“…10 It is generally considered that approximately 10% of dogs presenting with distichiasis require surgical treatment. 13 Different surgical procedures were performed to treat distichiasis in our population of dogs, which were consistent with the techniques described in the literature. The number of dogs that underwent each surgical procedure was small, precluding statistical analysis and comparison of outcomes between the procedures.…”

“…All of these breeds were previously described as being predisposed to distichiasis. 4,5,13 In previous studies, the prevalence of distichiasis in these breeds was extracted from the data obtained through national Hereditary Eye Examination Schemes 2,5 ; therefore, the results cannot be extended to the general population. A prevalence of 49.31% (394/799) in English cocker spaniels was previously reported in Denmark, 5 far exceeding the prevalence of 12.2% (20/164) that we found in our study.…”

“…When the aberrant hairs are considered a source of ocular discomfort or the cause of corneal lesions, they can be removed via multiple surgical treatment options, including temporary manual epilation, eversion of the eyelid margin, and destruction or removal of the distichia follicle via cryosurgery, electroepilation, thermal electrocautery, or partial tarsal plate excision. [10][11][12][13] This study aimed to elucidate the epidemiological factors and clinical impact of distichiasis, including the prevalence of clinical signs associated with distichiasis, in a large population of dogs in France.…”

Objective To describe the epidemiological factors and clinical significance of canine distichiasis. Animals studied Two hundred and ninety‐one client‐owned dogs. Methods Retrospective study of medical records for canine patients diagnosed with distichiasis between 2010 and 2019 in an ophthalmology specialty practice. The breed, sex, skull conformation, coat type, age at the time of diagnosis, reason for presentation, clinical examination findings, and affected eyelid(s) were reviewed. Results The prevalence of distichiasis was 5.5% (95% confidence interval (CI): 4.9–6.1) in the population of dogs presented to an ophthalmology specialty practice. The breeds with the highest prevalence were English bulldogs (35.2%, 95% CI: 26.7–43.7) and American cocker spaniels (19.4%, 95% CI: 8.3–30.5). The prevalence was significantly higher in brachycephalic dogs (11.9%, 95% CI: 9.8–14.0) than in non‐brachycephalic dogs (4.6%, 95% CI: 4.0–5.3) and in short‐haired dogs (8.2%, 95% CI: 6.8–9.6) than in dogs with other coat types (5.3%, 95% CI: 4.5–6.1). Most dogs were affected bilaterally (63.6%, 95% CI: 58.0–69.1). Among dogs with clinical signs, 39.0% (95% CI: 26.5–51.4) exhibited corneal ulceration, including superficial ulcers (28.8%, 95% CI: 17.3–40.4) and deep stromal ulcers (10.2%, 95% CI: 2.5–17.8). Distichiasis was non‐irritating in 85.0% (95% CI: 80.6–89.4) of affected dogs. Conclusion This study reports the largest cohort of canine distichiasis to date. In a large proportion of dogs, distichiasis was a non‐irritating condition. However, brachycephalic breeds, especially English bulldogs, were the most frequently and severely affected.

ObjectiveThe objective of the study was to evaluate visual outcomes between medical treatment alone (MED) and Ahmed glaucoma valve implantation (AGVI) in Shiba dogs with primary angle closure glaucoma (PACG).ProceduresRecords of 65 Shiba dogs (104 eyes) with PACG were retrospectively reviewed. Vision was assessed qualitatively using both the menace response and maze testing. The significance of age, sex, intraocular pressure (IOP), and duration of clinical signs (≤72 h or >72 h) at first presentation (V1) was assessed. Eyes with vision at V1 were divided into groups according to subsequent treatment method (MED versus AGVI), and vision as a survival outcome was compared between group by the Kaplan–Meier method.ResultsAt V1, 65 eyes (62.5%) of 54 dogs had vision. There was no statistically significant difference in age or sex on the presence of vision at V1. Median IOP was higher in blind (52 mmHg) compared to sighted eyes (28 mmHg) (p < .001). Eyes presenting in ≤72 h of the onset of clinical signs were more likely to have vision (86.7%) compared to those presenting after 72 h (44.1%) (p < .001). By the Kaplan–Meier analysis, the cumulative visual retention rate was significantly higher with AGVI than with MED (69.2% vs. 7.7%; p < .01) at 12 months. The median time to visual loss was 39.9 months with AGVI vs. 1.7 months with MED.ConclusionsAGVI resulted in better visual outcomes than MED and should be considered in Shiba dogs with PACG that are visual at the time of presentation and suitable for surgery.
