title: Urrets-Zavalia syndrome as a complication of argon laser peripheral iridoplasty.
abstract: OBJECTIVE
  To report on 8 patients who developed prolonged mydriasis after argon laser peripheral iridoplasty (ALPI).
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  A review of the charts of 8 patients with persistent occludable angles after laser iridotomy who developed mydriasis after undergoing ALPI.
  
  
  RESULTS
  12 eyes of 8 patients (mean age 50.2, standard deviation 6.9, range 40-61 years) developed persistent dilatation. 7 of 8 patients had plateau iris syndrome. Only one patient had a decrease in visual acuity. Intraocular pressure increased only in 1 eye and remained stable or decreased in the others. Of the 8 patients, 7 had blurred vision, 2 had photophobia, 4 had glare and 1 had discomfort. The pupillary response to pilocarpine instillation was minimal or absent. Mydriasis eventually resolved in all eyes without treatment.
  
  
  CONCLUSIONS
  ALPI can be complicated by mydriasis unresponsive to pilocarpine. Mydriasis and accompanying symptoms resolved spontaneously within 1 year in most patients.
