Purpose To describe the outcome of modified brow suspension technique for the treatment of upper eyelid pseudoptosis in canine patients with redundant frontal skin folds.Methods Medical records from 1999 to 2015 were retrospectively reviewed. Only dogs that underwent modified brow suspension for treating bilateral pseudoptosis were included in the study. Recorded data included breed, age, gender, main ophthalmic complaint, ocular findings, suture material used for brow suspension, number of slingsplaced, post operative treatment, complications, follow-up time, and outcome.Results Twenty-five adult dogs of different gender and breed fulfilled the inclusion criteria, with the Shar-Pei being overrepresented (19/25;76%). The main complaint atfirst presentation was mucopurulent discharge (10/25;40%) and blepharospasm (10/25;40%). Concurrent corneal disease was diagnosed in 47 eyes (47/50;94%). Monofila-ment polyamide was the most frequently used suture material (46/50;92%). Number of slings placed varied, with one in two eyes (4%), two in 28 eyes (56%), three in 17eyes (34%), and four in three eyes (6%). Complications were seen in three eyes (6%):suture rupture (one eye; 2%) and skin abscess (two eyes; 4%). Mean follow-up timewas 17.6 months (1–84 months), with no cases of fold dermatitis or dermatologic disease observed within this period. Good esthetic and functional outcomes were obtained in 47 eyes at first intervention (97%) and in all patients after re-intervention.Conclusions The modified brow suspension technique described offers a surgical alternative for dogs with pseudoptosis secondary to redundant frontal skin folds that potentially reduces anesthetic time and facial changes.
