| O cavalo, dado o seu meio ambiente, está sujeito a afecções frequentes da córnea e da conjuntiva, tecidos oculares bastante expostos a bactérias e fungos, principalmente Aspergillus spp. e Fusarium spp. As ceratites ulcerativas bacterianas e fúngicas, bem como as ceratites fúngicas não ulcerativas, caracterizadas principalmente pelo abscesso estromal, são frequentes nessa espécie. Ocorrida a lesão inicial, perpetua-se um ciclo vicioso, com liberação de citocinas inflamatórias, que desencadeiam uma rápida e severa infiltração corneal por células polimorfonucleares. A córnea torna-se sujeita à destruição por enzimas proteolíticas liberadas pelos micro-organismos e por células inflamatórias, capazes de desencadear a dissolução estromal e a perfuração do bulbo... |

| 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... |

| 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. |

| 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... |
