Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossa. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present two cases of bilateral renal agenesis, one is diagnosed by ultrasonography after amnioinfusion at 24 weeks gestation, the other is diagnosed postnatally after term delivery.

A ICL TM(STAAR Collamer Posterior chamber Implantable Contact Lens) lents ranging from -11D to -21.3D. And then we investigated the visualwas implanted in 12 eyes of 7 patients with preoperative spherical equivalents ranging from -11 D to -21.3 D. And then we investigated the visual acuity, mean endothelial cell loss, change of refractive error and postoperative complications.Average follow-up was 28.1 months. In the immediate postoperative days, all eyes had a significant increase in uncorrected visual acuity and the best corrected visual acuity was improved in 7 eyes(58.3%). Mean percent difference between preoperative and postoperative endothelial cell count was 3.22+/-0.05% . The mean preoperative spherical equivalent refraction was -15.65+/-2.78 D. At a mean follow-up of 1 month, mean spherical equivalent refraction was -1.67+/-0.72D, at a 6months, 12 months, 24 months, mean spherical equivalent refraction was each -1.56+/-0.72D, -1.63+/-0.68D, -1.73+/-0.76D. During follow-up days one eye developed an faint anterior subcapsular cataract but the patient remained symptom free. Other reported complication was transient increased intraocular pressure. Although the follow-up in our study was limited cases(12 eyes), from our experience, the posterior chamber implantable contact lens was efficacious and safe in the correction of high myopic refraction errors.

PURPOSE: To observe MR findings of vascular abnormality in Sturge-Weber syndrome and to determine the value of MRI in diagnosis. MATERIALS AND METHODS: Ten patients with Sturge-Weber syndrome (age : 3 months-32 years)were evaluated by MR imaging ; in six and four cases, respectively, the results were correlated with those of CT and angiography. We retrospectively analysed changes in the cortical vein and deep venous system, including the medullary and subependymal vein, as well as an largement of the choroid plexus, leptomeningeal enhancement, and changes in diploic space. RESULTS: In all cases except one, in which non-contrast enhanced study had been performed, varying degrees of leptomeningeal enhancement were seen. In nine cases the cortical vein became smaller; enlargement of the choroid plexus was seen in eight cases, change in the diploic space in seven (including three in which there was angiomatous involvement), and enlargement of the deep venous system in seven. In younger patients, collateral pathways were less developed and leptomeningeal angiomatous changes were more pronounced than in those who were older. CONCLUSION: MRI is a useful modality for the evaluationn of vascular changes in Sturge-Weber syndrome. These changes vary according to a patient's age and the duration of the disease.

BACKGROUND: Defects caused by excision of benign lid margin tumors are conventionally repaired by reconstructive surgery. However, second intention healing is another option for managing wounds on the lid margin. OBJECTIVE: To evaluate the effectiveness of second intention healing after a shave excision of benign tumors on the lid margin. METHODS: Lid defects following a shave excision of the lid margin tumor were allowed to heal by second intention in 25 patients (26 lesions). The epithelialzation period was calculated, and cosmetic and functional results and complications were evaluated by photographs and ophthalmological examination. RESULTS: The locations of the defects were as follows: upper lid (n=13), lower lid (n=11), and both upper and lower lids (n=1). The mean tumor size was 3.8x3.6 mm, and the mean epithelialization period by second intention was 6.1+/-1.2 weeks. Pathological examinations revealed intradermal nevus (12 cases), compound nevus (five cases), squamous papilloma (five cases), and epidermal cyst (three cases). No patients had a corneal erosion, trichiasis, or hypertrophic scar, except loss of cilia in two cases. The functional and cosmetic results were satisfactory in all patients. CONCLUSION: Healing by second intention is a safe and effective alternative to surgical reconstruction after a shave excision of benign lid margin tumors.

PURPOSE: To present easily measurable 2D orbit computed tomography (CT) reference data that can be used in a preoperative study for orbital decompression and classification of individual orbital morphologies. METHODS: The study sample was composed of 77 patients with orbital contusion (42 Asian males + 35 Asian females = 154 orbits) who visited the emergency room of the Korea University Guro Hospital from September 2012 to June 2013. Patients with orbital wall fracture, retrobulbar hemorrhage, or eyeball rupture were excluded. Medical records including 2D orbit or facial bone CT were retrospectively reviewed and 4 orbital parameters (orbital length, OL; globe length, GL; GL/OL ratio and 2D cone angle) were measured. RESULTS: The average OL was 42.53 +/- 2.46 mm (35.63-49.09 mm) and average GL was 24.83 +/- 1.09 mm (22.75-28.13 mm). The average GL/OL ratio using these 2 parameters was 0.59 +/- 0.04 (0.50-0.68). The posterior cone angle was on average, 45.96 +/- 5.91degrees (29.35-60.04degrees). CONCLUSIONS: Simple measurement of 4 parameters using 2D orbit CT and classification of Asian individual orbital morphology may help in the choice of the most effective surgical technique for decompression surgery in thyroid eye disease patients.

During the recent epidemic period (1995~1996), seven strains of rubella virus were isolated in Korea. To analyze phylogenetic relationship between seven Korean strains and rubella virus strains from other different geographical areas, structural genes (E1, E2 and C) of Korean strains were enzymatically amplified and automatically sequenced. The sequence similarities of the E1, E2 and C genes of the cosmopolitan types were 95.8~98.1%, 92.6~99.2% and 96.4~99.3% based on 1,441, 122 and 139 nucleotides and 96.9~98.5%, 90~100% and 97.8~100% based on 480, 40 and 46 amino acids compared to the sequences of strain RA27/3, respectively. In contrast, the sequence similarities of the E1, E2 and C genes of the Asian types were 91.5~92.1%, 83.6~88.5% and 91.4% based on nucleotides ad 96.9~97.7%, 85.5% and 97.8% based on amino acids compared to the sequences of strain RA27/3. respectively. However, immunodominent epitopes of the E1 gene of the cosmopolitan and Asian types were well conserved, and the growth patterns in cell culture and immunofluorescent antibody titers in cross-reaction test showed no differences between two different types. In phylogenetic analysis based on nucleotide sequences of each gene regions, the comopolitan and Asian types formed tow distinct phylogenetic lineages. These data showed two distinct genotypes of rubella viruses cocirculated in Korea, but no significant differences in the antigenicity of two different rubella virus strains were found.
