A Cross-sectional Online Questionnaire-based Survey About the Use of Compounded Medications in Veterinary Ophthalmology.

The aims of this survey were to determine how veterinary ophthalmologists worldwide use compounded ophthalmic drugs to treat ocular diseases, define their attitudes regarding compounding pharmacies, and identify commonly dispensed veterinary ophthalmic formulations as well as the diseases for which those preparations are most often prescribed. Respondents voluntar i ly and anonymously completed a questionnaire that was sent to a total of 1014 veterinary ophthalmologists at universities, specialty colleges, and ophthalmology associations in 24 countries. One hundred thirty (12.83%) veterinary ophthalmologists replied. Of those, 87 (66.92%) had worked in  veterinary ophthalmology for more than 10 years. Ten to 30% of their total prescriptions were compounded ophthalmic drugs, the most common of which were tacrolimus and cyclosporine for the treatment of keratoconjunctivitis sicca. Reported advantages of treatment with a compound included the accessibility of preparations that were not commercially available and the ability to customize formulations; reported disadvantages included brief shelf life, delivery time, and cost.
