PURPOSE: To compare the structure and function of the Meibomian gland and eyelid blinking patterns between thyroid eye disease (TED) patients with dry eye and nonthyroidal dry eye (DE) patients. METHODS: Interferometer (lipid layer thickness, incomplete blinking rate and meibography) and (3) slit-lamp biomicroscopy (corneal staining, tear break-up time (TBUT), meibum expression). RESULTS: The TED and DE groups included 98 and 62 patients, respectively. The meiboscores of the upper eyelid in TED

BACKGROUND: Numerous surgical techniques of silicone tube intubation in congenital nasolacrimal duct obstruction (CNLDO) have been described; these techniques can be divided into monocanalicular intubation (MCI) and bicanalicular intubation (BCI). The aim of this study was to compare the clinical effectiveness of MCI versus BCI of CNLDO. METHODS: In a prospective, nonrandomized, comparative case study, patients with CNLDO underwent probing under endoscopic control and either BCI or MCI under gen

PURPOSE: This study aimed to evaluate the clinical efficacy of canalicular laceration repair using monocanalicular intubation with Monoka tubes. METHODS: A total of 36 single lacerated canaliculi were repaired using monocanalicular intubation with Monoka tubes, without mucosal anastomosis of the canaliculi, and were retrospectively reviewed. Demographic information, injury locations, associated ocular injuries, complications and outcomes were analysed. RESULTS: Mean patient age was 34 years (ran

In order to describe the demographics, etiologic and clinical factors, and outcomes of orbital fractures in children, we have reviewed a case series of 17 patients under 18 years of age with internal orbital fractures (i.e., without involvement of the orbital rim) presenting to the Ghil hospital between March 2000 and June 2001. For 15 of the patients, we performed orbital wall reconstruction with Medpor barrier sheet implantation (thickness 1mm) through transconjunctival approach under endoscop

OBJECTIVE: The aim of this study was to determine whether the optic nerve is affected by thyroid eye disease (TED) before the development of dysthyroid optic neuropathy with diffusion-tensor imaging (DTI). METHODS: Twenty TED patients and 20 controls were included. The mean, axial, and radial diffusivities and fractional anisotropy (FA) value were measured at the optic nerves in DTI. Extraocular muscle diameters were measured on computed tomography. The diffusivities and FA of the optic nerves w

연구배경: 우리나라에서 당뇨병의 유병률이 급격히 증가하고 있음은 주지의 사실이다. 당뇨병 인구의 증가는 각종 합병증 특히 심혈관질환으로 인한 사망의 증가, 삶의 질 저하 및 의료비 상승과 직결된다. 그럼에도 불구하고 우리나라에서 당뇨병이 제대로 관리되고 있는지에 대하여는 적절한 조사가 부족한 것이 현실이다. 본 연구는 우리나라에서 당뇨병의 유병상태 및 그 관리 실태를 파악하고자 2005년도에 대한당뇨병학회 당뇨병 기초통계연구 Task Force Team과 건강보험심사평가원 조사연구실이 공동으로 시행한 연구이다.방법: 본 연구는 2003년 1월부터 12월 사이에 건강보험심사평가원에 당뇨병으로 보험청구가 발생한 2,503,754명의 환자 중에서 2단계 집락추출법을 사용하여 무작위 추출된 3,902명에 대한 현장 방문조사와 전화설문으로 이루어졌다. 연구에 사용된 의무기록조사지 및 환자설문지는 대한당뇨병학회 당뇨병 기초통계연구 Task Force Team에서 자체 개발하여 사용하였다.결과:

In our study, increased contrast sensitivity and improved functional visual acuity after upper eyelid blepharoplasty were caused by changes in ocular HOA and the degree of lash ptosis after surgery. There were no changes in corneal topography or astigmatism.

This study presents a normal range of Korean lacrimal gland dimensions as measured by computed tomography. This range can aid in differentiating diseased and nondiseased lacrimal glands, especially when used in combination with physical examination. These data may also be useful in clinical trials that involve lacrimal gland size.

PURPOSE: To assess the relative frequency and clinicopathologic characteristics of benign conjunctival tumors. METHODS: A retrospective study of 80 consecutive patients admitted to our hospital with benign eyelid and conjunctival tumor between April 2000 and November 2002 was undertaken, and clinical records including age, sex and involved site of tumors and pathology slides of the patients were reviewed retrospectively. RESULTS: Twenty-three males and 33 females presented with benign eyelid tum
