Abstract
In the present study entitled "Ophthalmic affections in canines: incidence, therapeutic and surgical management" a retrospective analysis of the ophthalmic records at the Department of Surgery from 2004-2009 was done to find out the incidence, distribution and pattern of ocular affections. The study also evaluated the therapeutical and surgical management of various ocular affections reported from August 2007 - March 2009. A total of 443 canine ocular cases were reported during 2004 - 2009, which constituted 13.80% of total surgical case load (3210).The incidence was more during summer months with more number of cases in dogs between 5-10 years. Breed wise incidence was maximum in spitz (60.73%) followed by german shepherds (11.06%). Sex wise incidence was more in males (60%). Anatomical categorization of the ocular affections revealed maximum cases involving lens followed by that of cornea, eyelid, retina, conjunctiva, glaucoma, anterior chamber and globe. The standard medical management for conditions like conjunctivitis, superficial corneal ulcers, hyphema, hypopion, glaucoma was effective. Treatment of prolapsed third eyelid gland by its removal following linear incision over the bulbar conjunctiva was found superior to blunt excision in terms of reduced postoperative incidence of keratoconjunctivitis sicca. Extracapsular cataract extraction (ECCE) along with implantation of 41 diopteric intraocular lenses with 6.5 mm optic and 17 mm haptic using operating microscope restored vision in 64% cases. The most common intraoperative complications during ECCE were bleeding from iris, pupillary constriction, iris and vitreal prolapse and chemosis. Corneal opacity, corneal oedema, posterior capsular opacity and displacement of the implanted lOL were the major postoperative complications after ECCE. Twenty two cases of progressive retinal atrophy with maximum cases (19) in spitz and four cases of retinal detachment were diagnosed by indirect ophthalmoscopy.
