“…The superficial gland of the third eyelid in the Sulawesi bear cuscus was positioned between the medial rectus muscle and the ventral rectus muscle of the eyeball and was partially covered by the ventral oblique muscle of the eyeball surrounded by a large periorbital fat body. A similar gland location was found in other animal species (Aldana Marcos et al, 2002;Cazacu, 2010;Dyce et al, 1996;Kempster et al, 2002;Klećkowska-Nawrot & Dzięgiel, 2007;Klećkowska-Nawrot, Nowaczyk, Goździewska-Harłajczuk, Krasucki, et al 2015;Leite, Oliveira, & Baraldi-Artoni, 2013;Martin et al, 1988;Mohammadpour, 2008;Nickel et al, 2004;Nuyttens & Simoens, 1995;Pinard et al, 2003;Schlegel et al, 2001). The superficial gland of the third eyelid has also been recognised in four Australian marsupials: the shortnosed bandicoot (Isoodon macrourus, Peramelidae), the yellow-footed antechinus (Antechinus flavipes, Dasyuridae), the eastern native cat (Dasyurus viverrinus, Dasyuridae) and the tiger cat (Dasyurus maculatus, Dasyuridae) (Sakai & van Lennep, 1984).…”

This study described the anatomy, histology and the histochemical analysis of the eye tunics, the upper and lower eyelid, the third eyelid, the lacrimal gland and the superficial gland of the third eyelid in adult Sulawesi bear cuscus. The eyeball and the eyelids with the orbital glands were harvested immediately post‐mortem. The eyeball in the Sulawesi bear cuscus had a sphere‐like shape. The pupil was round, and the lens was a circular biconvex body. There was neither tapetum lucidum nor Harderian gland. Similarly, there were no eyelashes in the lower eyelid. The lymphoid follicles and the high endothelial venules (HEV) were found in the lymphoid region only in the third eyelid and in the connective tissue of the superficial gland of the third eyelid. The third eyelid in the bear cuscus resembled the letter “T.” The lacrimal gland and superficial gland of the third eyelid were multilobar tubuloacinar glands. The histological analysis and histochemical studies showed that the lacrimal gland in the Sulawesi bear cuscus produced a mucoserous secretion with predominantly serous cells. In contrast, the superficial gland of the third eyelid produced a serous secretion with a single acinus mucous in character.

“…É composto por três camadas, a primeira e mais externa é composta pela córnea e esclera transição entre ambas denominada de limbo esclerocorneano. Ele é aproximadamente esférico em cães e gatos e o tamanho varia entre as espécies e raças (GELLAT, 2013;TURNER, 2010;ORIÁ et al,2011;LEITE et al,2013;MILLER, 2017).…”

RESUMO As fluorquinolonas são antimicrobianos com ampla aplicação na rotina da medicina veterinária. Dentre estas, destaca-se o enrofloxacino, um fármaco que possui espectro de ação antimicrobiana abrangente no organismo animal. Atualmente é uma das maiores classes de agentes antibióticos utilizadas no mundo para o tratamento de infecções bacterianas, tanto Gram-positivas, quanto as Gramnegativas. Assim, tais características a tornam uma frequente escolha para tratamento de várias enfermidades em cães e gatos. Entretanto, na espécie felina, devido ao aumento da dose, frequência de administração, ou infusões rápidas, juntamente ao desconhecimento dos efeitos colaterais, pode ocasionar a degeneração da retina. Tal degeneração causada pelo tratamento com enrofloxacino manifesta-se como cegueira de caráter agudo, geralmente irreversível. Apesar da fisiopatologia deste processo permanecer desconhecida, existem algumas hipóteses prováveis, tal como a deficiência de proteína ABCG2 na barreira hemato retiniana dos gatos, propiciando o acúmulo do fármaco na retina e a ocorrência das alterações posteriores. Os sinais clínicos mais comuns incluem midríase com ausência de reflexos pupilares, relutância ao andar ou pular, hiperreflexia tapetal e atenuação dos vasos retinianos. O diagnóstico pode ser realizado através de exames oftálmicos como a oftalmoscopia direta, analisando o padrão de alterações do fundo de olho, e a eletreorretinografia, que fornece dados captados dos fotorreceptores confirmando a cegueira dos animais. Como não há um tratamento, a profilaxia é a melhor opção para evitar a degeneração de retina nos gatos. O presente trabalho tem como objetivo elaborar uma revisão, que relacione o uso de enrofloxacino em gatos e a degeneração de retina.

This study aimed to reveal the anatomical features of the bovine eye by scanning electron and light microscopic methods. For this purpose, a total of 40 eyes were evaluated. Gross and microscopic characteristics of the cornea, sclera, ciliary body, choroid, iris, and lens were determined. Bowman's and Descemet's membranes of the cornea were quite dense and prominent. Collagen lamellae of the cornea were wavy in the periphery and more parallel to the basal and metachromatic fibroblasts were noted. Three to four ciliary plicae merged to form ciliary processes. The presence of prominent intermediate bands connecting the ciliary plicae was determined. The zonular fibrils merged and attached to the lens in the form of thick zonular bands. A dense corpora nigra was present at the rectangular pupillary border of the iris. Tapetum fibrosum, consisting of polygonal tapetal cells, was in blue-yellow-green color and covered most of the choroid. A complex drainage system consisting of trabecular meshwork, angular aqueous plexus, ciliary sinus, and scleral venous vessels localized in a fairly wide iridocorneal angle was identified. Identifying structural features of the bovine eye is very important and useful for pathological evaluations, understanding species-specific physiological mechanisms and for operative interventions of ruminant species.
