Filter by:The purpose of this study is to determine whether ciliary body thickness increased in the presence of diabetic macular edema and whether it changed after pars plana vitrectomy.
This study evaluates a new investigational treatment regimen of three consecutive monthly doses of ranibizumab followed by an as-needed treatment regimen, with monthly follow-up for the first three months then two-monthly follow-up until 18 months in patients with visual impairment due to diabetic macular oedema.The aim of the study is to determine if this treatment regimen is effective and safe in these patients.
Treatment with Ranibizumab of the residual diabetic edema in patients with failed response to Bevacizumab.
The purpose of this clinical research study is to investigate the efficacy of predosing patients undergoing cataract surgery with the potent corticosteroid difluprednate ophthalmic emulsion 0.05% compared to prednisolone acetate 1% on corneal edema (swelling), and retinal thickness.
The purpose of this study is to compare visual improvement and total number of intraocular injections in eyes with macular edema following central retinal vein occlusion (CRVO)after initial treatment with Ozurdex (dexamethasone implant) or Avastin (bevacizumab).
The purpose of this study is to evaluate the safety end efficacy of combined phakoemulsification and vitrectomy with retinal endophotocoagulation and intraoperative use of bevacizumab in patients with diffuse diabetic macular edema (DDME), to determine the possible preoperative and intraoperative factors that might influence surgical outcomes.
To evaluate the effect of alpha lipoic acid (ALA) on the occurrence of diabetic macular edema.
Patients with chronic lower limb edema commonly suffered from extremities edema, pain, varicosities, venous stasis changes, and deep venous thrombosis. A common challenge for primary care physicians is to determine the cause and find an effective treatment for leg edema of unclear etiology. The aims of this project are to determine the cause of patients with chronic lower limb edema with conventional digital venography, the clinical value of role of 3D rotational venography or combined multidetector (MD)CT angiography and iliac venography using direct iliac venography for contrast administration via bilateral femoral catheterization (MDCT angiography/venography) with volume-rendering images supplementary to 2D digital venography in evaluation of patients with chronic lower limb edema. This project is designed as retrospective cross-sectional study. Between April 2008 and Dec 2009, a total of approximately 300 patients with chronic lower limb edema who had had bilateral iliac digital venography and surgery at our institution will be reviewed. All patients underwent surgery by one senior vascular surgeon for lower limb conditions within one month after the venographic examination. Patients who had incomplete clinical and surgical records or incomplete images will be excluded. The surgical findings of the presence, anatomical location, and size of the venous narrowing will assessed and described. Stenosis was defined as luminal narrowing of 50% or more compared to the prestenotic or poststenotic lumen.With use of surgical findings as a the standard, the investigators calculated and compared the diagnostic accuracies, sensitivities, specificities, positive predict values and negative predict values of 2D digital venography images alone, 3D rotational venography, and combined MDCT angiography/venography with volume-rendering images supplementary to 2D digital venography. With this large series study, the investigators believe that the cause of chronic lower leg edema in our patients' population will be clarified. The value of additional 3D rotational venography, and combination MDCT angiography/venography with volume-rendering images will lead to higher diagnostic performance and may provide a helpful tool for planning surgical and endovascular treatment, which has not been reported before.
This study is designed to report 3-year result of triple therapy of vitrectomy, intravitreal triamcinolone and macular laser photocoagulation for intractable diabetic macular edema. Previously author reported 1-year result(Am J Ophthalmol. 2007 Dec;144(6):878-885. Epub 2007 Oct 15.).
This study will asses sthe safety of pegaptanib sodium in patients with diabetic macular edema. The hypothesis is that pegaptanib is safe and efficacious in patients with diabetic macular edema.
