Ophthalmic examination revealed lackluster corneas, axial corneal scarring and pigmentation with associated neovascularization, and absolute KCS in both eyes. Computed tomography scan and endoscopic evaluation of the upper airway and guttural pouches revealed no structural abnormalities to indicate neurogenic KCS. The stallion was diagnosed with immune\u2010mediated dacryoadenitis as all other causes of KCS were excluded. Parotid duct transposition (PDT) was performed in the right eye followed by PDT in the left eye 4 weeks later. The right PDT was functional 2 years post\u2010operatively with significant improvement in ocular comfort and reduced corneal fibrosis and neovascularization. The left PDT developed a salivary\u2010cutaneous fistula over the left masseter muscle post\u2010operatively due to avascular necrosis of the distal parotid duct (PD). Surgical reconstruction of the PDT using an expanded\u2010polytetrafluoroethylene (e\u2010PTFE) tube graft, an e\u2010PTFE tube graft to autogenous caudal auricular vein graft, and an autogenous saphenous vein graft were all unsuccessful. Tear production in the left eye improved at 1 year post\u2010surgery as a result of long term lacrostimulant therapy, and a permanent PD\u2010cutaneous fistula was performed on the left PD at the level of the ventral mandible. Bilateral PDT in the horse is effective in resolving clinical signs associated with KCS; however, morbidity associated with avascular necrosis of the transposed PD may be significant and can result in surgical failure.<\/jats:p>","DOI":"10.1111\/j.1463-5224.2012.01068.x","type":"journal-article","created":{"date-parts":[[2012,10,16]],"date-time":"2012-10-16T04:03:30Z","timestamp":1350360210000},"page":"303-311","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Bilateral
