title: Therapy Rationale for Mineralocorticoid-Receptor Antagonists, Acetazolamide and a Switch of Therapy in Nonresponders in Central Serous Chorioretinopathy.
abstract: To evaluate the efficacy of mineralocorticoid-receptor antagonists in comparison to acetazolamide and observation in the treatment of central serous chorioretinopathy.
  
  
  
  Retrospective, interventional cohort study on 93 patients with acute or chronic central serous chorioretinopathy (37 patients: acetazolamide group, 20 patients: mineralocorticoid-receptor antagonist group, 8 patients: observation group, and 27 patients with a therapy switch between both medications). Main outcome measures were the change in best-corrected visual acuity, subretinal fluid (SRF) volume, central retinal prominence, and highest retinal prominence (HRP) at 12 weeks.
  
  
  
  HRP and SRF volume improved with statistical significance (P ≤ 0.05) after mineralocorticoid-receptor antagonist (P = 0.0000003 for the prominence, P = 0.008 for the volume) and acetazolamide (P < 0.0000001 for the prominence, P = 0.0000007 for the volume) treatment. HRP and SRF volume also improved after observation, but without statistical significance (P = 0.08 for the prominence, P = 0.72 for the volume). Corresponding visual acuity improved significantly in acetazolamide (P = 0.002) and mineralocorticoid-receptor antagonist (P = 0.03) treated patients. Interestingly, HRP and SRF volume in acetazolamide nonresponsive patients improved after switch to mineralocorticoid-receptor antagonists, whereas no benefit was seen in patients switching vice versa.
  
  
  
  Both medical treatments are effective first-line treatment options for central serous chorioretinopathy. In patients who are nonresponsive to acetazolamide, therapy switch to mineralocorticoid-receptor antagonists could be beneficial.
