Axenfeld-Rieger syndrome is a rare autosomal dominant disorder characterized by various ocular and extraocular malformations. The incidence of Axenfeld-Rieger syndrome has been estimated to be 1 per 200,000. The syndrome is characterized by short body stature, delayed bone age, and deficient or arrested development of neural crest cells involving the anterior chamber of the eyes, facial bones, teeth, periumbilical skin, and cardiovascular system. This is a case of a 6 year-old girl, who came to the department of the pediatric dentistry, Yonsei University Dental Hospital, for evaluation and treatment of multiple congenital missing permanent teeth. The patient presented typical dental, craniofacial, and systemic features of Axenfeld-Rieger syndrome, such as glaucoma, oval pupil, heterochromatic iris, umbilical hernia, and delayed bone age. On the panoramic view, 3 primary teeth were missing and 13 permanent tooth germs were absent. On the lateral cephalograph, underdevelopment of the maxilla and normal growth pattern of the mandible were confirmed. Periodic dental follow-up is planned for evaluation and interceptive treatment of her dental and craniofacial problems. Denture or removable space maintainer with a pontic is considered for esthetic and functional restoration. In addition, orthognathic surgery is also planned in future to prevent further midfacial skeletal deformation. Early diagnosis of Axenfeld-Rieger syndrome is very important to prevent exacerbation of complications, such as glaucoma and skeletal deformities.
Myasthenia gravis is a neuromuscular transmission function disorder characterized by fatigue and weakness of voluntary muscles. This muscular weakness is intensified by activity and stress, and improved by the use of anticholinesterase compounds. It was initially described by Erb in 1879 and later named myasthenia gravis by Jolly in 1895. Although the pathogenesis is Known to be an autoimmune related reduction in the number of available acetylcholine receptors at neuromuscular junctions, the role of thymus in myasthenia gravis is still unclear and under investigation. Thymectomy in the management of myasthenia gravis has become increasingly important since Dr. Blalock observed in 1939 that some patients with thymic tumors and myasthenia gravis improved following thymectomy. A clinical study of 102 cases of myasthenia gravis was performed at Yonsei University College of Medicine. Seoul, Korea from Jan. 1976 to Jun. 1986. In order to determine which factors are of prognostic significance, attention is focused upon pre-operative patient evaluation, problems in operative and post-operative care, and long-term follow-up observations. The results were as follows: 1. The sex distribution was 67 females and 35 males, the mean age of onset was 28.95*1.69 years, and the maximal incidence occurred between 21 and 40 years of age [56 cases: 54.9%]. 2. Clinical manifestations of ocular symptoms were seen to 70 patients [68.6%] extremities weakness in 33 [32.3%], bulbar weakness in 29 [28.4%], and dyspnea in 13 [12.7%]. 3. Study cases more than two thirds were classified as mild types [MG 1 and MG 11A] and 6 cases as grave [MG 1V] based on the modified Osserman`s classification system, 4. Thymectomy was performed in 19 cases which presented in severe myasthenia symptoms and showed no improvement with cholinergic drugs. Histologic examination of the excised thymus glands revealed no abnormalities in 4 cases, thymic hyperplasia in 5, benign thymoma in 5, and malignant thymoma in 5. 5. Immediate post-operative complications included 2 cases of pneumothorax which were treated by tube thoracostomies, there was no operative mortality. 6. The response to cholinergic drugs in 36 cases younger than 20 years old and in 27 cases older than 40 years was relatively poor, while that in 35 cases between the ages of 21 and 40 years old was good. 7. Thirty of 39 cases in groups IIB, III & IV improved markedly with medical or surgical management while only 16 of 59 cases in the mild groups [I and IIA] improved, almost all surgical cases improved in all categories. 8. There were 5 deaths. occurring between 7 months and 3 years 3 months of treatment of myasthenia gravis. The causes of death were myasthenic crisis in 2 cases, respiratory failure due to candidiasis & radiation pneumonitis in one case, cerebral hemorrhage due to high blood pressure in two case.
Purpose: Previously reported ocular complications of interferon alfa administration are extremely rare. We experienced a 15-year-old boy with chronic hepatitis B who developed glaucoma after interferon alfa therapy. The purpose of this prospective study was to evaluate the possible development of glaucoma after interferon alfa therapy for chronic hepatitis B. Methods: Nine patients with chronic hepatitis B who visited Inha university hospital between February 1998 and July 1999 received interferon alfa therapy. We measured visual acuity, intraocular pressure, C/D ratio, and visual field examination at pre-interferon therapy, three and six months after therapy, respectively. Results: The total number of patients was 9 (4 boys and 5 girls). Mean age was $11.7{\pm}4.1$ years. The duration of therapy was 6 months and mean dosage of interferon was 5 million units. Compared with visual acuity, intraocular pressure, and C/D ratio at pre-therapy, those parameters at 3 months and 6 months after therapy showed no significant differences and none showed visual field defect after therapy. Conclusion: Our prospective study showed no evidence of development of glaucoma after interferon therapy. However, it is necessary to be concerned about the possibility of developing glaucoma or other ophthalmologic diseases after interferon therapy in chronic hepatitis B.

Purpose: There are many reports about facial bone fractures, but limited to retrospective data of a single hospital. Etiology and severity of the facial bone fracture have been changed and treatment method and materials have been advanced. In order to reflect those changes and provide up-to-date data of the facial bone fractures in Daegu, we gathered the data and analyzed the epidemiologic study. Methods: The medical records of 1058 fractures in 895 patients were gathered from 5 general hospitals in Daegu during last year and these data were analyzed by following parameters: age, sex, place of residence, occupation, cause of injury, time of injury, location of fracture, length of in-hospital stay, time of operation, treatment method, associated injury, complication. Statistical analysis was performed using the Chi-square test. Results: Most commonly involved age group was 20s(26%) and the sex ratio was 3.4:1(male predominance). Fractures were occurred more in unban and white-color workers. Among variable etiology of injury, traffic accident was the most common cause. Time of injury was heighest at 6 to 7 P.M., on Sunday, in July. Locations of fractures were following sequence: nasal, zygoma, mandible, orbit, maxilla. Mean length of in-hospital stay and time of operation after injury were 6.3 and 3.2 days, respectively. In treatment methods, operative methods were dominant than conservative management and general anesthesia were favored than local anesthesia. Associated injuries were noticed in 188 cases(21.2%) and complications were in 94 cases(8.9%) and among them, ocular problem were common. Conclusion: Compared to previous studies, mean age of occurrence was lowered and the etiologies showed age-specific pattern and reflected the change of lifestyle. In young age groups, sports injury, violence were more dominant and the other hand, traffic accident and fall were dominant in older groups.

An 8-year-old male dog weighing 7.9 kg was referred to us for evaluation of exophthalmos and corneal edema of the left eye, on which cataract surgery had been performed 3 years prior. On ophthalmic examination, the left eye showed an extremely high intraocular pressure (47 mmHg), with no menace response, dazzle reflex, or pupillary light reflex. The dog was treated with systemic and topical glaucoma medications. After treatment, corneal edema decreased but IOP did not return to within acceptable limits. Seventeen months later, the dog presented with hyphema, episcleral congestion, and corneal edema attributable to accidental trauma. The owner wished to maintain an attractive ocular appearance, and an intraocular silicone prosthesis (ISP) was thus inserted after the evisceration. Three months postoperatively, a corneal ulcer was detected, but this resolved successfully after prescription of appropriate medication. One year after surgery, no complications related to surgery were evident.

According to the change of mandatory referral system in July 1, 2000, the effect to the medical utilization of outpatient clinic and medical income in ophthalmology of tertiary care medical institute, S Hospital in Seoul was evaluated for 6 months before(1999. 12$\sim$2000. 5) and after(2000. 12$\sim$2001. 5). The results were as follows: 1. The number of outpatients was reduced by 16.6%. The number of patient with blindness low vision, retina, glaucoma increased and that of patient with accommodation refractive error, cataract decreased. 2. The number of cataract patients was reduced by 36.6%. The major location of patient's address was changed to nearer to the hospital. The number of cataract surgery reduced in 4.1%, the waiting time reduced in 42.2%, however surgery time increased in 20.2% and number of postoperative complications increased in 11.4%. 3. The income of outpatient clinic and cataract surgery reduced. Among items of outpatient clinic income, the most increased was ocular examination and the most reduced was injection and drugs. Among items of cataract surgery income, the most increased was operation fee and the most decreased was doctor's fee. In conclusion, for the patient, due to the lowered density of outpatient population more space was provided to the patients with more severe disease entity such as blindness' low vision, retina and glaucoma. For the hospital, the need for the expansion of ophthalmology was not found, however that for creation of the special clinics dealing with more severe disease entity was found. Due to reduced income and increased need of financial investment for the equipment and manpower for the more severe disease entity, the ophthalmology of tertiary care medical institute is faced with financial disaster. It is strongly suggested that the cost of medical practice of more severe disease entity be raised to achieve the success after change of mandatory referral system in ophthalmology.

A 13-year-old, female, Shih-tzu and a 10-year-old, female, Yorkshire terrier were presented with ulcerative keratitis caused by corneal endothelial degeneration. Generalized corneal edema, conjunctival hyperemia, focal corneal pigmentation, corneal neovascularization, sub-epithelial bullae, and positive fluorescein staining were observed during ophthalmic examinations. Thermokeratoplasty was performed on the overall edematous corneas. Healing of the cornea was completed within 25 days and corneal ulceration has not recurred after healing of the cornea in both cases. Other ocular complications were not observed except for a slight increase in corneal pigmentation. According to this study, thermokeratoplasty could be an effective treatment for corneal ulceration secondary to corneal endothelial diseases in dogs.

One of the major ocular complications of diabetes mellitus(DM) is retinopathy, which is characterized by increased neovascularization and neural degeneration in the retina. In the present study, we investigated the effects of treadmill exercise on retinopathy in the rats with DM. Thirty-two male Sprague-Dawley rats were divided into four groups(n = 8 in each group): control group, exercise group, DM-induction group, and DM-induction and exercise group. DM was induced by intraperitoneal injection of streptozotocin. The rats in the exercise groups were made to run on the treadmill for 30 min five times per a week, during 12 weeks. The expressions of phosphoinositide 3-kinase(PI3K), phospho-protein kinase B(pAkt), hypoxia inducible factor-1α(HIF-1α), and vascular endothelial growth factor(VEGF) in the retina were determined using western blot analysis and immunohistochemistry. In the present results, the expressions of PI3K, pAkt, HIF-1α, and VEGF in the retina of the diabetic rats were increased. Treadmill exercise suppressed HIF-1α and VEGF expressions through inhibition of PI3K/pAkt pathway in the diabetic rats. These results suggest that treadmill exercise may ameliorate the progression of diabetes-induced retinopathy by inhibiting neovascularization in the retina.

Background : The prone position is often used for operations involving the spine and provides excellent surgical access. The complications associated with the prone position include ocular and auricular injuries, and musculoskeletal injuries. In particular, the prone position during general anesthesia causes hemodynamic changes. To evaluate the cardiovascular effects of the prone position in surgical patients during general anesthesia, we investigated the effects on hemodynamic change of the prone position with the Jackson spinal surgery table. Materials and Methods : Thirty patients undergoing spine surgery in the prone position were randomly selected. After induction of general anesthesia, intra-arterial and central venous pressures (CVP) were monitored and cardiac output was measured by $NICO^{(R)}$. We measured stroke volume, cardiac index, cardiac output, mean arterial pressure, heart rate, CVP and systemic vascular resistance (SVR) before changing the position. The same measurements were performed after changing to the prone position with the patient on the Jackson spinal surgery table. Results : In the prone position, there was a significant reduction in stroke volume, cardiac index and cardiac output. The heart rate, mean arterial pressure and CVP were also decreased in the prone position but not significantly. However, the SVR was increased significantly. Conclusion : The degree of a reduced cardiac index was less on the Jackson spinal surgery table than other conditions of the prone position. The reduced epidural pressure caused by free abdominal movement may decrease intraoperative blood loss. Therefore, the Jackson spinal surgery table provides a convenient and stable method for maintaining patients in the prone position during spinal surgery.
