1.Electroretinographic Changes Experimentally Induced by the Intraocular Copper.
Journal of the Korean Ophthalmological Society 1968;9(2):1-5
Copper fragment was introduced into the vitreous body of fourteen albino rabbits through the scleral incision at equatorial region. Both photopic and scotopic ERGs were recorded for 30 days thereafter stimulated by the electronic photoflash of 2 msec duration.The changes in scotopic b-potential were roughly classified into 3 types. The first type (5 eyes) showed acute, severe reduction, extinguishing from 6 to 24 days. The second type (3 eyes) was characterized by the absence of any remarakble changes during the whole observation period, the final b'potential being 82,4% of the original value. In the third type (6 eyes), the b-potential decreased gradually and 24.3% of the pre' operative value was attained after 30 days. The latent time and the implicit time of the b-potential increased proportionally to the reduction of the b-wave. The scotopic a-wave behaved parallel to the b-wave, and in later stage, negative (-) type of ERGs were frequently encountered. The photopic a- and b-waves changed in the similar way as the scotopic a- and b-waves, respectively. The slitlamp biomicroscopy and ophthalmoscopy revealed the fibrous tissue proliferation around the copper fragment in relatively early stage. When the proliferation progressed and extended into the vitreous body, ERG showed reduction in b-potential, and sometimes increase in b-potential was noted In cases in which connective tissue encapsulated the copper and did not extend into the vitreous body, ERG changes were much milder and slower. In histological sesctions performed 2 weeks and 3 weeks after the insertion of copper fragment, the degeneration of the retina began both in the visual cell layer and ganglion cell layer almost simultaneously. When the ERG was extinguished, the retinal tissue showed complete destruction.

We have experienced a case of plexiform neurofibrorna of the right upper eyelid and orbit in a 12-year-old girl who had typical skin features of neurofibromatosis and no family history. The non-pulsating proptosis of the right eye and diffuse thickening with hypertrophy of the upper lid, had increased insiduciusly since the birth on. Biopsy taken from eyelirl lesion showed the features of plexiform neurofibroma. Skull X-ray and brain computerized tomogram showed that the right orbit was wider, with the enlarged mass and defects in orbital roof and lesser and greater wings of the sphenoid bone. The surgical excision of the right eyelid lesion was performed.

BACKGROUND: To find out characteristics and classification of toxic agents by clinical analysis of pediatric poisoning and to determine the clinical availability of grading by using MSPC score. METHOD: Subjects were patients under 15 years exposed to toxic agents, who visited Ajou university hospital emergency center from June, 1994 to October, 1997. The study was performed retrospectively. RESULTS: The subjects were 126 cases and male to female sex ratio was 1.2:1. Mean age was 29+/-30 months old. The most common route of exposure was ingestion, following contact, inhalation and bite. The most common reason was mistake by the patient, following mistake by caregiver, suicide attempt and accident. The MSPC score distribution of symptomatic patient was as follows; 1 point: 26 cases(63.4%), 2 point: 12 cases(29.2%), 3 point: 1 case(2.4%), 4 point: 2 cases(4.8%). The classification of exposed poison was as follows; therapeutic drugs: 29 cases(23.0%), non-therapeutic drugs: 97 cases(73.0%). The most common exposed poison was household products: 23 patients(18.3%) were admitted to hospital. CONCLUSION: There was statistically significant difference in the classification of poison, MSPC score, treatment modality at hospital, first follow up period after discharge between admitted group and non-admitted group. There was statistically significant difference in the reason of exposure, route of exposure, MSPC score, admission period according to patient's age. severity grading according to MSPC score is regarded as an available method to determine the modality of management.

Chondrodysplasia punctata is a rare congenital disorder of bone, occuring in infants, which is characterized by radiographic manifestation of premature deposition of punctate calcific densitiy in epiphyseal areas, preformed in cartilage. We experienced a case of rhizomelic type-chondrodysplsia punctata in a two day old female who showed short stature, symmetric shortening of proximal limbs, cataract, icthyositic skin lesion and characteristic coronal clefts in lumbar vertebral bodies on X-ray.

8.The Effect of Subconjunctival Injection of Hypertonic Saline Solution.
Journal of the Korean Ophthalmological Society 1967;8(1):33-34
The effects of subconjunctivally injected normal saline and hypertonic saline solution on the choroidal blood flow in albino rabbits were investigated. By the injection of 0.9% saline solution, no significant changes in the choroidal blood flow took place. Subconjunctival injection of 3% saline solution produced increase in the blood flow which continued for 30 minutes. The average increase was 22%. Hot dry compress by infra-red lamp for 10 minutes increased also the blood flow by 41 % which lasted for 20 minutes after cessation of hot compress.

In glaucoma patients, optic nerve head analysis is very useful in early detection and progression during follow-up. Among optic nerve head analysis methods, the confocal laser tomographic scanner(Heidelberg Retina Tomograph: HRT) is actively studied for accurate and highly reproducible analysis.We analyzed the optic nerve head of 62 normal eyes(male 40 eyes, female 22 eyes) in third decade of Korean with HRT, and calculated the mean value of each parameters in HRT and evaluated the difference between men and women. We also studied the distribution fo the value of each parameter in normal third decade of Korean. In addition, for the parameters of Rim/Disc area ratio, we calculated the mean value in 6 divisions of optic nerve head.The mean value of Disc area was 2.039mm3, Cup area 0.593mm3, rim area 1.716mm3 and Cup/Disc area ratio 0.237. Rim volume, Maximal cup depth, Height variation contour, Mean retinal nerve fiber layer thickness, and Retinal nerve fiber layer cross sectional area were statistically different between men and women. For Rim/Disc area ratio, the maximal value was noted in nasal inferior(0.873) region, and the minimal value was in temporal(0.579) region. There was no statistically difference between men and women in Rim/Disc area ratio.

10.Urinary Cytology in the Diagnosis of Urothelial Carcinoma.
Korean Journal of Urology 1986;27(6):865-870
The cytologic examination of the urine is very simple and inexpensive procedure for the detection and follow up the genitourinary tumors, and worthy as a mass screening test. The voided urines of 20 patients who were admitted to the department of urology, Seoul city hospital from October 1983 to September 1985 with the diagnosis of bladder carcinoma were analysed as to variations in PH and osmolality values and quality of cytologic smears. The same analyses were repeated after addition of trichloracetic acid (TCA) and after diuresis was obtained by Furosemide medication. Standardization of values of PH (average 2) and of osmolality (average 300 mosm/kg) was obtained by adding TCA to furosemide urine. The cellular smears of this TCA treated furosemide urine exhibited the finest cytological details when compared to the smears obtained by routine method.
