A 15-year-old castrated male Persian (Case 1), an 1.5-year-old castrated male Bengal (Case 2), and an 1.5-year-old spayed female Russian Blue (Case 3) cats were presented with iris-color change and suspicious anterior chamber mass. Complete ophthalmic examination revealed a vascularized or blood tinted mass filling with anterior chamber accompanied by rubeosis iridis, dyscoria, keratic precipitates, and severe aqueous flare. Ocular ultrasonography showed an iridociliary mass with blood flow signal in Case 1. Abdominal ultrasonography also revealed suspicious metastatic involvements of liver and spleen in this cat. Case 2 and 3 were suspected of being infected with feline infectious peritonitis. Topical antibiotic/steroid combinations were prescribed to control the uveitis in all 3 cases, although enucleation was initially considered for palliative pain management in Case 1. Anterior chamber mass had almost completely disappeared after topical medications and uveitis has been successfully managed, remaining in sight, even though ocular hypertension developed 1 month later in Case 1.

2009년 1월 6일경 어청도~고군산군도 사이에서 채낚기로 어획되어 군산수협 위판장에서 입수한 홍가자미의 피부 유두종을 병리조직학적으로 검사한 결과 저서성 어류에 발생되고 있는 상피성 유두종으로 종양의 내부는 특징적인 x-cell로 구성되어 있었다. 그러나 x-cell의 핵내의 특징인 대형의 핵인은 시료채취 후의 자가 분해에 의한 탓인지 관찰할 수 없었다.

A 10-year-9-month-old spayed female Shih Tzu was presented with ocular discharge and corneal opacity to Veterinary Medical Teaching Hospital of Seoul National University. Complete ophthalmic examination revealed bilateral keratoconjunctivitis sicca accompanied by the severe corneal neovascularization and edema in the right eye (OD). Ultrasound biomicroscopy incidentally showed an iridociliary mass located at 6~7 o'clock in the OD. No evidence of metastasis was observed on thoracic and abdominal radiography. Enucleation was selected and performed on the OD, considering the risk of metastasis or recurrence. Non-invasive and pigmented iridociliary adenoma was confirmed on histopathological evaluation.

안와 림프종의 치료에 가장 효과적인 치료법인 방사선 치료는 안구 질환의 증가로 인해 계속 늘어나는 추세이다. 항암화학요법과 치료 기술의 비약적인 발전으로 치료 및 예후가 좋아지고는 있지만 백내장, 안구건조, 망막병증 등의 부작용이 발생되고 있다. 이에 본 연구에서는 안와 림프종의 방사선치료 시 백내장 발생의 방어수단으로써 Lens Shielding Device(이하 LSD)를 고안 제작하였고 이의 제작방법과 방사선 차폐 정도에 대해 알아보았다. 안구 표면에 해당하는 깊이에서 TLD의 측정결과는 3개의 평균값이 5.7%로 나타났고 관심부위인 수정체의 위치에서는 TLD 4.2%, markus chamber 5.1%의 선량값을 나타내었다. 본 연구에서 안와에 발생한 림프종의 방사선 치료로 인한 부작용을 예방하기 위해 제작한 LSD는 치료 중 조사받게 되는 총 30Gy의 선량 중에서 5%에 해당하는 약 1.5Gy의 방사선량만이 수정체와 각막에 영향을 미치는 것으로 확인되어 백내장의 역치선량인 2Gy와 임상적으로 백내장이 발생된다고 보고된 5Gy보다 적은 선량이 조사됨을 알 수 있었다. 방사선 치료 시 발생할 수 있는 여러 부작용의 예방에 유용한 기구임을 확인하였고 환자의 안구와 일치되도록 개인별로 제작하여 착용 시 이물감에 의한 불편을 줄일 수 있을 뿐만 아니라 치료 시 고정 또한 매우 용이함을 검증하였다.

Objective : The aims of this study were to investigate the quantitative relationship between pituitary macroadenoma size and degree of visual impairment, and assess visual improvement after surgical resection of the tumor. Methods : The medical records of patients with pituitary adenoma, who had undergone trans-sphenoidal adenectomy between January 2009 and January 2011, were reviewed. Patients underwent an ocular examination and brain MRI before and after surgery. The visual impairment score (VIS) was derived by combining the scores of best-corrected visual acuity and visual field. The relationship between VIS and tumor size/tumor type/position of the optic chiasm was assessed. Results : Seventy-eight patients were included (41 male, 37 female). Thirty-two (41%) patients experienced blurred vision or visual field defect as an initial symptom. Receiver operating characteristic curve analysis showed that tumors <2.2 cm tended to cause minimal or no visual impairment. Statistical analysis showed that 1) poor preoperative vision is related to tumor size, displacement of the optic chiasm in the sagittal view on MRI and optic atrophy, and 2) poorer visual prognosis is associated with greater preoperative VIS. In multivariate analysis the only factor significantly related to VIS improvement was increasing pituitary adenoma size, which predicted decreased improvement. Conclusion : Results from this study show that pituitary adenomas larger than 2 cm cause defects in vision while adenomas 2 cm or smaller do not cause significant visual impairment. Patients with a large macroadenoma or giant adenoma should undergo surgical resection as soon as possible to prevent permanent visual loss.

원발성 안구 흑색종은 20세 이상의 성인에서 가장 많이 발생되는 안주의 악성종양이지만 한국에서의 발생빈도는 그리 흔하지 않은 것으로 되어 있다. 안구 흑색종의 치료전에는 문진, 이학적검사, 기본적인 혈액상검사와, 특히 간, 폐, 골에 세심한 주의를 하여야 하며, 그래서 흉부 X-선과 LDH, SGPT, Transpeptidase를 포함한 간기능 검사 등을 시행하여야 하고 만약 임상적으로 증상이 있거나 위의 검사상 비정상적인 소견을 보일 매에는 전신뼈 스캔, 간-지 라 스캔을 시행하여야 한다. 일반적으로 악성 흑색종은 방사선 치료에 대해 치료효과가 나쁜 것으로 알려져 있지만 때로는 총 종양조사선량 $7,000\~8,000 cG/8\~9$주로 매우 빠른 종괴의 감소를 보여 주기도 한다. 그리하여 저자등은 외부방사선조사로 빠른 치료반응을 보인 원발성 안주 흑색종의 치료와 문헌고찰을 보고하는 바이다.

This report aims to describe a case of tumor-like lymphoplasmacytic conjunctivitis in a 7-year-old spayed-female Pomeranian. On complete ophthalmic examination, a mass with papillary projections was noted on the bulbar surface of the right third eyelid. Debulking of the mass was performed while preserving as much of the third eyelid as possible. On the histopathological examination, the mass was diagnosed as lymphoplasmacytic conjunctivitis with mild epithelial hyperplasia. Although a slight regrowth of the mass was noted 3 weeks after surgery, intralesional injection of triamcinolone acetonide led to its disappearance. There was no further recurrence after 5 months.

Pituitary apoplexy resulting from hemorrhage or necrosis of a pituitary tumor with subsequent compression of the optic nerves and cavernous sinuses is a life-threatening condition. The diagnosis is made clinically by the sudden onset of headache, meningismus, visual impairment, and ocular abnormalities, Modern surgical techniques seem to have reduced morbidity. Nevertheless, it is evident that not every patient requires surgical decompression after pituitary apoplexy because of spontaneous resolution after hormonal replacement therapy. We report an 84-year-old man who had pituitary apoplexy presenting with headache, ptosis and eyelid swelling. A good result has been achieved with immediate replacement of steroid.

Behçet's disease (BD) is a systemic immunological disorder characterized by recurrent mucosal ulcerative lesions including oral and genital ulcerations in association with skin and ocular involvements. BD also can involve the gastrointestinal tract. Gastrointestinal involvement of BD is one of the major causes of morbidity and mortality for this disease. However, clinical data are quite limited because of the rarity of intestinal BD. Therefore, the management of intestinal BD is heavily dependent on expert opinions and standardized medical treatments of intestinal BD are yet to be established. In this brief review, the authors summarized the currently available medical treatments such as 5-aminosalicylic acids, corticosteroids, immuno-modulators, and anti-TNF agents. Moreover, we sought to suggest a treatment algorithm for intestinal BD based on the recently published and updated data.
