Kim H-W, Yoon T-W, Kim J-Y. Preliminary clinical evaluation of the treatment efficacy of a temperature-adjustable cryotherapy device for chronic, recurrent blepharitis in dogs. Vet Ophthalmol. 2024;27(6):583-589. doi:10.1111/vop.13305
Research Note
Blepharitis and periocular inflammation in dogs can have various causes, but allergies are the most common etiology.1 Treatment typically includes administration of topical and/or systemic corticosteroids, as well as addressing the underlying cause. In human atopic patients, cryotherapy has been found to decrease pruritus.2
This study evaluated whether a temperature-adjustable cryotherapy device could improve clinical signs in dogs with refractory blepharitis. Cryotherapy was performed once weekly for 3 to 6 weeks in 5 dogs (8 eyes) with blepharitis unresponsive to systemic corticosteroids. Topical antibiotics and corticosteroids were administered twice daily for the duration of treatment. Pruritus improved in all eyes; however, erythema and swelling only improved in 3 eyes. Tear film quality improved in 7 eyes. The authors concluded that cryotherapy may be helpful for treating blepharitis with pruritus, but larger-scale studies are needed.
