Filter by:This retrospective data review study will evaluate anti-VEGF injections for retinal vein occlusion (RVO) or diabetic macular edema (DME).
This study will evaluate the safety and efficacy of OZURDEX® (700 µg dexamethasone implant) in patients with macular edema associated with branch retinal vein occlusion.
The purpose of the study is to determine the effect of Intravitreal Aflibercept Injection (IAI) on previously treated Central Retinal Vein Occlusions (CRVOs) with other Anti-VEGF agents.
Retinal vein occlusion (RVO) is a common vascular disease of the eye. Studies have shown that the risk of venous thrombosis is higher in winter so even concerning RVO. Studies have shown a possible link between sun exposure and venous thrombosis. Vitamin D levels have been shown to have a similar seasonal variation, with a peak occurring in the summer. The primary source of vitamin D is from sunlight when ultraviolet B (UVB) radiation penetrates the skin and converts 7-dehydrocholesterol to 25-hydroxycholecalciferol vitamin D3 (25-OHVitD) via previtamin D. In Stockholm situated at latitude 59˚ 20΄ North, it is not possible to synthesize vitamin D at sufficient levels in winter and the exposure time required to reach a standard dose is impractical from at least October through March. The aim of the study is to evaluate vitamin D levels in central retinal vein occlusion (CRVO) patients and compare them with the vitamin D levels in randomly selected control patients matched for age and month of disease onset. This is to evaluate whether vitamin D deficiency may be a risk factor in the onset of CRVO. The hypothesis of the study is that patients with CRVO have lower levels of vitamin d than matched controls.
To measure the pro-permeability factors in the aqueous humor of patients with persistent/recurrent macular edema after an injection of Ozurdex.
to evaluate the wall-to-lumen ratio (WLR) of retinal arterioles in hypertensive patients with retinal vein occlusion (RVO) before and after dexamethasone intravitreal implant 0.7 mg (DEX) compared to a matched control group of normal eyes in non-hypertensive subjects.
To evaluate the efficacy and safety of a dexamethasone-implant alone or in combination with bevacizumab. 64 eyes are prospectively investigated. Group 1 (22 CRVO and 16 BRVO) is treated with dexamethasone-implant alone, Group 2 (14 CRVO 12 BRVO) with three consecutive bevacizumab injections followed by a dexamethasone-implant. Recurrences are treated with dexamethasone-implant only. Patients are seen preoperatively and thereafter in monthly intervals. The primary endpoint was BCVA at twelve months.
The purpose of this study is to look at how effective, safe, and well tolerated Intravitreal Aflibercept Injection is in subjects with Central Retinal Vein Occlusion (CRVO) or Proliferative Diabetic Retinopathy (PDR).
To see if Lucentis 0.5mg combined with Targeted Pan Retinal photocoagulation will decrease the total number of intravitreal injections in a year for ischemic central retinal vein occlusion, hemi-retinal vein occlusions and branch retinal vein occlusions compared to standard of care
To conduct a precision study to assess the microperimetry function of the Spectral OCT/SLO. The study will assess variability across measurements taken by three different operator-device configuration across clinical sites, variability between subjects within a given operator-device configuration, and variability within a subject for a single operator-device configuration.
