Bilateral convergent strabismus with exophthalmus(BCSE) is an eye disorder affecting many cattle breeds worldwide. BCSE is the most common in cattle at various types of strabismus. Divergent strabismus is of relatively low incidence than convergent strabismus. This report is the to shown a case of convergent and divergent strabismus with unilateral in the exophthalmus in a heifer Holstein cow. A female Holstein calf born with congenital progressive divergent strabismus in right eye and convergent strabismus in left eye was tested. Ocular and blood examination, and activity were checked from the first week, 8 month, and 16 month after birth. The ocular examination includes general inspection, fixation reflex and menace response. The general inspection is checking the degree of deviation of both eyes from the normal visual axis, which was determined by the amount of sclera permanently visible in the temporal corner of the eye. The stage is divided into 4 stages depending on the degree of deviation. The right eye shown in stage 4 continues after birth and the left eye shown stage 2, stage 3 and stage 4 at 1 week, 8 month and 16 month after birth, respectively. In fixation reflex and Menace response, both eye balls showed a normal response at 1 week, 8 month and 16 month after birth. Blood count and serum chemistry test were performed, but a specific factor was not detected outside the reference range.

Lymphangioma is a rare benign developmental vascular tumor that may be found in orbit, skull and elsewhere in head and neck. Few cases of extension of this benign but insidious tumor posteriorly out of the bony orbital cavity have been reported. The patient was 40-year-old man complaining of proptosis of right eye for one month. Physical examination revealed severe right exophthalmus, impairment of eyeball movement in all directions. Visual acuity was much impaired and he could percept only light with right eye. CT and MRI scans showed intraconal and extraconal involvement of ill-defined, heterogenous mass with extension of the tumor posteriorly beyond the orbital cavity involving right frontal and temporal lobe, skull and subcutaneous tissue. The tumor was subtotally removed via orbito-frontal approach without damaging vital neural and orbital component. Then, orbital roof reconstruction and cranioplasty were done with resin. Successful surgical removal of lymphangioma is very difficult due to its severe infiltration to surrounding tissue and tendency to bleed during debulking. We report a rare case of orbital cavernous lymphangioma with intracranial extension treated with surgical decompression, with review of literatures.

Surgery and radiotherapy are mainly used for plasma cell neoplasm which constitutes about $1{\sim}2%$ of human malignancy. The authors carried out Fractionated Stereotactic Radiotherapy[FSRT] on the residual tumor after the subtotal removal of Intracranial plasmacytoma. A huge mass lesion was observed on MRI [magnetic resonance image] in the left anterior and middle cranial fossa of a 63-year-old man with left exophthalmus which lasted for a month, and was suspected as a meningioma with strong contrast enhancement. Extramedullary plasmacytoma was diagnosed on histopathological examination. After the surgery, FSRT was also carried out on the residual tumor which invaded the skull base. One-year follow up after FSRT showed contrast enhancement only in the left sphenoid bone on MRI, which indicated significant decrease in the size of the tumor without any abnormal neurologic deficits. We treated intracranial plasmacytoma which invaded left anterior and middle cranial fossa and surrounded cavernous sinus without cranial nerve deficit through subtotal tumor removal and FSRT.

The high mortality of cultured turbot, Scophthalmus maximus was occurred from Gochang in June, 2003. Infect fish with iridovirus showed a lower feed intake and lethargic. These fish exhibited pale body color, extended abdominal and exophthalmus. Histopathological studies showed basophilic enlarged cells from kidney, spleen, gill, heart, muscle, stomach, intestine, liver and pancreas of these fish. In PCR amplification with red sea bream iridovirus (RSIV) specific primer set of a DNA fragment of 286 bp was obtained from infect turbot with the virus. The strain showed the high homologies with RSIV, LBIV (largemouth bass iridovirus), GSIV (giant seaperch iridovirus) and SBIV (sea bass iridovirus).

In Feb., 1990 an epizootic disease to masu salmon fry, Oncorhynchus masou cultured at the hatchery of rainbow trout in Samchok, Kwangwon-do have broken out and induced high mortality over 70%. Externally, the diseased fish showed dark discoloration, abdominal distension with ascites, slight exophthalmus and fecal casts. Internally, the gill and the liver of diseased fish were edematous and pale, and the stomach of moribund fish contained the milkish fluid. Microscopically there was extensive necrosis of the hematopoietic tissue in kidney and spleen, and scattered necrosis of pancreas, liver and lateral muscle. Especially, the necrosis of lamina propria, muscle layer and tela submucosa in the digestive tract known as the typical signs associated with infectious hematopoietic necrosis virus was seen clearly.

From August to October of 1991, a bacterial disease occurred in cultured flounder, of 0 age Paralichthys olivaceus, in Cheju-do. Typical symptoms of the diseased fish were the hemorrage of the opercle, discoloration of the body, exophthalmus and hemorrhage of the eyes. The causative organism isolated from diseased fish was identified as a $\beta$-hemolytic Streptococcus. This bacterium was not identical with any known Streptococcus species listed in Bergey's Manual of Determinative Bacteriology 8th edition. However there was a close similarity between this species and Streptococcus sp. isolated from flounder and reported by Tashio (1983). The isolated bacteria streptococcus sp. showed very high sensitivity to the SM and EM, however, it resisted to the high concentration of Penicillin. In the pathagenicity analysis, about $1.1{\times}10^9$, $1.1{\times}10^7$, $1.1{\times}10^5$, $1.1{\times}10^3$, $1.1{\times}10^1cells$/100g B.W of isolated bacteria were injected percutaneouly. The results showed that this inoculation size $1.1{\times}10^3cells$/100g B.W was the threshold for the induction of mortality in pathogenicity analysis.
