Introduction: Recurrence after surgical replacement of the third eyelid gland occurs in 5-10% of cases. Re-operation is not always possible and in re-operated cases success is not evident.

Objective: Evaluate clinical effects of auto transplantation of part of the third eyelid lacrimal gland to the conjunctival fornix as an alternative for ocular aqueous lubrication in situations of recurrence after surgical pocket technique replacement.


Methods: Eight dogs   were selected. Schirmer Tear Test (STT) was performed to estimate the quantity of tears. Patients were submitted to a complete ophthalmic exam preoperatively and postoperatively for three months. STT was done for post-operative evaluation. Surgical procedure consisted in: excise the recurred prolapsed gland, graft removal from halfway of the gland in a elliptical shape 10 mm width with a 11 blade, construction of a conjunctival superior temporal fornix pocket and suturing in an isolated pattern with 6-0 polyglactin.


Results:  Conjunctival hyperemia disappears in 98% of cases and corneal neovascularization and blepharospasm in all cases (100%); corneal luster was restored after surgery in 98,55% of cases; 
in all animals an increase (plus 56.25%) in STT was observed (pretest  +/-SD 6.125 +/-3.14 to 14.0 +/-3.85); all data were statistically significant (p < 0,05). Conclusion: All patients in this study showed improvement and the technique is easy to perform and seems to be an alternative approach in cases of recurrence afetr surgical replacement.
