title: Clinical Analysis of 50 Chinese Patients with Aqueous Misdirection Syndrome: a Retrospective Hospital-based Study.
abstract: OBJECTIVE
  To evaluate the efficacy of treatments for aqueous misdirection syndrome and explore possible risk factors influencing prognosis.
  
  
  METHODS
  Data including demographics, initial clinical characteristics and ocular outcomes at follow-up were collected for patients treated for aqueous misdirection syndrome. Main outcome measures were: best-corrected visual acuity (BCVA); intraocular pressure (IOP); number of antiglaucoma medications; recurrence; complications.
  
  
  RESULTS
  Data were available for 50 patients (57 eyes). Final mean BCVA improved significantly and correlated with baseline BCVA (mean follow-up, 34.47±28.65 months). Final mean IOP and mean number of antiglaucoma medications were significantly reduced. Treatment failure rates were higher in patients with significantly higher IOP at baseline and/or shorter axial length. Following pars plana vitrectomy (PPV), recurrence occurred in two of 10 pseudophakic and one of 40 phakic eyes; complications were observed in 12/50 eyes (choroidal detachment, corneal decompensation, retinal detachment, vitreous haemorrhage, hyphaema).
  
  
  CONCLUSIONS
  PPV and laser treatments, augmented by pharmacotherapy, were effective in treating aqueous misdirection syndrome. Surgical intervention should be undertaken early in eyes with higher baseline IOP and/or shorter axial length. Total vitrectomy-zonulectomy-iridectomy is a potential approach for recalcitrant cases.
