| Leishmaniose é uma enfermidade multissistêmica cujas manifestações clínicas são extremamente variáveis. Em cães sinais clínicos oftálmicos são relativamente frequentes, ainda que outros sinais sistêmicos não sejam identificados. Atualmente, o diagnóstico da doença baseia-se em métodos parasitológicos, sorológicos e moleculares, mas, até o momento, a identificação de formas amastigotas desse parasito em esfregaços feitos a partir de suabes conjuntivais não é empregada rotineiramente. Valendo-se de cães sorologicamente positivos para leishmaniose, portadores (G1) ou não (G2) de alterações oftálmicas, este estudo avaliou a viabilidade do esfregaço a partir de suabe conjuntival como método de diagnóstico para a enfermidade. O exame suprarreferido foi positivo... |

| Sildenafil citrate is a type-5 phosphodiesterase inhibitor (PDE-5), able to inhibit type-6 phosphodiesterase (PDE-6) as well, providing clinical benefits and paraeffects, some of them potentially related to the retina. The effects of the sildenafil on the retrobulbar and retinal circulation were studied in 27 adult male rabbits of the White New Zealand breed. The electric activity of the retina was evaluated before and at the end of the treatments, and immunohistochemistry studies were conducted. An amplitude increase of the b wave was found in the mixed response of cones and rods after 7 days of treatment with sildenafil citrate. However, in the other evaluations and periods, the values did not differ from the basal ones. Through immunohistochemistry, no... |

| ABSTRACT Eyes from brachycephalic dogs were studied by acoustic radiation force impulse (ARFI) elastography to establish quantitative and qualitative reference values related to the shape and rigidity of some ocular structures. Eighty-four eyes from 42 adult brachycephalic dogs were included in this study. Animals were subjected to physical, laboratory, and ophthalmic examinations. Following confirmation of good health, the dogs were subjected to ultrasonography and ARFI elastography, emphasizing the optic nerve, ciliary body, and lens. On qualitative elastography, homogeneous characteristics were observed on the ciliary body and optic nerve. Aqueous and vitreous humors were visualized as mosaic-like images. Quantitative elastography showed the mean optic... |

| It was reported a case of a 9-year-old Brazilian Fila male dog that had been affected by a tissular formation of the nictitant membrane of the right eye with four months of evolution. Conjunctival hyperemia and edema, serosanguinolent secretion, and a conjunctival neoformation at the nictitant membrane were observed. Surgical exeresis of the neoformation was performed. Endothelial cells slightly differentiated and pleomorphic, with an intense vascular neoformation compatible to nictitant membrane hemangiosarcoma, were found at the histological exam. |

| The evaluation of lens by ultrasonography, previously to phacoemulsification, can offer relevant information, markedly such as aspects and dimensions, allowing design safer surgical strategies with enhanced outcomes. Within the contents of this research, the biometry was performed in lens of dogs with senile immature, mature, and diabetic cataracts, previously to phacoemulsification, using mode A and mode B ultrasonography, simultaneously. The values obtained for axial diameter of the eyes, anterior chamber, lens, and vitreous chamber were, respectively, 19.22mm, 2.35mm, 7.94mm, and 8.94mm. Diabetic cataractous lens were larger (8.90mm), compared to mature cataract (8.12mm). Lens with immature cataract were smaller in dimension than those with mature and... |

| The use of ethyl-cyanoacrylate and octyl-cyanoacrylate were clinically and histopathologically compared on the corneas of 36 rabbits after lamellar keratectomy (standardized diameter and depth). The animals were distributed into two groups, one for each type of adhesive. From each group, six subgroups were histopathologically evaluated on the 3rd, 7th, 14th, 21st, 30th, and 60th day post-operative. General (daily) and ophthalmic (days 0, 1, 3, 5, 7, 14, 21, 30, 44, and 60) evaluations clinically indicated that there were significant differences for the variables water intake, attitude, blepharitis, corneal edema, and fluorescein test. The adhesive permanence time for octyl-cyanoacrylate (17.22 days) was greater than that for ethyl-cyanoacrylate (7.66... |

| The effects of sclerocorneal limbal stem cell autograft transplantation in dogs with corneal wounds were studied. Eighteen dogs were divided in two groups (GI and GII). The animals of GI (n=12) underwent limbal transplantation 30 days after the destruction of limbal stem cells. The dogs of GII (n=6) only underwent destruction of stem cells (control group). Light microscopy examination of the right eye was performed on days 3, 7, 14, 30, 60, and 120 after limbal transplantation (GI), and on days 33, 37, 44, 60, 90, and 150 after limbal destruction (GII). Results showed a complete destruction of limbal stem cells with loss of corneal transparency. Limbal transplantation prevented conjunctivalization in grafted area. Corneal vascularization and a 360º corneal... |

| Efficacy of carprofen, administered by different routes, was studied in experimental uveitis in dogs. Anterior chamber paracenteses was accomplished at two different moments (M0 and M1), with a five hour interval between them. At M0 and M1, 0.2mL of aqueous humor was collected and quantitation of total protein and prostaglandin E2 (PGE2) were determined. Four groups were formed (n=8), which received carprofen at the end of M0, by the following routes: subcutaneous (GIm), subconjunctival (GII), and topical (GIII). A fourth group that received no treatment was instituted (Control). Conjunctival histopathology of the GII animals was performed. In all groups, values of protein and PGE2 significantly enhanced at M1; however, they did not significantly change... |

| It was studied the nuclear fragmentation technique for lens extraction in six adult horses using adapted surgical instruments. Postoperative assessment revealed a reduction of intraocular pressure in all animals during the first postoperative days, as well as varying degrees of photophobia, blepharospasm, corneal edema, and iridocyclitis. Fibrin formation mainly located in the axial portion of the pupilla was noted in most cases, affecting or impairing vision. |
