PURPOSE: To report a case of optic neuritis difficult to differentiate from ischemic optic neuropathy and optic nerve glioma. CASE SUMMARY: A 63-year-old male visited our clinic because of a sudden painless decrease in visual acuity in his right eye. He had a relative afferent pupillary defect and inferior altitudinal scotoma with disc pallor in his right eye. Ischemic optic neuropathy was suspected based on these clinical observations. However, a focal enhancing lesion was found in the intracranial portion of the right optic nerve on gadolinium-enhanced T1-weighted MRI. The radiologist's report revealed right intracranial optic glioma. Optic neurectomy was planned in accordance with the suspicion for optic glioma. However, a systemic mega-dose methylprednisolone therapy which is relatively less invasive was performed first based on the decision that optic neuritis should be distinguished from optic nerve glioma. The patient was hospitalized and 1 gram of methylprednisolone was injected intravenously daily for 3 days. The patient's visual acuity in the right eye improved from 0.1 before treatment to 0.3 after treatment. MRI scans at 8 months after steroid treatment showed disappearance of the previously enhanced lesion suspicious for optic glioma with developed atrophic change. The patient was finally diagnosed with optic neuritis based on these results. CONCLUSIONS: Careful differential diagnoses and therapeutic approaches to possible diseases are necessary because optic neuritis can manifest as a variety of clinical entities and imaging findings.

5.Clinical Studies on Ischemic Optic Neuropathy.
Journal of the Korean Ophthalmological Society 1973;14(4):368-382
The author observed 9 cases of ischemic optic neuropathy and the following clinical findings were obtained. 1) Probable underlying causes of them were arteriosclerotic four cases, syphilitic two cases and oral contraceptives, acute carbon monoxide and undetermined one case, respectively. 2) To detect this disease in the early stage was hard because of systemic and/or other ocular diseases were associated. 3) The prognosis was better in patients to whom early diagnosis and treatment was given. 4) The best diagnostic procedure was to check visual field. 5) Good therapeutic effects were obtained by administration of corticosteroids and vasodilators.

We describe a patient with Churg-Strauss syndrome who developed unilateral anterior ischemic optic neuropathy. A 54-year-old man with a history of bronchial asthma, allergic rhinitis, and sinusitis presented with sudden decreased visual acuity in his right eye that had begun 2 weeks previously. The visual acuity of his right eye was 20 / 50. Ophthalmoscopic examination revealed a diffusely swollen right optic disc and splinter hemorrhages at its margin. Goldmann perimetry showed central scotomas in the right eye and fluorescein angiography showed remarkable hyperfluorescence of the right optic nerve head. Marked peripheral eosinphilia, extravascular eosinophils in a bronchial biopsy specimen, and an increased sedimentation rate supported the diagnosis of Churg-Strauss syndrome. Therapy with methylprednisolone corrected the laboratory abnormalities, improved clinical features, and preserved vision, except for the right central visual field defect. Early recognition of this systemic disease by ophthalmologists may help in preventing severe ocular complications.

Giant cell arteritis (GCA) is a rare disease among Asians. Arteritic anterior ischemic optic neuropathy, which accompanies GCA, has not yet been reported in Koreans. Diagnosis of GCA is difficult if typical symptoms other than visual loss are absent. Here, we report a case of an 83-year-old Korean woman presenting with sudden visual loss in both eyes (oculus uterque, OU). Her visual acuities included perception of light in the right eye (oculus dexter, OD) and perception of hand motion in the left eye (oculus sinister, OS). The results of the Hardy-Rand-Rittler test and Ishihara test showed total dyschromatopsia OU. The Goldmann perimetry test revealed a total field defect OD and paracentral island OS. Fundus examination revealed chalky-white disc swelling OU. Other systemic symptoms and signs were unremarkable. The erythrocyte sedimentation rate, C-reactive protein and platelet count were highly elevated. Temporal artery biopsy revealed multiple lymphocytes and multinucleated giant cells in the arterial media layer. To our knowledge, this is the first report of GCA in a Korean that has been confirmed with temporal artery biopsy. In conclusion, silent GCA can occur in Koreans, and hence, elderly patients presenting with chalky-white disc swelling, and corresponding laboratory findings must be evaluated for GCA.

A 57-year-old woman experienced bilateral acute ischemic optic neuropathy after spine surgery. Routine MR imaging sequence, T2-weighted image, showed subtle high signal intensity on bilateral optic nerves. A contrast-enhanced T1 weighted image showed enhancement along the bilateral optic nerve sheath. Moreover, diffusion-weighted image (DWI) and an apparent diffusion coefficient map showed markedly restricted diffusion on bilateral optic nerves. Although MR findings of T2-weighted and contrast enhanced T1-weighted images may be nonspecific, the DWI finding of cytotoxic edema of bilateral optic nerves will be helpful for the diagnosis of acute ischemic optic neuropathy after spine surgery.

PURPOSE: We evaluated fundus and fluorescein angiography (FAG) findings and characteristics that can help distinguish nonarteritic anterior ischemic optic neuropathy (NAION) from optic neuritis (ON). METHODS: Twenty-three NAION patients and 17 ON with disc swelling patients were enrolled in this study. We performed fundus photography and FAG. The disc-swelling pattern, hyperemia grade, presence of splinter hemorrhages, cotton-wool spots, artery/vein ratio and degree of focal telangiectasia were investigated. The FAG findings for each patient were compared with respect to the following features: the pattern of disc leakage in the early phase, arteriovenous (artery/vein) transit time (second), and the presence and pattern of the filling delay. RESULTS: Cotton-wool spots, focal telangiectasia, and venous congestion were more common in the affected eyes of NAION patients. Upon FAG, 76.5% of the patients in the ON group exhibited normal choroidal circulation. However, 56.5% of patients in the NAION group demonstrated abnormal filling defects, such as peripapillary, generalized, or watershed zone filling delays. CONCLUSIONS: Fundus findings, including cotton-wool spots, focal telangiectasia, and venous congestion in the affected eye, may be clues that can be used to diagnose NAION. In addition, choroidal insufficiencies on FAG could be also helpful in differentiating NAION from ON.
