title: Acetazolamide-induced bilateral choroidal effusion following insertion of a phakic implantable collamer lens.
abstract: OBJECTIVE
  To present the case of a 28-year-old man with acetazolamide-induced bilateral choroidal effusion after uneventful surgery of the second eye in delayed sequential bilateral insertion of an implantable collamer lens for hyperopia.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  Surgery of the left eye was uneventful, and the implantable collamer lens was implanted 3 weeks later in the right eye. Twenty-four hours after surgery, the patient presented with bilateral shallow anterior chamber, vault 0, and myopic shift (-8 diopters) in both eyes. B-scan ultrasound showed choroidal thickening in both eyes, which was consistent with choroidal effusion syndrome. A causal relationship was suspected with oral acetazolamide, which had been prescribed after surgery. When the drug was stopped, the condition improved slowly and resolved completely within 5 days.
  
  
  CONCLUSIONS
  Choroidal effusion should be included in the differential diagnosis of shallow anterior chamber after implantation of an implantable collamer lens.
