Ranibizumab in Hemorrhagic Choroidal Neovascularization Trial
This research is being done to look at the effects of an experimental drug, ranibizumab, on a condition called "predominantly hemorrhagic subfoveal choroidal neovascularization (CNV)" due to wet age-related macular degeneration.
A predominantly hemorrhagic CNV lesion is diagnosed when at least 50% of the choroidal neovascular lesion is occupied by blood under the retina. We want to find out if injections of ranibizumab into the eye will help patients with this condition.

- Number of Subjects Avoiding 15 or More Letter Loss of Best Corrected Visual Acuity From Baseline to 12 Months on an Early Treatment Diabetic Retinopathy Study (ETDRS) Visual Acuity Chart Measured at 4 Meters. [ Time Frame: 12 months ] [ Designated as safety issue: No ]Visual acuity measured prior to first treatment with ranibizumab and at 12 months following the first treatment were compared for each subject enrolled in the study. The 12 month follow-up visual acuity was subtracted from the baseline visual acuity. Avoiding a 15 or more letter loss in visual acuity was considered a successful outcome.
- Retinal Changes on Funduscopy [ Time Frame: 12 months ] [ Designated as safety issue: No ]
- Retinal Thickness Measured by Optical Coherence Tomography (OCT) [ Time Frame: 12 months ] [ Designated as safety issue: No ]
- Fluorescein Leakage on Fluorescein Angiography [ Time Frame: 12 months ] [ Designated as safety issue: No ]
- Number of Subjects Experiencing Complications Related to Drug or Its Administration [ Time Frame: 12 months after last injection ] [ Designated as safety issue: Yes ]
Potential complications included:
- Deterioration of best-corrected visual acuity by 3 or more lines
- Development of intraocular inflammation
- Development of elevated intraocular pressure
- Development of other ocular or systemic adverse effects.
Subjects were monitored for potential drug-related ocular adverse effects: intraocular inflammation (uveitis), endophthalmitis, central retinal vein occlusion, transient elevation of IOP, acute reduction in the visual acuity, vitreous hemorrhage, injection-site pain, retinal hemorrhage, posterior vitreous detachment, and subconjunctival hemorrhage. Subjects were monitored for potential adverse effects of intravitreal injections: crystalline lens penetration, retinal break and/or detachment, vitreous hemorrhage, inflammation, and infection. Potential systemic adverse effects were captured by monitoring vital functions such as cardiovascular function, nervous system function, renal function, and gastrointestinal function.
