Filter by:The objective of this study is to determine if combination therapy (reduced-fluence Visudyne followed by Lucentis [within 2 hours] or either of two regimens of reduced-fluence Visudyne followed by Lucentis-Dexamethasone triple therapy [within 2 hours]) reduces retreatment rates compared with Lucentis monotherapy while maintaining similar vision outcomes and an acceptable safety profile.
Our aim in this study is to find out if we can locate the similar reduction in the recruitment of macrophages, remodeling of vasculature and do they correlate in the number and area of the islets in pancreas as in the mouse model.
In this pilot study the researchers will evaluate the safety and efficacy of 50% reduced fluence PDT combination therapy with ranibizumab. The researchers hope to gain information regarding the use of reduced fluence PDT combination therapy. The information gained from this pilot study may prompt further definitive studies comparing the safety and efficacy of both standard fluence PDT combination therapy, reduced fluence PDT combination therapy, and ranibizumab monotherapy. The study will compare the use of combination therapy with ranibizumab and verteporfin PDT to ranibizumab alone in patients with exudative age-related macular degeneration (AMD). All patients will receive three consecutive monthly treatments with ranibizumab. Patients will be randomized 1:1:1 to 3 groups. Patients randomized to group 1 will receive only ranibizumab. Patients randomized to group 2 will also receive one treatment with reduced fluence (50% fluence) verteporfin PDT at day 0. Patients randomized to group 3 will also receive one treatment with standard fluence verteporfin PDT. All patients will also be evaluated for possible retreatment with ranibizumab and verteporfin PDT according to established criteria. Thirty patients will be recruited from one U.S. sites. Randomization will occur at the time of entry into the study. Follow-up will continue until month 12 (from day 0) in all subjects.
Purpose: To investigate the efficacy of photodynamic therapy with verteporfin for the treatment of patients with corneal neovascularization. Design: Prospective, non-comparative case series. Participants: Eighteen eyes of 18 patients with stable corneal neovascularization who were refractory to conventional treatment. Methods: The patients were treated with photodynamic therapy with verteporfin (6 mg/m2). Five patients were treated following penetrating keratoplasty, and 2 patients were treated before penetrating keratoplasty. Best corrected visual acuity and anterior segment photography were performed before and after treatment. The length of cumulative blood vessels and area of corneal neovascularization were measured. Main outcome measures: Vascular occlusion, best corrected visual acuity, cumulative blood vessel length, and corneal neovascularization area.
This study will evaluate efficacy and safety for monthly ranibizumab 0.5 mg intravitreal injections in Asian patients with subfoveal choroidal neovascularization secondary to age-related macular degeneration.
This study evaluated the effect of combination therapy with verteporfin photodynamic therapy and ranibizumab on visual acuity and anatomic outcomes compared to ranibizumab monotherapy and the durability of response observed in patients with choroidal neovascularization secondary to age-related macular degeneration.
This pilot study is designed to evaluate the safety and efficacy of intravitreal ranibizumab used in combination with verteporfin photodynamic therapy (Visudyne®) compared to ranibizumab monotherapy for the treatment of subfoveal CNV secondary to AMD
The purpose of this research study is to compare different timing therapies of Verteporfin with Bevacizumab to treat choroidal neovascularization (CNV) due to age-related macular degeneration (AMD).
The purpose of this study is to determine the sensitivity of the optical coherence tomography (OCT) test in detecting neovascular AMD in eyes at high risk for CNV development. In order to test this hypothesis, we are conducting a multi-center clinical study at four participating clinical centers. A total of 227 participants will be enrolled. Participants will be followed-up for a period of two years, or until CNV develops in the study eye for which treatment is recommended, to determine the occurrence of CNV. The fundamental design principles of the study are simplicity and parsimony.
This study will quantify the intraocular pressure elevation in the immediate time period following intravitreous injection. With more widespread use of intravitreous injections in patients that may require several injections per year, it is important to document the sudden increase in intraocular pressure, including the maximum intraocular pressure and the time required for the intraocular pressure to return to baseline. This data may be useful in stimulating additional studies to evaluate the long term ocular effects of repeated intravitreous injections. We hypothesize that the intraocular pressure increases significantly following intravitreous injection and then returns to baseline during the initial thirty minutes following ranibizumab injection.
