| Ophthalmic lesions induced by contact with Sodium hydroxide (NaOH) at 3 M concentration in 42 dogs, divided into three groups (G1, G2 and G3), respectively treated with autogenous blood serum, acetylcysteine and a balanced saline solution were investigated. Comparison of the three groups in terms of clinical and microscopical findings showed no significant differences between groups. |

| The effects of sildenafil on retrobulbar and retinal circulation were studied in 18 adult male, albino, homozygous rabbits, of the New Zealand White breed, randomly divided into 3 groups of 6 animals, for drug treatment at a dose of 3.5mg kg-1 every 24 hours, for 7, 15 and 30 days. Nine animals used for control were treated with saline solution at 0.9%. It was evaluated intraocular pressure (IOP), mean arterial pressure (MAP), ocular perfusion pressure (PPO), B-mode ultrasonography and fluorescein angiography before and at the end of treatments. A slight decrease in results of IOP, MAP and PPO after treatment with sildenafil was evident, however, there was no statistical significance. It was observed significant increased diameter of the ophthalmic artery... |

| Myoplasties of the extraocular muscle may cause adhesions between the operated muscle and the adjacent tissues, commonly generating cicatricial strabismus. With the purpose of reducing to a minimum the occurrence of adhesion, the effects of mitomycin C, an antifibrotic agent, were studied in concentrations of 0.008%, 0.02%, and 0.04% applied during intraoperative of myoplasties of the superior rectus muscle of rabbits. Fifty six animals were divided in five groups. During the postoperative, the operated areas were washed with physiological solution. Eye drop instillation to prevent inflammation and bacterial infection were used. The method to analyze the results consisted of clinical and histological evaluation and statistical analyzes. We also evaluated... |

| The objective of this research was to present an experimental model for the prolapse of the third eyelid gland in male, adult mongrel dogs by the use of a periorbital glandular support conjunctiva tissue resection followed by macro and microscopic assessments. Length, thickness and width of normal glands were statistically studied at baseline and then again after a period of 30 days of exposition. In relation to the experimental model, 84.21% of glands, which underwent the resection of the conjunctiva support tissue, support tissue, remained protusioned. There were significant differences between normal and protusioned glands. Protusioned glands were larger in respect to length, thickness and width. For the microscopy studies, two experimental groups were... |

| ABSTRACT: The objective of this research was to evaluate the clinical and microscopic effects in rabbits of lamellar keratoplasty using allogeneic omentum associated with canine amniotic membrane (AM). Rabbits were divided into two groups: one received the allogeneic free omental graft covered with the AM (OM-graft group), while the other received the AM graft containing omental mesenchymal cells (OM-cell group). Clinical signs were evaluated on different postoperative days. After the clinical assessments, the rabbits were euthanized and their corneas were obtained for histopathology and immunohistochemistry (Ki-67, marker for proliferation). Both groups showed chemosis, blepharospasm, eye discharge, hyperemia, and corneal opacity/edema. Neovascularization... |

| The lacrimal and third eyelid superficial glands produce the aqueous component of the preocular tear film. In this research, morphologic and morphometric assessments of the parenchyma and stroma of both lacrimal glands of healthy adult mongrel dogs were performed. Both lacrimal and third eyelid glands of fourteen dogs were collected, summing fifty-six samples. The macroscopic and morphometric data were statistically analyzed, according to the glandular type (lacrimal and third eyelid superficial glands) and sexual dimorphism (male or female). The lacrimal glands were significantly larger and longer than the superficial glands of the third eyelid. Expressive morphometric differences of interlobular duct, lymphocytic infiltration, interlobular vessels and... |

| Cataract is one of the most common ocular diseases in dogs, and phacoemulsification is considered its treatment of choice. Posterior capsular opacity (PCO) is a frequent complication and may occur weeks or months after the surgery. It is known that intraocular lenses (IOL) used for the correction of post-operative hypermetropia are an adjunctive aid in the prevention of PCOs, mainly the foldable acrylics designs with square and truncated edges. However, IOL placement may result in endothelial cell loss. This study evaluated the morphology and cellularity of the endothelium by non-contact specular microscopy in aphakic and pseudophakic dogs. Endothelial cell density, endothelial cell area, coefficient of variation and hexagonal cells percent were analyzed... |

| Trichiasis is a condition in which lhe cuia and facial hairs grow toward lhe córnea or the conjunctiva. The hairs arising from normal sites are pointed aí an abnormal direction. This condition may be caused by prominent nasal folds, entropion, blepharospasm, slipped facial mask and dermoids. The upper eyelid trichiasis-entropion with lower eyelid entropionectropion frequentiy occurs in oíder English Cocker Spaniels. The ocular signs often are epiphora, blepharospasm, conjunctivitis, keratitis and comeal ulceratíon. Treatment depenas on the severity ofthe condition and must eliminate the ocular contact by misdirected cuia that irritate the eyeball. This report presents a retrospective study of21 patients with bilateral diffüse trichiasis (15 English Cocker... |

| Tear film disorders in dogs can be classified into quantitative or qualitative abnormalities, or both, and are commonly observed in daily clinical practice. Inadequate production of one or more tear film components can lead to variable degrees of ocular disorders, called keratoconjunctivitis sicca. Keratoconjunctivitis sicca in dogs has several causes, but in most cases the disease is idiopathic, with T lymphocytes playing a role. In veterinary medicine, the diagnosis is made based on the results of the Schirmer tear test. In this article, we review aspects related to the etiopathogenesis and diagnosis of keratoconjunctivitis sicca in dogs and discuss new therapeutic modalities for this disease. |

| Corneal endothelium constitutes a monolayer of polygonal cells. The integrity and health of this layer are essential for the maintenance of normal corneal transparency. This study reported by the first time in a detailed way the ultrastructural morphology and morphometry of the corneal endothelium in normal adult crossbred pigs by using scanning electron microscopy (SEM). A regular pattern of polygonal cells, with predominantly hexagonal cells and clear cell borders, was observed. An oval nucleus that bulges in the centre of the cell, cilia (2-4) in a few peripheral cells, openings of the pinocytotic vesicles, microvilli, borders bars and interdigitated cell borders were observed. The mean endothelial cell area was significantly higher (P<0.05) in the... |

| ABSTRACT: This study examined the efficacy of an intravitreal dexamethasone-loaded device for the control of postoperative ocular inflammation in dogs following phacoemulsification. Twenty dogs with bilateral mature senile cataracts were prepared for surgery using routine protocols. A biodegradable poly (lactic-co-glycolic acid) copolymer device was inserted through the pars plana into the vitreous chamber immediately before phacoemulsification (device group [DG], n=20). Following surgery, a conventional group (CG) received local and systemic steroids, mydriatics, and antibiotic therapy. The same treatment protocol was adopted in DG, except for steroids. All eyes were examined before surgery and at various times after phacoemulsification. Ultrasonography... |
