In order to study the development of fungal keratitis in wearing of the soft contact lenses contaminated with fungus in various conditions of the cornea, we contaminated the soft contact lenses with Candida albicans, and then placed them on the corneas in rabbits. The rabbits were divided into 4 groups(each 8 eyes). In group 1, dexamethasone was injected subconjunctivally once a day for 4 days and the corneal epithelium was removed 7mm in diameter. In group 2, dexamethasone was injected subconjunctivally once a day for 4 days without removal of the corneal epithelium. In group 3, the corneal epithelium was removed 7mm in diameter without subconjunctival injection of dexamethasone. In group 4, normal corneas were used as a control. The corneas were observed daily with slit-lamp. After 10 days, the infected corneas were examined with light microscope. Keratitis was developed in 5 eyes in group 1(5/8), 3 eyes in group 2(3/8), 2 eyes in group 3(2/8). But keratitis was not developed in group 4. Light microscopic examination showed active invasion of C, albicans forming pseudohyphae into the cornea associated with severe inflammation in group 1 and 2, but it showed mild inflammation and only a small number of C, albicans in the superficial cornea in group 3. In this study, it was found that immunosuppressed and de-epithelialized corneas are susceptible to C, albicans.

We inspected reliability of A-constant of AMO SI-30NB by comparing target diopter and actual postoperative refractive status. Group 1 comprised 191 eyes which were implanted AMO PhacoFlex SI-30NB with corneal incision. Group 2 comprised 45 eyes implanted Pharmacia 812C with scleral incisions. Group 3 comprised 17 eyes implanted AMO OgaciFlex SI-30NB with corneal incision. Refraction was performed on post operative day 1, day 5, day 14, 1 month, and 3 month. It revealed hyperopic shift of 0.31 to 0.40 diopter compared to the target diopters in both Group 1 and Group 3 and no statistical difference was found between two groups(p value>0.05). On the other hand, Group 2 were statistically significant(p value<0.01). We attempted mathematical modelling of this phenomenon and the cause of hyperopylene haptics, structural weakness of haptic-optic junction, and the structure of SI-30NB itself.

PURPOSE: To objectively define the degree of cupping, the authors extracted 3-dimensional slope surface maps from Cirrus HDTM-OCT data and assessed their differentiating characteristics between normal subjects and glaucomatous patients. METHODS: One eye from each of 40 normal subjects and 1 eye from each of 39 patients with glaucoma were examined using automated visual field perimetry and Cirrus HDTM-OCT. The Optic Disc Cube 200 x 200 protocol was performed. The individual OCT data were reconstructed as the 3-dimensional surface maps of the optic disc cup and the slope of each contour was calculated using custom-developed software. Several disc cup slope parameters were derived. The parameters measuring the internal features of the optic disc cup were calculated and compared between groups. RESULTS: Sum of cup slope, sum of thresholded cup slope, and sum of thresholded cup slope / thresholded cup area parameters were differentiating factors between the normal and glaucoma groups (p < 0.05). The area under the receiver operating characteristic curve (AUROC) value of the slope parameters ranged from 0.718 to 0.753. The sum of thresholded cup slope / thresholded cup area parameter was well correlated with visual field mean deviation (r = -0.250, p = 0.028). CONCLUSIONS: The optic disc cup slope parameter obtained with OCT may be a useful parameter for representing glaucomatous cupping.

Since 2008, a nationwide infant and toddler vision screening program has been initiated as a part of the Infant Health Screening Project of the Korean National Health Insurance Corporation. Because children's visual system is in the process of development and they can hardly be treated after its maturation, their vision problems must be screened for and treated in their early age. The program screens for frequent and important eye problems from the age of 4 months to 6 years. The vision screening part consists of history questionnaire section and examination section. The history questionnaire section was devised to screen the symptoms of the target diseases that frequently occur in their due age. The examination section comprises penlight examination up to the age of 2 and visual acuity testing afterward. Amblyopia is by far the most important target disease in all screening sessions. Unilateral or bilateral vision problems, strabismus, other intraocular blinding conditions, blepharoptosis, abnormal head posture of ocular origin, and refractive errors are other important target diseases. Proper knowledge of target diseases and methods is essential for the successful screening. This article is intended to supplement the vision screening of the Doctor's Manual for Infant Health Screening.

BACKGROUND: Intra-aortic balloon pump (IABP)is well known for its hemodynamic benefit but still has its own complications.Proper use of IABP is the best way t o obt ai n maximum benefit with low complication rate. MATERIALS AND METHOD: Twenty one(men 10,female 11) patients were included in this study among the 100 consecutive adult cardiac surgery patients in our hospital.Eighteen(85.7%)were ischemic heart disease patients.They all received IABP therapy due to postcardiotomy cardiogenic shock according to the well-known indications.Their preoperative conditions,intraoperative factors including hemodynamics, postoperative conditions and IABP-related complications were analyzed. RESULT: Nineteen patients(90.5%)were successfully weaned from IABP.There were 2 patients of operative death and the mortality rate was 9.5%.Duration of IABP use was 40.7+/-24.3 hours.There were 2 cases(9.5%)of IABP-related vascular complications that required surgical intervention. CONCLUSION: We concluded that IABP could be used effectively and safely for postcardiotomy cardiogenic shock patients with low complication rate.

Hypertrophic osteoarthropathy, known as Marie-Bamberger's Disease, is characterized by bone and joint changes and clubbing of the fingers and toes. It is well known to occur after longstanding disease of the thorax and intestines. The authors have tried to find patients with hypertrophic osteo-arthropathy in cases with pure silicosis and silscosis complicated by pulmonary tuberculosis. but failed. Recently, the authors discovered 3 cases of hypertrophic osteoarthropathy among some patients with pulmonary tuberculosis. All had had a long history of pulmonary tuberculosis, at least over 1 year duration.

Wiscott-Aldrich syndrome (WAS) is an X-linked recessive disorder affecting males and is characterized by recurrent systemic bacterial and viral infections, purpura due to thrombocytopenia, and an atopic dermatitis-like skin eruption. WAS usually manifests itself early during the first few weeks or months of life with bleeding. A case of WAS with the classical symptoms(eczema, thrombocytopenia and susceptibility to infections) is described in a 12-year-old Korean boy. He had a relatively good outcome.
