Retinal hemorrhages in the newborn infant were first described shortly after the invention of the ophthalmoscope(Jaeger. 1961). Frequency of the retinal hemorrhages in the newborn infant has been reported to be between 2.6 and 50%. We postulate that the retinal hemorrhages are caused by maternal factors and fetal factors. Maternal factors include delivery type, maternal age, duration of pregnancy, parity, duration of labor, and maternal blood pressure. Fetal factors include color of the amnionic fluid, body weight, and sex. We examined the fundus of 161 newborn infants and investigated the above factors that influenced the retinal hemorrhages. The results were as follows: 1. The overall incidence of the retinal hemorrhages were 35.4%. 2. According to the delivery types, retinal hemorrhages were found in 57.9% after vacuum extraction, in 41.7% after induction delivery, in 33.8% after spontaneous delivery, and in 13.5% after Cesarean section. 3. As the duration of pregnancy increased in complicated delivery, retinal hemorrhages also tendted to increase. 4. The incidence of hemorrhages were greater in the hypertensive mother and abnormal color of amnionic fluid in spontaneous delivery. 5. The incidence of retinal hemorrhages were greater in the high body weight, multipara, and normal duration of labor. 6. Retinal hemorrhages were not related the maternal age and fetal sex. 7. Retinal hemorrhages were absorbed within four weeks.

We operated on 37 congenital cataract patients(bilateral 23, unilateral 14) from April, 1984 to April, 1986. The age of the patients at the time of their operation ranged from 2 months to 15 years old. The average age was 4.1 years old. The follow-up period ranged from 5 months to 6.3 years, the average being 2.2 years. We compared the incidence of strabismus according to unilaterality, the method of operation, the age at which the operation took place, and the correction of vision. All strabismic cases were exotropic. The strabismus occurred in 34% of all patients at the first examination and 65% at the final examination during follow-up period. The occurrence rates of the strabismus during the follow-up period were 22% in the bilateral cases, and 50% in the unilateral ones. This difference was statistically significant(p<0.05). According to the operation method, the strabismus occurred in 25% of I and A cases, but only 16% of lensectomy ones. This was also statistically signiIicant(p<0.05). The occurrence of strabismus had a statistically significant difference of 8% in operations before 3 years of age and 32% after 3 years. The occurrnce of stabismus was increased in cases of old age, after cataract, poor postoperative visual correction, and unilatral cases.

A 3-year-old girl with rapidly progressive proptosis had an unusual malignant germ cell tumor of the orbit identified as an endodermal sinus tumor. The endodermal sinus tumor is a malignant germ cell neoplasm that usually arises in gonads, but on rare ocassion ocurrs in extragonadal locations. Histologic examination revealed pseudo papillary pattern that on occasion created peculiar organoid structure similar to the glomeruli(Shiller-Dubal bodies). The patient was treated with exenteration of left orbit and three drug chemotherapy. The present case is of particular interest because of the rarity of extragonadal endodermal sinus tumor.

Nomal kittens showed a gradual increase from 17.6% to 25.5% of BLS with aging from the fifth week to the ninth. Young kittens showed significantly less BLS than adult ones(p<0.1). There was no significant difference in BLS between exotropic and nomal kittens or alternating and non-alternating strabismic ones. However, there was a significant difference in BLS between esotropic and nomal ones(p<0.1). These results suggested that the BLS can be used as an index for the extent of total field from both eyes.

A preliminary study was performed to investigate the staining characteristics of trabecula. endothelial cells with low density lipoprotein (LDL) and acetylated low density lipoprotein (Ac-LDL) labeled with a fluorescent probe, 1, 1`- dioctadecyl-3,3,3`, 3`- tetramethyl-indocarbocyanine perchlorate (Dil). Trabecular endothelial cells revealed a strong fluorescence with Dil-LDL, which was contradictory to the previous results obtained from other types of endothelial cells. These cells also showed a moderate fluorescence with Dil-Ac-LDL. Scleral fibroblasts and keratocytes showed a moderate to strong fluorescence with Dil-LDL and a weak fluorescence with Dil-Ac-LDL. Corneal endothelial cells revealed a very weak background fluorescence with Dil-LDL and a moderate fluorescence with Dil-Ar-LDL. Therefore, these four kinds of cells could not be definitely differentiated depending only on the staining characteristics with Dil-LDL and Dil-Ac-LDt.

Normal kittens showed a gradual increase from 17.6% to 25.5% of BLS with aging from the fifth week to the ninth. Young kittens showed significantly less BLS than do adult ones (p < 0.1), There was significant difference of BLS between exotropic and normal kittens or alternating and non-alternating strabismic ones. However, there was a significant diftrence between esotropic and normal ones (p < 0.1). These results suggested that the BLS can be used as a index for the extent of total field from both eyes.
