PURPOSE: To evaluate the clinical results of short duration photodynamic therapy (PDT) using verteporfin in patients with chronic central serous chorioretinopathy (CSC). METHODS: We retrospectively examined 15 eyes after PDT for chronic central serous chorioretinopathy. PDT for 83 seconds was evaluated for 8 eyes, and PDT for 60 seconds was evaluated for 7 eyes. Improvement in vision and changes in central macular thickness were evaluated with an optical coherence tomogram (OCT), and improvement in leaking was evaluated with a fluorescein angiogram (FA). Recurrence was also studied. RESULTS: Visual acuity improved from 0.39 to 0.57 (p=0.04), and the mean central macular thickness decreased from 426.29 micrometer to 184.71 micrometer (p<0.01) in 7 eyes treated with PDT for 60 seconds. There was no significant change in visual acuity between the two groups (p=0.77) or in central macular thickness (p=0.52). Central macular exudation resolved completely in all eyes. After PDT, there was no recurrence during the follow-up period. CONCLUSIONS: Short duration PDT with verteporfin appears to be a beneficial treatment option for patients with chronic CSC.

PURPOSE: To examine the clinical effects of intravitreal bevacizumab injections for patients with macular edema secondary to branched retinal vein occlusion (BRVO). METHODS: Nineteen patients (19 eyes) diagnosed with BRVO within the three month study window, having visual acuities under 0.5 and significant macular edema within two-disc diameters of the fovea were included in the present study. The author evaluated the patients' responses to bevacizumab (1.25 mg/0.05 mL) treatment using visual acuity and central macular edema measurements. RESULTS: The mean visual acuity improved from 1.06 (+/-0.10 logMAR unit) at baseline to 0.68 (+/-0.09 logMAR unit), 0.279 (+/-0.049) at one month, 0.67 (+/-0.9 logMAR unit) at two months, 0.61 (+/-0.09 logMAR unit) at three months and 0.54 (+/-0.10 logMAR unit) at six months. The mean central macular thickness decreased from 552.9 micrometer (+/-41.0) at baseline to 290.0 micrometer (+/-36.7) at one month, 290.0 micrometer (+/-36.7) at three months and 281.3 micrometer (+/-30.1) at six months. No adverse side effects were observed following injections. CONCLUSIONS: The observed macular edema and visual acuity improvements, as well as lack of serious adverse side effects after intravitreal bevacizumab injection, demonstrated that intravitreal bevacizumab injection may be useful for treating patients with macular edema secondary to BRVO.

PURPOSE: To evaluate the correlation between lesional variation and visual outcome and natural course of idiopathic choroidal neovascularization (CNV) in the patient who had been treated with conservative treatment only. METHODS: Best corrected visual acuity (BCVA), fluorescein and indocyanine angiographic examination (FAG and ICGA) and comparative analyses were performed for twenty eyes diagnosed with subfoveal and juxtafoveal idiopathic CNV and the long-term (mean, 24.7 months) natural course was followed. RESULTS: Juxtafoveal CNV occurred in 12 eyes (60%) and final BCVA in 17 eyes (85%) improved over 1 line or remained unchanged. Minimal or no leakage of final FAG was shown in 12 eyes (60%). In final ICGA, dark rim was found in 16 eyes (80%), hyperfluorescent area in 12 (60%) and focal choroidal venous dilatation in 3 (15%). Juxtafoveal CNV had more favorable visual outcome than subfoveal CNV and the increased dark rim and decreased hyperfluorescent area in ICGA were significantly correlated with favorable visual outcome. CONCLUSIONS: Idiopathic CNV had a favorable visual outcome during long-term follow-up period with conservative treatment only.

A short nose is one that extends less than one third of the vertical height of the face or whose distance from nasion to tip-defining point is short. Lengthening short noses has been regarded as one of the most challenging and at times vexing tasks in secondary nasal surgery. For correction of short nose, nasal tip supporting tissues from alar cartilages are released and nasal tip is positioned and fixed again. There are five important nasal tip supporting tissues, fibrous connection between upper lateral cartilage and lower lateral cartilage, hinge region(fibrous connection between lateral border of lateral crus and pyriform aperture), interdormal attachment to anterior septal angle (fibrous tissue between anterior septal angle and middle crus), fibrous connection between septum and foot plate of medial crus and dermocartilaginous ligament. This study is to find out which one of the five nasal tip supporting tissues is the most important in short nose correction except dermocartilaginous ligament which has to be released during rhinoplasty. We dissected ten noses from ten fresh cadavers. Five were male and five were female with an average age of sixty three for all ten. We measured the distance between anterior septal angle and tip-defining point in every step of soft tissue dissection releasing the alar cartilage and mucosa, that are often released in short nose corrections and caudally pulling them to the direction of tip-defining point. First, distances were measured in resting and in pulling of alar cartilage. Further, changed distance were measured after releasing nasal tip supporting tissues beginning from the dissection of soft tissues between lateral crus and upper lateral cartilage to that of mucoperichondrium underneath upper lateral cartilage and septal mucoperichondrium. In each process, we found the average and standard variation, confirmed effects of those values to the lengthening of short noses. Dissecting upper lateral cartilage and lateral crus of alar cartilage was most effective in short nose correction. We also found it effective to release the hinge area and dissect the mucoperichondrium under upper lateral cartilage in lengthening the short noses.

PURPOSE: To determine the factors influence retinal nerve fiber layer (RNFL) and optic nerve head (ONH) parameters measured by Stratus optical coherence tomography (OCT). METHODS: Topographic RNFL thickness and optic disc parameters of 129 healthy Korean subjects of aged 14 to 87 were measured using the fast retinal nerve fiber layer thickness and fast optic disk algorithms of Stratus OCT. One eye of each subject was randomly selected for statistical analysis. Using multiple linear regression, the effect of optic disc area, age, refractive error, and zone beta on each parameter was analyzed. RESULTS: Large discs had large horizontal integrated rim width (HIRW), cup area, rim area, C/D area ratio, and vertical C/D ratio. The thickness of average, superior, inferior, and nasal quadrant RNFL increased significantly with an increase in optic disc area. Average and superior quadrant RNFL thickness, and HIRW decreased with age. Refractive error showed a correlation with the vertical integrated rim area, horizontal C/D ratio, and temporal quadrant RNFL thickness. Gender and zone beta had no statistically significant influence on ONH and RNFL parameters. CONCLUSIONS: This study shows that optic disc size affects most RNFL thickness and ONH parameters. Because of the relationships revealed in this study, optic disc area in addition to age should be considered when the Stratus OCT RNFL thickness and ONH parameters are interpreted.

BACKGROUND: In the diagnosis of acute myocardial infarction, measurement of CK-MB is widely used as an enzyme test, but it needs special instruments, lacks specificity in the presence of concomitant skeletal muscle injuries, and has narrow diagnostic time window. Cardiac specific troponin T-a new marker for the diagnosis of myocardial injury-is now available. Besides the quantitative assay, rapid qualitative asay is also possible with the development of rapid assay Kit. We studied about the efficacy of the Troponin T rapid assay Kit in early doagnosis of actue myocardial infarction in the emergency room. METHODS: Total Ck, Ck-MB, LDH and serum troponin T activities were determined when the patients arrived at the emergency room and at the same time Troponin T rapid assay kit test was done. Final diagnosis was made through the serial measurement of CK, CK-MB and LDH. Diagnostic efficacy of each rest was evaluated. RESULTS: Overall diagnostic sensitivity and specificity of Troponin T rapid assay kit were 0.97 and 0.91. When evaluated only with the initial results, Troponin T rapid assay kit showed sensitivity 0.87, specificity 0.97, serum troponin T 0.75, 0.92, and Ck-Mb 0.81,0.95. In one patient who was finally diagnosed as a septic shock, Ck-MB was elevated but serum troponin T was not and Troponin T rapid assay kit test showed negative result. CONCLUSION: Troponin T rapid assay kit test seems to show nearly the same sensitivity and specificity in diagnosis of acute myocardial infarction compared to CK-MB. This test can be done simply and easily in a short time. Thus, with the use of this test, morbidity, mortality and economic loss due to misdiagnosis and delay of diagnosis of myocardial infarction might be reduced.

On view of the absent or minimal osmotic diuresis in end stage renal disease, hyperglycemia on maintenance hemolysis as compared to nonketotic hyperosmolar status without underlying advanced renal failure has been noted to show a wide clinical spectrum form severe manifestations by hypertonicity to no clinical manifestations at all. We experienced a 60-year-old man with a known history of type 2 diabetes mellitus on maintenance hemodialysis for 2 years, who was admitted 4 times within 1 year with hyperglycemia (>500 mg/dL) accompanied by recurrent nausea and vomiting at each admission. However, the calculated effective osmolality (tonicity) in this case ranged only from 286 to 303 mOsm/kg H2O. During the past 6 months following meticulous education for the importance of compliance to medication, especially prokinetics for diabetic gastroparesis, he developed no further episode of hyperglycemia or nausea and vomiting.

PURPOSE: To evaluate the postoperative surgical outcome of vitreous surgery with removal of the internal limiting membrane assisted by indocyanine green (ICG) and the epiretinal membrane assisted by triamcinolone acetonide (TA.) METHODS: We examined the posterior vitreous state with ultrasound and OCT. The procedures performed included pars plana vitrectomy with internal limiting membrane removal assisted by ICG and epiretinal membrane peeling assisted by TA. We prospectively examined 9 eyes with retinal detachment resulting from a macular hole and with follow-up periods longer than 12 months. The main outcome was evaluated by the anatomical success rate, functional success rate, and postoperative complications. RESULTS: In the 7 of 9 eyes, the retina was reattached with closure of the macular hole and without closure of the macular hole in 1 of 9 eyes. Successful retinal reattachment was achieved in 8 eyes (88%) after the initial surgery and in one eye after an additional operation. Visual acuity was improved in 7 eyes, was unchanged in one eye, and decreased in one eye. The functional success rate was 78%. CONCLUSIONS: In retinal detachment resulting from a macular hole, removal of the internal limiting membrane by ICG, and the posterior hyaloid membrane and epiretinal membrane by TA typically results in anatomical and functional success.

Ovarian myoma is a rare mesenchymal tumor, accounting for only 1% of benign ovarian neoplasm. These tumors only originate from smooth muscle on the walls of blood vessels in the cortical stroma, in the corpus luteum and in the ovarian ligaments at the point of attachment to the ovary. Most patients are asymptomatic and the tumors are usually found incidently during operations or at autopsies. Two cases of ovarian myoma experienced in our hospital recently are reported with a brief review of the literatures."
