Objective To identify the frequency of vitreous degeneration and its association with ocular comorbidities including cataracts, lens luxation, glaucoma, and retinal detachment. Methods This is a retrospective study of 4217 dogs from the Companion Animal Eye Registry (CAER) that underwent breed screening ophthalmic examinations between 2013 and 2016. The breeds analyzed included the Italian Greyhound, Shih Tzu, Affenpinscher, Bichon Frise, Brussels Griffon, Whippets, and Greyhound. Data collected from CAER included age, gender, number of examinations, and whether vitreous degeneration, along with cataracts, lens luxation, glaucoma and/or retinal detachment were present in either or both eyes. Results The study found that breed and age are significant drivers for developing VD. Italian Greyhounds, Brussels Griffons, and Shih Tzus have a significantly higher likelihood of VD compared to the negative control breed, the Greyhound. Additionally, with every 1‐year age increase, there is a 24% higher likelihood of developing VD. However, no association was identified between vitreous degeneration and cataracts, lens luxation, glaucoma, or retinal detachment. Conclusions While the study found that breed and age were significant drivers for developing VD, no association was found between VD and the other ocular comorbidities examined.

OBJECTIVE To determine the prevalence of bacteriuria (ie, a positive microbial culture result for ≥ 1 urine sample) in dogs with chronic kidney disease (CKD) and characterize findings of subclinical bacteriuria (SBU), bacterial cystitis, or pyelonephritis in these patients. DESIGN Retrospective, observational study. ANIMALS 182 dogs. PROCEDURES Medical records from January 2010 through July 2015 were reviewed to identify dogs with CKD that underwent urinalysis and urine microbial culture. Signalment, clinicopathologic data, stage of CKD according to previously published guidelines, results of urinalysis and urine culture, and abdominal ultrasonographic findings were recorded. Dogs with positive urine culture results were categorized as having SBU, bacterial cystitis, or pyelonephritis on the basis of these data. Prevalence of bacteriuria was calculated. Associations between CKD stage, presence of bacteriuria, and diagnosis category were analyzed statistically. RESULTS 33 of 182 (18.1%) dogs (40/235 [17.0%] urine samples) had positive culture results. All dogs received antimicrobials on the basis of culture and susceptibility test findings. Most positive culture results (18/40 [45%] samples) were found for dogs with SBU, followed by dogs with pyelonephritis (16/40 [40%]) and cystitis (6/40 [15%]). Escherichia coli was the most frequently observed isolate (29/40 [73%] cultures from 25/33 dogs). The CKD stage was not associated with presence of bacteriuria or diagnosis category. CONCLUSIONS AND CLINICAL RELEVANCE The prevalence of positive urine culture results in dogs with CKD was lower than that reported for dogs with some systemic diseases that may predispose to infection. Prospective research is needed to assess the clinical importance of SBU in dogs with CKD.

Objective To compare outcomes of surgical intervention and nonsurgical management of canine cataracts. Methods Records of patients examined for cataracts from January 2007 to February 2018 were divided into two groups: nonsurgical and surgical. The nonsurgical group was further subdivided based on whether the decision not to pursue surgery was elected by owners, or based on ophthalmologist's advice. Inclusion criteria included 6 months of follow‐up. Success in the nonsurgical group was defined as a comfortable eye with no potentially painful complications, and success in the surgical group additionally required vision. Time‐to‐failure (complications) was assessed with Cox proportional hazards models. Results A total of 72 eyes (41 dogs) were included in the nonsurgical group, and 126 eyes (67 dogs) were surgically treated. There was no difference in gender or age; however, the surgical group had significantly more diabetic eyes (56.3% vs 15.3%; P < .001) and patient eyes with longer follow‐up times (median 37.6 months vs 22.1 months; P < .001) than the nonsurgical group. There was no statistically significant difference in complication rates between the nonsurgical group (15/72 [20.8%]) and the surgical group (23/126 [18.3%]; HR: 2.22 [0.97, 5.0]; P = .060). However, the complication rate in the ophthalmologist‐led nonsurgical group was significantly greater than in the owner‐led nonsurgical group (P = .019) and the surgical group (P = .002). Conclusions When using relevant outcomes, whether or not a cataractous eye has surgery does not affect long‐term complications; additionally, nonsurgical eyes that are poor surgical candidates have a higher complication rate than eyes deemed suitable for phacoemulsification for which owners elected not to pursue cataract surgery.
