PURPOSE: To prospectively evaluate the clinical results of iris-fixed phakic intraocular lens (IOL) implantation (Artisan(R) implantation) in patients with high myopia. METHODS: Eighteen eyes of 10 patients underwent Artisan(R) implantation between December 2001 and February 2003 and were followed up for more than 6 months. The study prospectively analyzed the efficacy, safety and predictability of Artisan(R) implantation based on visual acuity and refractive errors. RESULTS: The preoperative mean uncorrected visual acuity (UCVA) was 0.02, and mean spherical equivalent refraction was -9.98D. Postoperative uncorrected vision was more than 0.5 in 83.3% of the eyes at 1 month and in 100% after 3 months. Also it was more than 0.9 in 22.2% of the eyes at 1 month, in 50.0% at 3 months and in 88.9% at 6 months. The spherical equivalent refraction after surgery was within 0.5D of emmetropia in 77.8% of eyes at 1 month, in 94.4% at 3 months and in 100% at 6 months. Also it was within 1.0D of emmetropia in 94.4% at 1 month and in 100% after 3 months. Complications included temporary glare or halo in 3 eyes, transient elevation of intraocular pressure in 1 eye, and decentration of IOL due to incomplete iris-fixation in 1 eye. CONCLUSIONS: Because of its good visual results and rare complications, the Artisan(R) implantation may be an effective surgical procedure for patients who cannot undergo laser in situ keratomileusis (LASIK).

PURPOSE: The authors report their experience with four cases of paralytic exotropia from a pit viper snakebite, accompanied with a literature review. METHODS: Four patients (two males and two females) visited the emergency room in the hospital with symptoms including diplopia, limitation of eye movement, exotropia, and blepharoptosis, after being bitten by a presumed pit viper, and were treated by antivenom. RESULTS: No visual disturbance was observed in the first examination, while limitation of adduction was found in four cases in the ocular movement test. As to the type of tropia, three patients showed intermittent exotropia and the other showed exotropia. The angle of strabismus in the distance was 20~30 prism diopters (PD) while that in the near was 18~35 PD. Two cases were accompanied with blepharoptosis. Except one case which was unavailable for follow-up observation, three cases became normal in diplopia, blepharoptosis, and limitation of ocular movement between the 4th and 11th day after the snakebite. CONCLUSIONS: Neurotoxicity induced by a pit viper snakebite is rare. However, neurotoxicity including strabismus and blepharoptosis can occur because extraocular muscles have a higher ratio of nerve fibers to the extraocular muscle fibers compared with skeletal muscles.

Leiomyoma is a tumor rarely occurring in the nose and the paranasal sinus. It constitutes about 1% of all benign tumors arising in the head and neck area. This is probably due to the paucity of smooth muscle in the nose. We experienced a case of leiomyoma originating in the right side of the nasal septum in a 50-year- man. It was successfully removed by endoscopic surgery, and we report this case with literature.

PURPOSE: The aim of this study was to evaluate alterations of papilla dimensions after orthodontic closure of the diastema between maxillary central incisors. METHODS: Sixty patients who had a visible diastema between maxillary central incisors that had been closed by orthodontic approximation were selected for this study. Various papilla dimensions were assessed on clinical photographs and study models before the orthodontic treatment and at the follow-up examination after closure of the diastema. Influences of the variables assessed before orthodontic treatment on the alterations of papilla height (PH) and papilla base thickness (PBT) were evaluated by univariate regression analysis. To analyze potential influences of the 3-dimensional papilla dimensions before orthodontic treatment on the alterations of PH and PBT, a multiple regression model was formulated including the 3-dimensional papilla dimensions as predictor variables. RESULTS: On average, PH decreased by 0.80 mm and PBT increased after orthodontic closure of the diastema (P<0.01). Univariate regression analysis revealed that the PH (P=0.002) and PBT (P=0.047) before orthodontic treatment influenced the alteration of PH. With respect to the alteration of PBT, the diastema width (P=0.045) and PBT (P=0.000) were found to be influential factors. PBT before the orthodontic treatment significantly influenced the alteration of PBT in the multiple regression model. CONCLUSIONS: PH decreased but PBT increased after orthodontic closure of the diastema. The papilla dimensions before orthodontic treatment influenced the alterations of PH and PBT after closure of the diastema. The PBT increased more when the diastema width before the orthodontic treatment was larger.

PURPOSE: There have been no reports of optic nerve injuries caused by gunshot in Korea. We describe such an injury and report the treatment outcomes. CASE SUMMARY: A patient visited our hospital complaining of visual disturbance after her right zygomatic bone had been shot with an airgun during a suicide attempt in September 2006. A visual acuity test, pupillary light reflex test, fundus examination, skull X-ray, and computed tomography (CT) were performed. At the initial examination, the right eye had no light perception. The pupillary light reflex test revealed an afferent pupillary defect, and the fundus examination showed central retinal artery occlusion. The skull X-ray and computed tomography revealed a fracture of the right medial and lateral orbital walls as well as a partial injury to the medial rectus muscle. In addition, right retrobulbar hemorrhage and metallic foreign bodies were observed in the right orbit. Under general anesthesia, disinsertion of the superior and lateral rectus muscles was performed, and the metallic foreign bodies in the right orbit were removed. The surgical incision was then closed. A Krimsky prism test performed 7 days after surgery revealed an approximately 15 prism diopters of exodeviation of the right eye. CONCLUSIONS: We report a case of optic nerve injury caused by a gunshot.

Isolated noncompaction of the ventricular myocardium (INVM) is a rare cardiomyopathy resulting from a failure of normal endomyocardial embryogenesis and it has been categorized as a form of unclassified cardiomyopathy. The disorder is characterized by an excessively prominent trabecular meshwork with deep intertrabecular recesses. Although the disorder is sporadic, familial incidence may occur. Clinical symptoms and prognosis of INVM may differ markedly, and range from an asymptomatic course to a severe cardiac disability. The diagnostic method of choice for IVNM is echocardiography, which reveals multiple prominent trabeculations with deep intertrabecular spaces communicating with the left ventricular cavity in the middle and apical segments of the left ventricle. The authors report a case of INVM in a family in which three adult members (a brother and two sisters) were found to be affected by this disorder. They were all asymptomatic. The diagnosis of the disorder was made first in the 36-year-old brother by transthoracic echocardiography (TTE) and multidetector CT (MD CT), during the process of preoperative evaluation for surgical treatment of low back intervertebral herniated disc. TTE and MD CT showed similar and peculiar findings of INVM. Echocardiographic screening in all first-degree relatives of this patient, in order to identify asymptomatic patients, demonstrated INVM in two elder sisters.

OBJECTIVE: The purpose of this study was to evaluate the efficacy of a transforaminal suprapedicular approach, semi-rigid flexible curved probe, and 3-dimensional reconstruction computed tomography (3D-CT) with discogram in the endoscopic treatment of non-contained lumbar disc herniations. METHODS: The subjects were 153 patients with difficult, non-contained lumbar disc herniations undergoing endoscopic treatment. The types of herniation were as follows : extraforaminal, 17 patients; foraminal, 21 patients; high grade migration, 59 patients; and high canal compromise, 56 patients. To overcome the difficulties in endoscopic treatment, the anatomic structures were analyzed by 3D reconstruction CT and the high grade disc was extracted using a semi-rigid flexible curved probe and a transforaminal suprapedicular approach. RESULTS: The mean follow-up was 18.3 months. The mean visual analogue scale (VAS) of the patients prior to surgery was 9.48, and the mean postoperative VAS was 1.63. According to Macnab's criteria, 145 patients had excellent and good results, and thus satisfactory results were obtained in 94.77% cases. CONCLUSION: In a posterolateral endoscopic lumbar discectomy, the difficult, non-contained disc is considered to be the most important factor impeding the success of surgery. By applying a semi-rigid flexible curved probe and using a transforaminal suprapedicular approach, good surgical results can be obtained, even in high grade, non-contained disc herniations.

PURPOSE: Here, we report a case of an infant with fetal alcohol syndrome with esotropia who was born to a mother who consumed a large quantity of alcohol during her pregnancy. METHODS: A 1-year-old female infant visited our hospital for the main symptom of the esodeviation of the eye. The medical history of the mother and the delivery history were reviewed, and a physical examination and ophthalmic examination of the infant were performed. RESULTS: At the first examination, the patient was 15 months old, her mass was 5, 600 grams, her height was 70 cm, her head circumference was 39.5 cm, and her chest circumference was 41 cm; all the measurements were below the 3rd percentile. From the gestation age of 24 weeks, the mother consumed 1-2 bottles of sojoo every day, and the infant patient was delivered at the gestation age of 42 weeks by Cesarean section. The infant's birth weight was 1, 510 grams. Upon physical examination, her philtrum was found to be shallow, and microcephaly was detected. Upon ophthalmic examination, a refractive error +1.25 Dsph. was detected. With regard to the horizontal length of the palpebral fissure, the right and the left were 1.7 cm and 1.6 cm, respectively, which is considered short; telecanthus and esotropia were also present. CONCLUSIONS: To the best of our knowledge, this is the first reported case of fetal alcohol syndrome with accompanying esotropia.

Postoperative pancreatic fistula (POPF) combined with postoperative fluid collection, bleeding and abscess formation is one of the most critical morbidities after distal pancreatectomy or pancreaticoduodenectomy. Percutaneous catheter drainage has been commonly used for managing for the postoperative management of abnormal fluid collection. Removal of the catheter is rarely associated with occurrence of life-threatening complication such as serious liver damage. Herein, we report a case of unexpected fatal liver injury complicated by percutaneous catheter drainage treatment after distal pancreatosplenectomy in a patient with pancreatic cancer. We suggest that prudent decision for timing of catheter removal and meticulous care during procedure can reduce the possibility of major liver injury in patients with percutaneous transhepatic catheter drainage.
