Aqueocentesis is performed readily with minimal risk. The results were primarily useful in aiding a diagnosis of lymphoma in both dogs and cats.

DBD significantly reduces the superficial stromal HAZ in SCCEDs. A reduction of its thickness may be responsible for the healing rates reported with DBD.

Objective To describe the phenotype of canine macular corneal dystrophy (MCD) including the clinical presentation, multimodal ocular imaging, histopathology, and ultrastructural analysis in ten Labrador Retrievers. Procedure Multicentered data collection. Results Labrador Retrievers affected by MCD were presented between the age of 4.5 and 6 years of age with a history of cloudy eyes and/or visual impairment. Findings on ophthalmic examination included a diffuse haze of the corneal stroma and multiple, well‐demarcated, off‐white to yellow‐brown, punctate corneal opacities heterogeneous in size. Corneal vascularization developed in most dogs as the disease progressed. Disease progression was associated with increased density of the corneal haze as well as increased number and size of the focal opacities and dogs developed significant visual impairment. Spectral domain‐optical coherence tomography revealed multifocal hyper‐reflective regions within the stroma. In vivo confocal microscopy revealed marked alterations in reflectivity throughout the entire stroma. Normal keratocytes could not be identified in affected areas. Histopathology showed stromal collagen fibers separated by acidophilic granular material on hematoxylin and eosin stain. The material stained with periodic acid‐Schiff and colloidal iron stain but not with Masson trichrome stain, confirming the accumulation of glycosaminoglycans. On electron microscopic ultrastructural examination, keratocytes presented with vacuolated rough endoplasmic reticulum and multiple electron dense cytoplasmic inclusions. In areas keratocytes appeared ruptured, with cell organelles and proteinaceous material grouped together between collagen fibers. Conclusion MCD in Labrador Retrievers has similarities with the human counterpart of the condition and is an important differential diagnosis in dogs with corneal disease.

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.
