This study will evaluate the safety and efficacy of an intravitreal implant of dexamethasone for the treatment of macular edema associated with retinal vein occlusion.
This study will evaluate the safety and efficacy of an intravitreal implant of dexamethasone for the treatment of macular edema associated with retinal vein occlusion.
The trial will test the hypothesis that an intravitreal injection of triamcinolone is safe and efficacious for patients with clinically significant diabetic macular oedema that is recalcitrant to conventional laser therapy
This open label extension will treat all the eyes of study participants with active study medication (intravitreal triamcinolone) as well as standard laser treatment where appropriate. The specific aims will be to test the following hypotheses: - That intravitreal triamcinolone for diabetic macular oedema that persists or recurs after laser treatment remains efficacious over five years - That intravitreal triamcinolone for diabetic macular oedema that persists or recurs after laser treatment retains a manageable and acceptable safety profile over five years
This study is likely to identify an improved and economical treatment for diabetic macular oedema, one of the commonest causes of blindness both in Australia and the rest of the world.The specific aims of the study are to test the following hypotheses: - That intravitreal triamcinolone followed by laser treatment results in a greater improvement in visual acuity than placebo followed by laser treatment of eyes with macular oedema secondary to diabetes; - That intravitreal triamcinolone followed by laser treatment results in greater degree of resolution of macular oedema than placebo followed by laser treatment of eyes with macular oedema secondary to diabetes; - That intravitreal triamcinolone followed by laser treatment results in a reduced requirement for further laser treatment to control diabetic macular oedema than placebo followed by laser treatment; - That intravitreal triamcinolone followed laser has a manageable and acceptable safety profile in eyes with diabetic macular edema.
The purpose of this study is to investigate the safety and tolerability of three dose strengths of the study drug in subjects with post cataract extraction macular edema.
The purpose of the study is to test the hypothesis that oral administration of ruboxistaurin will reduce the occurrence of sustained moderate visual loss (SMVL) in patients with clinically significant macular edema. SMVL is defined as a 15 letter or more decrease from baseline in best-corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity that is sustained for the patient's last 6 months of study participation. The SMVL data from this study will be combined with the SMVL data from Study B7A-MC-MBDL for the purpose of comparing ruboxistaurin to placebo.
The purpose of this study is to determine whether denufosol tetrasodium (INS37217) Intravitreal Injection is well tolerated and has the potential to treat uveitis associated macular edema.
This study will compare the safety and effectiveness of two treatments-injections of triamcinolone acetonide into the eye vs. standard laser therapy-for macular edema (swelling in the center of the retina) that is caused by blockage in a retinal blood vessel. Edema caused by blockage in a large vessel is called central retinal vein occlusion (CRVO). Edema caused by blockage in a smaller vein is called branch retinal vein occlusion (BRVO). Triamcinolone acetonide is a steroid drug that reduces swelling; the Food and Drug Administration has approved it for injection into joints and muscles to treat inflammatory conditions. Patients 18 years of age and older with macular edema due to CRVO or BRVO of between 3 and 18 months' duration may be eligible for this study. Candidates are screened with a medical history, blood pressure measurement, and urine pregnancy test for women who can become pregnant. Screening also includes the following procedures: - Eye examination to assess visual acuity and eye pressure, and to examine the cornea, lens, and retina. The pupils are dilated with drops for this examination. - Fluorescein angiography to evaluate the eye's blood vessels. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina are taken using a camera that flashes 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. - Optical coherence tomography to measure retinal thickness. The eye is examined with a machine that produces cross-sectional pictures of the retina. The patient is seated in front of a machine and looks at a pattern of flashing and rotating red and green lights, first with one eye and then with the other. - Fundus photography to help evaluate the status of the retina and changes that may occur in the future. Photographs of the retina are taken using a camera that flashes a bright light into the eye. Participants are randomly assigned to receive triamcinolone injections or standard treatment. Triamcinolone is given in either a 1-mg or 4-mg dose. Standard treatment for CRVO and for BRVO with excessive blood in the retina is observation. Standard treatment for BRVO without excessive blood is laser therapy. Patients with BRVO who do not qualify for laser therapy when they enter the study may have it later if blood clears enough to permit treatment. The procedures for triamcinolone injections and laser therapy are as follows: - Triamcinolone acetonide: The eye is numbed with anesthetic drops and the study drug is injected into the vitreous, the jelly-like substance located between the back of the lens and the retina. Patients apply antibiotic drops at home for 3 days following the procedure. - Laser treatment: The eye is numbed with anesthetic drops and a special contact lens is placed on the eye during the laser beam application. All patients are followed every 4 months for 3 years. Additional visits may be scheduled if needed. Patients who receive triamcinolone injections are also examined within 1 week of each injection and 1 month after each injection. At the 4-month visits patients undergo repeat eye examination and fundus photography. Optical coherence tomography is done at some visits, and fluorescein angiography is repeated at months 4, 12 and 24. Blood pressure is measured at months 12, 24 and 36. Patients may be retreated with triamcinolone injections or laser therapy as often as every 4 months, depending on their response to treatment.
