View clinical trials related to Retinal Vein Occlusion.
Filter by:The objective of this study is to image retinal vascular alterations in patients with retinal disease using the AngioVue OCT-A system and understand the information these images provide. The investigators will image study participants who have retinal diseases with the AngioVue unit (Optovue) and will collect relevant clinical data to understand the nature of the information contained in images obtained on AngioVue. This study being conducted under an abbreviated IDE. The investigators will analyze data using descriptive statistics. Risks related to light exposure will be managed by ensuring that the exposure to the AngioVue light source is well below maximum permissible limits for safe exposure.
This interventional study will evaluate the retinal vascular dynamics associated with Intravitreal Aflibercept Injection (IAI) therapy in eyes with diabetic macular edema (DME) or macular edema secondary to retinal vein occlusion (RVO). Ultra-widefield fluorescein angiography and optical coherence tomography (OCT) angiography will be performed at multiple timepoints to assess the changes in retinal vascular leakage, ischemia, and vascular abnormalities throughout the study duration and compare these alterations to baseline.
Background/aims: Aflibercept is an approved therapy for neovascular macular degeneration (AMD), diabetic macular edema (DME), retinal vein occlusion and other retinal conditions. Ziv-aflibercept is also approved by FDA and is extremely cost-effective relative to the expensive same molecule aflibercept. In vitro and in vivo studies did not detect toxicity to the retinal pigment epithelium cells using the approved cancer protein, ziv-aflibercept. Ziv-aflibercept had no loss of anti-VEGF activity when kept at 4°C in polycarbonate syringes over 4 weeks. Similar to bevacizumab, compounded ziv-aflibercept would yield a tremendous saving compared to aflibercept or ranibizumab. Phase I studies and case reports did not report any untoward toxic effects but attested to the clinical efficacy of the medication. Our purpose is to ascertain the long-term safety and efficacy in various retinal diseases of intravitreal ziv-aflibercept. Methods: Prospectively, consecutive patients with retinal disease that require aflibercept (AMD, DME, RVO, and others) will undergo instead the same molecule ziv-aflibercept intravitreal injection of 0.05 ml of fresh filtered ziv-aflibercept (1.25mg). Monitoring of best-corrected visual acuity, intraocular inflammation, cataract progression, and retinal structure by spectral domain OCT to be done initially, one month, 6 months, 1 year, and 2 years after injections. Anticipated Results: Analyze signs of retinal toxicity, intraocular inflammation, or change in lens status, together with best corrected visual acuity and central foveal thickness at 1 month, 6 months, 1 year and 2 year. Anticipated Conclusions: Off label use of ziv-aflibercept improves visual acuity without ocular toxicity and offers a cheaper alternative to the same molecule aflibercept (or lucentis), especially in the third world similar to bevacizumab.
Monthly intravitreal ranibizumab (IVR) during the first 6 month had great effect for macular edema with branch retinal vein occlusion (BVO) both in visual and anatomical outcome. It is expected that similar results could be obtained by less frequent IVR. The purpose of this study is to investigate if IVR by PRN is as effective as by monthly. In addition, the investigators are going to study the relationship between macular edema and the size and location of retinal non-perfusion area.
Hyperbaric chamber treatment assists in increasing the amount of oxygen in the plasma and in the tissues and has been proven to be beneficial in treating different ischemic wounds, and acute retinal artery occlusion (ARAO) but its effect hasn't been tested in CRVO patients yet.
The goal is to conduct a 5-year prospective, randomized controlled trial to test an innovative, community-based intervention using posterior and anterior fundus photography of the optic nerve and macula and intraocular eye pressure measurements to improve access and utilization of eye care to detect, treat, and manage high-risk patients with previously undiagnosed glaucoma and other eye diseases. Research shows that subject failure to attend follow-up eye care appointments diminishes any previous benefits of community screenings for glaucoma. Greater adherence to follow-up visits can reduce glaucomatous blindness.
Phase 2a open-label study to assess the efficacy and safety of subcutaneous 15mg AKB-9778 administered twice daily for 84 days in subjects with macular edema due to RVO.
A phase 2, multicenter, randomized, active-controlled, masked, parallel arm study designed to evaluate the safety and efficacy of a single suprachoroidal injection of CLS-TA, triamcinolone acetonide injectable suspension, given along with an intravitreal (IVT) injection of aflibercept compared to IVT aflibercept alone in subjects with retinal vein occlusion (RVO).
Comparing ranibizumab and aflibercept in a treat and extend algorithm evaluating the number of needed injections over a 18 month period in patients with newly diagnosed CRVO.
The retinal vein occlusion (RVO) is the second most common retinal disease after diabetic retinopathy, and is a common cause of unilateral visual loss. The risk factors that predispose to RVO are many and are generally the same as those found in vascular alterations involving other parts of the body, as in the case of stroke or coronary heart disease. Several authors have attempted to determine whether the pathogenesis of RVO can be of arterial type, considering the disease as consequent to atherosclerosis, rather than resulting from venous disease. Although less frequent than the other diseases RVO affects considerably on health care costs. Direct medical costs showed that in one year a patient with this disease has a higher than average cost for a patient with hypertension or glaucoma. Knowing the prevalence of the disease in Italy and identify modifiable risk factors, recognizing additional risk factors related to gender, genetic predisposition and especially the social-economic and cultural background in the pathogenesis of RVO, are the objectives that led to the planning of this study. In order to assess the prevalence of the disease and the current "clinical practice" we aim to create an online register between Italian specialist centers (ophthalmic emergency care and thrombosis centers) with immediate portability and usability of the data.
