ABSTRACT
Cycloplegic refraction with 1% cyclopentolate and I % atropine was performed in esotropic children younger than 6 years. The purpose of this study was to find clinical factors related with differencs in refractive changes between cyclopentolate and atropine Additionally, the periodic refractive changes at the first, second and third day during performing traditional atropinization were evaluated. The results were as follows: The refractive state after using 1 % cyclopentolate was + 5.00 diopters in average and that after using 1% atropine was +5.77 diopters in average (pSubject(s)

ABSTRACT
Contrast sensitivity was measured by MCT 8000(R)(Vistech Consultant INC, U.S.A.) in two groups: 23 strabismic amblyopes and 10 anisometropic amblyopes. In general, the amblyopic eyes exhibited a statistically significant loss of contrast sensitivty in both day and night vision. When visual acuity was equated between groups, the anisometropic group had a greater loss of contrast sensitivity at the high spatiaI frequencies and the strabismic group exchibited a similar loss of contrast at all spatial frequencies. Test-retest correlations(average 0.76) were statistically significant, which demonstrated that the test using MCT 8000(R) was reliable.

Fibrous histiocytomas are complex group of tumors that feature cells resembling fibroblasts and histiocytes and that exhibit a cellular arrangement referred to as a storiform or cartwheel pattern. A 36 year old man was referred to our hospital with 2 months history of protruding mass in his right eye. Mass excision was performed and histopathologic examination including immunohistochemical stainning revealed malignant fibrous histiocytoma and he received radiation therapy.

The authors performed frontalis suspension using palmaris longus tendon in 3 patients, 2 with congenital blepharoptosis and 1 with acquired blepharoptosis. Good results without any complication as undercorrection, overcorrection, irregular lid magin, ectropion were obtained for 5 to 11 months of follow up check.

The authors experienced a case of oculo-auricular dysplasia(Goldenhar's syndrome). Goldenhar's syndrome is a rare congenital disorder, which is characterized by epibulbar dennoid, preauricular appendage and pretragal blind fistula. The patient was 4-year-old boy who had epibulbar dermoid, preauricular appendage, small facial bone, small mandible and hypoplastic maxillary sinuses. In addition to above mention, we reviewed the several literatures about this syndrome.

Hand-Schuller-Christian disease, eosinophilic granuloma and Letterer-Siwe disease are classified as histiocytosis-x, on the basis of the underlying proliferation of histiocytes in all three conditions and of their indefinite etiology. The authors experienced a case of Hand-Schuller-Christian disease with exophthalmos. A 17 months old boy was admitted to our Dept. of Ophthalmology because of left exophthalmos since 2 months ago. A biopsy demonstrated that the lesion was Hand-Schuller-Christian disease. The patient was treated with chemotherapy and low dose radiation therapy. We report our experience with this patient along with the review of other papers in this report.

To evaluate the short term effects of antibiotics on corneal endothelium, we injected relatively high dosage of antibiotics into the anterior chamber. The experimental dosages of antibiotics used were 4,000 ug of gentamicin, 4,000 ug of amikin, 3,300 ug of cefamezin and 3,300 ug of kedacillin. The effects of these antibiotics on the rabbit corneal endothelial structure and function were evaluated by using ultrasonic pachometer, specular microscope, trypan blue vital staining and electron microscope at 3 hours, 2 days and 7 days following the intracameral injection. For this study 16 rabbits were used for histologic examination and 14 rabbits were used for measuring corneal thickness and endothelial density. The results were as follows: 1. There were no meaningful increases in corneal thickness at 3 hours after intracameral injection of the four antibiotics. However, at 2 days after intracameral injections, the four antibiotics affected significant increases in corneal thickness, i.e., gentamicin, 21 um, amikin, 14 um, cefamezin, 21 um, and kedacillin, 20 um. And at 7 days after the intra cameral injections, the increases of corneal thickness were gentamicin, 20 um, amikin, 18 um, cefamezin, 27 um, and kedacillin, 25 um and these differences were significant statistically. 2. The degrees of corneal thickness change with time lapse after intracameral injection of various antibiotics were as follows: a) from 3 hours to 2 days: gentamicin, 20 um, amikin, 12 um, kedacillin, 14 um, cefamezin 12 um. b) from 2 days to 7 days: gentamicin. -1 um, amikin, 4 um, cefamezin, 6 um, kedacillin, 5 um. The above results showed larger increments in 3 hours to 2 day changes than in 2 to 7 day changes. 3. There were no meaningful decreases in corneal endothelial density at 3 hours, 2 days and 7 days after injection of gentamicin, amikin and kedacillin compared to preintracameral injection values. However in the case of cefamezin, there was a significant descrease of 1.9% in endothelial density at 7 days after injection compared to preintracameral injection value. 4. No meaningful differences were found in trypan blue vital staining and flat preparation between the antibiotics. In the case of trypan blue vital staining, average of 16.5% of endothelial cells stained with trypan blue at 3 hours after intracameral injections, and less than 10% of endothelial cells were stained at 2 days and 7 days after intracameral injections. Flat preparations showed edematous change of endothelial cells at 2 days after intracameral injection of antibiotics. 5. In transmission electron microscope studies, similarities were found in the ultrastructural change between the antibiotics. At 2 days following intracameral injection, affected cells showed some detectable cellular edema with minimal dilatation of the endoplasmic reticulum and minimal swelling to the mitochondria. In view of the above results, increase of corneal thickness and cellular edema were found at 2 days after intracameral injection of gentamicin 4,000 ug, amikin, 4,000 ug, cefamezin 3,300 ug and kedacillin 3,300 ug. Howeveer we could find out that the function and structural change of corneal endothelium returned to normal condition at 7 days after intracameral injections and that the endothelium can tolerate relatively high dosage of antibiotics.
