Corneal ulcer in a sheep - treatment with third eyelid flap

Background: Corneal ulcers are frequently reported in the literature in several species, however, the treatment of traumaticlesions on the corneal surface of ruminants is still poorly described. The use of the third eyelid flap is questioned whenapplied to deep ulcers, since the technique prevents the evolutionary follow-up of corneal healing and compromises care.However, several authors report its successful use for the treatment of superficial and deep corneal ulcers. This techniqueprotects the ocular surface and prevents the occurrence of new lesions or their aggravation. The aim of this study was toreport the treatment of corneal ulcers in sheep through the third eyelid flap associated with the use of topical antibiotics.Case: A 2-year-old male Dorper sheep, with ocular discomfort, conjunctival hyperemia and mucopurulent secretion in theleft eye, was assisted in a private rural property in the West region of Bahia, Brazil. The owner reported that before seeking veterinary help he used a spray based on oxytetracycline and hydrocortisone, which worsened the animals condition.Upon inspection, it was observed eyelid asymmetry, slight lateralization of the head to the left, periorbital alopecia onthe left face, intense blepharospasm in the left eye, with projection of the third eyelid occurring at times. The ophthalmicexamination was performed after application of anesthetic eye drops based on proxymetacaine to reduce eye discomfort.A corneal stromal lesion, edema and fibrovascular tissue in the left eye were identified, but the cause of the lesion was notdefined, with lagophthalmia, entropion, dystychiasis or ectopic cilia being ruled out. So, it was suggested that the lesionhad occurred by a foreign body, such as dust...(AU)

Hemangiosarcoma of the third eyelid in an American Pit Bull Terrier

Background: Hemangiosarcoma (HSA) is a malignant neoplasm arising from the endothelial cells of blood vessels. It has fast growth, and severe local infiltration and metastasis power, in addition to risk of hemorrhage due to the fragility of its vessels. HSA develops in dogs aged 8 to 13 years but can affect younger animals too. Ocular involvement in HSA is rare, but when identified, the third eyelid and bulbar conjunctiva close to the limbus are the most affected sites by this neoplasm. This study aimed to report the clinicopathological aspects of a case of HSA in the third eyelid of an American Pit Bull Terrier breed. Case: A 10-year-old male American Pit Bull Terrier with a history of a red hemorrhagic mass on the third eyelid of the left eye was examined at a veterinary clinic. On physical examination, the animal showed signs of ocular discomfort and bleeding. On ophthalmologic examination, a raised red mass, approximately 2 cm in diameter, was identified on the anterior surface of the third eyelid. The mass was surgically excised. The excised tissue fragment was fixed in 10% buffered formalin solution for 24 h and sent for histopathological examination. Macroscopically, the fragment was irregular, soft, and brownish and measured 2.0 × 1.0 × 0.5 cm. Histologically, proliferation of non-delimited and non-encapsulated atypical endothelial cells, which were organized in vascular arrangements forming small lakes filled with red blood cells, was observed. The cells exhibited elongated and basophilic cytoplasm, oval nuclei with coarse chromatin, and evident nucleoli. Moderate anisocytosis and anisocariosis were observed, with no mitotic figures. Epithelial hyperplasia with mild mixed inflammatory infiltrate was noted. Surgical margins were compromised. Sections of neoplastic tissue were processed...

Marsupialization for the treatment of nictitating membrane cyst in a dog: case report / Marsupialização para o tratamento de cisto em membrana nictitante de cão: relato de caso

This study aims to describe the first Brazilian report of a nictitating membrane cyst's surgical treatment in a dog. A 6-month-old female French Bulldog presented at HOSVET-UNIME with a reddish mass-like structure in the medial canthus of both eyes, with a history of recurrent third eyelid gland prolapse previously treated with two surgeries performed at another clinic. Physical examination revealed a third eyelid gland prolapse in the right eye and a cyst in the left eye's third eyelid. The animal was submitted to surgical correction of the right eye's third eyelid prolapse using pocket technique and of the left eye's third eyelid using marsupialization technique for the cyst's treatment. 180 days after th1e surgical procedure no recurrence was observed. The marsupialization technique for the treatment of a third eyelid's lacrimal cyst in a dog allowed the maintenance of its gland and prevented the formation of a new cystic cavity.(AU)

Squamous cell carcinoma in third eyelid of cat / Carcinoma de células escamosas em terceira pálpebra de felino

Background: The third eyelid neoplasms are uncommon in cats. The squamous cell carcinoma are easily found in head and neck of same species, although is unusual in eye region. The more common localization is eyelid and eyeball, being 60 and 15%, respectively. It could be diagnosed by citology, histopathology, imunohistochemistry and molecular biology. The surgery is more effective treatment, because the tumor can be totally removed and it must available surgical margin. The aim of this study was to report a case of squamous cell carcinoma in third eyelid of a cat and show how it was treated with radical surgery.Case: A 11-year-old spayed female domestic short-haired white and black colored cat was presented for evaluation at Maria Dias Teixeira Hospital of Amazonia Federal Rural University (UFRA), of an red ocular mass fast growth in the left eye for 2 months. Physical exam was within normal limits. The animal presented discomfort on the region, when it was manipulated. The mass was ulcerated and blood-tinged ocular discharge, had 3.3 x 2 cm, beginning on third eyelid and overlay all the eyeball. Blood was collated to make exams. Complete blood count and serum chemistry profiles were within normal ranges, but leukocytes were increased and it was treated with Amoxicillin (22 mg/kg).

Prolapso da glândula da terceira pálpebra em cão: relato de caso / Third eyelid gland prolapsed in dog: case report

Fazem-se necessárias atualizações na literatura a respeito do prolapso da glândula da terceira pálpebra, no que diz respeito ao seu tratamento, devido à existência de diferentes técnicas cirúrgicas para sua resolução, com vantagens e desvantagens. O trabalho relata o tratamento cirúrgico, utilizando a técnica de Moore, do prolapso da glândula da terceira pálpebra bilateral, em uma cadela com entrópio bilateral, seis meses de idade e da raça Shar-Pei, atendida no Hospital Veterinário Escola, Moçambique. A técnica de Moore apresentou um bom resultado, e em casos de presença de entrópio bilateral podem ser realizadas ambas as cirurgias no mesmo dia, desde que o entrópio não seja do tipo espástico. O procedimento cirúrgico usando a técnica de Moore continua sendo a técnica cirúrgica de fácil aprendizado, mais simples de se realizar e não afetou a mobilidade da terceira pálpebra.

The updating of the of the prolapse of the third eyelid gland treatment in the literature is pertinent, due to the different surgical techniques for his resolution, with advantages and disadvantages. The work aimed to report the Moore technique in surgical treatment of the bilateral prolapse of the third eye lidgland in a female dog with bilateral entropion, six months, Shar-Peibreed, attended in the Veterinary Hospital School, Mozambique. The Moore technique showed good results andif the bilateral entropionwas not a spastic type, wasable to do the both surgeries in same day. The surgery using the Moore technique continues easy to learn, more simple to do and does not affect the third eyelid mobility.
