title: Photodynamic therapy as treatment of chronic idiopathic central serous chorioretinopathy.
abstract: OBJECTIVE
  Chronic idiopathic central serous chorioretinopathy (ICSC) is characterized by persistent, recurrent, and multifocal serous detachments of the neurosensory retina. Our objective is to evaluate the visual and anatomical outcomes of patients who underwent photodynamic therapy (PDT) with Verteporfin for chronic ICSC.
  
  
  METHODS
  A retrospective review of 13 eyes of 12 patients (mean age 55, range 45-66 years) treated with PDT for chronic ICSC between June 2004 and January 2008 was conducted. Two eyes that subsequently developed choroidal neovascularization were excluded. Best corrected visual acuity (BCVA) and clinical examination prior to PDT and at most recent follow-up were recorded. Fluorescein angiography (FA) and optical coherence tomography (OCT) findings prior to and following treatment were reviewed.
  
  
  RESULTS
  Mean duration of symptoms prior to PDT was 26.7 months (range 3-108 months). Mean follow-up duration was 21.9 months (range 2-42 months). BCVA improved in seven of eleven eyes (mean 1.7 lines, range 1-3 lines), two eyes remained unchanged, and two eyes worsened. Complete resolution of serous detachment was demonstrated in 9 of 11 eyes by FA or OCT and 10 of 11 eyes by clinical examination. One eye showed a reduction in serous detachment by OCT and clinical exam. Three eyes required two treatments for recurrent serous detachment following initial treatment.
  
  
  CONCLUSIONS
  Our data suggest that PDT leads to resolution of serous detachments and visual improvement in patients with chronic ICSC. Further follow-up would be prudent to assess the long-term outcomes and safety in this patient population.
