title: Half-fluence photodynamic therapy to treat chronic central serous chorioretinopathy: A case series.
abstract: OBJECTIVE
  To evaluate the efficacy and safety of half-fluence photodynamic therapy (PDT) in treating chronic central serous chorioretinopathy (CSC) in Omani population.
  
  
  METHODS
  A Retrospective chart review of all patients with chronic CSC treated with half-fluence PDT from November 2009 to December 2010 was carried out. Recorded parameters included best-corrected visual acuity, findings of clinical examination, results of fluorescein angiography and optical coherence tomography at baseline and during follow-up visits after treatment.
  
  
  RESULTS
  Six eyes (of five Omani patients) with chronic CSC, of at least 9 months duration, were treated with half-fluence PDT. All eyes showed a complete resolution of CSC within 1 month following treatment. Four eyes showed visual improvement and two had unchanged stable vision. No complications from the treatment were noticed during the follow-up visits.
  
  
  CONCLUSIONS
  Half-fluence PDT to treat chronic CSC in Omani population is a promising treatment that results in both structural and functional improvement.
