Photoreceptor outer segments in aqueous humor from dogs with rhegmatogenous retinal detachments.
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.
