PURPOSE: To assess the reproducibility of circumpapillary retinal nerve fiber layer (cpRNFL) thickness measurement (measurement agreement) and its color-coded classification (classification agreement) by Cirrus spectral domain optical coherence tomography (OCT) in pseudophakic eyes. METHODS: Two-hundred five participants having glaucoma or glaucoma suspected eyes underwent two repeated Cirrus OCT scans to measure cpRNFL thickness (optic disc cube 200 x 200). After classifying participants into three different groups according to their lens status (clear media, cataract, and pseudophakic), values of intra-class coefficient (ICC), coefficient of variance, and test-retest variability were compared between groups for average retinal nerve fiber layer (RNFL) thicknesses and that corresponding to four quadrant maps. Linear weighted kappa coefficients were calculated as indicators of agreement of color code classification in each group. RESULTS: ICC values were all excellent (generally defined as 0.75 to 1.00) for the average and quadrant RNFL thicknesses in all three groups. ICC values of the clear media group tended to be higher than those in the cataract and pseudophakic groups for all quadrants and average thickness. Especially in the superior and nasal quadrants, the ICC value of the cataract group was significantly lower than that of the clear media and pseudophakic groups. For average RNFL thickness, classification agreement (kappa) in three groups did not show a statistically significant difference. For quadrant maps, classification agreement (kappa) in the clear media group was higher than those in the other two groups. CONCLUSIONS: Agreement of cpRNFL measurement and its color code classification between two repeated Cirrus OCT scans in pseudophakic eyes was as good as that in eyes with clear crystalline lens. More studies are required to ascertain the effect of lens status on the reproducibility of Cirrus OCT according to different stages of glaucoma patients.

Malignant Mixed Mullerian tumors(MMMTs) are unusual neoplasms occumng mostly in the uterus and, ralely, they arise in the ovary. The clinical features of malignant mixed mullerian tumor of the ovary are similiar to other ovarian malignancies. The clinical course is rapidly progressive and fatal. The optimal treatment modalities has remained elusive. The most reliable prognostic criterion is the initial tumor stage and the overall survival was poor. We experienced two cases of malignant mixed miillerian tumor of the ovary, so we report these cases with a brief review of the concerned literatures.

PURPOSE: We present a case of uneventful cataract surgery in an idiopathic true exfoliation patient with areas of capsular delamination based on scanning electron microscope and transmission electron microscope results. CASE SUMMARY: A 77-year-old male presented with gradual deterioration of vision over 1 year in duration. Slit lamp examination revealed bilateral nuclear sclerotic cataracts with ring-shaped fibrous membrane floating within the anterior chamber in the right eye. In addition, the patient was diagnosed with cataract and true exfoliation of the right eye. He underwent uneventful phacoemulsification and posterior chamber intraocular lens implantation by placing capsulorrhexis outside the delaminated capsule margin. At 6 months after cataract surgery, the patient showed favorable visual outcome with uncorrected vision of 20/20 and intraocular pressure of 18 mm Hg in the right eye.

PURPOSE: To report a case of non-arteritic anterior ischemic optic neuropathy (NAION) in a patient on hemodialysis. CASE SUMMARY: A 59-year-old female undergoing intravenous hemodialysis developed sudden blurred vision for 2 days. Chronic hypotension and anemia may have been persisted for approximately 6 months before the onset of symptoms. Her corrected visual acuity in both eyes was 0.7 and visual field test showed superior arcuate defect in the left eye. Fundus photography showed inferonasal optic disc swelling and fluorescein angiography revealed hyperfluorescence of the disc in the late phase which was probably attributable to NAION. After 3 weeks, corrected visual acuity was 0.7 in the left eye and fundoscopic finding of the left eye was improved. CONCLUSIONS: Hemodialysis can cause a hypotensive event and anemia which may be associated with NAION. Avoiding acute hypotension and anemia should be advised to prevent development of NAION in dialysis patients.

PURPOSE: To investigate accommodation and progress of patients who showed myopia on manifest refraction in the early postoperative period after LASEK. METHODS: Forty-one eyes were included in the present study which had undergone LASEK surgery from February to March 2012. Seven eyes showed myopia over -0.25 D on manifest refraction at 1 month postoperatively, but showed decreased amount of myopia at 2 months postoperatively and were classified as group 1. The other 34 eyes were classified as group 2. The differences between cycloplegic and manifest refraction (CRSE-MRSE) were defined as the amount of latent accommodation and compared between the 2 groups. RESULTS: Amount of latent accommodation was 0.179 +/- 0.426 D in group 1 (7 eyes), 0.265 +/- 0.303 D in group 2 (34 eyes) preoperatively, 1.286 +/- 0.664 D in group 1, 0.368 +/- 0.536 D in group 2 at 1 month postoperatively, and 0.500 +/- 0.520 D in group 1, and 0.489 +/- 0.546 D in group 2 at 2 months postoperatively. The amount of latent accommodation in group 1 was significantly greater than that of group 2 one month postoperatively. As the amount of latent accommodation decreased, the amount of myopic shift decreased gradually over 2 months in group 1 after surgery. CONCLUSIONS: Transient myopic shift due to increased latent accommodation was observed in several patients one month postoperatively and the amount of myopic shift decreased with time without treatment. Thus, surgeons should consider cycloplegic refraction when planning treatment for patients with myopic regression.

BACKGROUND: With metabolic syndrome (MS) being a major risk factor for cardiovascular disease, and central obesity being a major predisposing factor for MS, intensive research is currently being performed on cutoff values according to race and sex. Menopause is an especially significant factor in designating cutoff values for female central obesity, as menopause brings sudden bodily changes that induce central obesity and increased prevalence of MS. Therefore this study aimed to investigate the cutoff values for the obesity index and its validity in predicting the criteria for MS in Korean women according to menstrual status. METHODS: The study focused on 3,103 women 20 years of age or older participating in the 2007 Korea National Health and Nutrition Examination Survey. Definitions of non-adipose components of MS were defined by the International Diabetes Federation, and menstrual status was judged on the basis of survey results. The sensitivity, specificity, and positive and negative predictive values of the central obesity index (body mass index [BMI], waist circumference [WC], waist-to-height ratio [WHtR]) according to menstrual status for two or more non-adipose components of MS were calculated based on the Youden index. RESULTS: Area under the curve (AUC) values predicting the presence of two or more metabolic risk factors were higher in pre-menopausal women, with AUC values for BMI, WC, and WHtR being, in pre- and post-menopausal women, 23.1 kg/m2 vs. 23.9 kg/m2, 76.1 cm vs. 82.5 cm, and 0.49 vs. 0.53, respectively. The WC cut off (76 cm) for pre-menopausal women was found to be more sensitive and more effective at screening for MS risks than the cutoff value given by the Korea Society for the Study of Obesity. CONCLUSION: The central obesity index showed better predictability for MS risk in pre-menopausal women. Because the central obesity index cutoff values are lower in pre-menopausal women, the possibility of metabolic risk can be considered for pre-menopausal women with WC lower than 85 cm. Assessment and control of other risks are needed accordingly for preventing the development of MS.

Multiple endocrine neoplasia (MEN) Ila is an inherited disease characterized by the development of medullary thyroid carcinoma, pheochromocytoma and hyperparathyroidism. It has been shown to be associated with germ-line mutatians in the RET proto-oncogene. Presymptomatic screening of medullary thyroid carcinoma in MEN IIa families enables the early diagnosis of this tumor with its significant morbidity, We describe a 19-year-old woman fmm a MEN IIa family who was founded by DNA analysis to be a gene carrier of MEN IIa and then was diagnosed, using a pentagastrin stimulation test, as having presymptomatie medullary thyroid carcinoma She underwent thyroidectomy and histologic examination confirmed medullary thyroid carcinoma. It is cancluded that direct genetic analysis for mutations in the RET proto-oncogene should be the diagnstlc test of choice for identifying family members at risk for MEN IIa and thyroidectomy on the basis of genetic analysis is a rational course of action.

The neuroradiologic findings of neurosyphilis are variable. A 36-year-old man was admitted due to gradually progressing abnormal behavior and personality change. The brain MRI revealed bilateral mesiotemporal hyperintensity on FLAIR and T2 weighted MR images. Analysis of serum and CSF demonstrated the presence of antibodies to Treponema pallidum. The patient was treated with penicillin, and he had clinical improvements. Neurosyphilis can manifest with MR imaging abnormalities similar to those of herpes encephalitis.

Scleroderma renal crisis is defined as rapidly progressive renal failure and/or new onset of malignant hypertension during the course of systemic sclerosis. Most patients show clinical features of malignant hypertension, but there have been several reports of normotensive renal crisis. We have experienced a 63 year old female patients with acute renal failure due to scleroderma renal crisis who did not show the clinical features of malignant hypertension. She had taken steroid for the treatment of degenerative osteoarthritis and gradually developed shortness of breath and edema. Her blood pressure on admission was 150/90 mmHg and easily controlled by diuretics. Renal biopsy showed onion-skin appearance in the interlobular arteries with varying degree of tubulointerstitial changes. Her renal function rapidly deteriorated despite ACE inhibitor therapy and cytotoxic therapy had to be initiated because of progressive interstitial pneumonitis and myocarditis. We describe a patient with scleroderma renal crisis who did not show the clinical features of malignant hypertension following steroid treatment.

OBJECTIVE: Few studies on the clinical spectrum of automated pressure-controlled discography (APCD)-defined positive discs have been reported to date. Thus, the present study was undertaken to analyze clinical parameters critical for diagnosis of discogenic pain and to correlate imaging findings with intradiscal pressures and pain responses in patients with APCD-positive discs. METHODS: Twenty-three patients who showed APCD-positive discs were selected for analysis. CT discogram findings and the degrees of nuclear degeneration seen on MRI were analyzed in comparison to changes of intradiscal pressure that provoked pain responses; and clinical pain patterns and dynamic factors were evaluated in relation to pain provocation. RESULTS: Low back pain (LBP), usually centralized, with diffuse leg pain was the most frequently reported pattern of pain in these patients. Overall, LBP was most commonly induced by sitting posture, however, standing was highly correlated with L5/S1 disc lesions (p < 0.01). MRI abnormalities were statistically correlated with grading of CT discogram results (p < 0.05); with most pain response observed in CT discogram Grades 3 and 4. Pain-provoking pressure was not statistically correlated with MRI grading. However, it was higher in Grade 3 than Grade 4. CONCLUSION: APCD-positive discs were demonstrated in patients reporting centralized low back pain with diffuse leg pain, aggravated by sitting and standing. MRI was helpful to assess the degree of nuclear degeneration, yet it could not guarantee exact localization of the painful discs. APCD was considered to be more useful than conventional discography for diagnosis of discogenic pain.
