A 14-year-old neutered-male Shih-Tzu was referred for glaucoma and hyphema accompanied by systemic hypertension. After topical corticosteroid and antiglaucoma medications, the left eye (OS) progressed phthisically, but ocular hypertension redevelop one-year-and-seven-months later. Suspected limbal melanoma developed in peripheral cornea/limbal sclera with heavily pigmented cornea OS. Ultrasound biomicroscopy and ocular ultrasonography differentiated ciliary body origin-heterogeneous mass from limbal mass. Persistent hyphema and pigmented cornea might obscure intraocular lesion and advanced diagnostic methods played a crucial role. Unlike the generally benign limbal melanoma, aggressive treatment was recommended for uveal tumor. Histopathology of enucleated OS confirmed malignant uveal melanoma with chronic hypertensive vasculopathy.

A 3-month-old, female Persian cat was presented with sclera mass. The mass was detected after cat's squeals during the playing with a dog before 2 days. On ophthalmic examination, a $2{\times}5mm$ dark purple colored raised mass was observed 1 mm behind the limbus in the right eye. Anterior chamber was filled with blood and epithelial defect was detected at 2 o'clock in the right central cornea. After general anesthesia, resection of the protruded iris was performed with iris scissors and bipolar cautery. Ruptured sclera and conjunctiva were closed with simple interrupted and simple continuous suture, respectively. Also, irrigation and aspiration (I/A) of the anterior chamber was performed to remove blood clot with bimanual I/A handpiece in the right eye. Four months after the surgery, the right eye was recovered completely and menace response was positive in spite of the retinal lesions.

Pharmacological ablation of the ciliary body by intravitreal injection of a cytotoxic dose of gentamicin was utilized for the treatment of absolute glaucoma in 13 dogs. Complications of this procedure were hyphema(2), corneal opacity(2), iris bombe(1), cataract(1) and chronic inflammation(1). Injection time was one time in 10 dogs, two times in 2 dogs and 3 times in a dog. Intravitreal injection of gentamicin was thought as a economic salvage procedure and has resulted in successful lowering of intraocular pressure.

Orbital injuries are common with facial trauma. Direct injuries to the globe are not rare but it can result in complications such as chemosis, subconjunctival hemorrhage and hyphema. Periorbital trauma or injuries to the extraocular muscles and blow-out fracture may result in lid edema, ecchymosis & ptosis and diplopia or limitation of ocular motion respectively. Indirect injuries to the optic nerve come up without any injuries but its complication is irreversible and severe such as loss of vision. The aim of this study is to review the literature on blindness or ptosis following facial trauma and present the cases of blindness after facial trauma and ptosis after mandibular fracture without specific clinical findings.

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 14-year-old, male Shih-tzu was presented with glaucoma in the left eye. Menace response was negative in the left eye. On ophthalmic examination, exotropia, buphthalmos, bulging of upper lateral globe and episcleral injection was detected in the left eye. Also, there was corneal edema, corneal pigmentation and hyphema in the left eye. The pupil was difficult to observe due to corneal lesions in the left eye. On ultrasonographic examination, an amorphous large mass protruding from the region of the optic disc into the vitreous was observed in the left eye. Enucleation was performed in the left eye. Histologically, the left intraocular mass was diagnosed as glioma. Immunohistochemically, the neoplastic cells were positive to glial fibrillary acidic protein.

This experiment was carried out to investigate the optimal dose of intravitreal gentamicin that decreases intraocular pressure effectively and minimizes complications in dog. After inhalation anesthesia, gentamicin was injected intravitreally into the left eyes at doses of 10, 15 and 20 mg with 1 mg dexamethasone, respectively. Sterilized isotonic saline and dexamethasone mixture into the right eyes for control. Six dogs were used in each group. Intraocular pressures were measured using applanation tonometer(Mentore, Tono-Pen) until 5 months after injection of gentamicin. Ocular examinations were performed using direct ophthalmoscopy. The ocular volumes of both eyes were measured. Intraocular pressures of eyes injected with 10. 15 and 20 mg of gentamicin were decreased significantly compared with control eyes. Severe corneal opacity and neovascularization occurred in 20 mg treated group. Intraocular hemorrhage was observed in 3 dogs of 20 mg treated group. Ocular volume was significantly decreased(p <0.05) in 20 mg treated group, compared with 10 and 15 mg treated group. It is considered that intravitreal gentamicin injection at dose of 10 mg or 15 mg decrease intraocular pressure effectively and minimize complications such as corneal opacity, hyphema and phthisis bulbus.

Purpose: Blunt trauma can cause a wide range of ocular injuries. This study was performed to describe the prevalence of severe intraocular injuries (SIOI) and their correlation with the severity of blunt orbital trauma. Methods: We retrospectively analyzed 117 eyes of 107 patients with orbital wall fractures who visited the emergency room at Konyang University Hospital from July 2006 to June 2008. Clinical features such as age, sex, causes of injury, revised trauma score (RTS), type of orbital wall fractures were recorded. The patients were divided into two groups: blowout fracture with severe intraocular injuries (SIOI) and blowout fracture without SIOI. We compared the clinical and the injury-related characteristics between two groups and analyzed the SIOS-related factors. Results: Among the 107 patients (117 eyes) with blowout fractures, 29 (27.1%) patients with 32 eyes (25.6%) had complicated severe intraocular injuries. Retrobulbar hemorrhage (14.5%), hyphema (13.7%), traumatic optic nerve injury (4.3%), and sustained loss of visual acuity (4.3%) were the most common SIOI disorders. A logistic regression analysis revealed that loss of visual acuity (odds ratio = 4.75) and eyeball motility disorder (odds ratio=7.61) were significantly associated with SIOS. Conclusion: We suggest that blowout fracture patients with loss of visual acuity or eyeball motility disorder are mostly likely to have severe intraocular injuries, so they need an ophthalmologic evaluation immediately.

6년령 중성화 수컷의 말티즈가 서울대학교 부속 동물병원에 내원하였다. 안검사 상 우안의 전방출혈 및 안방수 흐림이 확인되었으며 포도막염에 대한 치료가 진행되었다. 4개월 후 우안 홍채의 등쪽 측면의 전방변위가 확인되었으며 안초음파 검사상 모양체 유래의 종괴로 잠정 진단되었다. 흉부 및 복부 영상검사에서는 종양의 전이소견이 발견되지 않았다. 이후 지속적인 포도막염과 종괴의 종대로 인해 우안의 안구 적출을 실시하였다. 조직병리학적 검사에서 우안의 종괴는 만성적인 출혈을 동반한 전포도막 흑색세포종으로 확진되었다. 본 증례와 같이 안내 종양 환자에서 비수술적인 처치로 눈의 지속적인 출혈이나 염증이 호전되지 않는 경우, 안구적출을 통한 적절한 안내 종양의 제거가 고려되어야 한다.

녹내장 누공수술의 대표적 수술인 섬유주절제술의 주된 실패요인인 여과포의 섬유화를 막아 수술성공율을 향상시키기 위해 항대사 물질인 Mitomycin C를 수술실패 위험이 높은 녹내장 환자 20명 25안을 대상으로 섬유주절제술중에 사용하여 섬유주절제술의 보조제로서의 Mitomycin C의 효과를 알아보았다. 전체 대상안의 수술전 평균 안압은 $38.6{\pm}6.6mmHg$였으며 수술 후 최종 평균안압은 $11.7{\pm}3.8mmHg$로 26.9mmHg의 안압감소를 나타내었다. 수술 성공율은 40세 이하의 원발광우각녹내장에서는 8안중 7안 (88%), 포도막염에 의한 속발 녹내장에서는 6안중 5안(83%), 신생혈관녹내장에서는 5안중 4안(80%)에서 성공하였고 유년녹내장과 과거 수술 기왕력이 있는 녹내장 및 무수정체녹내장에서는 6안 모두 (100%)에서 성공함으로서 전체적으로는 25안중 22안에서 성공하여 88%의 성공율을 나타내었다. 수술 후 시력 변화는 25안중 24안(96%)에서 수술전 시력에 비해 변함이 없거나 다소 호전되었으며 1안(4%)에서 시력 소실을 보였다. 술후 합병증은 전방출혈이 5안(20%), 얕은 전방이 4안(16%), 저안압증이 4안(16%), 점상각막염이 3안(12%), 결막봉합파열이 2안(8%), 낭포화된 여과포가 1안(4%), 맥락막 박리 1안(4%)에서 발생하였다. 결론적으로 섬유주절제술에서 Mitomycin C의 부가적 사용은 수술 실패 위험이 높은 녹내장에서 효과적이고 비교적 안전하게 사용할 수 있으나 장기간 경과 관찰을 통하여 안전하고 효과적인 사용법에 대한 다양한 연구가 필요할 것으로 사료된다.
