title: Intravitreal bevacizumab for treatment of chronic central serous chorioretinopathy.
abstract: OBJECTIVE
  To evaluate the short-term safety and efficacy of intravitreal bevacizumab for the treatment of intraretinal or subretinal fluid accumulation secondary to chronic central serous chorioretinopathy (CSC).
  
  
  METHODS
  Twelve patients were treated with intravitreal injections of 2.5 mg bevacizumab at 6- to 8-week intervals until intraretinal or subretinal fluid resolved. Observation procedures were Early Treatment Diabetic Retinopathy Study best-corrected visual acuity (BCVA), ophthalmic examination, and optical coherence tomography (OCT), performed at 6- to 8-week intervals. Fluorescein angiography was performed at baseline visit and thereafter depending on clinical and OCT findings. Multivariate analysis of variance with repeated measures was used to calculate a statistical significance of change in BCVA and mean central retinal thickness, which were the main outcome measures. SAS statistical software was used for analyses.
  
  
  RESULTS
  Patients received 2-/+1 intravitreal injections of bevacizumab on average during a follow-up of 24-/+14 weeks. Mean BCVA increased by 2-/+2 lines; the change in BCVA (logMAR) was significant (p<0.02). Mean central retinal thickness decreased significantly over follow-up (p<0.05), with 6 patients (50%) showing complete resolution of subretinal fluid.
  
  
  CONCLUSIONS
  Anatomic and functional improvement following intravitreal bevacizumab injections suggest that vascular endothelial growth factor (VEGF) may be involved in fluid leakage in patients with chronic CSC. The results suggest a possible role for anti-VEGF agents in the treatment of chronic CSC. Further evaluation of intravitreal bevacizumab for chronic CSC in controlled randomized studies is warranted.
