研究概览
简要总结
The purpose of this study is to examine the effects of Lucentis for active Central Serous Chorioretinopathy.
详细描述
This is an open-label, Phase I study of intravitreally administered ranibizumab in subjects with unresolving CSC and subfoveal fluid. Patients will be evaluated at baseline with ophthalmic examination, fluorescein angiography, optical coherence tomography, and color photography. Subjects will receive open-label intravitreal injections of 0.5 mg ranibizumab administered every 28 days (± 2 days) for 3 injections. Thereafter they are to be evaluated every month until month 12. Treatment will be administered to patients if there is presence of active leakage as determined by fluorescein angiography or persistence presence of sub retinal fluid upon OCT examination at that monthly visit.

- •Any untreated rhegmatogenous retinal detachment.
- •A visual acuity of worse than 20/400 in the fellow eye.
- •Unwilling or unable to follow or comply with all study related procedures.
