Active clinical trials for "Choroidal Neovascularization"

This study was conducted to evaluate the efficacy and safety of 0.5 mg ranibizumab in adult and adolescent patients with visual impairment due to choridal neovascularization (CNV).

The investigators hypothesize that it is safe and effective to treat patients with choroidal neovascularisation (abnormal blood vessels growing under the retina) secondary to causes other than age related macular degeneration (AMD) and pigment epithelial detachments (blisters of fluid under the retina) secondary to AMD with ranibizumab (Lucentis). These groups of patients have to date been excluded from the multicentre trials demonstrating significant benefit of Ranibizumab in the treatment of AMD.

This study will examine the safety and efficacy of pegaptanib sodium in Japanese patients with wet-type age-related macular degeneration (AMD), who benefit further treatment and who want to continue the treatment after completion of the preceding study (A5751010).

This study will test the safety and effectiveness of a fluocinolone implant to treat age-related macular degeneration. This eye disease can severely impair central vision, affecting a person's ability to read, drive, and carry out daily activities. It is the leading cause of vision loss in people over age 60. The fluocinolone implant is a tiny plastic rod with a pellet of the steroid fluocinolone on the end. The pellet slowly dissolves and releases the medication into the fluid in the eye. Vision loss in macular degeneration is caused by the formation of new blood vessels in the choroid-a thin, pigmented vascular layer of the eye behind the retina. These abnormal vessels leak blood under the macula, the part of the retina that determines central vision. Tissue studies show evidence of inflammation in the retinas of patients. This study will test whether the slow release of the steroid fluocinolone directly into the affected part of the eye can prevent or slow further vision loss. Preliminary animal and human studies with fluocinolone implants have shown some benefit in reducing blood vessel growth and improving or stabilizing vision. Patients 50 years of age and older with age-related macular degeneration may be eligible for this study. Study patients will be randomly assigned to one of two treatment groups. One will receive a 0.5-mg dose implant; the other will receive a 2-mg dose implant. Theoretically, the implants can release the medicine for 2 to 3 years. Participants will have a medical history, physical examination and complete eye examination. The latter will include a vision test, eye pressure measurement, examination of the pupils, lens, retina, and eye movements. Photographs of the eye will be taken with a special camera. Patients will also undergo fluorescein angiography, a test that takes pictures of the retina using a yellow dye called sodium fluorescein. The dye is injected into the blood stream through a vein. After it reaches the blood vessels of the eye, photographs are taken of the retina. When the above tests are completed, patients will be scheduled for surgery to place the implant. The procedure will be done under either local or general anesthesia. Follow-up visits will be scheduled 1, 2, 4, and 6 weeks after surgery, then at 3 and 6 months after surgery, and then every 6 months until the implant is depleted of medicine or is removed. Several of the exams described above will be repeated during the follow-up period to evaluate the treatment and side effects, if any.

This is a phase III, multicenter, randomized, double masked, sham injection-controlled study of the efficacy and safety of intravitreally administered ranibizumab in subjects with subfoveal choroidal neovascularization secondary to age-related macular degeneration.

The purpose of this study is to compare brolucizumab (RTH258) ophthalmic solution for intravitreal (IVT) injection (6 mg) to aflibercept ophthalmic solution for IVT injection (2 mg) in subjects with untreated active choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) in the study eye.

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 anecortave acetate compared to placebo for maintenance of visual acuity after 24 months of treatment in patients with subfovial choroidal neovascularization (CNV) due to exudative age-related macular degeneration (AMD).

This study will evaluate patients with diagnosis of polypoidal choroidal vasculopathy (PCV) in pachychoroid treated with combined therapy, consisting in photodynamic therapy (PDT) and 3 intravitreal therapy (IVT) of Aflibercept monthly. This is a single center, prospective case-series study. The investigators are going to evaluate Corrected Distance Visual Acuity (CDVA), disease activity, retinal and choroidal thicknesses and number of injection per year, during a twelve month follow up. The aim of this study is to verify if the combined therapy can act on the insult induced by the pachychoroid and on the neovascular lesion itself in this sub-population of patients with PCV in pachychoroid,

To evaluate and compare two individualised ranibizumab treatment regimens, differentiated by the definition of disease activity, which determines the treatment interval until the next injection. The results will be used to generate recommendations about ranibizumab treatment when using an 'inject and extend' approach to maximise patient outcomes, while reducing the need for potentially unnecessary intravitreal injections. This study will also investigate if genotypic expression influences response to intravitreal injections of ranibizumab between the two treatment arms. The study hypothesis is that intravitreal ranibizumab when administered to resolve IRF (and/or SRF >200 μm at the foveal centre) results in visual acuity benefit that is not clinically worse than intravitreal ranibizumab when administered to completely resolve both IRF and SRF in patients with wet AMD
