Resumo
The third eyelid is a thin layer composed by conjunctive tissue, T shaped hyaline cartilage and a gland that
contributes in dog’s tears production. The most common condition of the third eyelid is gland prolapse, with indication
of surgical correction. Seven dogs, male and female, 10.2 ± 1.6 kg, mixed breed, without ocular alterations, had their tear
production evaluated by Schimer’s lacrimal test, 24 hours before unilateral exerese of the right third eyelid’s gland, and 15, 30 and 60 days after the operation. An incision was made in the conjunctive eyelid layer, around the gland, to
liberate and remove it. The animals were treated with topic ophthalmic cream, containing 0.1% dexametason, 0.35%
neomycin and B type polymyxin 6000 UI every 12 hours, during 7 days post-operation. Friedman’s x2 test, with 5% of
significance level, showed that there was no significant differences in tear production between post-operatory
(21.7143mm/min) and 60 days post operation (21.2857mm/min). Unilateral exerese of the third eyelid’s gland in dogs did
not interfere in tear production, and don’t showed clinical change in the cornea and conjunctive tissues, during 60
days of evaluation.
