Here, we report 3 cases of mixed tumor of the lacrimal gland. The age of the patients were 43, 26 and 35 respectively. The two of these were male and one female. The most outstanding complaint was exopthalmos. A mass was palpated on the orbit and eye ball deviation in downward position was present in all cases. Pathologic findings were mixed tumor of the lacrimal gland with no evidence of malignancy. These tumors were well encapsulated and any evidence of involving bone and soft tissue was not found. Modified Kroenlein-Berke operation was performed and tumor mass was removed entirely with finger dissection in all cases. The vision was not improved but the cosmetic result was satisfactorr.

There were many instances in which glaucoma, esp. primary, combined with hearing disturbance. The etiology of these cases has not been known until now. We had 15 primary glaucoma patients for whom pure tone audiometry wa~ performed, and could find the hearing defect in high tone in 5 cases (1/3 among those patients). The audiometric curve was similar to that in the presbycusis, but severer in degree than that occured within the normal physiological aging process. The average age was 62.4 year in the group with the hearing defect, and 45.6 year in the group without the hearing defect. There were no relationship between the hearing defect and intraocular tension, visual field change, glaucomatous cupping, and duration of glaucoma. These results may support the opinion of the authors that the hearing disturbance in glaucomatous patients is related to the arterioscIerotic changes which aggrevate the presbycusis, and not related to glaucoma itself. On the otherhand, however, it is stilI impossible for us to rule out that the pleiotropic and multifactorial genetic factors may play as a common important role in the hearing disturbances and glaucoma. And further studies would be necessary for these problems.

The primary overaction of the inferior oblique(IO) muscle is of unknown cause, whereas the secondary overaction of IO is usually related to the palsy of the ipsilateral superior oblique or contralateral superior rectus. To understand the cause of the primary overaction of the IO, an ultrastructural study on primary and secondary overacting IO muscles was performed by electron microscopy. The most striking abnormalities were aggregations of mitochondria, degeneration of mitochondrial profiles, and increased vacuolization in primary and secondary overacting muscles. These changes were more severe in cases of primary overaction thitn in those of secondary overaction. Many muscle fibers were in different stages of atrophy. Hypertrophy and regeneration of muscle fibers were sometimes visible. The primary and the secondary overacting IO muscles showed similar morphologic alterations. These results suggest that the primary overacting IO muscle might be the result of a paresis of the superior oblique muscle.

A case of Mooren's ulcer in a 68 years old korean female has been reported. This is a rare disease and hitherto it is not reported in Korea. A brief review of litera tures has also been described.

Overaction of the inferior oblique(IO) muscle is manifested by elevation of the adducted eye and from the clinical point of view there are two types of overaction. The primary type is of unknown cause, whereas the secondary type is usually related to the palsy of the ipsilateral superior oblique or contralateral superior rectus. An ultrastructural study on the overacting IO muscles was performed compared to normal IO muscles by electron microscopy. Of 16 biopsies of overacting IO muscles, four had primary overacting inferior obliques and twelve had secondary overacting inferior obliques due to paralysis of superior oblique muscle. Additional four IO muscle, obtained from patients with intraocular diseases served as control specimens. The most striking abnormalities were aggregations of mitochondria and degenerating mitochondrial profiles and increased vacuolization in primary and secondary overacting muscles. Many muscle fibers were in different stages of atrophy, and hypertrophy and regeneration of muscle fibers were sometimes visible. The results suggest that the primary overacting IO muscle might be the result of a paresis of the superior oblique muscle.

From May to October 1987, 32 patients of diabetic retinopathy were studied with visual acuity, Farnsworth-Munsell 100-hue test, urine glucose test, standard fundus color photography, and fluorescein angiography to assess the type and extent of color vision defect associated with diabetic retinopathy, mainly nonproliferative, and the presence of macular edema. Nine patients showed significantly higher error scores in Farnsworth-Munsell 100-hue test than expected in non-diabetic individuals and tendency of a tritan axis. Eyes with macular edema showed higher Farnsworth-Munsell 100-hue scores than those without macular edema, but the differences were insignificant. Only one patient made an error in reading of urine glucose test by himself.

The delayed adjustable strabismus surgery may be desirable because the angle of strabismus can be changed after the strabismus surgery. We have studied the effect of 2% cyclosporin A on the delayed adjustable strabismus surgery in rabbits. Two percent cyclosporin A was soaked for 5 minutes for group 4 and 10 minutes for group 5 between the conjunctiva and sclera during the adjustable strabismus surgery on the eyes of New Zealand white rabbits. The eyes in group 1 received only adjustable strabismus surgery, and those in group 2 and 3 received the surgery including 5 minutes and 10 minutes soaking with castor oil, respectively. We evaluated the time of adjustability and measured the traction force and length during adjustment after the adjustable strabismus surgery. We could adjust in all of the 6 eyes in group 4 and 5 two weeks after the surgery. At 1 week, the traction forces were 30.7+/-14.0 (mean+/-SD), 42.0+/-39.6, 31.7+/-7.5, 24.0+/-7.5, and 21.8+/-6.0 gm in group 1, 2, 3, 4, and 5, respectively. The forces in group 4 and 5 were not significantly different from those in group 1, 2, and 3. At 2 weeks, the degrees of adhesion between the conjunctiva and superior rectus muscle, and those between the muscle and sclera were significantly lower in group 4 and 5 than those in group 1, 2, and 3. These results suggest that 2% cyclosporin A soaking is useful to obtain the better results due to the delayed adjustment by decreasing the adhesion around the muscle (J KoreanOphthalmol Soc 41:2115~2123, 2000).
