Lasers are routinely used in veterinary ophthalmology for the treatment of a number of ophthalmic conditions and diseases. In veterinary ophthalmology, gas lasers (CO 2 lasers) and semiconductor lasers (diode lasers) are used primarily, but the therapy of posterior capsular opacification with the Nd:YAG laser has also been described. This paper presents and discusses the most common indications for the use of the diode and CO 2 lasers. Diode lasers are mainly used in the treatment of glaucoma, either by transscleral cyclophotocoagulation or by endoscopic cyclophotocoagulation. Other indications are various forms of retinal detachments, as well as pigmented neoplasms of the uvea. An emerging field in veterinary ophthalmology using diode lasers is photodynamic therapy of periocular tumors. CO 2 lasers are used for pars plana vitrectomies and surgical excision of ocular tumors.
