell, neutrophil ratio, absolute value of neutrophil, inflammatory index, liver and kidney function, coagulation function, cardiac enzymology, lactic acid and sequential organ failure evaluation score of patients with community acquired pneumonia sepsis in the non-survival group were higher than those in the survival group. Logistic regression analysis showed that respiratory rate, heart rate, mean arterial pressure, blood oxygen saturation, C-reactive protein, D-dimer, lactic acid, creatinine and lymphocyte ratio may be independent risk factors for 28-day death in patients with community-acquired pneumonia and sepsis.The receiver operating characteristic curve shows that the combination of the above indicators to predict the risk of death of patients has the best sensitivity, specificity and maximum area under the curve, which is superior to the prediction value of individual variables. Conclusions Patients in the non-survivor group of community-acquired pneumonia sepsis had more severe inflammatory response and organ function impairment. Respiratory rate, heart rate, mean arterial pressure, blood oxygen saturation, C-reactive protein, D-dimer, lactic acid, creatinine, lymphocyte ratio and other indicators are independent risk factors for death of patients with community-acquired pneumonia and sepsis, which have better prognostic value when combined.
