Purpose: To present a case of leukemic infiltration of the optic nerve head as the initial manifestation of leukemic relapse. Case summary: A 65-year-old woman was diagnosed with acute myeloid leukemia. Complete remission was achieved after 4 complete courses of chemotherapy. She complained of a sudden decrease in visual acuity in her left eye. Fundus examination showed severe optic disc edema with peripapillary hemorrhage and serous retinal detachment. Visual acuity and fundus continued to aggravate and high-dose intravenous steroid therapy was instituted. Visual acuity and fundus deteriorated more after treatment. Brain magnetic resonance imaging and CSF study were normal but intrathecal chemotherapy and focal irradiation were performed on account of the suspected CNS involvement of leukemia. Morphologic improvement in the retinal structure was achieved, however, optic atrophy remained and her vision did not recover. Conclusions: The present case shows the involvement of the optic nerve head as the initial isolated manifestation for the relapse in a patient with complete remission. CNS involvement is rare in acute myeloid leukemia and in particular, the optic nerve is rarely reported as the initial isolated presentation for the relapse. Moreover, the disease progression relatively aggravated after treatment. In the atypical aspects of leukemic relapse, the present case was noticeable. J Korean Ophthalmol Soc 2011;52(2):250-254

Purpose: To report a rare case of choroidal metastasis from renal cell carcinoma. Case summary: A 61-year-old man visited our clinic with the chief complaint of decreased vision in the right eye. Three years earlier, he underwent right nephrectomy due to renal cell carcinoma. Best corrected visual acuity was 0.2 in the right eye and 1.0 in the left eye. Fundoscopic examination of the right eye revealed a yellowish, dome-shaped elevated choroidal mass with serous retinal detachment, measuring 5.0 × 4.0 disc diameter and located lateral to the macular area. Systemic evaluations showed multiple lung and brain metastases. A diagnosis of choroidal metastasis from renal cell carcinoma was made for the right eye, and the patient received local treatments with oral sorafenib therapy, composed of subtenon triamcinolone injection and intravitreal ranibizumab injection. Tumor progression continued, and visual acuity declined to hand motion. Enucleation was recommended, but the patient refused and is on a regular follow-up after transpupillary thermotherapy. Conclusions: Ocular manifestation may be the initial presenting sign of a recurrent tumor, and an extensive systemic evaluation for metastatic malignancy should be performed. The present example showed a rare case of choroidal metastasis from renal cell carcinoma. J Korean Ophthalmol Soc 2012;53(6):880-885

Describing Verb Conjugation in Korean Language Education. To learn how verbs conjugate is one of the most important and difficult task for foreign learners of Korean language. This study examined how regular and irregular conjugation is dealt in Korean grammar guide books for Korean language teacher and Korean grammar textbooks for foreign learners. As results, we found that the concept of irregular verbs, in both its definition and scope, were often not coherent. In addition, a lot of types of conjugation seemed to be undescribed. To solve these problems, this study suggested the classification of conjugation. We categorized them into two basic types(phonologically and lexically conditioned) and presented conjugation list for each category. We also suggested that all types of conjugation should be designated according to stem-final forms rather than alternational forms.

A reforming catalyst for hydrogen production from ammonia is being studied. Non-novel metal based Ni catalysts for use in ammonia reforming processes are being developed. In this study, the ammonia reforming characteristics according to Ni content of the alumina pellet supported catalyst in the mid-temperature region were investigated under different space velocity. 20 Ni and 3,000 h<SUP>-1</SUP> showed the best catalytic activity with ammonia conversion of 63% among all conditions.
