PURPOSE: To compare the clinical outcomes of glistening-free intraocular lens (IOL) and conventional 1-piece aspheric IOL in implanted in-the-bag. METHODS: After phacoemulsification performed by a single surgeon, 2 different IOLs were implanted: enVista MX60 (glistening-free 1-piece aspheric IOL) in 38 eyes (group A) and AcrySof IQ (conventional 1-piece aspheric IOL) in 46 eyes (group B). Glare symptom score (0-5) obtained by questionnaires, best corrected visual acuity (BCVA), Functional Acuity Contrast Test (FACT), posterior capsular opacity (PCO), glistening formation and spherical equivalent error were compared and analyzed preoperatively and 6 months and 12 months postoperatively. RESULTS: A statistically significant improvement of BCVA and contrast sensitivity postoperatively was observed in all groups. There was statistically significant increase of glistening in group B compared with group A. However, there was no significant difference of FACT scores of spatial frequency in A, B, C, D and E columns and glare symptom score (0-10) obtained by questionnaires 12 months after surgery. Spherical equivalent errors were -0.38 +/- 0.27 D and -0.36 +/- 0.28 D for groups A and B, respectively. PCO occurred in 2 eyes in group A and 4 eyes in group B. CONCLUSIONS: EnVista MX60 IOL showed less glistening formation than AcrySof IQ IOL, however, there was no significant difference in terms of vision quality such as BCVA, FACT and glare symptom score at 12 months postoperatively.

PURPOSE: To investigate the risk factors related to the location of visual field defects in normal tension glaucoma. METHODS: Eighty-one eyes diagnosed as normal tension glaucoma in patients with early glaucomatous visual field defects were divided into central visual field defects and peripheral visual field defects. The difference between the 2 groups based on the intra-individual comparison were assessed with several ocular risk factors such as sex, age, hypertension, diabetes mellitus, smoking, laterality, intraocular pressure, central corneal thickness, cup-disc ratio, peripapillary atrophy, mean deviation, pattern standard deviation, best corrected visual acuity, and refractive errors. RESULTS: The incidence of hypertension in the central visual field defects group (60.6%) was higher than in the peripheral visual field defects group (22.9%, p = 0.001). The central corneal thickness in the central group (533.1 +/- 18.2 microm) was thinner than in the peripheral group (545.0 +/- 30.0 microm, p = 0.003). Hypertension was the only risk factors for central visual field defects (p = 0.001). In both the central group and peripheral group, upper visual field defects were more common than lower defects. CONCLUSIONS: Hypertension in patients with normal tension glaucoma was a factor involved in central visual field defects. Additionally, numerous visual field defects were mainly found the superior portion.

Neurilemmoma is characteristically an encapsulated benign tumor originating from the neural sheath of peripheral, autonomic, and cranial nerves. Whereas between 25% and 45% of all such lesions occur in the region of the head and neck, only 4% of them are found in the nose and paranasal sinuses. Recently, we experienced a case of isolated neuilemmoma of the nasal septum in a 33-year-old female patient who complained of nasal obstruction and postnasal drip over 1 year. The tumor mass was successfully removed by transnasal endoscopic excision under general anesthesia. The patient had an uneventful course with no signs of recurrence. We present our review of the clinicopathologic features, radiologic findings and the value of endoscopy in treatment of this tumor.

A 16-month-old male with mouth breathing due to intranasal mass and obstruction from birth is the subject of this report. CT (computerizd tomography) scan and MCTC (metrizamide CT cisternography) showed only a mass forming a cyst in the left nasal cavity, but magnetic resonance imaging (MRI) demonstrated the connection between the cranial content and the intranasal mass. The mass was concluded to be a congenital intranasal meningocele of a transethmoidal type, and dural plasty by bifrontal craniotomy was initially performed. The remaining herniated sac was removed by intranasal endoscopic resection. MRI has numerous advantages over CT. With MRI's multiplanar capability, there is no need for artificial dilution of the image of surrounding bone, and thus makes it the most valuable image technique for skull base lesions, making the diagnosis of intranasal meningocele much easier than it would be using conventional methods.

BACKGROUND: Outpatient surgery has recently grown at a substantial rate. The development and use of short acting anesthetic and analgesic agents have played a major role in the growth of outpatient surgery. This study was designed to evaluate the intraoperative hemodynamic responses and recovery characteristics, using propofol or isoflurane to maintain the anesthesia. METHODS: A total number of 30, ASA physical status I-II patients scheduled for outpatient surgery, all of whom were to undergo excision of breast mass. The patients were randomly allocated to receive either total intravenous anesthesia with propofol, or inhalation anesthesia with isoflurane after induction of anesthesia with propofol. All patients were ventilated via a laryngeal mask airway (LMA) using a mixture of oxygen and air so that the FiO2 would be 0.4. RESULTS: There were no significant differences in hemodynamic changes during anesthesia in recovery time, or in complications between the two groups. CONCLUSIONS: We conclude that both methods provide reasonably rapid and reliable recovery from anesthesia and are equally acceptable to the patients.

PURPOSE: To evaluate the clinical results of Akreos(R) hydrophilic acrylic intraocular lens (IOL) implantation compared with implantation of Acrysof(R) hydrophobic acrylic IOL. METHODS: We retrospectively analyzed each fifty eyes in 50 patients who had undergone phacoemulsification and implantation of Akreos(R) and Acrysof(R) IOLs, with a minimum follow-up period of one year. RESULTS: Final visual acuity better than 0.5 and 0.8 was 70% and 27% in the Akreos(R) implanted group, and 82% and 46% in the Acrysof(R) group. Predictability less than 1.0D was seen in 23 eyes (46%) in the Akreos(R) group. This is a significantly low percentage compared with that seen in 43 eyes (86%) in the Acrysof(R) group. The final spherical equivalent of -0.93+/-0.92D in the Akreos(R) group represented statistically significant myopic refractive error compared with -0.49+/-0.82D in the Acrysof(R) group. CONCLUSIONS: It is necessary to consider the myopic refractive error toDetermine the proper target refraction for the implantation of Akreos(R) IOL.

PURPOSE: To evaluate the clinical effect of AlloDerm(R) graft on the management of exposed hydroxyapatite orbital implants. METHODS: Seven eyes of 7 patients with large exposure of hydroxyapatite orbital implants were included. After the spicules of hydroxyapatite implants were smoothened with a drill, AlloDerm(R) was applied to the exposed site and sutured with 8-0 Vicryl. One or two layers of amniotic membrane were transplanted on the AlloDerm(R) graft. RESULTS: All patients underwent the drilling, and the mean intervals from drilling to exposure was 73.4 +/- 46.6 months. The mean follow-up period was 11.17 +/- 2.0 months (range, 9-14 months). Complete conjunctival epithelization occurred in 3 eyes, and partial conjunctival epithelization in 3, including one eye which underwent reoperation with AlloDerm(R). In one eye which had been associated with previous infection, hydroxyapatite was removed due to progressive exposure and inflammation of the implant. CONCLUSIONS: AlloDerm(R) graft is useful in the management of exposed hydroxyapatite implant.

PURPOSE: Urolithiasis develops more frequently in patients with a family history (FHx). However, little is known about risk factors in stone formers with a FHx. The aim of this study was to examine the clinico-metabolic characteristics of urinary stone formers according to FHx. MATERIALS AND METHODS: A database of 1,068 stone formers who underwent a complete metabolic evaluation was reviewed. The patients were divided into two groups on the basis of the presence of a FHx. Clinical factors and metabolic parameters were compared between the two groups. RESULTS: There were no significant differences in clinical characteristics, such as gender, age, body mass index, stone episodes, or multiple stones, between the two groups (p>0.05, respectively). Compared with stone formers without a FHx, however, serum calcium concentrations were more elevated in stone formers with a FHx. Also, the urinary excretion of calcium was higher in stone formers with a FHx than in those without a FHx. Other urinary metabolites showed no significant differences between the two groups (p>0.05, respectively). CONCLUSIONS: Our study revealed that stone formers with a FHx had increased urinary calcium excretion as well as elevated concentrations of serum calcium. This finding suggests that urolithiasis in stone formers with a FHx may be associated with calcium metabolic abnormalities.

PURPOSE: To evaluate the long-term visual outcome after surgery for congenital unilateral cataract in children. METHODS: We retrospectively analyzed age, associated ocular disease, preoperative and postoperative visual acuity, type of cataract, operation method, and final visual outcome in 34 children, 12 years or younger, that had undergone congenital unilateral cataract surgery with a minimum follow-up period of one year. RESULTS: The mean age was 4.9 years and the mean follow-up duration was 26.5 months. Final visual acuity was less than 0.1 in 41.2%, better than 0.2 in 58.8%, better than 0.5 in 32.4%, and better than 0.8 in 20.6%. In the group whose preoperative visual acuity was less than 0.1, 27.2% of the eyes had a final visual acuity better than 0.5. This outcome is statistically significant compared with the 71.4% in the group whose preoperative visual acuity was better than 0.2 (p=0.02). In comparing the portion of patients whose final visual acuity was better than 0.5, only 8.3% were in the age group younger than 2 years at surgery; this is significantly lower than the 40.0% of patients in the age group between 3 to 6 years and the 50.0% of patients older than 7 years (p=0.03) whose final visual acuity was better than 0.5. CONCLUSIONS: Because long-term outcome of surgery for congenital unilateral cataract is not always satisfactory, it is necessary to determine the proper surgical time according to preoperative visual disturbance or severity of cataract, and to also do optical correction and aggressive treatment for amblyopia postoperatively.
