title: Photoreceptor outer segments in aqueous humor from dogs with rhegmatogenous retinal detachments.
abstract: OBJECTIVE
  To determine whether photoreceptor outer segments can be found in aqueous humor from dogs with rhegmatogenous retinal detachment (RRD).
  
  
  METHODS
  Case series.
  
  
  METHODS
  4 dogs with unilateral RRD, 2 dogs with bilateral RRD, 1 dog with unilateral non-RRD, and 1 dog with glaucoma without retinal detachment.
  
  
  METHODS
  Aqueous humor samples were fixed in 2% glutaraldehyde and examined by means of transmission electron microscopy.
  
  
  RESULTS
  Outer segments were found in aqueous humor from 7 of 8 eyes with RRD but were not found in aqueous humor from dogs with non-RRD or glaucoma.
  
  
  CONCLUSIONS
  Photoreceptor outer segments may move into the anterior chamber of eyes with RRD.
