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.

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.

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.

PURPOSE: To report two cases of photic retinopathy induced by excessive exposure to sunlight and operation microscope during cataract surgery. METHODS: Two cases of photic retinopathy(case 1: a 33 year old woman exposed to excessive sun light, case 2: a 66 year old woman exposed to direct operating microscope during cataract surgery) were followed and observed with visual acuity, fundus examination and fluorescein angiography without specific treatment. RESULTS: In both cases, best corrected visual acuity was improved to 1.0 and central scotoma decreased significantly.

Patients with central serous chorioretinopathy complain of decreased vision, micropsia, metamorphopsia, and central scotoma due to sensory retinal detachment. Morphologic characteristics of the sensory retinal detachment were described using Heidelberg retina tomograph. We inspected the changes in morphology according to certain time interval in 28 eyes and correlated them with the changes in visual acuity and symptoms. The mean width,length, height, area and volume of the detached sensory retina at initial examina- tion were 2.86 +/-1.08 mm, 2.60 +/-0.97mm, 0.30 +/-0.10mm, 6.82 +/-4.70mm2 and 0.77 +/-0.68mm3, respectively. Of the 7 eyes that had been followed, improvement of vision preceded improvement of other symptoms but, this was not statistically significant. The extent of sensory retinal detachment reduced with time and the maximal reduction occurred during the first month from the initial visit. The volume reduction (87.4%) was greater than the area reduction (52.3%) at the time of visual improvement

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.

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).

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.

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.
