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 evaluate the factors affecting foveal threshold measured by blue on yellow perimetry in moderate to severe open angle glaucoma. METHODS: Fourteen eyes of 14 patients who were diagnosed as moderate to severe open angle glaucoma underwent macular threshold test of the Humphrey Field Analyzer using white and blue targets. The foveal threshold using white targets (white threshold) was more than or equal to 18 dB in all cases. The cases of foveal threshold using blue targets (blue threshold) less than or equal to 0 dB were defined as foveal sensitivity loss group (7 eyes) and those more than 0 dB as no foveal sensitivity loss group (7 eyes). Those of age, contrast sensitivity, visual acuity, refraction, mean deviation, pattern standard deviation, corrected pattern standard deviation, vertical and horizontal C/D ratio, foveal white threshold, intraocular pressure, any point within central 5degrees with sensitivity less than or equal to 0 dB in visual field test were statistically analyzed between the two groups. RESULTS: Foveal white threshold and any point within central 5degrees with sensitivity less than or equal to 0 dB in visual field test showed significant difference between the two groups. CONCLUSION: Foveal dysfunction represented as decrease in blue threshold is possibly related to the paracentral scotoma which means any point within central 5degrees with sensitivity less than or equal to 0 dB in moderate to severe open angle glaucoma. However, significant deficits in either visual acuity or white threshold were not presented.

PURPOSE: To find clinical factors related to the long-term outcome of binocularity in accommodative esotropia. METHODS: Forty-nine patients with accommodative esotropia who were followed over 5 years after successful optical alignment within 8 prism diopters of orthophoria at near and distance with glasses including bifocals were included. The patients who had stereo acuity better than 50 seconds/arc and central fusion without suppression scotoma at the final visit were divided into the bifoveal fusion group and the others were divided into the peripheral fusion group. Clinical factors were analyzed between the two groups (Chi-square test, student t-test). RESULTS: Of the 49 patients, 15 patients were included in the bifoveal fusion group and 34 patients were included in peripheral fusion group. Mean follow-up was 88.9 +/- 25.4 months. Clinical factors that were significantly related to the bifoveal fusion group were older age of onset, shorter duration of misalignment, intermittent esotropia at the initial visit and after initial optical correction, smaller residual deviations at distance after initial optical correction and at the final visit, and lesser amblyopia. CONCLUSIONS: To obtain better levels of long-term binocularity, optical correction should be done as early as possible, before the presence of constant eye misalignment or amblyopia, and the residual esodeviations after optical correction should be kept as small as possible.

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.

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.
