Filter by:This study will evaluate the safety and efficacy of the intravitreal implant of dexamethasone for the treatment of macular edema associated with branch retinal vein occlusion.
Othera Pharmaceuticals' Othera (OT)-551 antioxidant eye drop has the potential for chronic treatment of the dry form of age-related macular degeneration. This pilot study of up to 10 eye drop tolerant participants with bilateral geographic atrophy is designed to characterize the effect of 0.45% concentration of OT-551 eye drops given 3 times a day on the progression of geographic atrophy area over a two-year period. Participants will have one eye randomized to receive the eye drop and the fellow eye will be observed only.
Randomized controlled clinical trial of periocular corticosteroids as adjunctive therapy to photodynamic therapy (PDT) for patients with neovascular age-related macular degeneration (AMD). Patients undergoing PDT are randomized to either a periocular corticosteroid injection with 40 mg of triamcinolone acetonide or observation just prior to PDT. Patients are followed for 6 months. Primary outcome is leakage from choroidal neovascularization (CNV) at 3 months on fluorescein angiography.
This study examined whether the anti-inflammatory medicines infliximab, sirolimus or daclizumab, when given with a participant's current therapies, would prevent the growth of new blood vessels in the eye in participants with age-related macular degeneration (AMD). Participants 55 years of age and older with AMD and drusen larger than 63um may be eligible for this study. Vision in the study eye was between 20/20 and 20/400. Participants were randomly assigned to one of three treatments - infliximab, sirolimus, or daclizumab - or to observation only. In addition, participants may have been treated by their ophthalmologist as needed for their AMD. Infliximab and daclizumab were given intravenously (through a vein); infusions were given at enrollment in the study, then at 2 weeks, and then monthly. Sirolimus was a pill that was taken every other day for the duration of the study. At 6 months, participants were evaluated to see whether continuing treatment would be beneficial. In addition to treatment or observation, participants underwent the following procedures: Physical examination at enrollment and 6 months. Photographs of the back of the eye, fluorescein angiography, indocyanine green angiography and measurement of retinal thickness at enrollment and months 1, 3 and 6. - Fluorescein angiography evaluated the eye's blood vessels. A yellow dye was injected into an arm vein and traveled to the blood vessels in the eyes. Pictures of the retina were taken using a camera that flashed a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating possible blood vessel abnormality. - Indocyanine green angiography identified feeder vessels that may have supplied abnormal blood vessels. This procedure is similar to fluorescein angiography, but uses a green dye and flashes an invisible light. - Optical coherence tomography measures retinal thickness. This test shines a light into the eye and produces cross-sectional pictures of the retina. These measurements are repeated during the study to determine whether retinal thickening is getting better or worse, or staying the same. Tuberculin skin test and chest x-ray at enrollment and 6 months. Blood tests at enrollment and months 1, 3 and 6.
The purpose of this study was to evaluate the effect of the dose concentration and administration frequency of Anecortave Acetate (AA) on visual acuity (VA) and lesion size when administered by posterior juxtascleral depot (PJD) every 3 months (AA 15 mg) or 6 months (AA 15 mg, AA 30 mg) in patients with exudative age-related macular degeneration (AMD).
Ranibizumab is derived from a murine monoclonal anti- vascular endothelial growth factor (VEGF) antibody and can penetrate through the many retinal cell layers following intravitreal injection. The present study is directed towards the assessment of ranibizumab administered on the same day in combination with verteporfin in patients with subfoveal CNV secondary to ARMD
Open-label Multicenter, Phase I/II Study comprising three phases (single dose, multiple dose and extension phase), Assessing the Safety and Efficacy of Ranibizumab (RFB002) in Japanese Patients With Subfoveal Choroidal Neovascularization (CNV) Secondary to Age-related Macular Degeneration (AMD).
The objective of this research program is to improve diagnosis and treatment monitoring of ophthalmic disease by improving diagnostic ultrasound techniques. The program explores the use of novel signal and imaging processing techniques towards this end.
The macula is the site of central vision within the retina. The retina is oxygenated by the underlying choroid. These tissues are less than 1 mm thick in total. While optical techniques can reveal much about the structure of the retina, ultrasound allows imaging of the choroid and deeper tissues. This study will investigate use of high frequency (20 MHz) ultrasound for imaging of the retina and choroid in patients with age-related macular degeneration, a prime cause of blindness. The investigation will involve use of novel post-processing methodologies to achieve maximum resolution of the fine tissue structures involved in this disease.
The study will test if the efficacy and safety of an alternative dosing regimen is as effective as monthly injections.
