Abstract
PURPOSE
To evaluate the clinical outcome, possible complications, and recurrence rate of distichiasis in dogs treated with partial tarsal plate excision (PTPE) technique using a transconjunctival approach.
METHODS
Retrospective study including 17 client-owned canine patients affected with distichiasis and presenting with associated clinical signs (ie, blepharospasm, epiphora, chronic keratoconjunctivitis, or corneal ulceration) that underwent surgical removal of the aberrant lashes using a PTPE technique between January 2018 and February 2019. Data collected included breed, age, sex, affected eyelid(s), number of distichia, and tear film breakup time (TBUT). Resected cilia-bearing tarsoconjunctival strips were submitted for histopathological analysis.
RESULTS
Thirty eyes (52 eyelids) from 17 dogs were included in the study. The median age was 688 days (range 118-4243 days). A successful outcome, defined as complete resolution of clinical signs attributable to the distichia, occurred in all eyes after a single procedure, with a mean follow-up time of 239 days (range 69-480 days). Appearance of new distichia occurred in 14/30 eyes (46.3%), and of these, three eyes needed a new PTPE procedure. Recurrence of the distichia only occurred in one eye (3.3%) which was asymptomatic. Following surgery, TBUT decreased below the normal value in 7/24 eyes (29.1%) although none developed clinical signs of qualitative tear film deficiency. Post-operative complications included trichiasis and cicatricial entropion, which developed in two eyes (6.6%), and these were successfully managed with corrective eyelid surgery.
CONCLUSIONS
Partial tarsal plate excision, using a transconjunctival approach, had an excellent clinical outcome with a low incidence of complications.
