A oftalmologia veterinária abrange o diagnóstico das alterações oculares, perioculares e retrobulbares primárias, e também suas manifestações sistêmicas e secundárias, o que se torna possível a partir da avaliação completa do bulbo ocular, órbita e anexos por meio do exame oftálmico completo e de exames complementares. Dentre os exames de imagens que auxiliam no diagnóstico das afecções oculares, a ultrassonografia está entre os exames de imagem mais utilizados na rotina veterinária, auxiliando na observação de anormalidades retrobulbares e na avaliação das estruturas bulbares na presença de opacificação de meios transparentes, por exemplo. Além da ultrassonografia, existem outras modalidades de exames, dentre eles a tomografia computadorizada, ressonância magnética, angiografia, microscopia especular, tomografia de coerência óptica (OCT) e angiografia por tomografia de coerência óptica (OCT-A). Em virtude dos avanços tecnológicos na obtenção de imagens, a avaliação globo ocular e das estruturas orbitárias pode ser realizada com maior precisão, o que favorece o diagnóstico e a escolha terapêutica adequada. Objetiva-se com esta revisão enumerar os exames disponíveis, suas principais indicações, bem como sua aplicabilidade e estudos em animais domésticos.

The presence of trichobezoar in cats is characterized by the accumulation of hair in the gastric cavity, which may be associated with the presence of dermatitis caused by the presence of the mite Lynxacarus radovskyi. In the present report, a clinical case of a feline patient with diagnostic and surgical diagnosis of the presence of a trichobezoar with the presence of Lynxacarus radovskyi in a skin scrape examination was described.

OBJECTIVE To describe selected ophthalmic tests and anatomical features of eyes of crab-eating foxes (Cerdocyon thous) and maned wolves (Chrysocyon brachyurus). ANIMALS STUDIED Six crab-eating foxes (12 eyes), eight maned wolves (16 eyes). PROCEDURES Intramuscular and/or inhalatory anesthesia, ophthalmic evaluation with portable slit-lamp biomicroscope, Schirmer tear test (STT), intraocular pressure measurement with rebound and applanation (crab-eating fox only) tonometers, measurement of palpebral fissure length (PFL), gonioscopy, and fundoscopy. Data were analyzed with ANOVA and Tukey's tests. RESULTS Both species presented upper and lower eyelids, both with eyelashes and Meibomian glands openings. A third eyelid was also present. In partial miosis, pigmented projections were observed along the edge of the pupil. The draining angle was open, with thin pectinate ligaments. The retina was holangiotic. For crab-eating foxes, mean ± standard deviation values were as follows: STT: 4.33 ± 2.96 mm/min; PFL: 17.45 ± 1.55 mm; rebound tonometry: 10.70 ± 3.43 mm Hg (TonoVet® calibration D),5.66 ± 3.44 mm Hg (TonoVet® calibration P), 17.00 ± 4.64 mm Hg (TonoVet® Plus calibration dog); and applanation tonometry: 11.70 ± 5.70 mm Hg(TonoPen® XL). For maned wolves, the mean ± standard deviation values were as follows: STT: 9.31 ± 7.40 mm/min; PFL: 22.79 ± 1.63 mm; rebound tonometry: 11.00 ± 2.77 mm Hg (TonoVet® calibration D), 6.78 ± 2.58 mm Hg (TonoVet® calibration P), and 18.29 ± 3.47 mm Hg(TonoVet® Plus calibration dog). CONCLUSIONS This study contributes with knowledge that can help the clinical assessment regarding eyes of crab-eating foxes and maned wolves. The data herein presented for rebound tonometry are new for both species.

Objective To describe ocular anatomical features and to determine tear production and tonometry in normal anesthetized ring-tailed coati (Nasua nasua). Animals Eight male and seven female ring-tailed coatis (30 eyes) were evaluated, with ages ranging from 7 months to 10 years old. Procedures The animals were anesthetized with isoflurane and had STT 1, rebound and applanation tonometry, and palpebral fissure length (PFL) measured in both eyes. Rebound tonometry was measured with both TonoVet® and TonoVet Plus®. All eyes were evaluated with slit-lamp biomicroscopy. Following pharmacological mydriasis, direct fundoscopy was performed. ANOVA and Tukey tests were used for the data analysis. Results There were upper and lower eyelids, as well as a third eyelid. Eyelashes were present on the upper eyelid, while meibomian glands openings were visible on both. The bulbar conjunctiva was pigmented. The pupil was obliquely horizontally ovoid and teardrop shaped when miotic. The color of the iris and tapetum lucidum varied with age. The optic disk was round, and the retina was holangiotic. The mean ± standard deviation values obtained were as follows: STT: 2.50 ± 2.39 mm/min; rebound tonometry: 9.50 ± 2.43 mmHg (TonoVet®, calibration P), 14.60 ± 2.82 mmHg (TonoVet®, calibration D), 18.93 ± 3.99 mmHg (TonoVet Plus®, calibration dog); applanation tonometry: 18.66 ± 4.16 mmHg; PFL: 10.98 ± 1.67 mm. Conclusions and clinical relevance Anatomical and clinical ophthalmic data presented in this study are unprecedented for this species. The results can be used as clinical reference parameters, allowing for better care of these species. The lack of data for the Procyonidae family must be regarded as an incentive for more studies.

OBJECTIVE To describe the morphology of goblet cells of the eyelid conjunctiva in dogs using transmission and scanning electron microscopy. ANIMAL STUDIED Ten dogs, both male and female of different breeds, with no ocular changes were examined (20 eyes). PROCEDURES Ten samples of conjunctiva were collected and processed for scanning and transmission electron microscopy (SEM and TEM), while another 10 samples were stained with Schiff's periodic stain (SPA) and alcian blue, pH 2.5, and analyzed using light microscopy. RESULTS Scanning electron microscopy revealed several points of mucus extrusion in the free apical portion of the goblet cells as well as a wide distribution of lymphoid follicles and macrophages intermingling with the microvilli of palpebral epithelium cells. TEM revealed normal goblet cells that were predominantly oval with wide cytoplasm of different diameters, and large vesicles with heterogeneous granules and free edges, suggesting the release of mucus content onto the conjunctival surface. Cytoplasmic organelles, such as the Golgi apparatus, endoplasmic reticulum, and a high number of mitochondria were also observed. All the samples were positive for SPA and alcian blue staining. CONCLUSION This is the first study to evaluate the goblet cells of the eyelid conjunctiva in healthy dogs using electron microscopy techniques. These results are useful for comparing the palpebral conjunctiva of dogs without ocular changes to palpebral conjunctiva of dogs and other species with ocular changes.

The establishment of parameters for tear production in different species is important for better understanding eye´s health and is one of the components of the ophthalmic semiological technique. Particularities derived from the anatomophysiology of non-domestic species induce the search for more reliable methodologies. The aim was to evaluate and compare tear production of white-eared opossum (Didelphis albiventris) and Brazilian common opossum (Didelphis aurita) by three different methods. Fifteen individuals of each species, juveniles, healthy, of both sexes, with 60 to 90 days of life, were physically restrained. Phenol red thread test (PRTT), endodontic absorbent paper point tear test (EAPPTT) and modified -Schirmer tear test (mSTT) were performed. PRTT was the most difficult to perform because of the wire malleability, while EAPPTT was more feasible for both species. The median ± semi-quartile range for PRTT were 19.79±2.61mm/15 “and 5.22±2.92mm/15”, for EAPPTT were 16.25±1.82mm/min and 10.9±3.04mm/min, and for STTm were 0±1.63mm/min and 0±1.63mm/min for white-eared opossum and Brazilian common opossum respectively. There was no difference between the right and left eye neither sex. A significant difference was obtained for the same test to different species. No significant correlation was found between the tests for both species. The description of tear production parameters for juvenile white-eared opossum and Brazilian common opossum may be used as a tool, which will allow the early diagnosis of ocular diseases. RESUMO: O estabelecimento do parâmetro de produção lacrimal nas diferentes espécies é importante para o entendimento da saúde do olho e é um dos componentes da semiotécnica oftálmica. Particularidades derivadas da anatomofisiologia das espécies não domésticas induzem a busca de metodologias que sejam mais fidedignas aos parâmetros. Objetivou-se com este estudo avaliar e comparar a produção lacrimal de gambás-de-orelha-branca (Didelphis albiventris) e gambás-de-orelha-preta (Didelphis aurita) por três diferentes métodos. Quinze indivíduos de cada espécie, juvenis, hígidos, de ambos os sexos, com 60 a 90 dias de vida, foram contidos fisicamente para realização do teste lacrimal do vermelho de fenol (TLVF), da ponta de papel absorvente estéril e do teste lacrimal de Schirmer modificado (TLSm). O TLVF foi o mais difícil de ser executado devido à maleabilidade do fio, enquanto a TEPA se mostrou mais exequível para ambas as espécies. A mediana ± intervalo semi-interquartil para o TLVF foi de 19,79±2,61mm/15” e 5,22±2,92mm/15”, para a TEPA foram de 16,25±1,82mm/min e 10,93±3,04mm/min, e para o TLSm foram de 0±1,63mm/min e 0±1,63mm/min, para gambás-de-orelha-branca e gambás-de-orelha-preta, respectivamente. Não houve diferença entre o olho direito e esquerdo e nem quanto ao sexo. Obteve-se diferença significativa para um mesmo teste entre as espécies. Não foi encontrada correlação significativa entre os testes para ambas as espécies. A quantificação da porção aquosa da lágrima poderá auxiliar no diagnóstico precoce de doenças oculares nas espécies estudadas.

Resumo Objetivou-se verificar a prevalência da leishmaniose visceral canina (LVC) em área periurbana com foco de transmissão no Distrito Federal (DF) e também avaliar a prevalência de coinfecções como dirofilariose, anaplasmose, erliquiose e doença de Lyme em cães sororreagentes para LVC. Inicialmente, amostras de soros dos cães da área de estudo foram testadas à reação imunocromatográfica que contém dois antígenos recombinantes ̶ rK39 e rK26 − (DPP) para Leishmania sp. O soro dos animais reagentes ao teste de DPP foi confirmado para LVC com ELISA. As amostras reagentes a ambos os testes foram analisadas para possíveis coinfecções através do teste de SNAP (IDEXX 4Dx Plus). Foram avaliados 240 cães, dos quais 132 (55%) obtiveram resultados reagentes para DPP e para ELISA concomitantemente, sendo diagnosticados com LVC. Destes, 26 (20%) foram reagentes para Ehrlichia canis ou E. ewangii, 9 (7%) apresentaram positividade para Anaplasma phagocytophilum ou A. platys e, nessas amostras que se apresentaram reagentes, observou-se a ocorrência de coinfecção de anaplasmose, erliquiose e leishmaniose em 3 (2,3%) animais. Verificou-se alta prevalência da LVC na região periurbana do DF, destacando-se a necessidade de diagnóstico mais preciso quanto a coinfecções que possivelmente podem influenciar no prognóstico e manifestação do quadro clínico desses pacientes. Abstract The aim of this study was to verify the prevalence of Canine Visceral Leishmaniasis (CVL) in periurban area focusing on transmissions that occurred on Distrito Federal (DF), and also, evaluate the prevalence of co-infections like dirofilariosis, anaplasmosis, ehrlichiosis and Lyme disease in dogs seroreagents to CLV. Initially the serum of the dogs inhabitants of the study area was tested according to the immunochromatographic reaction that contained two recombinant antigens - rK39 e rK26 - (DPP) to Leishmania sp. The animal plasma that reacted to the DPP test was confirmed for CVL with ELI-SA. Through confirmation of diagnose of VL by both tests, the samples were analyzed for possible co-infections through SNAP test (IDEXX 4Dx Plus). 240 dogs were tested, 132 (55%) of which obtained reacting results for DPP and for ELISA concomitantly, being diagnosed with CVL. Amongst those, 26 (20%) were positive for Ehrlichia canis or E. ewangii, meanwhile 9 (7%) presented positive results for Anaplasma phagocytophilum or A. platys, from those samples that showed to be positive, co-infection of anaplasmosis, ehrlichiosis and leishmaniasis was observed in 3 (2.3%) dogs. The high prevalence of CVL was observed in the periurban region of DF, highlighting the need for more precise diagnosis regarding co-infections that may possibly influence on the prognosis and clinical manifestation of these patients.

RESUMO A avaliação proteica do humor aquoso (HA) pode ser utilizada como método diagnóstico nas uveítes. Entretanto, estudos sobre as proteínas nesse fluido, em equinos hígidos, são escassos e apresentam variações conforme a metodologia empregada. Dessa forma, objetivou-se realizar a análise proteica e citológica do HA nessa espécie, bem como verificar sua correlação com as proteínas plasmáticas. Foram avaliados 13 equinos adultos (26 olhos), sem raça definida, machos ou fêmeas. Mediante aqueocentese, foi coletado 0,5 mL de humor aquoso de cada olho. Cada amostra foi encaminhada para quantificação proteica pelo método de Bradford modificado e pela eletroforese em gel de poliacrilamida - dodecil sulfato de sódio (SDS-PAGE), bem como para avaliação citológica. Por meio de venopunção, coletou-se sangue para determinação da concentração de proteínas séricas. Treze olhos (50% das amostras) apresentaram valor proteico médio de 40,3 mg/dL±6,45 e a eletroforese demonstrou presença de proteínas de massas mais elevadas que 43 KDa. Houve ausência de células em 96,15% das amostras (25 olhos). Equinos hígidos apresentaram baixa concentração de proteínas no HA. Já a correlação entre proteína no humor aquoso/proteína plasmática total foi de 0,56%. ABSTRACT Evaluation of equine aqueous humor (AH) proteins can help the diagnosis of uveitis. However, studies on proteins in this fluid in healthy horses are scarce and present variations according to the methodology employed. This study aimed to perform protein analysis and cytology of equine aqueous humor of healthy horses and verify its correlation with plasmatic proteins. Thirteen adult horses (26 eyes), mixed breed, male or female were evaluated. A volume of 0.5 mL of aqueous humor was collected through aqueocentesis from both eyes. The samples were submitted to protein quantification by modified Bradford method and to sodium dodecyl sulphate - polyacrylamide gel electrophoresis (SDS-PAGE), and to cytological evaluation. Blood was collected for determination of plasmatic protein concentration. Thirteen eyes (50% of the samples) had values larger than zero by the Bradford method, with an average of 40.3 mg/dl±6.45. Electrophoresis showed presence of higher masses of proteins (43 KDa). There were no cells in 96.15% of the samples (25 eyes). Healthy equines presented low protein concentration in the HA. The ratio between protein concentration in the aqueous humor / total plasma protein of 0.56%.

Keratomycosis in the horse exists in several unique clinical forms. This paper discusses the diagnosis and clinical management of keratomycosis in the horse associated with tear film instability, epithelial keratopathy, subepithelial infiltrates, superficial and deep ulcers, plaques, melting ulcers, descemetoceles, iris prolapse, and stromal abscesses. Prompt diagnosis and aggressive treatment of equine keratomycosis can make a major difference in the maintenance of a cosmetic and visual eye.

Resumo Este trabalho comparou seis cadáveres de cães, sem predileção por raça, idade ou sexo, com peso entre 2 e 10 kg, provenientes da Diretoria de Vigilância Ambiental do Distrito Federal. Os cadáveres, cujos sistemas vasculares foram limpos com solução salina supersaturada, solução de Larssen modificada e água comum, foram divididos em três grupos aleatórios, respectivamente. EM seguida foram conservados com solução de Larssen modificada na proporção de 10% de seu peso corporal, objetivando-se terminar a durabilidade como modelo para o treinamento cirúrgico. Após seis sucessivos congelamentos e descongelamentos, nos quais foram realizadas cirurgias visando avaliar a resistência, cor, odor, maleabilidade e grau de autólise tecidual através de análises histológicas de coração, fígado, baço, intestino e encéfalo, ficou determinado que todos os grupos apresentaram boa qualidade para treinamento cirúrgico, permitindo cirurgias de órgãos cavitários até o terceiro descongelamento, cirurgias da conjuntiva bulbar por até quatro descongelamentos e cirurgias ortopédicas por até seis descongelamentos, ficando inviáveis a partir deste ponto, devido ao elevado grau de autólise tecidual. O grupo conservado com solução salina supersaturada se destacou por quase não desprender odor desagradável, além do encéfalo e do coração serem os únicos órgãos que praticamente não apresentaram alterações macro e microscópicas nos três primeiros descongelamentos. Abstract This study compared six dog cadavers, with no predilection for breed, age, or sex, weighing between 2 and 10 kg, from the Environmental Monitoring Directory of the Federal District, Brazil. Animals were divided into three random groups. The vascular systems were cleaned with supersaturated saline, modified Larssen solution, and common water, respectively, followed by preservation with modified Larssen solution at 10% of body weight, aiming to determine the durability as a model for surgical training. Surgeries were performed in the period between six successive freezing and thawing cycles to evaluate the resistance, color, odor, flexibility and degree of tissue autolysis through histological analysis of heart, liver, spleen, intestine, and brain. All the groups showed good quality for surgical training, allowing cavity organs surgeries until the third thawing, bulbar conjunctiva surgeries until the fourth thawing, orthopedic surgeries for up to the sixth thawing, becoming unworkable from this point, due to the high degree of tissue autolysis. The group of cadavers preserved with supersaturated saline solution stood out by hardly giving off unpleasant smell; in addition, brain and heart are the only organs that practically did not show macroscopic and microscopic changes in the first three thawing cycles.

The aim of this study was to establish reference values for selected ophthalmic diagnostic tests in healthy blue-and-yellow macaws. We investigated a total of 35 adult macaws (70 eyes) of undetermined sex and with an average weight of 1 kg, who were living in captivity in the Federal District, Brazil. Tear production using the Schirmer tear test (STT), normal conjunctival flora, intraocular pressure (IOP) using a rebound tonometer and horizontal palpebral fissure length (HPFL) were evaluated. In this study, 84.1% of samples were positive for microbial growth. Bacteria, fungi and yeasts were isolated, and Staphylococcus spp. (21.9%) and Bacillus spp. (26.8%) were the most frequently isolated microorganisms. The mean value for STT was 7.6±4.6mm/min in the right eye (OD) and 6.6±4.4mm/min in the left eye (OS) (median = 7,11±0,76mm/min). Mean IOP was 11.4±2.5mm Hg OD and 11.6±1.8mm Hg OS (median = 11.49±0.22mm Hg), prior to anesthesia, and 7.6±2.4mm Hg OD and 7.8±1.8mm Hg OS (median 7.71±0.08mmHg) after anesthesia. The IOP was significantly lower when the animals were under anesthesia as compared to when they were conscious (p≤0.05). Horizontal palpebral fissure length was 11.7±0.1mm OD and 11.8±0.1mm OS (median = 11.72±0.07mm). The STT showed a positive correlation with palpebral fissure measurement for this species. These selected ophthalmic reference values will be particularly useful in diagnosing pathological changes in the eyes of blue-and-yellow macaws. RESUMO: Objetivou-se determinar os valores normais para testes oftálmicos diagnósticos selecionados para a Arara Canindé. Trinta e cinco Ara ararauna (70 olhos), de sexo indeterminado, adultas, com peso médio de 1kg e provenientes de cativeiro no Distrito Federal, foram avaliadas. Aferiram-se a produção lacrimal pelo Teste lacrimal de Schirmer (TLS), a avaliação microbiológica da conjuntiva ocular, a pressão intra-ocular (PIO) utilizando a tonometria de rebote e o comprimento horizontal da rima palpebral Neste estudo 84.1% das amostras analisadas foram positivas para crescimento microbiológico. Bactérias, fungos e hifas foram isolados e Staphylococcus spp. (21.9%) e Bacillus spp. (26.8%) foram isolados mais frequentemente. Os valores médios do teste de Lacrimal de Schirmer (TLS) foram de 7.6±4.6 e 6.6±4.4mm/min para olhos direito (OD) e esquerdo (OE), respectivamente (média = 7,11±0,76mm/min). A pressão intraocular média foi de 11.4±2.5 (OD) e 11.6±1.8mmHg (OE) anteriormente à anestesia (média 11,49±0,22 mmHg) e 7.6 ± 2.4 mmHg (OD) e 7.8 ± 1.8 mm Hg (OE) (média 7,71±0,08mm Hg) após a anestesia, verificando-se que a PIO foi significativamente menor quando os animais se encontravam sob anestesia comparativamente ao momento em que não estavam anestesiados. O comprimento horizontal da rima horizontal palpebral foi de 11.7±0.1mm OD e de 11.8±0.1mm OE (média 11,72±0,07mm). Verificou-se correlação positiva do TLS com o comprimento da fissura palpebral para a espécie estudada. Estes valores de referencia serão úteis no diagnóstico de alterações oculares da Arara Canindé.

The collared anteater ( Tamandua tetradactyla ) is adapted to a variety of habitats. It is a solitary species for which no reference values for ophthalmic tests have been established. Eight animals ranging from 1 to 4 yr of age, two males and six females, were manually restrained for assessment. Ophthalmic tests included evaluation of tear production by Schirmer tear test 1 (STT1), endodontic absorbent paper point tear test (EAPPTT), palpebral fissure length (PFL), culture of the conjunctival bacterial flora, and antimicrobial susceptibility test. Median ± semi-interquartile range (S-IQR) STT1, EAPPTT, and PFL were 8.50 ± 4.13 mm/min, 14.13 ± 3.24 mm/min, and 15.91 ± 2.51 mm, respectively. Bacterial growth was present in 100% of the samples, with predominance of Gram-positive bacteria (70.27%). Staphylococcus spp. was the most frequently isolated genus. Antimicrobial susceptibility test showed sensitivity of Staphylococcus epidermidis and Staphylococcus spp. to neomycin, tobramycin, and gentamicin. The results in this study can benefit the determination of reference values for different diagnostic techniques, and may be used as a guide for diagnosis and treatment of ocular diseases in collared anteaters.

O mastocitoma é a neoplasia cutânea maligna de maior frequência em cães. Apesar do estudo e do desenvolvimento de diversos marcadores prognósticos na tentativa de prever o comportamento biológico deste tipo de neoplasia, a graduação histológica continua sendo utilizada como principal delineador prognóstico para os animais acometidos, mesmo não conseguindo prever o comportamento de mastocitomas de diferenciação intermediária. Diferentes marcadores de proliferação e atividade celular vêm sendo testados com resultados promissores, entretanto, em sua maioria, demandam técnicas específicas de coloração e imuno-histoquímica que, ainda hoje, são de alto custo e muitas vezes não estão facilmente disponíveis. O índice mitótico é um método indireto de mensuração da atividade proliferativa celular, que pode ser contabilizado em uma lâmina comum de avaliação histológica e estudos vêm determinando-o como importante marcador prognóstico para o mastocitoma canino. Dada a recente publicação sugerindo nova graduação em dois graus (alto e baixo) e indisponibilidade das técnicas específicas utilizadas na determinação de outros fatores prognósticos, objetivou-se avaliar o poder prognóstico das diferentes classificações, associando-as à sobrevida destes animais e comparando com o índice mitótico. Apesar de isoladamente ambas as classificações histológicas apresentarem associação com a sobrevida (P0,05). O índice mitótico foi o fator prognóstico mais confiável para sobrevida, independente do ponto de corte utilizado (P0,05), and the mitotic index was the most significant prognostic factor for survival, regardless of the cut-off point used (P

Introduction Human amniotic membrane (AM) has been used as a biomaterial for sur-gical wound skin and ocular surface reconstruction for several years. Currently, equineAM has been used for corneal reconstruction in several animal species, and appears tohave the same properties as human AM. Despite the observed positive healing abilitiesof this tissue in horses with ulcerative keratitis the proteins of equine AM have notbeen described.Objective To identify proteins known to be associated with corneal healing fromfrozen equine AM.Procedures Placentas were acquired from healthy live foal births from a local Thor-oughbred breeding farm. The amnion was removed from the chorion by blunt dissec-tion, washed with phosphate-buffered saline (PBS), and treated with 0.05% trypsinand 0.02% ethylene diaminetetraacetic acid in PBS. Amnion was attached to nitrocel-lulose paper (epithelial side up), and cut into 4 9 4 cm pieces. The sheets were frozenat 80 °C. The protein samples were solubilized, and analyzed by 2D gel electropho-resis and shotgun proteomics.Results A reference identification map of the equine AM proteins was produced and149 different proteins were identified. From gel-based proteomics, 49 spots wereexcised and 43 proteins identified by liquid chromatography coupled to tandem massspectrometry (LC-MS/MS). Shotgun proteomics identified 116 proteins with an over-lap of 10 proteins in both analyses.Conclusions We have described a reference map for equine AM proteins that mayprovide a background to explain the positive results found in horses with ulcerativekeratopathies using this biomaterial.Key Words: amniotic membrane, dermatopontin, horse, lumican, protein, proteome

Foram utilizados 10 cães de diferentes idades e da raça Poodle, apresentando graus variados de catarata. Os animais foram submetidos ao exame oftalmológico e ultrassonográfico. Por meio da ultrassonografia avaliaram-se a anatomia ultrassonográfica dos bulbos oculares e a espessura axial da lente (EAL). Por meio do modo Doppler verificaram-se o tipo de fluxo sanguíneo da artéria oftálmica e seus índices vasculares, a velocidade sistólica (VS), o índice de resistência (RI) e a pulsatividade (PI). Os valores de EAL para olho direito (OD) foi de 5,89±1,05 e para o olho esquerdo (OE) de 6,07±1,32. Por meio do Doppler, observaram-se VS para OD de 26,54±7,05 e VS para OE de 29,21±11,18; PI para OD de 1,89±0,61 e PI para OE de 1,7±0,35; RI para OD de 0,76±0,1 e PI para OE de 0,72±0,09. Concluiu-se que o modo Doppler Triplex mostrou-se importante para determinação das medidas dos índices vasculares da artéria oftálmica, podendo ser utilizada para o acompanhamento de alterações hemodinâmicas nos olhos dos animais acometidos e no acompanhamento da terapia de doenças oculares. The findings of b-mode and especially triplex Doppler ocular ultrasound in the evaluation of 10 Poodle dogs with cataracts, which bring a contribution not yet reported in veterinary medicine, were reported. Ten Poodle dogs of varied ages and presenting cataracts were used. All animals were evaluated for ophthalmic and ultrasound examination. The ultrasound examination allowed the evaluation of the sonographic anatomy of the eye and measurement of the axial thickness of the lens (ATL). Using the Doppler mode, the blood flow of the ophthalmic artery and its vascular indexes, systolic velocity (SV), resistive index (RI) and pulsatility index (PI) were measured. Values found for ATL were 5.89±1.05 for the right eye (OD) and 6.07±1.32 for the left eye (OS). Values found using Doppler evaluation were SV OD: 26.54±7.05 and SV OS: 29.21±11.18; PI OD: 1.89±0.61 and PI OS: 1.7±0.35; RI OD: 0.76±0.1 and RI OS: 0.72±0.09 (OS). It was concluded that triplex Doppler was important for the determination of vascular indexes of the ophthalmic artery, which can be used for monitoring animals with hemodynamic alterations of the eyes and monitoring the therapy of ocular diseases.

The aim of this study was to compare two methods of tear sampling for protein quantification. Tear samples were collected from 29 healthy dogs (58 eyes) using Schirmer tear test (STT) strip and microcapillary tubes. The samples were frozen at -80ºC and analyzed by the Bradford method. Results were analyzed by Student's t test. The average protein concentration and standard deviation from tears collected with microcapillary tube were 4.45mg/mL ±0.35 and 4,52mg/mL ±0.29 for right and left eyes respectively. The average protein concentration and standard deviation from tears collected with Schirmer Tear Test (STT) strip were and 54.5mg/mL ±0.63 and 54.15mg/mL ±0.65 to right and left eyes respectively. Statistically significant differences (p

Lubrificantes oculares são usados como suplementos de uma ou mais camadas do filme lacrimal. São frequentemente prescritos para o tratamento da ceratoconjuntivite seca (CCS) no homem e em outras afecções da superfície ocular. Seu uso também pode gerar proteção da superfície ocular e promover regeneração epitelial. Os principais componentes de sua formulação são os agentes lubrificantes e as principais propriedades são a composição eletrolítica, a osmolaridade e a presença de conservantes. Embora lacrimomiméticos não sejam o tratamento da CCS em cães, eles podem ser utilizados como terapia adjuvante. O conhecimento de suas propriedades auxiliará na melhor opção terapêutica. Ocular lubricants are used to supplement one or more layers of the lacrimal film. They are often prescribed to treat keratoconjunctivitis sicca (KCS) and other diseases of ocular surface in humans. These lubricants may also protect the ocular surface and promote epithelial regeneration. The active component of ocular lubricants is the lubricating agent. The key properties of different lubricating agents are the electrolyte composition, osmolarity, and addition of preservatives. Although lacrimomimetics are not typically used to treat KCS in dogs, they can be used as an adjunctive therapy. Knowledge of the properties of lacrimomimetics will help in making the appropriate therapeutic choice.

Mammary gland tumors are the most common type of tumors in bitches but research on survival time after diagnosis is scarce. The purpose of this study was to investigate the relationship between survival time after mastectomy and a number of clinical and morphological variables. Data was collected retrospectively on bitches with mammary tumors seen at the Small Animal Surgery Clinic Service at the University of Brasília. All subjects had undergone mastectomy. Survival analysis was conducted using Cox's proportional hazard method. Of the 139 subjects analyzed, 68 died and 71 survived until the end of the study (64 months). Mean age was 11.76 years (SD=2.71), 53.84% were small dogs. 76.92% of the tumors were malignant, and 65.73% had both thoracic and inguinal glands affected. Survival time in months was associated with age (hazard rate ratios [HRR] =1.23, p-value =1.4x10-4), animal size (HRR between giant and small animals =2.61, p-value =0.02), nodule size (HRR =1.09, p-value =0.03), histological type (HRR between solid carcinoma and carcinoma in a mixed tumor =2.40, p-value =0.02), time between diagnosis and surgery (TDS, with HRR =1.21, p-value =2.7x10-15), and the interaction TDS*follow-up time (HRR =0.98, p-value =1.6x10-11). The present study is one of the few on the subject matter. Several important covariates were evaluated and age, animal size, nodule size, histological type, TDS and TDS*follow up time were identified as significantly associated to survival time. Resumo: Os tumores da glândula mamária são o tipo mais comum de tumores em cadelas, porém, estudos sobre o tempo de sobrevida após o diagnóstico são escassos. Objetivou-se investigar a relação entre o tempo de sobrevida após a mastectomia, bem como variáveis clínicas e populacionais. Coletaram-se dados retrospectivos referentes a cadelas com tumores mamários atendidos no Serviço de Clínica Cirúrgica de Pequenos Animais da Universidade de Brasília e submetidas à mastectomia. A análise de sobrevida foi realizada mediante o método de Cox de risco proporcional. Dos 139 animais incluídos neste estudo, 68 morreram e 71 sobreviveram até ao final da conclusão deste traballho (64 meses). A média de idade foi de 11,76 anos (DP=2,71), 53,84% dos cães eram pequenos. Dentre os tumores, 76,92% eram malignos, e 65,73% tiveram as duas glândulas torácicas e a inguinal afetadas. O tempo de sobrevida em meses foi associado à idade (taxa de razão de risco [HRR] =1,23, p valor =1.4x10-4), o tamanho do animal (HRR entre animais gigantes e pequenos = 2,61, p=0,02), tamanho do nódulo (HRR=1,09, p valor =0,03), tipo histológico (HRR entre carcinoma sólido e carcinomas em tumor misto =2,40, p=0,02), tempo decorrido entre o diagnóstico e a cirurgia (TDC, com HRR =1,21, p valor =2,7 x10-15), e a interação TDC*tempo de seguimento (HRR = 0,98, p valor = 1.6x10-11). O presente estudo é um dos poucos sobre o assunto. Várias covariáveis importantes foram avaliadas e idade, tamanho do animal, o tamanho do nódulo, tipo histológico, TDC e TDC*tempo de seguimento foram identificados como significativamente associado ao tempo de sobrevida.

Purpose The ability of human newborns to produce tears has been a subject of controversy in the literature since the mid-20th century, and there has been considerable debate as to whether they are able to produce tears. Recently, it was established that total tear secretion (reflex + basal) in full-term infants is similar to those of adults whereas both reflex and basal tear production is reduced in premature babies. The objectives of this study were to assess whether newborn dogs have measurable aqueous tear production at the fourth week of life and to evaluate a modified Schirmer tear test (mSTT) as a useful method for measuring neonatal tear production in dogs. Methods Thirty four-week-old healthy puppies from six litters were evaluated. A control group was composed of 10 normal adult dogs. The mSTT strips were obtained by cutting a 5 mm-wide strip in half (making two 2.5 mm-wide strips). The mSTT1 was performed in puppies and adult dogs. Values were compared using t-tests. Results In neonates, the average value for the mSTT1 was 13.6 ± 3.07 (range = 7–19 mm/min), which was significantly lower in neonates than in adult dogs (23.25 ± 3.5, range = 17–30 mm/min, P

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 ocular. O tratamento clínico para a resolução da doença corneal e o controle da uveíte reflexa deve ser agressivo e associado, muitas das vezes, à terapia cirúrgica. Este artigo discorre sobre a fisiopatologia e o tratamento da ceratomicose em equinos. Environmental and behavioral factors make horses susceptible to corneal and conjunctival lesions, since these structures are constantly exposed to bacteria and fungi specially Aspergillus spp. and Fusarium spp. Bacterial and fungal ulcerative keratitis, as well as non-ulcerative fungal keratitis such as stromal abscess, are frequent in horses. A cascade effect follows the initial lesion which triggers the release of inflammatory cytokines followed by an acute and severe infiltrate of polymorphonuclear cells in the cornea. The cornea becomes susceptible to the activity of proteolytic enzymes released by microorganisms and polymorphonuclear cells, resulting in stromal degradation and ocular perforation. The medical treatment targeting the corneal disease and the controlling of reflexive uveitis should be aggressive and surgical therapy should be associated in most of the cases. This paper reviews the pathophysiology of keratomycosis in horses and specific aspects of the treatment in this species.

Trinta animais distribuídos em cinco grupos (n=6) foram estudados por até 60 dias de pós-operatório. A avaliação clínica revelou manifestações moderadas de edema, blefaroespasmo e fotofobia ao segundo dia, evoluindo para formas discretas ou ausentes a partir do sétimo dia, período em que se observou, clinicamente, reparo do defeito corneal. A histopatologia revelou uma fina camada de células escamosas, recobrindo a área lesada já aos sete dias, com discreto infiltrado de células polimorfonucleares. Observaram-se vasos no epitélio a partir do 15o dia, com regressão ao 48o dia. A marcação com o anticorpo Ki67 mostrou aumento de células em proliferação aos 15 dias no epitélio e aos 30 dias no estroma. Nesse período, ocorreram remodelamento e adesão epitealial. Considerando a boa integração do implante, admite-se a membrana de celulose como um bom material a ser utilizado em ceratoplastia lamellar. The clinical, histopathological and immunohistochemical features of the cornea were investigated in adult male New Zealand rabbits submitted to lamellar keratoplasty with microfibrillar cellulose membrane. Thirty animals were divided into five groups (n=6) and evaluated up to 60 days after surgery. Clinical examination revealed moderate manifestations of edema, blepharospasm and photophobia on the second day, which became mild or disappeared after the seventh day. This period was characterized clinically by repair of the corneal defect. Histopathological analysis showed the presence of a thin layer of squamous cells covering the damaged area as early as 7th day, accompanied by a mild infiltrate of polymorphonuclear cells. Blood vessels were observed in the epithelium after the 15th day, which had regressed by day 48. Ki67 antibody labeling showed an increase of proliferating cells in the epithelium by the 15th day and in the stroma by day 30. Remodeling and epithelial adhesion were observed during this period. Microfibrillar cellulose membrane (Bionext®) used for lamellar keratoplasty was found to yield good results considering the good integration of the implant.

Objetivou-se descrever, por meio de tomografia computadorizada, o trajeto do canal mandibular (CM) em 20 gatos sem raça definida, com ausência de alterações na cavidade oral, provenientes do Centro de Controle de Zoonoses do Distrito Federal. Foram realizados cortes tomográficos com 2mm de espessura, acompanhando todo o trajeto do CM, tendo como referência a região do forame mandibular, as raízes distais e mesiais dos dentes pré-molares e molares e o forame mentoniano, obtendo-se medidas desde o CM até as faces vestibular, lingual, ventral e alveolar (profundidade) do corpo da mandíbula, bem como seu diâmetro. Pôde constatar que o CM manteve-se no aspecto lingual do corpo da mandíbula desde o forame mandibular até a raiz mesial do 1º pré-molar, onde se deslocou para a face vestibular, emergindo no forame mentoniano. Com relação à profundidade, seu trajeto sofreu declive a partir do forame mandibular até a região da raiz mesial do 1º molar, onde alcançou seu ponto mais profundo para prosseguir em suave ascensão até o forame mentoniano. Os dados apresentados contribuem para o estudo anatômico da mandíbula de gatos, bem como auxiliam no melhor planejamento e execução de procedimentos cirúrgicos na mandíbula dessa espécie. ABSTRACT This study aimed to describe the path of the mandibular canal (MC), using computerized tomography, in twenty mongrel cats, with no changes in the oral cavity, from the Zoonosis Control Center of the Federal District. 2mm thick tomographic sections were taken following the entire path of the mandibular canal, considering as reference the region of the mandibular foramen, the distal and mesial roots of premolar and molar teeth, and mental foramen, obtaining measurements from the MC until the buccal, lingual, ventral and alveolar (depth) surfaces of the mandibular body as well as its diameter. MC remained on the lingual aspect of the mandibular body from the mandibular foramen to the mesial root of the first premolar, where it displaced to the buccal surface, emerging from the mental foramen. Regarding the depth, we observed a downward path from the mandibular foramen to the mesial root of the first premolar, where it reached its deepest point, the path continued in gentle ascent until to the mental foramen. Our data contribute to the anatomical study of the feline jaw and allow a better planning and execution of surgical procedures in the mandible of this species.

Objective To describe the tear ferning test (TFT) in healthy horses and its correlation with other parameters for evaluating the ocular surface. Animals studied Thirty male and female adult healthy horses (60 eyes), of no defined breed. Procedures Tear sample was collected with a microcapillary tube, placed on the surface of a glass slide, and allowed to dry at room temperature. The crystallization pattern was classified according to Rolando (Chibret International Journal Ophthamology, 1984; 2, 32). The program STEPanizer© stereology tool, version 1.0, was utilized for counting points on the digitally captured crystallization image. A conjunctival biopsy was performed. Results Tear ferning test was classified as Type I in 18 eyes (30%), Type II in 31 eyes (51.7%), and Type III in 11 eyes (18.3%), at a mean temperature of 27.3 ± 1.5 °C and relative humidity of 61.5 ± 5.7%. In the Type I crystallization, the count varied between 27 and 36 points (mean: 33.27 ± 2.40), in Type II between 22 and 31 points (25.42 ± 1.95), and in Type III between 13 and 25 points (16.82 ± 3.76). There was no statistical difference or correlation between the right and left eyes, nor was there a statistically significant influence (P
