OBJECTIVE: To evaluate the effect of topical ophthalmic 0.005% latanoprost alone and in combination with 0.1% diclofenac on healthy horses.
ANIMALS STUDIED: Twelve healthy adult horses.
PROCEDURES: A randomized, masked crossover design was used with horses divided into three groups for once daily treatment in one randomly selected eye. For arm 1 of the study, Group D (n = 3) received 0.1% diclofenac, Group L (n = 3) received 0.005% latanoprost, and Group DL (n = 6) received 0.005% latanoprost and 0.2 ml of 0.1% diclofenac. For arm 2 of the study, horses from Group D and L were placed into Group DL and horses from Group DL were placed into either Group D or L. Evaluations of intraocular pressure (IOP), vertical pupil diameter, aqueous flare, conjunctival hyperemia, epiphora, blepharospasm, and blepharoedema were performed 4 times daily on days 1 and 2 (baseline), days 3 to 7 (arm 1 treatment), days 8 to 11 (washout), days 12 to 16 (arm 2 treatment), and days 17 and 18 (return to baseline).
RESULTS: During the treatment period, significant reduction in IOP and vertical pupil diameter occurred in treated eyes of Groups L and DL, but not Group D. These variables did not differ significantly between Groups L and DL. Blepharospasm, blepharoedema, epiphora, and conjunctival hyperemia scores were significantly higher in Group L than in Groups D and DL.
CONCLUSIONS: Latanoprost reduced IOP in healthy horses and signs of drug-induced discomfort were mitigated by concurrent use of diclofenac.
