Active clinical trials for "Macular Degeneration"

Age related macular degeneration is the leading cause of blindness for people over 50 in the western world. Blood vessels which start to grow form a lesion in the back of the eye. Verteporfin may stabilize the disease, by closing the blood vessels. This study will assess the efficacy and safety of verteporfin in patients with occult only lesions.

This study evaluates the tolerability and safety of 3 months treatment with PTK787 tablets given daily. It also explores the efficacy of the compound in patients with wet age-related macular edema. In Cohort 1 verteporfin/PDT is the active control. The protocol was amended to reflect the current standard of care for AMD. As a result, ranibizumab is the active control for Cohort 2.

This study will examine whether taking the vitamin lutein changes lutein blood levels. Lutein, vitamin C, vitamin E and beta-carotene may be useful in treating the eye disease age-related macular degeneration, but more information is needed to support this. Age-related macular degeneration can significantly impair the ability to read, drive, and carry out daily activities. It is the most common cause of vision loss in people over age 60. Lutein a carotenoid that occurs naturally in the retina (the back part of the eye), especially the macula-the part of the retina that is important for fine, detailed vision. Men and women 60 years of age and older, with or without age-related macular degeneration, may be eligible for this study. Candidates will undergo the following tests: Medical history and physical examination. Eye examination-Includes evaluation of visual acuity, measurement of eye pressure, examination of the lens, retina, pupils and eye movements, and photographs of the eye. Visual field study-Examines the ability to see objects in the periphery. The subject looks at a target on a screen and indicates when lights that appear in other places on the screen are visible. Flicker photometry-The subject looks at a flashing light and turns a knob until the light stops flashing. Blood tests-To measure blood levels of lutein and other carotenoids, liver function, cholesterol and triglycerides. Participants will be randomly assigned to take one of three dosages of lutein (2.5 milligrams, 5 milligrams or 10 milligrams) for 6 months and will be examined at follow-up visits scheduled 1, 3, 6, 9 and 12 months after starting lutein. During these visits, many of the exams described above will be repeated to evaluate the effects of lutein treatment on the eye.

To compare the efficacy and comfort of two FDA approved pre-injection antiseptics when used for intravitreal injections.

A Phase I Clinical Trial for BAT5906(single-dose;for injection) on Safety and Pharmacokinetics for Patients with Age-related macular degeneration.

The primary objectives of the study are to determine the safety of high-dose aflibercept (hereafter referred to as HD) and to determine if HD provides greater intraocular pharmacodynamic (PD) effect and/or longer duration of action compared to intravitreal aflibercept injection (hereafter referred to as IAI).

The purpose of this study is to compare the efficacy and safety of ABP 938 versus Aflibercept (Eylea®) in the treatment of neovascular age-related macular degeneration. Subjects will be randomized in a masked 1:1 ratio to receive 2 mg (0.05 mL) of either ABP 938 (Treatment Group A) or aflibercept (Treatment Group B) administered by intravitreal (IVT) injection.

Investigate the effectiveness and safety of pars plans vitrectomy, with internal limiting membrane peeling for cases of myopic traction maculopathy

This study proposes to use a new instrument (AO-OCT/AF: adaptive optics - optical coherence tomography/autofluorescence) combined with a data processing method to image the retinal pigment epithelium (RPE) of the eye in normal subjects and in subjects with age-related macular degeneration. (AMD). While currently there is no cure, with early diagnosis, vision loss can be slowed. The technology being developed for this project will be the first imaging modality that can provide both structural and molecular information about the retina in vivo and in 3D.

The purpose of this clinical trial is to evaluate the safety and clinical effectiveness of intravitreal bevacizumab (Lumiere®) in the single-dose form, for the treatment of patients with wet AMD.
