title: [Effect of mydriasis and accommodation on intraocular pressure and pigment release in patients with the pigment dispersion syndrome].
abstract: OBJECTIVE
  To determine if mydriasis and accommodation affect intraocular pressure (IOP) and pigment release in patients with the pigment dispersion syndrome (PDS).
  
  
  METHODS
  Seventeen patients (34 eyes) diagnosed with PDS were included in the study (10 men and 7 women). Tonometry was performed on all patients before, and at 1 and 2 hours after mydriasis and before, and at 1 and 2 hours after sustained reading. The statistical analysis was performed using the paired T-test.
  
  
  RESULTS
  In both tests the differences in intraocular pressure values were not statistically significant. Pigment liberation occurred in 11.8% of patients after mydriasis but was not associated with an increase in IOP.
  
  
  CONCLUSIONS
  Accommodation during sustained reading did not cause significant pigment release or an IOP rise.
