title: Non-penetrating deep sclerectomy in unilateral open-angle glaucoma secondary to idiopathic dilated episcleral veins.
abstract: OBJECTIVE
  To investigate the efficacy of non-penetrating deep sclerectomy (NPDS) in a secondary open-angle glaucoma case due to dilated episcleral veins, on intraocular pressure and retrobulbar hemodynamics.
  
  
  METHODS
  NPDS was done on a 32-year-old male unilateral open-angle glaucoma secondary to idiopathic dilated episcleral veins.
  
  
  RESULTS
  Except for hyphema and shallow anterior chamber on the first post-operative day, no other complications were observed. Intraocular pressure was 18-20 mmHg during the first six months, without medication or visual loss. Retrobulbar color Doppler imaging showed normal mean and end-diastolic velocities and pulsatility indices of the posterior ciliary and central retinal arteries at end of the first post-operative year.
  
  
  CONCLUSIONS
  NPDS may be an alternative to trabeculectomy in open-angle glaucoma secondary to dilated episcleral veins.
