Resumo

Este estudo descreve-se o caso de um canino com cisto de inclusão epitelial corneal. Um cão, sem raça definida, macho de 12 anos, foi atendido apresentando uma massa em seu olho esquerdo, a qual apresentava uma evolução de 5 meses sem resposta positiva a diferentes protocolos terapêuticos. O tutor relatou não haver lesão prévia ou trauma, assim como nenhum sinal de desconforto apresentado pelo animal, como epífora ou blefaroespasmo. O exame oftalmológico revelou uma deformação na estrutura corneana, sem sinais de dor. Alterações em outras estruturas oculares não foram observadas. Associado ao exame oftalmológico e ao resultado da citologia, chegou-se ao diagnóstico de cisto corneal e foi feita a excisão completa por meio de uma ceratectomia lamelar. Devido ao fato da massa não ultrapassar a porção média do estroma, o recobrimento da superfície não foi realizado. Dois meses após a cirurgia, o paciente não apresentou qualquer tipo de secreção ocular ou sinais de dor. Além disso, a córnea não continha neovascularização nem sequelas do processo cicatricial, recuperando sua transparência.


This study described the case of a canine with a corneal epithelial inclusion cyst. A twelve-year-old male dog of undefined race was attended presenting a mass on his left eye, which did not respond to any therapeutic protocols for the last five months. The tutor reported that there was no previous injury or trauma, as well as no signs of discomfort presented by the animal, such as epiphora or blepharospasm. The ophthalmological examination revealed a deformity in the corneal structure, without signs of pain. Alterations in other ocular structures were not observed. Regarding the ophthalmological exam and cytology result, a diagnosis of corneal cyst was obtained and the complete excision by a lamellar keratectomy was done. Since the mass did not exceed the middle portion of the stroma, the surface covering was not performed. Two months after surgery, the patient did not present any type of ocular secretion or signs of pain. Moreover, the cornea did not contain neovascularization or sequelae of the healing process, recovering its transparency.

Background: The eye is an important sense organ responsible for sight. The cornea is the outermost of many eye layers,being predisposed to several lesions, some of them being frequent in small animal clinics meanwhile others are unusualand seldom reported in specialized literature. The stroma abscess is a common condition in horses, but atypical in dogs,it’s a condition in which a microperforation in the corneal epithelium allows microorganisms or a foreign body to penetratethe corneal stroma, and those become inside the cornea after a re-epithelialization, producing an intense inflammatoryresponse. Therefore, this case reports a case of deep stromal abscess in a Shih Tzu dog.Case: A 4-year-old female Shih Tzu, weighing 4.6 kg, was submitted to ophthalmic examination in which the left eyepresented an opaque yellowish-white protruding structure located on the right side, in the center of the cornea (3 o´clockposition), bulbar and palpebral conjunctival hyperemia and congestion, chemosis, blepharospasm, and a moderate amountof mucous discharge. The clinical diagnosis was stromal abscess with reflex uveitis. A differential diagnosis should includeconditions affecting the anterior part of the cornea, such as an epithelial inclusion cyst and a corneal ulcer. The inclusioncyst, contrarily to the corneal abscess, doesn’t cause pain, meanwhile, the corneal ulcer was ruled out by the FluoresceinStaining Test. The recommended treatment was surgical, through lamellar keratectomy, followed by overlapping pedicledconjunctival graft and third eyelid flap. In association with the surgical treatment, oral antibiotics, anti-inflammatory,and opioids, plus topical antibiotics and autologous serum eye drop. Seventy days post-surgery, the previously observedinflammatory signs were no longer present. In the conjunctival graft insertion site perpetuated a scar leucoma with few...

Background: Due to its ocular microflora, the equine species is predisposed to develop mycotic ulcers which, when notproperly treated, can lead to the formation of a stromal abscess. A stromal abscess occurs through the introduction ofmicroorganisms into the corneal stroma. During re-epithelialization, the foreign body is encapsulated, thus creating abarrier that protects bacteria or fungi from treatment with antimicrobial medication. This framework can end up resultingin blindness due to chronic iridocyclitis, putting the animal’s vision at risk. The current work aims to report a case of corrective surgery for stromal abscess in a mare with the administration of intraoperative intrastromal fluconazole, in orderto corroborate the effectiveness of the technique.Case: A 9-year-old mare was evaluated, with the complaint that her right eye was closed and “yellowish” and that she hadalready been treated with intramuscular injectable anti-inflammatory drugs based on flunexin meglumine (Banamine® -50 mg) for 15 days, referring to a possible ulcer in the right eye. Ophthalmic screening resulted in a negative direct reflexand no threat response in the right eye. Examination of the conjunctiva showed congestion and chemosis. Examination ofthe cornea of the right eye was negative for Fluorescein and Green Lissamine tests, and opacity and corneal neovascularization were noted. The final diagnosis was a corneal abscess of probable fungal origin secondary to a keratomycosis. Afterthe consultation, complementary blood and biochemical tests were performed, which showed normal results for the speciesin question, and treatment was started with eye drops based on atropine 1% (Fagra® - 20 mL), ciprofloxacin antimicrobialeye drops (Ciprovet Colirio® - 5 mL), and antifungal eye drops based on ketoconazole...

O hemangiossarcoma é uma neoplasia maligna e sua apresentação corneal é rara em cães. Relata-se um caso de hemangiossarcoma corneal primário, em uma fêmea canina, sem raça definida, de 20kg, nove anos de idade e com histórico de crescimento progressivo de massa em bulbo ocular direito há dois meses. Ao exame oftálmico do olho direito, foram observados blefarospasmo, hiperemia conjuntival moderada e presença de nódulo avermelhado, irregular em região dorsal de córnea direita, ocupando cerca de 60% dela. A ultrassonografia ocular foi realizada, e constatou-se que a neoplasia acometia apenas a córnea. Por meio do exame citológico, foi diagnosticada neoplasia mesenquimal maligna. O paciente foi submetido à ceratectomia seguida de flap de terceira pálpebra. Encaminhou-se o material excisado para análise histopatológica, e foi diagnosticado hemangiossarcoma. Após 15 dias, o flap de terceira pálpebra foi retirado, e, ao exame oftálmico, notou-se a recidiva da neoplasia, que recobria toda a córnea e parte da conjuntiva bulbar, procedendo-se à enucleação. O paciente foi submetido à ultrassonografia abdominal e à radiografia torácica sem nenhuma alteração evidente, o que caracterizou o caráter primário da afecção. Após dois anos do procedimento cirúrgico, o paciente encontra-se bem clinicamente, sem qualquer sinal de recidiva ou metástase. Apesar da exérese cirúrgica da neoplasia com margens limpas, em casos de hemangiossarcoma com comportamento agressivo, a enucleação deve ser considerada uma opção viável para um protocolo terapêutico de sucesso e melhor prognóstico do paciente.(AU)


Hemangiosarcoma is a malignant neoplasm and its corneal presentation is uncommon in the dog. The present work reports a case of primary corneal hemangiosarcoma on a mongrel female dog, 20kg, nine years old with a 2 month history of a mass with progressive growth in the right eye. The ophthalmic examination of the right eye showed blepharospasm, moderated conjunctival hyperemia and the presence of a reddish irregular nodule on the dorsal region of the cornea, occupying approximately 60% of the cornea. The ocular ultrasound revealed that the neoplasm affected only the cornea and the cytological examination diagnosed a malignant mesenchymal neoplasm. The patient was submitted to keratectomy followed by a third eyelid flap. The excised material was sent for histopathological analysis that diagnosed hemangiosarcoma. Fifteen days after surgery the third eyelid flap was removed and the ophthalmic examination revealed recurrence of the tumor, with the mass occupying the entire cornea and part of the bulbar conjunctiva. The patient was submitted to enucleation. No alterations were observed on the abdominal ultrasound and thoracic radiography, showing the primary characteristics of the disease. Two years after surgery the patient is clinically healthy, without any signs of recurrence or metastasis. Despite the surgical excision of the tumor with free margins, in cases of hemangiosarcoma with aggressive behavior, the enucleation should be considered as a viable option for a successfull therapeutic protocol and better prognosis of the patient.(AU)

Background: Intrastromal corneal cysts are uncommon lesions caused by the implantation of corneal epithelial cells in the stroma, and their subsequent intrastromal proliferation, which has often been secondary to trauma. Lamellar keratectomy has been the chosen treatment and diagnosis has been confi rmed by histopathology. In this report, we describe a case of corneal epithelial inclusion cyst in a dog that was successfully treated with lamellar keratectomy.Case: A 10 year old Yorkshire Terrier dog was referred to the Ophthalmology Section of the Veterinary Clinics Hospital of the Federal University of Rio Grande do Sul (UFRGS), presenting an abnormal appearance in the left cornea. The ophthalmic examination revealed a white and elevated mass, measuring approximately 3 mm in the left cornea. Thus, a superficial keratectomy was performed by utilizing an angled ophthalmic disc knife, under general anesthesia, and an operating microscope. In addition, a third eyelid fl ap was performed to protect the cornea. The postoperative treatment involved broad-spectrum antibiotic containing tobramycin 0.3%, and a non-steroidal anti-inflammatory solution of sodium diclofenac 0.1%, administered six times a day for two weeks. In addition, atropine sulphate 1% was applied once a day for five days. After three weeks of follow-up, the third eyelid flap was removed, and there was no evidence of...(AU)

A case of a two-year-old male Pinscher with a history of discomfort in the right eye was reported. The left eye had been enucleated by the referring veterinarian due to the same symptom with unsuccessful clinical treatment. The Schirmer tear test value was elevated and a decreased intraocular pressure was observed by applanation tonometry. Biomicroscopy revealed profuse corneal edema and keratoconus and fluorescein staining was negative. Gonioscopy and ophthalmoscopy did not provide any relevant data due to the corneal alterations. Bullous keratopathy was diagnosed. Surgery was performed in two steps: 1) superficial keratectomy and 360º conjunctival flap, and 2) superficial keratectomy to restore corneal transparency. Thirty days after the second superficial keratectomy, the third eyelid flap was removed. Conjunctivalization of the upper nasal quadrant of the cornea was observed. The axial portion of the cornea was transparent and vision was restored.(AU)


Relata-se o caso ocorrido em um cão, da raça Pinscher, com dois anos de idade e histórico de desconforto no olho direito. O olho esquerdo havia sido enucleado por outro profissional, por apresentar os mesmos sinais, cujo tratamento clínico instituído não lograra êxito. O valor do teste da lágrima de Schirmer encontrava-se aumentado e identificou-se diminuição da pressão intraocular à tonometria de aplanação. Observaram-se, à biomicroscopia, edema corneal profuso e ceratocone, e o teste da fluoresceína foi negativo. Gonioscopia e oftalmoscopia não lograram fornecer dados relevantes dadas as condições da córnea. Diagnosticou-se ceratite bolhosa. Optou-se pelo tratamento cirúrgico, que fora realizado em duas etapas: 1- ceratectomia superficial e "flap" conjuntival de 360º; 2- ceratectomia superficial para devolver transparência à córnea. Transcorridos 30 dias da segunda ceratectomia superficial, o "flap" de terceira pálpebra foi desfeito. Observou-se conjuntivalização do quadrante nasal superior da córnea, córnea clara no eixo visual e retorno da visão.(AU)

Squamous cell carcinoma (SCC) is a neoplastic disease of the squamous epithelial cells that has been rarely described in the literature. This neoplasm affects the eyelid, conjunctiva and third eyelid, as well as the cornea. Corneal SCC is a neoplastic lesion characterized by a pink, typically irregular mass protruding from the epithelial surface of the cornea. Canine corneal SCC has been associated with chronic keratoconjunctivitis sicca, or keratitis secondary to exophthalmia and is common in humans, horses and cows. The treatment is surgical with excision of the lesion of the ocular surface. This paper reported a study of a dog with corneal SCC, which was successfully treated with a superficial lamellar keratectomy excision combined with cryosurgery.

Foi atendido um cão, fêmea, sem raça definida, de 8 anos de idade, com histórico de um tecido avermelhado na superfície do olho esquerdo (OE) com evolução de aproximadamente 1 mês. Ao exame oftálmico não foram observadas outras alterações oculares, exceto a presença da massa, ocupando grande parte da superfície corneana e discreta secreção mucosa. Foi instituída terapia tópica à base de dexametasona sem melhora clínica. Com base nos achados, a suspeita diagnóstica foi de neoplasia corneana sendo realizada ceratectomia lamelar superficial. No pós-operatório, observou-se vascularização leve e opacidade corneana, com visão preservada. O exame histopatológico confirmou o diagnóstico de neoplasia vascular benigna compatível com hemangioma. Houve recidiva após 12 meses e nova cirurgia foi realizada com sucesso. O hemangioma primário de córnea é uma neoplasia rara, e deve ser considerado como diagnóstico diferencial de alterações corneanas não responsivas a tratamento clínico. O caso está sendo acompanhado e não houve recidiva até o presente momento.AU


An 8-year-old dog, female, mixed breed, was presented for evaluation of a reddish tissue on the surface of the left eye (OS) that had been growing for about 1 month. Ophthalmic examination showed no ocular abnormalities, except for the presence of the mass, affecting much of the corneal surface and discrete mucous discharge. Was instituted topical dexamethasone therapy without clinical improvement. . Based on the clinical findings, a diagnosis of corneal neoplasia was suspected. Superficial lamellar keratectomy was performed. Postoperatively, mild corneal opacity and vascularization were noticed, with no visual impairment. Histopathological examination confirmed the diagnosis of benign vascular neoplasm compatible with hemangioma. The neoplasia recurred after 12 months and another surgery was successfully performed. Primary hemangioma of the cornea is a rare neoplasm, and should be considered as differential corneal alterations do not respond to medical treatment. The case is being followed and there was no recurrence to date.AU

Resumo

A six-year old Simmental cow was referred to the Veterinary Hospital in Cuiaba, Brazil, with an ocular tumor involving the cornea and conjunctiva. The animal was submitted to regional anesthesia after which superficial keratectomy and conjunctival incision were performed. Third palpebral flap and adequate post-surgical therapy were employed. By the 12th post operative day the fluorescein dye test was negative. The tumor was examined by histopathology and was diagnosed as ocular squamous cells carcinoma. Relapse was not observed up to 18 months after the surgery.
