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.

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.

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.

We observed a patient who had central retinal artery occlusion with severely reduced visual acuity and characteristic retinal changes after cervical spine surgery under general anesthesia. In acute stage, visual acuity was slightly improved. But over course of several months, there was no improvement in visual acuity and central scotoma was remained. There were no evidences of hypotension or anemia during operation. The only presumptive cause was direct external ocular compression by horseshoe headrest. It is necessary to pay attention to eyes when prone positioning in the patients of cervical spine surgery.

In 11(64.7%) of 17 eyes treated by intravitreal gas injection, the retinas were successfully attached during follow-up period that ranged from 12 to 39 months. Group I(detachment limited to the perimaculararea) patients need more frequent gas injection than group II(detachment extending to equator), but success rate of group I(83.3%) is higher than group II(66.7%). Group III(detachment with peripheral retinal break) patients are not successful by gas injection only. In the succesful eyes, macular holes are not visible, but "window defects" are present on FAG. The relative scotomas improve. Recurrent detachment cases(31.3%) are associated with posterior staphyloma, peripheral retinal break and trauma. Time of late recurrences ranged from 4 to 13 months postoperatively(mean: 7 months).

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.

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.

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.

Multiple evanscent white dot syndrom(MEWDS) has the characteristic clinical, funduscopic, fluorescein angiographic and electrophysiologic findings. The etiology of MEWDS remains unknown. The authors report on two patients with MEWDS. They were young females. Funduscopic examination showed that multiple, white dots are found at the level of the retinal pigment epithelium. These dots extended from macula into mideriphery. Also, the patients had a tiny, granular gray-white dots in the fovea. Fluorescein angiography showed an early hyperfluorescence in the areas corresponding to the white dots with late staining. Two patients had spontaneous recovery of vision in four to seven weeks. They had persistent enlargement of the physiologic blind spot or paracentral scotoma in their visual field, respectively.
