Filter by:Bevacizumab is an anti-VEGF agent used in approved for use in metastatic colorectal carcinoma (FDA Approved). This study analyzes the safety and efficacy of off-label Intravitreal Injection of bevacizumab (Avastin) for CNVM, Macular oedema due to diabetic retinopathy, vascular occlusion and other retinal disorders.
The purpose of this study is to determine the safety and tolerability of MS-R001 at escalating doses in patients with diabetic macular edema secondary to diabetic retinopathy
This study will evaluate the clinical efficacy of intra-vitreal injections of Ranibizumab (Lucentis) in the treatment of Diabetic Macular Edema as compared to grid/focal laser.
This study will test whether a new non-invasive technique can quickly and precisely measure retinal metabolism (the amount of energy retinal cells use). The retina is the part of the eye that sends information to the brain. Participants in current NEI studies who have age-related macular degeneration (AMD), diabetic retinopathy, or von Hippel-Landau disease may be eligible for this study. Healthy volunteers will participate as controls. Patients with AMD must be 60 years of age or older; those with VHL disease or diabetic retinopathy must be 18 or older. Participants undergo the tests and procedures required in the NEI study in which they previously enrolled. In addition, for the current study, they undergo metabolic mapping. For this procedure, the subject's eyes are dilated, and different amounts of low-level light are shone into the eye to see how different cells respond with changes in metabolism. Measurements are taken while the subject breathes room air and while he or she breathes medical grade oxygen for about 1 minute. The entire procedure takes about 15 minutes.
To evaluate the effect of intravitreal bevacizumab on the course of diabetic retinopathy in cases with the signs of active progressive PDR
To Demonstrate that indigenous green laser produces similar treatment effect on the retina when compared with already available green laser.
The purpose of the study is to evaluate the safety and efficacy of 2.5 mg of intravitreal bevacizumab in one eye, versus panretinal photocoagulation in the contralateral eye, for the treatment of patients with untreated symmetric proliferative diabetic retinopathy.
The purpose of this research is to evaluate optical coherence tomography (OCT) and FDA approved device used to image diseases of the eye. The ultra-high resolution OCT is a non-significant risk device used in this study. Optical Coherence Tomography may be useful for early diagnosis and monitoring of different types of eye diseases.
The purpose of this research study is to evaluate an investigational system that may allow doctors to show images of the different parts inside the eye that show greater detail than current equipment can produce.
The purpose of this study is to compare the effect of two antihypertensive drugs on retinal vessel diameter in young type 1 diabetics. The retinal vessel analyzer (RVA) was used to investigate how the drugs affected vessel diameter, when the subjects were exposed to an increase in blood pressure, induced by isometric muscle contraction and when they were stimulated by flickering light.
