Abstract

Objective—To compare rates of retinal detachment (RD) post phacoemulsification in American Bichons Frises with and without prophylactic retinopexy.

Procedures—Medical records of 54 Bichons Frises undergoing phacoemulsification with or without prophylactic retinopexy between 2003–2013 in one or both eyes were reviewed from five Midwestern university veterinary teaching hospitals. Inclusion criteria were pre-operative ERG, at least 6 months of follow up post phacoemulsification, and absence of pre-existing RD as determined by ophthalmic examination and/or ultrasound. Statistical analyses used chi-squared and Wilcoxon rank-sum tests and Wilson confidence intervals with the p value

Results—Phacoemulsification was performed without retinopexy in 79 eyes (42 dogs, non-PR group) and with prophylactic retinopexy in 23 eyes (12 dogs, PR group). Incidence of diabetes mellitus was 10/42 and 3/12 in the non-PR and the PR groups respectively (p=0.93). Intraocular lens implantation was performed in 40/42 non-PR dogs and 11/12 PR dogs, (p=0.63, 73/79 versus 21/23 eyes). At final re-examination, RD occurred in 4/79 eyes without retinopexy, compared to 0/23 RD in the retinopexy group. There was no statistically significant difference in RD rates between the two groups (p=0.27)

Conclusions—These data provide no statistical evidence to support prophylactic retinopexy in Bichon Frises. Due to the low rate of retinal detachment following phacoemulsification without prophylactic retinopexy, the procedure appears to offer limited benefit to offset cost, procedural risk and risk of extended or repeated anesthesia in Bichons Frises.
