We evaluated the effectiveness of photoastigmatic refractive Keratectomy(PARK) by excimer laser on patients with compound myopic astigmatism. Spherocylindrical PARK was performed on 181 myopic eyes with astigmatism(mean spherical equivalent : -6.61 D, range : -1.88~-14.5 D) using the visx excimer laser. The eyes were divided into three groups according to the amount of desired astigmatic correction : Group 1(-0.5~-1.0 D), Group 2(-1.25~3.0 D), and Group 3(-3.25~-5.5 D). Patients were followed up for 6 months. Uncorrected visual acuity at postoperative 6 month, was 0.80+/-0.27 in Group 1, 0.79+/-0.19 and 0.71+/-0.21bin Group 2 and 3 respectively. The mean spherical equivalent refraction was -0.24 D 6 months after PARK. Mean astigmatism was reduced from preoperative -0.85+/-0.51 D to postoperative -0.34+/-0.38 D in Group 1, from -2.08+/-0.65 D to -0.43+/-0.64 D and from -4.42+/-0.63 D to -1.23+/-1.25 D in Group 2 and 3 respectively. We also analyzed the angle of error, magnitude of error, index of success, and coefficient of afjustment by vector analysis. No significant complications were observed during the follow-up period. These results show that PARK by excimer laser was effective in correction of astigmatism. The effect of astigmatic correction in Group 2 and 3 were better than that of Group 1. Group 1 showed overcorrected tendency and Group 2 and 3 showed undercorrected tendency.

We report a case of 17-year-old female with juvenile onset systemic lupus erythematosus Who developed symptomatic unilateral sacroiliitis. She had neither HLA-DR3 nir B27 antigens. Though sacroiliitis have been reported in mail SLE patient. it has been rarely reported in female patients. The rare coexistence of SLE and sacroiliitis. described in this case. may not be determined soley by genetic factors; sacroiliitis may be just an infrequent manifestation of SLE.

PURPOSE: To compare the surgical results of lacrimal surgery for nasolacrimal duct obstruction with and without canalicular stenosis. METHODS: We surveyed 175 eyes which underwent external dacryocystorhinostomy with silicone tube intubation from January 1996 through December 2000 retrospectively. Group 1 included 126 eyes in nasolacrimal duct obstruction without canalicular or commoon canalicular stenosis and group 2 included 47 eyes with canalicular or common canalicular stenosis. We checked the statistical significance with Chi-squre Test. RESULTS: Anatomical success rate was 96.0% (121/126) in group 1 and 85.7% (42/49) in group 2; It was statistically significant (p<0.05). And functional success rate was 91.3% (115/126) in group 1 and 73.5% (36/49) in group 2; it had statistic significance (p<0.05). The surgical success rate depending on the size of sac was not statstically significant in goup 1, but it had statstic significance in total group (p<0.05). In site of stenosis, anatomical and functional success rate ware 93.1% (27/29) and 79.37% (23/29) in common canalicular stenosis. It was higer surgical success rate than the other site, but it had no statistic significance. CONCLUSIONS: The canalicular or common canalicular stenosis is important factor in success of lacrimal surgery. Therefore it is recommendable to open the canalicular stenosis by probing prior to performing dacryocystorhinostomy.

The knee joint is one of the major weight bearing joint in the body, and is frequently injured because of its complex motion despite of a simple bony architecture. In the fracture of the tibial condyle the injuries of soft tissues such as ligaments and menisci are frectuently accompanied, and the weight bearing surface is involved. So it often produces a disability of the knee joint. Forty-seven consecutive cases of the tibial condylar fracture treated at the orthopaedic department of the Hallym Medical College from 1982 to 1985 have been analyzed according to its type, radiologic diagnosis, treatment, and end results. The conclusions are; 1. The tomography is important in the decision of the treatment method by the accurate measurement of the extent of depression and displacement. 2. The poor results are usually caused by a severe comminution and some associated injuries such as menisus tear, open wound, and rupture of ligamentum patellae etc. 3. The better results can be obtained with the treatment of early exercise within 6 weeks, of weight bearing between 12-20 weeks, and in surgical cases, within 2 weeks and with a bone graft.

A meniscal cyst is not common disease of knee joint. Many cases have been reported but its cause and origin are still pooly understood. We experienced two cases of the cysts on the lateral meniscus. They were treated by arthroscopic partial menisectomy and extraarticular excision of the cyst. The good results were obtained.
