The objective of this study was to evaluate the effectiveness of two protocols of treatment of keratoconjunctivitis sicca (CCS) experimentally induced in rabbits, a topical ophthalmic formulation consisting of 1.4% alcohol povinílico, added with acetylcysteine 10% and 1% pilocarpine (AAP) and another protocol with the use of flaxseed oil (OL) topic in the form of eye drops. A total of 15 white rabbits, male New Zeland. These animals were divided into three groups with five animals each: Group C (control), healthy animals; Group AAP (formula for topical ophthalmic) and Group L (flaxseed oil topically). The rabbits were evaluated weekly by the Schirmer test Lacrimal (TLS), Rose Bengal test (TRB) and Fluorescein test (TF). Monthly tests were performed cytology (EC) and the end of the experiment was carried out euthanasia of animals for histopathological examination of the eyes. There was significant clinical improvement in the parameters analyzed (TLS, TRB and TF) in both groups (AAP, L). However, the AAP group, showed a better effect on the production of tears from the moment 2 (M2), when compared to L. Both groups had values higher than in Group C, and remained superior to the M12. The group L, showed a better effect for the presence of corneal ulcers, which remained negative at all times, while the AAP group was positive from the M3 to M9. Regarding the presence of devitalized cells, the group L showed a better performance, and 100% of their animals from the negative to the M7, while the AAP group animals showed negative for devitalized cells from the M10. In cytology was not observed significant differences between groups. In histopathology of the cornea and conjunctiva, there was edema and degeneration in both groups, but necrosis was observed only in the conjunctiva in the group L. There was a significant increase in goblet cells, especially in the AAP group. Considering the results analyzed, both the formula ophthalmic and flaxseed oil are effective in the treatment of CCS, however, the ophthalmic formulation is more effective to increase the tear, while linseed oil was more effective in resolving ulcers corneal cells and devitalized.
