Statistical Observation for the Clinopathological Analysis of the Eye Diseases

We had analyzed statistically the clinical and histopathologic review of 103 cases of the eye diseases for 5 years at department of ophthalmology, Soonchunhyang University Hospital. The results were as follows; 1. The cases of biopsy among 57569 out-patients were 103 cases(0.01%). 2. The sexual distribution revealed 59 males(57.3%) and 44 females(42.7%). 3. The evaluation of the site of the involved eyes showed that 53 cases(51.5%) were right eye, the left eye were 48 cases(46.0%) and binocular were 2 cases(2.5%). 4. The primary sites of disorders were lid(41.7%), eyeball(32.0%), conjunctiva(21.4%), orbit(2.1%), cornea and lacrimal system in order of frequency. 5. According to age, the largest group was in the age first and second decades, and the smallest group in 5th decade. 6. As a single disease, nevus, eyeball rupture and cyst were relatively high in incidence. 7. The proportional rate of the correct diagnosis was 58 cases(56%) among 103 cases. 8. The most common cause of enucleation was eyeball rupture(trauma), 15 cases.

Survey on the Causes of Blindness Among the Hospital Patient in 3 Districts

We surveyed the causes of blindness among the 6692 eye patients of 3 hospitals(Seoul, Chunan, Kumi) in 1984. Blindness is defined as visual acuity of 0.1(20/200) or less in better eye with best correction. The representation of the diagnosis of the ocular diseases is based on the examination of the ophthalmologists. The estimated number of blindness is 259(6.74%)in Seoul, 106(8.92%) in Chunan, 70(4.21%) in Kumi with total of 435(6.5%) among the 6692 eye patients. The leading causes of blindness for individual districts are cataract(28.19%), retinal and vitreous diseases(20.46%), trauma (15.06%), diseases of optic nerve(10.81%), corneal diseases(8.10%) in Seoul; cataract(35.81%), corneal diseases(18.87%), global diseases(13.21%), trauma(10.38%), retinal and vitreous diseases(6.60%) in Chunan; and cataract(34.29%), corneal diseases(14.21%), trauma (12.86%), global diseases(8.57%), retinal and vitreous diseases(8.50%) in Kumi. Rates of the blind eyes for the age groups are; 1.2%(under the age of 5), 4.1%(6~9), 10.3%(10~19), 30.8%(20~39), 23.5%(40~59), and 30.1%(above 60). Important causes of blindness in each age group are trauma(43.48%), optic nerve diseases(13.04%), and global diseases(13.04%) for below the age of 10, trauma(28.89%), retinal diseases(17.78%), and optic nerve diseases(13.33%) in 10~19 age group, corneal diseases(19.40%). cataract(18.66%), and retinal diseases(16.42%) in 20~39 age group, cataract(28.43%), retinal diseases(18.63%), and corneal diseases(10.78%) in 40~59 age group and cataract(59.54%), retinal diseases(9.92%), and glaucoma(8.40%) for above 60. There are no significant differences between male and female, right eyes and left eyes in the causes of the blind eyes, and also we make some comparisons with different statistics of domestic and foreign countries.

A Case of Acute Posterior Multifocal Placoid Pigment Epitheliopathy

Acute posterior multifocal placoid pigment epitheliopathy usually occurs in young or middle-aged adults and is usually bilateral. This syndrome is characterized by the acute onset of multiple, flat, yellow-white lesion of the posterior pole at the level of the retinal pigment epithelium and by the rapid loss of vision. These lesions resolve spontaneously, leaving extensive degeneration of pigment epithelium within a few weeks and visual acuity spontaneously improves in most cases. In the acute stage, fluorescein angiographic appearance of condition is characterized by placoid lesions blocking transmission of choroidal fluorescence in the initial phase, which are gradually stained and fluorescence faintly in the late phase. Older lesions represent residual defects in the pigment epithelium and appear as transmission defect without late staining or leakage of dye. Authors experienced and treated a case of acute posterior multifocal placoid pigment epitheliopathy in 19-years old male patient, and had a good visual improvement.
