In this paper, course and complications of the 200 cases of cataract extractions and postoperative period as well as the visual acuity a t conclusion of period of observation are presented. The observation are made comparing with the types of corneo-scleral suture. The vision of preoperatively complicated cases are not so improved after successful cataract extraction. Vitreous loss during the operation and, vitreous protrusion into anterior chamber do not interfere thc post-operative vision. Massive and longstanding hyphema used to interfere the final vision. The average visual acuity after the operation revealed 0.34. All the above indicated observation are performed on the cases of average age 56.1 years old.

It has been known that ultraviolet B(UVB) light made an oxidative damage to lens proteins, lipids and nucleic acids to induce lens opacity. The aim of the study was to investigate the effect of bendazac lysine salt (Bendaline) tot the experimental cataract developed by UV irradiation. Forty rats were exposed to 0.1mW/cm2 of UVB radiation in the range 300-320 mm for 24 hours per day. Five control rats were not exposed UVB radiation. During the investigative period, we measured lens opacity with Scheimpflug camera every other week. Rats were divided into 9 groups according to the duration of UV radiation and initial time of bendazac lysine medication. Bendazac lysine was administered orally by 25mg/kg per day for 2 months. The opacities on anterior cortex, nucleus and posterior capsule began to appear 4 months after UVB irradiation. The longer duration of radiation, the more severe opacity of lens was observed, especially at the layers of posterior supranucleus, posterior cortex and posterior capsule and in the opacity area by retroillumination image. After UVB induced cataract was developed, the lens opacity was not changed nevertheless stop the UV irradiation. Lens opacity of bendazac lysine-treated groups was not severer than that of no medication groups. There were less opacities on 4 month irradiated group rather than 6 month irradiated group at the layers of nucleus and posterior cortex and in the opacity area. Anticataract action of bendazac lysine was effective in earlier cataract. In the group of bendazac lysine medication with UVB irradiation on same time, the prophylactic evidence of bendazac lysine was not observed.

The purpose of this study was to evaluate the parts of discrepancy on orthognathic surgical cases with skeletal Class III malocclusion. For this study, Ricketts' analysis that has suggested visual treatment objective, as named for growth predictable blue print, was used. The results of this study were as follows: 1. In the denture problem, mandibular incisor and molar was positioned more anteriorly in Class III malocclusion. 2. The location of A point was characteristically posteriorly positioned in the Class III group, and mandible plane angle was within normal range in the groups. 3. Position of upper and lower anterior teeth to A-Pogonion line was anteriorly positioned, and angulation of upper anterior tooth was lingually positioned in the Class III group, but angulation of lower anterior tooth was not significant in the both groups. 4. Esthetic line of Ricketts' analysis was not significant statistically. 5. Facial depth and axis was larger, but facial taper(facial plane mandible plane) was smaller in the Class III group. So, protruded and concave profile was seen in the Class III group. 6. Cranial deflection was larger in the Class III male group, ramus location was anteriorly positioned and mandibular length was enlarged in the male and female of Class III group.

Penetrating ocular injuries with intraretinal foreign body(IRFB) are increasing and may result in significant visual morbidity. We evaluated retrospectively 22 eyes of 22 patients who had undergone pars plana vitrectomy for removal of IRFB at Dong-a University Hospital from July 1990 to June 1996. The majority of patients were adult male(95.5%). The nature of all IRFB was magnetic property and the causes of injury were hammering and cutting work(77.3%). Preoperatively, eyes were complicated with vitreous hemorrhage and opacity(59.1%), traumatic cataract(45.%), retinal detachment(36.4%), and corneal opacity(22.7%). Postoperative complications included vitreous hemorrhage and opacity(36.4%), retinal detachment(22.7%), and proliferative vitreoretinopathy(18.2%). In our study, poor visual prognosis was obtained in cases of corneal entrance site, IRFB larger than 2mm in size, IRFB located posterior to equator and IRFB associated with retinal detachment.

Mitomycin C (MMC) is an antimetabolite, antibiotic which prevents the proliferation of fibroblast and fibrosis by inhibition of DNA-dependent RNA synthesis. It has been used to increase the success rate of filtering surgery. We performed trabeculectomy and peripheral iridectomy with 0.4 mg/ml MMC application for 3 minutes in poor prognostic glaucoma patient, 26 eyes of 24 patients from February 1992 to December 1994. The postoperative change of intraocular pressure (IOP) and complications were followed up from 3 to 30 months (mean 12.4 months). The preoperative and postoperative mean IOP after 24 months were 32.3 +/- 11.4 mmHg and 12.7 +/- 3.1 mmHg, respectively. The decrease rate of IOP was 60.7% and the success rate was 71.7%. The postoperative complications were 15 eyes including 5 eyes of shallow anterior chamber, 5 eyes of hyphema, 2 eyes of conjunctival wound leakage, one eye of bleb rupture, one eye of choroidal detachment, and one eye of cataract formation.

The epidemiologic study to evaluate the risk factors and types of cataract had been performed in 210 cataract patients and in 103 normal controls at Chang-Nyung District, Kyung-Nam Province, from September 1995 to April 1996, using the slitlamp biomicroscopy and Scheimpflug camera(EAS-1000, Nidek, Japan). All the patients were asked to fill out a questionnaire. The results obtained are as follows: 1. The most common type of cataract in Chang-Nyung District was nucleosclerotic opacity. 2. The dominant jobs were farmer and housewife. 3. The more sunlight exposure and heavy drinker were related to nucleosclerotic opacity and smoking habit also related to peripheral cortical opacity of lens. 4. The patients with diabetes mellitus were related with posterior subcapsular opacity ; those with arthritis related with nucleosclerotic opacity. 5. The patients with long-term use of herb medicine were related with peripheral cortical and nucleosclerotic opacity ; those with corticosteroid related with posterior subcapsular opacity. 6. There was no relationship between cataractogenesis and family history of cataract and parity in female. 7. The patients with nucleosclerotic opacity preferred grain and vegetables and those with posterior subcapsular opacity, fruit, meats and coffee. In conclusion, multi-factors are involved in the cataractogenesis including age, occupation, outdoor working hours, smoking, drinking habits, systemic disease, long-term used drug, family history, parity, favorite food, etc. Each factor is considered to be related to specific type of lens opacity.

The hydroxyapatite has been used as an orbital implant for reconstruction after enucleation or evisceration. It has been known to be a biocompatible and nontoxic implant with good fibrovascular ingrowth, few postoperative complications, excellent prosthesis motility, and good cosmesis. We performed 36 cases of hydroxyapatite implantation with enucleation or evisceration from July 1992 to August 1994. The mean follow-up period was 7.4 months(range, 4 to 13 months). There were nine cases of implant exposure. three cases of peg extrusion, three cases of superficial conjunctival wound dehiscence, and one case of granulation tissue overgrowth. There was no infection of implant. Improving the postoperative results and reducing the postoperative complications, it requires proper surgical techniques including the selection of adequate implant size and good doctor-patient relationship.

PURPOSE: To determine the MR and CT imaging findings of inflammatory pseudotumor of the extraorbital head and neck. MATERIALS AND METHODS: We reviewed the MR (n=10) and CT (n=9) imaging studies of 11 patients with this condition (M:F=5:6, age range: 35-75 years), analysing each case in terms of location, occupying space, signal intensity, intracranial involvement, degree of contrast enhancement and adjacent bone change. Follow-up images were obtained in nine cases, and the response of each patient to steroid treatment was reviewed. RESULTS: Lesions involved the masticator space (n=8), the buccal space (n=6), the nasopharynx (n=5), the paranasal sinus (n=4), the parapharyngeal space (n=3), the prevertebral space (n=2), the orbit (n=2), the carotid space (n=2), the paravertebral space (n=1), parotid space (n=1), and the oral cavity (n=1). In ten of eleven cases, there was adjacent bone change. In three cases, the cavernous sinus was involved, and in two, the dura. One case involved both of them. At T2-weighted imaging, the lesions showed hypointensity in nine of ten cases; in four of nine, signal intensity was markedly low, and in no case was it diffusely high. In five of nine cases, the mass decreased in size after steroid therapy. CONCLUSION: Inflammatory pseudotumor showed iso-to hypointensity at T2-weighted imaging. Lymphadenopathy was not apparent.

We present two cases of compression of the common hepatic duct by overriding of the right hepatic artery. One case is gall bladder, common hepatic duct stone and one case is right intrahepatic duct stone. We observed the compression of the common hepatic duct caused by overriding of the right hepatic artery in the both cases. The final diagnosis was made at operative fields. These patient were successfully treated by dissection of adhesion, suture, fixation between gall bladder bed and right hepatic artery.
