ABSTRACT
PURPOSE: To compare the abilities of radionuclide salivagrams (RS) and videofluoroscopic swallow studies (VFSS) to diagnose aspiration in children with aspiration pneumonia. METHODS: The records of children who were referred to the Asan Medical Center between April, 2006 and April, 2012 and who underwent both VFSS and RS to evaluate their recurrent aspiration pneumonia were reviewed (n=67). The aspiration positivity rates of the two tests were determined. The agreement between the tests was assessed by using the kappa statistic. RESULTS: VFSS was more frequently positive (n=26, 39%) than RS (n=23, 34%) (p=0.68). In the 11 children who repeat two test, Repeated examination increased positive rate in each tests (n=11), repeated RS (54%, p=1) is more frequent positive than repeated VFSS (46%, p=0.37). If a cumulative positive test had been defined as at least one positive result, the positive rate of two test was 56% (p<0.05). There was a fair agreement between RS and VFSS (kappa=0.26). CONCLUSION: The RS and VFSS positivity rates in children with aspiration pneumonia were similar but there was fair agreement between the two tests. This result suggests that these investigations to demonstrate aspiration are not interchangeable but complementary.

PURPOSE: To evaluate near and far visual acuity, subjective visual symptoms, and patient satisfaction with a monocular implant of aspheric multifocal IOL (AMO Tecnis ZM900(R)). METHODS: Thirty eyes of 30 patients received phacoemulsifications and monocular implantation of Tecnis ZM900 IOL. The main outcome measures at postoperative 1 week, 1 month, 3 months, and 1 year were uncorrected and corrected near and distant visual acuity, refractory errors, contrast sensitivity, subjective visual symptoms (glare and halo), spectacle independency, and satisfaction. RESULTS: At a 3 month postoperative visit, the mean uncorrected near and distant visual acuities were 0.29+/-0.17 (logMAR) and 0.16+/-0.12 (logMAR),respectively. At 1 year, the mean uncorrected near and distant visual acuities were 0.25+/-0.17 (logMAR) and 0.11+/-0.08 (logMAR). Glare and halo decreased, and contrast sensitivity increased upon 1-year follow-up after monocular implantation of ZM900. Most patients (87%) were satisfied with their visual outcome. CONCLUSIONS: Monocular implantation of multifocal IOL Tecnis ZM900 shows stable surgical outcomes with a high satisfaction rate and enables a high rate of spectacle independency. Postoperative glare and halo, youth, and residual refractive error could be risk factors for dissatisfaction with monocular implantation of multifocal IOL Tecnis ZM900. Proper patient selection can lead to satisfying outcomes.

The aim of current study was to evaluate the incidence and characteristics of ocular sarcoidosis in a Korean population. We conducted a retrospective study of 104 consecutive patients with biopsy-proven sarcoidosis seen at Asan Medical Center in Seoul, Korea, from 1993 to 2007. Medical records, photographs, and fluorescein angiograms were reviewed. Of 104 patients, 22 (21%) had intraocular involvement with female predominance (86%, M:F=3:19). Of the 39 eyes with ocular involvement, 16 (41%) eyes had isolated anterior uveitis, 12 (31%) eyes had intermediate uveitis, 6 eyes (15%) had panuveitis with retinal vasculitis, and 5 (13%) eyes had panuveitis with punched multifocal choroiditis. Mean duration of ophthalmologic follow-up was 62 months. All ocular inflammation was well managed with topical steroid and/or systemic steroid with relatively good final visual outcomes. Ocular complications such as cataract (12 eyes, 30%), glaucoma (6 eyes, 15%), vitreous opacity (1 eye, 3%), cystoid macular edema (3 eyes, 7%), neovascularization (2 eye, 5%), and epiretinal membrane (4 eye, 10%) were related to ocular sarcoidosis. In Korea, where sarcoidosis is very rare, our study indicates relatively low ocular and predominantly non posterior segment involvement with relatively good visual prognosis.

PURPOSE: To demonstrate the capability of anterior segment optical coherence tomography (OCT), to evaluate central corneal thickness (CCT) and to compare the results with those by Orbscan II and standard ultrasound (US) pachymetry. METHODS: One examiner measured the CCT of 44 normal eyes of 22 subjects using anterior OCT, Orbscan II, and US pachymetry. Non-contact measurements by anterior segment OCT and Orbscan II were performed first, followed by contact measurements using US pachymetry. Three consecutive measurements were taken with each method and the mean values and correlations were analyzed. RESULTS: The mean value of the CCT was 531.45+/-32.90 micrometer with anterior OCT, 537.11+/-32.21 micrometer with Orbscan II, and 548.18+/-34.17 micrometer with US pachymetry. There was no statistically significant difference among the values obtained by the 3 instruments (P>0.05). CCT measurements by anterior segment OCT were highly correlated with Orbscan II and US pachymetry (P<0.001) measurements. CONCLUSION: CCT measurements by anterior segment OCT are highly correlated with Orbscan II or US pachymetry measurements. Using non-contact anterior segment OCT, a closer examination of the anterior segment including the cornea is possible. The measurement of the CCT using anterior segment OCT is applicable because result values are similar to measurements by Orbscan II or US pachymetry.

PURPOSE: To evaluate the efficacy of intravitreal triamcinolone acetonide (IVT) for the management of postvitrectomy diabetic vitreous hemorrhage. METHODS: The authors conducted a retrospective study of patients with postvitrectomy diabetic vitreous hemorrhage who were administered 4 mg (0.1 cc) of triamcinolone acetonide ophthalmic suspension. Ocular history, adverse events, BCVA, intraocular pressure, external eye examination, slit-lamp biomicroscopy, fundus examination, B-scan ultrasonography, and fundus photography were assessed on day 1, weeks 1, 2, and 4 and months 2 and 3. RESULTS: There were 19 eyes of 18 consecutive patients with mean follow-up after IVT injection of 28 weeks. Of the 19 eyes, 17 eyes (89%) experienced clearing of vitreous hemorrhage within 1 to 5 weeks (mean, 1.7 weeks) with visible triamcinolone precipitates along with blood clot in the inferior aspect of fundus. Of these 17 eyes, 12 eyes (63%) maintained vitreous hemorrhage-free condition at last follow-up with a mean visual acuity of 20/63 (range, 20/320 20/25), whereas 5 (29%) developed recurrent vitreous hemorrhage after clearing of vitreous hemorrhage. Vitreous hemorrhage was not cleared in 2 eyes, which required surgical procedures. CONCLUSIONS: IVT injection may be beneficial for clearing recurrent postvitrectomy Diabetic Vitreous Hemorrhage.

PURPOSE: The purpose of this study is to report the genetic diagnosis of nine cases of Fabry in one family, either as carriers or patients. METHODS: We conducted analysis of the alpha-galactosidase A gene and ophthalmologic examination of family members of a patient diagnosed with Fabry disease. RESULTS: Our patient, his brother, and two male cousins had Fabry disease; his mother, three aunts, and his female cousin were Fabry carriers. Genetic study revealed deletion mutation (1235-1236delCT) at the alpha-galactosidase A gene in all subjects. Ophthalmologic examination detected whirl-like corneal opacity in all subjects, which is a typical characteristic of Fabry disease.

PURPOSE: To evaluate the internal ostium and lacrimal sac change after external dacryocystorhinostomy (DCR) using digital subtraction dacryocystography (DCG). METHODS: Between May 2003 and July 2004, digital subtraction DCG was performed to assess the ostium and lacrimal sac 6 months after external DCR in 48 patients (n=50 eyes). RESULTS: The lacrimal sac had reformed in 45 (90%) eyes. Mean ostium size was 2.4 mm (0.5~6.1 mm) and these were located at the inferior part of the reformed sac in 39 eyes (78%). Patients with a fistula-type internal ostium, of which the lacrimal sac had not reformed, often complained of epiphora (p=0.005). CONCLUSIONS: Digital subtraction DCG showed successful anatomic changes in the distal lacrimal pathway and confirmed that the internal ostium contracts into a relatively small ostium after DCR. A fistula-type internal ostium may explain the pathophysiology of functional failure after successful DCR.
