[Immediately sequential bilateral cataract surgery in dogs: a retrospective analysis of 128 cases (256 eyes)]. / Chirurgie de la cataracte bilatérale immédiatement séquentielle chez le chien : une étude rétrospective de 128 cas (256 yeux).

OBJECTIVE: To describe postoperative complications and visual outcomes after immediately sequential bilateral cataract surgery (ISBCS) and to assess whether additional risk is incurred by operating on the fellow eye immediately following the first. ANIMALS STUDIED: A retrospective review of 128 dogs (256 eyes) that underwent ISBCS in three veterinary ophthalmology centers between May 2007 and December 2011 was performed. PROCEDURE: Visual status at final evaluation was recorded and intra- and postoperative complications were recorded and analyzed. Data for the first operated eye (FE) and then the second eye (SE) were statistically analyzed to assess whether performing surgery on the SE immediately after the FE resulted in any negative consequences for the second eye. RESULTS: No serious intraoperative anesthetic incident occurred due to prolonged surgery. Phacoemulsification times were significantly shorter for the SE than for the FE. On final examination, 239 eyes out of 256 (93.36%) exhibited functional vision (score 2), and three dogs were completely blind due to long-term bilateral postoperative complications. The most common postoperative complications were uveitis (58 eyes, 22.66%), postoperative ocular hypertension (POH; nine eyes, 3.5%), glaucoma (nine eyes, 3.5%) and total retinal detachment (seven eyes, 2.73%). No case of endophthalmitis was reported. These results were no worse than those typically reported for unilateral phacoemulsification. In addition, the risk of blindness and other postoperative complications was not significantly increased in the SE. CONCLUSIONS: The results of this study suggest that ISBCS is not associated with an increased incidence of intra- or postoperative complications compared to classic unilateral cataract surgery and might be a viable option for selected patients. The risk of blindness or postoperative complications was not higher in SEs than in FEs.

[Extraocular myositis and comparative pathology: two case reports in the dog]. / Myosite des muscles extraoculaires et pathologie comparée : à propos de deux cas chez le chien.

Two cases of extraocular myositis in dogs are reported in a golden retriever and an Australian shepherd. This condition is characterized by sudden bilateral exophthalmos, the absence of pain and third eyelid protrusion, orbital sonography showing the enlargement of extraocular muscles, and a quick response to systemic steroids at an anti-inflammatory dose. The literature review reports a breed predisposition in the golden retriever, mainly in females. Histopathologic evaluations confirm the inflammation of one or several extraocular muscles. Chronic disease was also described. Canine extraocular myositis shows some resemblance to Graves ophthalmopathy but can better be compared to idiopathic orbital myositis. Both disorders are probably the consequence of an immune dysfunction that still has to be discovered.
