BACKGROUND: The incidence, clinical manifestations, and contributory factors in ethambutol-induced optic neuropathy (EON) have not been widely studied. METHODS: A retrospective chart review of 857 patients who took ethambutol for treatment of tuberculosis identified 89 patients who complained of decreased vision after initiation of treatment and were therefore referred to the ophthalmology clinic of Seoul National University Hospital, Korea, between January 2003 and December 2005. Information wa

BACKGROUND: Key clinical features of chronic relapsing inflammatory optic neuropathy (CRION) include relapsing inflammatory optic neuritis (ON) and steroid dependency, both of which have been reported among patients with myelin oligodendrocyte glycoprotein antibodies (MOG-Abs). We investigated the relevance of the presence of serum MOG-IgG with the current diagnostic criteria for CRION among patients with idiopathic inflammatory optic neuritis (iON). METHODS: Retrospective reviews of a database

Chorioretinal lesions are not uncommon in patients with CGD and they may affect vision. Regular screening of patients with CGD and long-term follow-up of CGD chorioretinopathy patients should be performed to define the lesion, natural history, and pathogenesis.

Preoperative VA is a prognostic factor for postoperative VA and VF. Preoperative VF is predictive of postoperative VF and postoperative VA in cases with severe VF loss.

OBJECTIVE: Anterior cervical discectomy and fusion (ACDF) is often complicated by subsidence, pseudoarthrosis, kyphosis, and graft donor site morbidities. To decrease the occurrence of these complications, various types of cages have been developed. We designed this retrospective study to analyze and compare the efficacy and outcomes of ACDF using double cylindrical cages (DCC) (BK Medical, Seoul, Korea) versus an anterior cervical plating system with autogenous iliac crest grafts. METHODS: Fort

Importance: A proportion of people with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) have a relapsing disease course and persistent anti-myelin oligodendrocyte glycoprotein immunoglobulin G (MOG-IgG) seropositivity. Few studies have investigated whether treatment of the first MOGAD attack is associated with the long-term disease course and/or MOG-IgG seronegative conversion. Objective: To investigate the association of time to treat the first acute MOGAD attack with re

이 글은 대수 교육과정을 개선하려는 여러 움직임 가운데 초등수학을 중심으로 하는 ‘초기대수’(early algebra)에 관한 것이다. 초기대수는 중등학교 대수 교육과 관련해서 발생하는 여러 문제를 초등수학의 재음미를 통해 해결하려는 시도로, 이것은 1980년대 ‘대수적 사고’를 학교대수에서 강조하려는 움직임과 함께 시작한 것이다. 초기대수는 대수를 기호가 아닌 추론 측면에서 논의하는 것으로, 기호 이전에 등장한 대수적 사고와 학생들의 심리적 발달을 고려해서 그 지도 가능성이 제시되고 있다. 이러한 초기대수와 관련된 연구는 1990년대 이후 미국을 비롯해서 네덜란드와 호주 등 각국에서 현재 진행 중에 있다. 한편 이 글은 우리의 초등수학 교과서를 분석하고, 이를 통해 초기대수와의 관련성에 대해 논의하였으며, 대수 교육과정의 개선이 초등수학에서부터 단계적으로 시작될 수 있음을 강조하고 있다.

Classification of IXT based on the degree of near stereopsis offers a useful tool for the assessment of initial sensory status as well as postoperative prognosis. Also, a lower age at first detection of IXT and a lower best-corrected visual acuity were associated with poor near stereoacuity.

BACKGROUND: To evaluate the effectiveness of binocularity-stimulating treatment in children with residual amblyopia following occlusion therapy for more than 6 months. METHODS: Of patients with amblyopia caused by anisometropia and/or strabismus, patients with residual amblyopia following more than 6 months of occlusion therapy were included. Subjects underwent one of the following types of binocularity-stimulating therapy: Bangerter foil (BF), head-mounted display (HMD) game, or BF/HMD combinat
