Objective:
To determine whether photoreceptor outer segments can be found in aqueous humor from dogs with rhegmatogenous retinal detachment (RRD).
Design:
Case series.
Animals:
4 dogs with unilateral RRD, 2 dogs with bilateral RRD, 1 dog with unilateral non-RRD, and 1 dog with glaucoma without retinal detachment.
Procedure:
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.
Clinical Implications:
Photoreceptor outer segments may move into the anterior chamber of eyes with RRD.
