25-Gauge Vitrectomy With Ranibizumab or Triamcinolone Acetonide on Proliferative Diabetic Retinopathy in China

Proliferative diabetic retinopathy(PDR) is the leading cause of visual loss in diabetic patients. The operation indication includes non-absorbed vitreous haemorrhage, dense bleeding in front of the macular, proliferative vitreoretinopathy traction macular, tractional retinal detachment combined break, severe progressive fiber vascular proliferation and vitreous haemorrhage combined with early iris neovascularization. Due ...

Microalbuminuria as a Cardiovascular Risk Factor (PRECISED Substudy)

A hypothesis free approach by using proteomic/metabolomic analyses in the urine samples of selected populations seems an appropriate approach by which to explore this issue. In addition, a driven hypothesis in the same groups of patients based on a sensitive marker of kidney injury also seems appropriate. Urinary levels of ...

Imaging Parameters and DME Treatment Response

The investigators hypothesize that DME is a common endpoint caused by differing pathobiology which varies between patients. Clinically fluorescein angiography (FA) and optical coherence tomography (OCT) are used to diagnose and assess diabetic retinopathy including DME. These two imaging modalities provide different biological information with FA giving functional data regarding ...

Comparison of Retinal Oxygenation and Retinal Vessel Diameters in Healthy Subjects and Patients With Diabetic Retinopathy or Retinal Vein Occlusion Between DVA and Oxymap

To date two different instruments are commercially available to measure retinal oxygen saturation and retinal vessel diameters: Dynamic Vessel Analyzer (DVA) and Oxymap. Retinal oxygen saturation analysis is based on spectroscopic evaluation of retinal fundus images. Up to now no data comparing both instruments for the measurement of retinal oxygen ...

Early Laser Treatment for Diabetic Eye Disease in China : A Pilot Randomized Trial

China now has the world's largest number of diabetic persons. Population studies show that only 10% of Chinese rural-dwellers with DR receive therapy. The current standard approach to treatment of DR often requires patients to return for multiple examinations over years, before they reach trial-proven criteria for treatment. This long ...

Anti-VEGF vs. Prompt Vitrectomy for VH From PDR

Although vitreous hemorrhage (VH) from proliferative diabetic retinopathy (PDR) can cause acute and dramatic vision loss for patients with diabetes, there is no current, evidence-based clinical guidance as to what treatment method is most likely to provide the best visual outcomes once intervention is desired. Intravitreous anti-vascular endothelial growth factor ...

Analysis of Angiogenic Factor Levels in Eyes With Diabetic Retinopathy

This prospective, case-control study included 50 patients(50eyes) with severe nonproliferative diabetic retinopathy or proliferative diabetic retinopathy and 50 patient with nondiabetic retinopathy or cataract. Aqueous humor was taken before injection of anti-vascular endothelial growth factor agent or pars plana vitrectomy for other retinal disease. Angiogenic and non-angiogenic proteins were analyzed.

Phase N/A

Endolaserless Vitrectomy With Intravitreal IAI for PDR-Related VH

This is a phase I/II open label, randomized, interventional clinical trial. Study eyes will receive one preoperative intravitreal aflibercept injection (IAI) <21 days but >7 days prior to vitrectomy and one intraoperative intravitreal aflibercept at end of surgery followed by randomization in a 1:1 ratio into either 4 mandatory postoperative ...

Phase

International Consortium Investigating Early Vitrectomy in Diabetic Macular Edema Patients

The purpose of this research is to evaluate the effectiveness of vitrectomy for the treatment of diabetic macular edema. Diabetes is known to cause retinal blood vessels to leak, leading to swelling of the central retina (macula), and decreased vision. Removing the vitreous gel with vitrectomy surgery is known to ...

Phase N/A

Liver X Receptor (LXR) as a Novel Therapeutic Target in Diabetic Retinopathy (DR)

Diabetic retinopathy (DR) is a disabling microvascular complication. Despite recent advances using pharmacotherapy, a cure for DR has yet to be realized. Thus, a conceptual and technical breakthrough to identify novel targets, and a strategy to cure this complication is paramount. We believe that the recent clinical evidence from large ...
