Lower lid entropion in dogs: A modified technique of the combined Hotz-Celsus and wedge resection procedure.

BACKGROUND: This study aimed to describe a modification of the combined Hotz-Celsus and wedge resection technique for the treatment of lower lid entropion in dogs and evaluate its success rate. METHODS: To reduce tissue trauma, facilitate tissue handling and shorten the surgical time, shortening of the eyelid was performed by excising a rectangular piece of the eyelid margin only, in the central section, extending to but not below the first Hotz-Celsus incision. The eyelid margin surgical wound was then sutured before excision of the Hotz-Celsus crescent which had been surgically scored at the start of surgery. Records of 31 dogs were reviewed for signalment, outcome, need for further surgery, and follow up from 6 to 48 months after surgery. RESULTS: Sixty-one eyes with lower lid entropion were treated. The most common breeds were English bulldog and English cocker spaniel and the median age was 16 months. The success rate for a single entropion correction surgery was 98.4%. One eyelid required a second surgical correction and four eyelids of three large breed dogs had wound breakdown. CONCLUSIONS: This modified technique is successful at correcting lower eyelid entropion associated with overlong eyelid length in dogs while being technically easier to perform.

Uveal cysts in domestic cats: a retrospective evaluation of thirty-six cases.

OBJECTIVE: The aim of this retrospective study was to investigate uveal cysts in domestic cats by identifying prevalence, predispositions, location, presumed etiologies, and sequelae. ANIMALS STUDIED: The clinical databases of two referral hospitals (The Animal Health Trust in the UK and Animal Eye Care in Australia) were searched to identify cats that had been diagnosed with uveal cysts, either as an incidental finding or as the reason for referral. Thirty-six cases were found. PROCEDURES: The signalment of the patients was recorded, along with any relevant previous clinical history, treatment, follow-up, and sequela. The data were compared with the unaffected feline populations examined by ophthalmologists in the two hospitals over the same 10-year time period. RESULTS: Thirty-six cats were affected, from a total examined population of 5017 (prevalence 0.72%). Twenty-one of the 36 cats were Burmese. The two centers examined 516 Burmese cats in the same time period, giving an incidence in Burmese cats of 4.1%. The mean age of affected cats at presentation was 10.25 years (SD = 4.12 years), and female cats accounted for 23 of 36 of the cases. Only 2 of 36 cats had concurrent intraocular disease. CONCLUSIONS: Uveal cysts in domestic cats are rare ophthalmic findings, and in most cases, they do not cause any clinical problems The Burmese breed is overrepresented in the data, with a relatively high prevalence of uveal cysts.

Surgical management and outcome of lower eyelid entropion in 124 cats.

OBJECTIVES: To evaluate the success rate of various surgical techniques for the management of lower eyelid entropion in cats. DESIGN: Retrospective study. Animals studied One hundred and twenty-four cats with surgical correction of lower eyelid entropion of 200 eyes over a 13 year period. METHODS: Records of 124 cats were reviewed for signalment, type of entropion, surgical procedure performed and post-operative result. RESULTS: Combinations of the Hotz-Celsus (HC), lateral canthal closure and full thickness wedge resection techniques were used to treat 64 bilateral and 60 unilateral cases of lower lid entropion. Twenty-three cats were under a year of age, 52 cats were aged between 2 and 8 years and 49 were over 8 years old. The overall success rate for a single surgical procedure (which may consist of multiple techniques) to correct lower eyelid entropion was 96.0% per eye. The remaining 4.0% had the entropion resolved with a second surgery. A combined HC and lateral canthal closure had a 99.21% success rate of resolving lower lid entropion. Geriatric cats were the most likely age group to develop corneal sequestra; 37% of cats in this group presented with entropion and corneal sequestra concurrently. Seventeen percent of cats that presented with unilateral entropion and did not have prophylactic surgery on the fellow eye went on to develop entropion in the fellow eye. CONCLUSIONS: A combined HC and lateral canthal closure was the most effective surgical technique in managing lower eyelid entropion of cats in our study. Prophylactic lateral canthal closure in the unaffected eye is recommended.
