The efficacy of intravitreal bevacizumab for idiopathic central serous chorioretinopathy.

Background: To evaluate the efficacy of intravitreal bevacizumab injection in the treatment of central serous chorioretinopathy (CSC). Methods: In a prospective interventional case series, 40 eyes of 40 patients with idiopathic CSC at least 3 months in duration were included. Patients were treated with once or twice intravitreal bevacizumab injections initially and completed at least 12 months follow-up. Main outcomes measures were the resolution of neurosensory detachment, best-corrected visual acuity, and findings on fluorescein and indocyanine green angiography. Results: Thirty-three of 40 eyes (82.5%) showed complete absence of subretinal fluid at the macula within 3 months following initial intravitreal bevacizumab injection. Eyes exhibiting resolution of subretinal fluid revealed improvement in fluorescein and indocyanine green angiographic findings. The rate of intense hyperfluorescence on indocyanine green angiography was higher in eyes exhibiting resolution of subretinal fluid than eyes exhibiting incomplete absorption of subretinal fluid after intravitreal bevacizumab (72.7 and 28.5%, respectively, p = 0.039). Conclusions: Intravitreal bevacizumab injections generally resulted in anatomic improvement for CSC and may constitute a therapeutic option in CSC. The effect after intravitreal bevacizumab injection for CSC might be related to the hyperfluorescence on indocyanine green angiography. [ABSTRACT FROM AUTHOR]
