title: Early-stage diffuse unilateral subacute neuroretinitis: improvement of vision after photocoagulation of the worm.
abstract: OBJECTIVE
  To evaluate the visual outcome after direct laser photocoagulation of the worm in patients with early-stage diffuse unilateral subacute neuroretinitis (DUSN).
  
  
  METHODS
  We report on four patients with DUSN diagnosed in its early stage, in whom the worm was identified and destroyed by laser photocoagulation.
  
  
  RESULTS
  In all the four cases, resolution of the inflammatory multifocal lesions was achieved within 1 month of treatment. After that period and during follow-up (mean 11.5 months), visual acuity improved in three eyes and remained unchanged in one eye.
  
  
  CONCLUSIONS
  The diagnosis of DUSN in its early stage followed by prompt location and destruction of the worm by photocoagulation may improve vision of affected patients.
