ABSTRACT
OBJECTIVE:
To examine the prevalence of nasolacrimal duct (NLD) obstruction in hospital populations and assess signalment, diagnostics, and clinical approaches for alpacas and llamas diagnosed with NLD atresia or obstruction. ANIMALS 29 alpacas and 2 llamas. CLINICAL PRESENTATION Medical records were reviewed to identify camelids with NLD evaluated between 2000 and 2023. Signalment, history, physical examination data, diagnosis, and treatments were recorded. Follow-up information was gathered via phone and email questionnaire. Data were evaluated to determine prevalence and describe signalment and treatments for NLD disease.RESULTS:
31 camelids met the inclusion criteria. A total of 8,027 alpacas and 1,998 llamas were seen within the study period at 1 teaching institution. The prevalence of NLD obstruction for this population of alpacas was 0.3% (26/8,027). Nineteen of 31 (61%) camelids presented at 1 year of age or younger. The most common physical exam finding was ocular discharge (68%). The most common diagnosis was NLD atresia (16/31 [51%]). Patency was established by surgical opening or lavage of the NLD. Long-term follow-up was available for 13 alpacas and 2 llamas, of which 11 (73%) had successful outcomes. CLINICAL RELEVANCE Results indicate that NLD obstruction is a condition that most commonly affects alpacas < 1 year of age and is associated with a good prognosis for treatment success.Key words
