It can affect children, young people and adults and isbecoming more common. Ocular complications associated with DM are progressive and rapidly becoming the world's most significant cause of morbidity and are preventable with early detection and timely treatment. This review provides an overview of five main ocular complications associated with DM, diabetic retinopathy and papillopathy, cataract, glaucoma, and ocular surface diseases.展开更多

This study aimed at evaluating the efficacy and safety of adjunctive intravitreal bevacizumab （IVB） injection in conjunction with Ahmed glaucoma valve implantation （AGVI） in the management of NVG. Methods This was a retrospective study of patients with NVG in whom AGVI was performed between October 2008 and May 2012. The sample was divided into two groups according to the pretreatment： with adjunctive IVB injection （the IVB group, n=25 eyes） and without adjunctive IVB injection （the control group, n=28 eyes）. The surgical success rate, number of antiglaucoma medications used, best-corrected visual acuity （BCVA）, postoperative complications, regression, and recurrence of iris neovascularization （NVI） were analyzed between the groups. Results The surgical outcomes of the two groups were compared. The complete success rates in the IVB and control groups were 84.0% and 64.3% at 12 months and 80.0% and 53.6% at 18 months, respectively. There was a significant difference between the two groups （P=0.041）. Mean postoperative intraocular pressures, mean number of postoperative antiglaucoma medications, and BCVA were not significant between the two groups. The NVI in 22 （88.0%） eyes had completely regressed within 2-8 days after IVB. However, NVI recurred in 10 eyes （40.0%） 2-9 months later after IVB. The IVB group had only 1 case （4.0%） of hyphema out of 25 eyes, while there were 8 （28.6%） cases of hyphema out of 28 eyes in the control group （P=0.026）.Conclusions This study showed that preoperative IVB injection reduced NVI remarkably, decreased hyphema, and led to higher surgical success rates. Pre-operative IVB injection may be an effective adjunct to AGVI in the management of NVG.展开更多

The aim of this study was to evaluate the clinical outcomes of Ahmed glaucoma valve implantation （AGVI） in neovascular glaucoma （NVG） and non- NVG patients. Methods This prospective, non-randomized study included 55 eyes of 55 patients with refractory glaucoma; 27 had NVG （NVG group） and 28 had non-NVG （non-NVG group）. All of the patients underwent AGVI. The NVG group was adjunctively injected with intravitreal ranibizumab/bevacizumab （IVR/IVB） before AGVI. Intraocular pressure （lOP） was the primary outcome measure in this study. Surgical success rate, number of antiglaucoma medications used, best corrected visual acuity （BCVA）, and postoperative complications were analyzed between the groups. Results All of the patients completed the study （follow-up of 12 months）. Kaplan-Meier survival curve analysis indicated that the qualified success rates in the NVG and non-NVG groups at 12 months were 70.5% and 92.9%, respectively; this difference was significant （P=-0.036）. The complete success rates in the NVG and non-NVG groups at 12 months were 66.7% and 89.3%, respectively （P=0.049）. Compared with preoperative examinations, the postoperative mean lOP and use of medications were significantly lower at all follow-up time points in both groups （all P 〈0.05）. There were significant differences in BCVA between the two groups at the 12-month follow-up （X2=9.86, P=0.020）. Cox proportional hazards regression showed NVG as a risk factor for surgical failure （RR=15.08, P=0.033）. Postoperative complications were similar between the two groups. Conclusions AGVI is a safe and effective procedure in refractory glaucoma, but the success rate of surgery was related to the type of refractory glaucoma. The complete and qualified success rates of NVG patient adjunctive anti-vascular endothelial growth factor treatment are still lower than those of non-NVG patients.展开更多

It is referred to as an ＂end-stage＂ ocular disease. Conventional treatments for extremely uncontrolled NVG cases include retinal cryotherapy or enucleation. Major advancements in the diagnosis and the treatment of NVG, such as glaucoma drainage implant surgery and anti-vascular endothelial growth factor （anti-VEGF） treatment, have led to a new era in the management of this condition. However, many challenges still remain to be overcome.展开更多

The causes of neovascular glaucoma included：diabetic retinopathy（25 eyes）,and retinal vein occlusion（20 eyes）.All patients received preoperative IVR combined with postoperative PRP. The mean best-corrected visual acuities（BCVA）were converted to the logarithms of the minimum angle of resolution（log MAR）for the statisitical analyses.Intraocular pressure（IOP）,the log MAR BCVA and surgical complications were evaluated before and after surgery.The follow-up period was 12 mo.RESULTS：A total of 39 cases showed complete regression of iris neovascularization at 7d after injection,and 6 cases showed a small amount of residual iris neovascularization. The success rates were 81.8% and 82.6% at 12 mo after trabeculectomy and AGV implantation,respectively. In the trabeculectomy group,the log MAR BCVA improved at the last follow-up in 14 eyes,remained stable in 6 eyes and decreased in 2 eyes. In 4 cases,slight hyphemas developed after trabeculectomy. A shallow anterior chamber developed in 2 cases and 2 vitreous hemorrhages. In the AGV group,the log MAR BCVA improved in 14 eyes,remained stable in 5 eyes and decreased in 4 eyes. Slight hyphemas developed in 3 cases,and a shallow anterior chamber in 3 cases. The mean postoperative IOP was significantly lower in both groups after surgery（F=545.468,P〈0.05）,and the mean postoperative log MAR BCVA was also significantly improved（F=10.964,P〈0.05）with no significant difference between two groups.CONCLUSION：It is safe and effective to treat NVG with this combined procedure,and we found similar results after IVR＋A展开更多

Findings such as intraocular pressure(IOP) number of anti-glaucoma medications, visual acuity(VA), surgical success rates,and complications were recorded.RESULTS:AfterAGVimplantation,IOPwas18.2±4.0mmHg,15.5±3.3 mm Hg and 9.8±2.6 mm Hg at 6, 12 and 36 mo,significantly decreased compared with pre-IOP(P 【0.01).The number of anti-glaucoma medications was 0.9 ±0.5,0.8 ±0.9 and 0.8 ±0.6 at 6, 12 and 36 mo, significantly decreased compared to pre-treatment(P 【0.01). At last visit, there were 19 eyes with stable VA, 4 with VA improvement, 12 with diminished VA and 3 with complete loss light perception. There were 7 cases that failed during 3-year fellow up period. Cumulative probabilities of valve survival by Kaplan-Meier analysis were 82.9%,74.1% and 71.0% at 12, 24 and 36 mo, respectively. Cox stepwise regression analysis found that the survival time was significant associated with the pre-visual acuity 【2/400(P 【0.05). Post-operative complications occurred in 8eyes, of which hyphema presented in 2 eyes, choroidal effusion in 2 eyes.CONCLUSION:The procedure of preoperative IVB andAGV implantation should be one of treatments for NVG because of its safety and effectiveness.展开更多
