Outcome of retinal reattachment surgery in dogs: a retrospective study of 145 cases.

OBJECTIVE

To summarize the clinical outcomes and complications of pars plana vitrectomy with perfluoro-n-octane (PFO)-silicone oil exchange and endolaser retinopexy for treatment of retinal detachment (RD) in dogs, at one surgical center.

PROCEDURE

Records of 145 dogs (168 eyes) that underwent retinal reattachment surgery (RR) between 2005 and 2009 were reviewed. All surgeries were performed by the same surgeon (SS). Data collected from the medical records included signalment, duration of time from diagnosis of RD to surgical intervention, if prior lensectomy was performed, time from surgery to restoration of vision, and postoperative complications. The data was analyzed to test the effect of breed, prior lensectomy, and time from diagnosis to surgery on visual outcome, tendency for complications, and time of complication onset.

RESULTS

One hundred thirty pure-bred dogs (36 breeds) and 15 mixed-breed dogs were represented. One hundred fifty-five of 168 eyes (92%) were visual after surgery. Six of 155 eyes (3.8%) were visual before the procedure and retained vision; one hundred forty-nine of 155 eyes (96%) were nonvisual before and regained vision afterward. Thirteen of 168 eyes (8%) that were nonvisual prior to the procedure did not regain vision. The most common complications in order of occurrence included: cataract development, silicone prolapse into the anterior chamber, corneal ulceration, retinal degeneration, glaucoma, and uveitis.

CONCLUSIONS

Pars plana vitrectomy with PFO-silicone oil exchange and endolaser retinopexy for treatment of RD in dogs is highly successful and associated with overall good visual outcome.
