Squamous cell carcinoma (SCC) is a form of neoplasm that origins from the epithelial surface of many organs. Ocular occurrence in small animals is rare, especially in the central cornea without the involvement of limbus or conjunctiva. In the current case, a 10-year-old, spayed female Shih-Tzu was presented with a central corneal mass. Through an ophthalmic examination the sign of corneal scarring around the mass was found. Pink fleshy lesion that protruded outward was removed through superficial keratectomy. The mass with the size of $8.5{\times}6.5$ millimeter was histopathologically diagnosed as corneal SCC infiltrating not only the epithelium, but also the superficial corneal stroma with surrounding superficial lymphoplasmacytic and neutrophilic chronic keratitis. Also, the adjacent, non-affected corneal epithelium was markedly hyperplastic and keratinized; the adjacent stroma was moderately vascularized and fibrotic. The pulse-dose therapy using 1% topical 5-flourouracil were applied for five cycles. The tumor has not recurred through nine months of follow-up time.

Background: Rocuronium bromide has been evaluated as a mydriatic agent in birds, but the species applied were limited and the dose and effect were variable. Objective: This study aims to evaluate the efficacy of topical rocuronium bromide as mydriatics in 4 species according to horizontal palpebral fissure length: Feral pigeon (Columba livia), Common kestrel (Falco tinnunculus), Northern boobook (Ninox japonica), and Eurasian eagle owl (Bubo bubo). Methods: A total of 32 birds (8 for each species) were included as pre-releasing examination. Rocuronium bromide was instilled in one randomly selected eye of each bird based on palpebral fissure length criteria (0.5 mg/50 µL for pigeons, 1 mg/100 µL for kestrels and boobook owls, and 2 mg/200 µL for eagle owls). The contralateral eye was used as control and treated with normal saline. After instillation of the drug, pupil diameter, pupillary light reflex, intraocular pressure, heart rate, and respiratory rate were evaluated at 10 min intervals up to 180 min and at 30 min intervals up to 360 min. Results: Statistically significant mydriasis was obtained in all birds (p < 0.001). However, in boobook and eagle owls, marked mydriasis persisted until 360 min. Side effects including corneal erosion and lower eyelid paralysis were common, which was observed in 26/32 birds. Blepharospasm was also noted during this study. No systemic adverse signs were observed. Conclusions: Rocuronium bromide could be a good mydriatics option for 4 species of birds, however, further studies are needed to find lowest effective dose to reduce drug-related side effects.

A 2-year-old miniature poodle dog was referred to Seoul Animal Clinic for assessment of traumatic ocular lesion by cat claw. Corneal perforation accompanied by hyphema following iridal laceration was observed in the left eye. Topical antibiotics, mydriatics and systemic antibiotics/steroids were applied to treat severe uveitis with miosis and fibrinous exudate. Although lenticular lesion was explored after mydriasis, it was obscured by severe corneal edema around corneal perforation. Despite aggressive treatments, the uveitis became more serious in the next day. To prevent septic implantation syndrome from anterior lens capsule disruption, phacoemulsification surgery was performed. The anterior lens capsule disruption was detected during continuous curvilinear capsulorhexis. The left eye remained the vision with mild posterior capsule opacification and intermittent conjunctival hyperemia during seven-month follow-up.

A two-year-old, spayed female, Bichon Frise, was referred for severe corneal edema and corneal ulcer in the left eye (OS). The cornea had gradually swelled over one week after phacoemulsification performed a month prior, and that was refractory to 5% sodium chloride eye drop instillation or temporary partial tarsorrhaphy. A complete ophthalmic examination was performed. Severe corneal edema with intrastromal bullae and moderate anterior chamber flare was found on slit-lamp biomicroscopy in the OS, which obstructed the fundus examination. Corneal thickness was measured using high-resolution ultrasound biomicroscopy. The thickness of the OS cornea was 2.74 mm. The "letter-box" conjunctival flap was planned. Dorsal and ventral superficial keratectomy followed by a hood conjunctival flap was performed. Topical and systemic antibiotics and 5% sodium chloride eye drops were prescribed. Decreased corneal thickness was observed at one week, two weeks, and two months postoperatively (1.53 mm, 1.32 mm, and 0.92 mm, respectively). There were no postoperative complications, such as ocular discomfort or recurrent corneal ulcers. The "letter-box" conjunctival flap, a type of superficial keratectomy and conjunctival advancement hood flap, effectively relieved the severe irreversible corneal edema. This could be a simple but effective surgical intervention for patients with endothelial cell damage especially after phacoemulsification.

The purpose of this study was to determine clinical features of canine episcleritis and outcomes of therapy in Korea. The medical records of dogs with episcleritis presented at the Veterinary Medical Teaching Hospital of Seoul National University from January 2006 to December 2007 were reviewed. Episcleritis was diagnosed in 17 eyes of 12 dogs. The most frequently affected breed was Shih Tzu (n = 6). The median affected age was 5 years with a range from 3 years to 12 years. Simple episcleritis was identified in 8 dogs, nodular granulomatous episcleritis (NGE) in 3 dogs, and secondary episcleritis caused by panophthalmitis in a dog. The combination immunosuppressive therapy of topical corticosteroids, topical cyclosporine A, and intralesional injection of triamcinolone (4 mg) and gentamicin (4 mg) was performed. Most of the patients with episcleritis were resolved within 30 days following the therapy. Surgical excision was performed in 1 NGE case which was not responded to the medical therapy. Recurrence was observed in 4 dogs between 5 and 8 months after the first visit. It is considered that strong immunosuppressive therapy and periodic ocular examination are needed to control episcleritis.

Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease, often underdiagnosed or misdiagnosed in children. We describe the case of a 12-year-old boy who presented to Severance Hospital with a 1-month history of bilateral conjunctival injection. He was first evaluated by an Ophthalmologist in another hospital and diagnosed with panuveitis. Laboratory tests indicated renal failure, and a renal biopsy confirmed the diagnosis of acute tubulointerstitial nephritis. An extensive exclusion of all possible causes allowed a diagnosis of TINU syndrome. The patient was treated with a systemic corticosteroid (initially prednisolone, 2 mg/kg and later deflazacort 1 mg/kg) and topical steroid drops for 1 month. Azathioprine was later added to the treatment regimen and the systemic steroid was slowly tapered. The final outcome of renal-ocular disease was favorable in the patient. However, long-term follow-up is necessary to properly manage frequent relapses and incomplete renal recovery. TINU should be considered as a differential diagnosis in children with uveitis or acute renal failure.

Horner's syndrome is a group of clinical signs that results from interference with the sympathetic innervation of the globe and adnexa. Three dogs were presented with unilateral ptosis, miosis, enophthalmos and protrusion of the third eyelid. There were no other clinical signs on physical and neurological examination. On ophthalmic examination, the symptomatic eyes were diagnosed as Horner's syndrome. In order to localize the site of the lesion, pharmacological testing was performed through assessment of ocular response to the topical administration of 10% phenylephrine and clinical signs were resolved within 20 minutes. The pharmacological testing suggested that the deficit could be at the postganglionic neuron. Total resolution of clinical signs was observed within 6 months after their initial appearance without any treatment.

베체트병은 전신적 혈관염으로 여러 장기에 걸쳐 나타날 수 있으며, 현재로선 확진을 위한 검사 방법이 없으므로 병의 진단은 임상적 증상에 기초하여 내려진다. 구강 및 외음부의 재발성 궤양, 피부 병소, 안구 병소, 및 이상초과민검사(pathergy test)에 대한 반응을 기초로 진단을 내리며, 이 외에도 위장관과 중추신경계에 증상이 나타날 수 있다. 이 중 재발성 구강 궤양은 대부분의 베체트병 환자에서 나타나며, 많은 경우 베체트병의 첫번째 임상 증상으로 발현되기 때문에 치과 영역은 베체트병의 조기 진단에 있어서 중요한 위치에 있다. 본 증례에서 6세 여환은 반복되어 나타나는 재발성 구강 궤양으로 인한 동통 및 섭식 장애를 주소로 본원 소아치과에 내원하였다. 문진 및 병력 채취, 그리고 임상 검사를 통해 치과 영역에서 베체트병을 조기 진단할 수 있었고, 추후 환자는 소아과, 피부과, 소화기내과, 안과와의 협의 진료 하에 베체트병으로 확진되었다. 치과에선 환자의 동통을 완화시키고 섭식을 돕기 위해 도포마취제를 처방하였으며, 추후 베체트병의 확진 하에 그에 따른 적절한 의과적 치료를 시행할 수 있었기에 보고하는 바이다.
