Abstract
This study was performed to describe the outcome of pars plana retinopexy with perfluoro-n-octane (PFO)-silicone oil (SiO) exchange in dogs with rhegmatogenous retinal detachment in Seoul National University Veterinary Medical Teaching Hospital (SNU VMTH) from 2014 to 2017. Nine eyes of 8 dogs were included in this study. Medical records including signalment, history, duration from onset of blindness to surgical intervention, pre-operative findings, duration from surgery to regaining vision, and post-operative complications were evaluated. No eyes were visual before surgery. Duration from onset of blindness to surgical intervention was 2-30 days (median 8 days); duration from surgery to regain vision was 1-14 days (median 6 days); follow-up time was 15-1088 days (median 69 days). Post-operative complications were divided as temporary vs permanent conditions. Temporary complications were corneal ulcer, uveitis, retinal haemorrhage, glaucoma, subconjunctival leakage of SiO, and vitreal haemorrhage. Permanent complications were anterior chamber migration of SiO, retinal degeneration, corneal degeneration, re-detachment, and cataract. Six of 9 eyes regained functional vision, five of which remained visual throughout the follow-up time while the other one lost vision after 3 months because of uveitic glaucoma. In conclusion, pars plana retinopexy with PFO-SiO exchange provided fair outcome in 66.7% cases described in this study.
