The author had been experienced one case of ophthalmic migraine recently and was reviewed the liturature. Variability of symptoms and periodicity are characteristic feature of the migraine Syndroms. In this case, periodic scintillating scotoma, which developed abruptly, was revealed congruous in the right homonymous fields, lasting about 30 minutes. Scintillating scotoma refers to the migraneous scotoma with the shimmering border. This illuminated dancing border takes the form of "fortification figures". The Author was concerned particularly about the variable symptoms and pathogenesis of aphthalmic migraine.

This analysis describes the influence of miotics (pilocarpine) on the visual field obtained from the Goldmann perimetry testing of 10 ocular hypertensive eyes (7 patients) and 10 glaucomatous eyes (8 patients) by comparison of two visual fields testing at miotic state and at normal pupil size. The analysis of visual field was done by Esterman grid for functional estimation and by section paper for gross evaluation. The results were as follows; 1. Decreased pupillary size caused not only the decrease of the gross visual field but also the decrease of the functional visual field. 2. Absolute scotoma was not influenced by the pupillary size.

Author presented nine patients of eye toxicity from Ethambutol. They used daily the drug, 15~30mg per kilogram body weight during the period of one month to six months. With the relationship of drug induced toxic amblyopia and optic neuritis, seven patients out of nine showed severe visual disturbance. Five of them have the peripheral constriction. Three cases showed relative ring scotoma and one case showed relative central scotoma.

The damaging effect o flight on the eye has been recognized for centuries. Solar retinopathy is a well-recognized clinical entity of retinal damage caused by direct or indirect exposure to the sun. Symptoms of solar retinopathy include decreased vision, metamorphopsia, micropsia, and central or paracentral scotoma. Typical solar retinopathy presents clinically as a small yellowish-white foveolar lesion. The authors experienced a case of solar retinopathy which occurred in a 25-year-old female on both eyes upon gazing at the sun for 4 hours.

PURPOSE: To investigate the association between corneal biomechanical properties and initial visual field defect pattern in normal tension glaucoma using an Ocular Response Analyzer (ORA; Reichert Instruments, Depew, NY, USA). METHODS: Forty-one patients with normal tension glaucoma were divided into 2 subgroups, 21 patients with initial paracentral scotomas and 20 patients with initial peripheral scotomas. The corneal biomechanical properties of corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg), corneal-compensated IOP (IOPcc) measured by the ORA, central corneal thickness, and Goldmann applanation tonometry were comparatively analyzed between the 2 groups. RESULTS: The patients with initial peripheral scotomas were significantly younger than those with initial paracentral scotomas (49.45 ± 13.33 years vs. 58.14 ± 12.49 years, p = 0.035) and showed more myopia (− 2.42 ± 2.22 diopter vs. − 0.89 ± 2.22 diopter, p = 0.034). The mean CRF was significantly lower in the initial paracentral scotoma group than in the initial peripheral scotoma group. (9.45 ± 1.95 mmHg vs. 10.58 ± 2.05 mmHg; p = 0.041). No significant difference in CH, IOPg, or IOPcc was seen between the groups. CONCLUSIONS: CRF was significantly different between the initial paracentral scotoma group and initial peripheral scotoma group in normal tension glaucoma. Thus, CRF may be useful to predict initial central field loss in normal tension glaucoma.

Stargardt's disease, first described in detail by Stargardt in 1909, is a recessively inherited macular dystrophy which evidences itself by reduced visual acuity, bilaterality, slowly progressive lesion, occurring familially, starting in youth (8 to 15 years). We have recently seen macular dystrophies occurring in siblings, three out of six. All developed this disease between 9 to 15 years and vision deteriorate progressively to the adult hood. Ophthalmoscopic examination revealed slight pale dise, narrowing of retinal vessels, definite alterations in the macular region associated with the development of red-yellow flecks in the center surrounded by yellow-white flecks in the paracentral region. Angiogram showed the evidence of marked alteration in the retinal pigment epithelium on the macula bilaterally. All cases were noted by ring shaped area of mottled hyperfluorescene but central flecks were nonfluorescent. Field examination showed the central scotoma to a small targets and ERG the subnormal in photopic and scotopic responces. The Ishihara test disclosed a mild to moderate red-green dyschromatopsia.

A 27-year-old woman suffered a sudden visual disturbance in the right eye. The right eye had a visual acuity of 0.02 and a relative afferent pupillary defect. A visual-field examination revealed an inferotemporal field defect in the right eye. A fundus examination revealed no abnormalities that were responsible for the visual-field defect. Multifocal electroretinography showed decreased responses in the right eye at the corresponding area with the visual-field defect. She was diagnosed as acute zonal occult outer retinopathy.

Optic neuritis is an acute inflammatory disease of the optic nerve. Visual loss in optic neuritis is typically sudden and accompanied visual field defects. We attempted to characterize the clinical manifestations of optic neuritis based on visual acuity and visual field changes. Eighteen patients were included in this study who completed at least 3 month follow-up. we observed these patients with no medication in ten, with oral prednisolone in seven and with intravenous methylprednisolone in one. Statistically significant visual recovery occurred at first and second month and twenty eyes of 27 eyes (74%) had improved o.5 or more. Most common type of visual field defect was central scotoma (74%) and 85% of eyes who showed abnormal visual fields at first visit recovered normal visual field during follow-up period.

The authors reported a case of congenital coloboma of iris, choroid, optic nerve in both eyes, with tne review of literatures. The patient was a 19 year old male, and there was no family history. This case was typical colocoma, associated with persistent pupillary membrane. The scotoma corresponding to choroid coloboma was seen in the left eye, but not in the right eye.

PURPOSE: We report a case of subfoveal choroidal neovascularization following multiple evanescent white dot syndrome (MEWDS). METHODS: A 28-year-old female patient with vitreous floater and scotoma of her right eye was diagnosed with MEWDS. Fundus examination revealed multiple white dots at midperipheral retina, and a granular appearance of macular, which were nearly subsided at 1 month after her first visit. She complained of a sudden decrease in visual acuity of right eye at 3 months after her initial episode of MEWDS. Fundus examination showed macular hemorrhage with edema. Typical subfoveal choroidal neovascularization with leakage was confirmed by Indocyanine Green Angiography (ICGA), which was treated by photodynamic therapy (PDT). RESULTS: Subfoveal choroidal neovascularization following MEWDS is rare, and this is the first Korean case report.
