Active clinical trials for "Retinal Vein Occlusion"

This is a retrospective data collection study to evaluate the efficacy, safety, and re-injection interval of OZURDEX® in the treatment of macular edema due to RVO. Following informed consent, there were no patient study visits. All data was collected via chart review.

To evaluate the long term outcomes of pars plana vitrectomy (PPV), with and without internal limiting membrane (ILM) peeling, in eyes with persistent macular edema secondary to branch retinal vein occlusion (BRVO). Results suggest the following hypothesis: PPV, with and without ILM peeling, appears to be beneficial in eyes with persistent macular edema due to BRVO Effectiveness is maintained long term ILM peeling does not significantly affect postoperative best corrected visual acuity (BCVA)

Blindness can be caused by many ocular diseases, such as diabetic retinopathy, retinal vein occlusion, age-related macular degeneration, pathologic myopia and glaucoma. Without timely diagnosis and adequate medical intervention, the visual impairment can become a great burden on individuals as well as the society. It is estimated that China has 110 million patients under the attack of diabetes, 180 million patients with hypertension, 120 million patients suffering from high myopia and 200 million people over 60 years old, which suggest a huge population at the risk of blindness. Despite of this crisis in public health, our society has no more than 3,000 ophthalmologists majoring in fundus oculi disease currently. As most of them assembling in metropolitan cities, health system in this field is frail in primary hospitals. Owing to this unreasonable distribution of medical resources, providing medical service to hundreds of millions of potential patients threatened with blindness is almost impossible. To solve this problem, this software (MCS) was developed as a computer-aided diagnosis to help junior ophthalmologists to detect 13 major retina diseases from color fundus photographs. This study has been designed to validate the safety and efficiency of this device.

Purpose: To evaluate retinal functional improvement by means of visual acuity and retinal sensibility examination after intravitreal dexamethasone implant in patients affected by cystoid macular edema secondary to retinal vein occlusion.

This is a prospective, non-interventional, multi center post-authorization safety study that includes patients with a diagnosis of CRVO. The investigator will have made the choice of treatment (EYLEA) as well as the decision to use EYLEA according the Japanese Package Insert prior to enrolling the patient in this study. The observation period for each patient starts when therapy with EYLEA is initiated. The enrollment period is 2 years. Patients will be followed for a time period of 2 years or until it is no longer possible (e.g. lost to follow-up) within the 2 years. For each patient, data are collected as defined in the case report form at the initial visit, follow-up visits and final visit, either by routine clinical visits (as per investigators routine practice). There will interim analysis of study data: 6 months after last patient first visit and J-PSUR(Japanese-Periodic Safety Update Report )

Ozurdex(TM) has recently been FDA approved for use in macular edema secondary to retinal vein occlusion. It remains unclear how quickly the drug works and for how long as the initial studies did not have frequent anatomic monitoring. This study will utilize frequent Spectral domain OCT imaging to better understand the onset of treatment effectiveness and duration of action on the anatomic thickness of the retina, in addition to distinguishing structural abnormalities of responders from non-responders.

This study is a multicenter, prospective, observational study to evaluate the long-term safety of OZURDEX® in patients with macular oedema following central retinal vein occlusion (CRVO) or branch retinal vein occlusion (BRVO) or patients with non-infectious posterior segment uveitis in real-world clinical practice.

This multicenter observational study will assess the efficacy and tolerability of OZURDEX® in clinical practice, and will assess the time at which patients are considered for retreatment.

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 saturation and vessel diameter are available in the literature. Study objectives: To compare retinal oxygenation and retinal vessel diameters in healthy subjects and patients with diabetic retinopathy or retinal vein occlusion between 2 commercially available systems (DVA, Oxymap T1) Study design: Open pilot study Study population: 30 healthy volunteers, age 18-80 years 30 type 2 diabetic patients with mild or moderate non-proliferative diabetic retinopathy, age 18-80 years 30 patients with retinal vein occlusion, age 18-80 years Topically administered medication: Tropicamide (Mydriaticum "Agepha"®, Agepha, Vienna, Austria), dose: 1-2 drops per study day for dilation of the pupil Oxybuprocainhydrochloride combined with sodium fluorescein (Thilorbin®, Alcon Pharma GmbH, Freiburg, Germany), dose: 1 drop in one eye for measurements of intraocular pressure Nonylacidvanillylamide combined with Nicotinic-acid--ß-butoxyethylester (Finalgon®, Boehringer Ingelheim RCV GmbH & Co KG, Vienna, Austria): topical on the earlobe Methods: Dynamic vessel analyzer Oxymap T1 Blood pressure and pulse rate measurement Applanation tonometry Oxygen and carbon dioxide partial pressure measurement in arterialized blood from earlobe Main outcome variables: Difference of oxygen saturation of retinal vessels between DVA and Oxymap T1 The motive for this investigation is to compare data between 2 commercially available instruments for the measurement of retinal oxygen saturation and retinal vessel diameter in healthy subjects as well as in patients with ocular disease associated with altered retinal oxygenation. Comparative data from both systems are currently not available. Data from this study will allow the comparison of studies performed with different systems. All oxygen measurement procedures are non-invasive and painless. Hence, the risk/benefit ratio appears to be acceptable.

The objective of this retrospective chart review is to evaluate drug utilization, usage patterns and indication of effectiveness Eylea in the routine clinical (real-life) management of patients who suffer from ME (Macular Edema), secondary to CRVO (Central Retinal Vein Occlusion), and who started treatment with Eylea for this indication.
