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.

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

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.

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.

To maintain the function of central vision from the sensory retina at the macular area, we performed macular trasnlocation for the treatment of subfoveal lesion. Laser photocoagulation hardly avoid central scotoma and surgical removal of neovascular membrane tends to result in poor visual outcome because of the unhealthy underlying retinal pigment epithelium. We performed macular translocation in four patients with subfoveal lesion using modified macular translocation technique. Surgical steps include trans pars plana vitrectomy, creation of a retinal detachment, scleral shortening, air-fluid exchange and gas injection. The results were the increased visual acuity in two patients and the improved symptom in two patients. Our result suggested that the macular translocation procedure may be considered as a therapeutic modality for the treatment of patients with subfoveal lesion.

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.

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.
