title: Pigmentary glaucoma accompanied by Usher syndrome.
abstract: OBJECTIVE
  To report a case of pigmentary glaucoma (PG) accompanied by Usher syndrome.
  
  
  METHODS
  Case report.
  
  
  METHODS
  The results were presented after standard ocular examination, visual field test, anterior segment and fundus photography, electroretinography, and otolaryngology consultation were conducted.
  
  
  RESULTS
  Typical retinitis pigmentosa, flat electroretinography, congenital sensorineural hearing loss, high intraocular pressure, Krukenberg spindle, iris concavity, radial iris transillumination defect, severe pigment deposition on the trabecular meshwork, and glaucomatous optic nerve damage were indicative of PG accompanied by Usher syndrome.
  
  
  CONCLUSIONS
  In some rare cases, PG may coexist with Usher syndrome. Common findings of Usher syndrome, including night blindness, impaired vision, visual field defects, and retinal changes may distract the clinician from considering the diagnosis of glaucoma. Such association should be borne in mind to make a timely diagnosis and treatment possible.
