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.

Authors experienced 100 cases of retrobulbar optic neuritis among the patients who visited the Chang Shoo Choi Eye Clinic during the last 2 years, from September 1, 1964 to August 31, 1966. The chief complaints are asthenopia, blurring vision, ocular pain, headache and photophobia. Of 100 cases, 46 cases wanted to be refracted. The corrected visual acuities are not always poor, though they are very variable from time to time as the tests are processing. The most cases revealed central relative scotomas instead of cecocentrals as previously believed. Fields are taken with glasses if corrected. In our cases, the age distribution of the patients are very interesting, the most susceptible age groups are 11~13 years.

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.

Tangential vitreoretinal traction around fovea is known to be the principal cause in the pathogenesis of idiopathic macular holes. According to the recent study, the internal limiting membrane(ILM) may provide a scaffold for fibroblast proliferation and contraction, therefore play an important role in the enlargement of macular hole. We removed the ILM during macular hole surgery and assessed the anatomical and functional outcome of the macular hole surgery. Twelve consecutive patients with full-thickness macular hole were enrolled in this study. They were examed for best-corrected vision, fundus photography, fluorescein angiography, Humphrey automated perimetry, focal eletroretinogram, before and after surgery. After surgery, vision was improved in 8 eyes(67%), hole was closed in 10 eyes(83%). Macular thresholds on visual field was increased in 8 eyes and peripheral scotomas developed in 3 eyes postoperatively. The amplitude increased in 7 eyes and the implicit time decreased in 8 eyes on focal electroretinograms postoperatively. Out results suggested that the complete removal of ILM should be attempted to improve vision and to close holes during the full-thickness macular hole surgery.

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.

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.

The Leber's hereditary optic neuropathy, which affects mainly males in the late teens or in the early twenties, is a rare inherited disorder characterized by bilateral rapid loss of central vision. Leber's disease undergoes like optic neuritis in acute stage, but in late stage it results in optic atrophy with severe impairment of visual acuity and absolute central scotoma. Recently the authors have experienced two cases of Leber's optic neuropathy in a family. We observed a patient whose visual acuity of right eye was 0.8 at first examination, but reduced to 0.04 by 2 months after onset in spite of medical treatment, So we described the characteristic clinical findings of Leber's disease with brief review of the literatures.
