Filter by:The present study will provide additional efficacy and safety data for 0.5-mg ranibizumab using as needed (PRN) dosing over 24 months in patients with visual impairment due to macular edema secondary to Central Retinal Vein Occlusion (CRVO). Spectral domain high-definition optical coherence tomography (OCT) images will be analyzed to gain insights into predictive factors for disease progression and the possibility of reduced monitoring will be assessed in Year 2. The results of this open-label study will provide long-term safety and efficacy data to further guide recommendations on the use of ranibizumab in this indication.
This study examines two doses of Ranibizumab (0.5mg and 1.0mg) for the treatment of macular edema secondary to retinal vein occlusion in patients that have previously failed treatment with other macular edema treatments including bevacizumab.
The purpose of this study is to compare ranibizumab injection to hemodilution at the early phase of Central Retinal Vein Occlusion (CRVO) and to determine if the combination of both treatments may have a synergic effect.
This clinical trial is designed to compare ranibizumab in comparison with Dexamethasone implant® after 6 months of treatment. In the study arm Lucentis will be given monthly in a pro re nata scheme whereas the comparator Dexamethasone implant is given once at Month 0 with sham injections PRN afterwards.
Recent studies have shown a remarkably positive effect of 6 monthly injections of Ranibizumab on eyes with CRVO. The disease may cause severe sight threatening complications, partly due to restrictions in blood flow and oxygenation . Although Ranibizumab has been shown affective to reduce oedema of the retina, it is not known whether the drug ameliorates or aggravates restrictions in oxygenation. The Oxymap oximeter allows a non-invasive measurement of the oxygen saturation in retinal vessels and thus the state of retinal oxygenation. The primary objective of the study is to evaluate the effects of injections of Ranibizumab on the retinal oxygen saturation in eyes with newly diagnosed central retinal vein occlusion (CRVO), The secondary objective is to evaluate the effects of injections of Ranibizumab on visual acuity and retinal oedema in eyes with different degree of ischemia.
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).
To evaluate the effect of intravitreal bevacizumab with intravitreal triamcinolone for the treatment of central retinal vein occlusion (CRVO) presenting poor visual acuity.
The purpose of this study is to determine whether ranibizumab (Lucentis) will be effective in reducing if not eliminating the macular edema associated with the disease, central retinal vein occlusion (CRVO).
The purpose of this study is to determine whether a fluocinolone sustained drug delivery implant is effective in the treatment of central retinal vein occlusion that has caused persistent macular edema and decreased visual acuity.
Central retinal vein occlusion is a leading cause of severe visual impairment. Until now, no treatment has been available to improve visual acuity. The present study intends to investigate if intravitreal bevacizumab can improve visual acuity as compared to sham-treated control patients.
