PURPOSE The purpose of this study was to evaluate changes in choroidal thickness (CT) in advanced or late-stage primary angle closure glaucoma (PACG) patients who had undergone trabeculectomy. METHODS This study included 23 eyes with PACG that required trabeculectomy. Enhanced depth imaging optical coherence tomography was used to measure CT before and 7 days after trabeculectomy. The relatio...

Purpose To investigate the relationship between axial length (AL) elongation and progression of primary open-angle glaucoma (POAG). Methods AL was measured twice over a 5.1 ± 0.76 (mean ± standard deviation: SD) year period in 125 eyes of 72 patients with POAG. The eyes were divided into not long (AL < 26 mm, 80 eyes) and long (>26 mm, 45 eyes) groups. During this period, patients' visual fie...

Extra-axial medulloblastoma is a rare phenomenon. We report a case in a 5-year-old boy who presented with nausea, vomiting, and gait disturbance. He was treated with total removal of the tumor. This is the first case of an extra-axially located medulloblastoma occurring in the cerebellar hemisphere posteriolateral to the cerebellopontine angle in Korea. Although the extra-axial occurrence of me...

PURPOSE To compare postoperative outcomes and assess factors associated with intraocular pressure (IOP) reduction after phacotrabeculectomy in patients with primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). METHODS This is a retrospective study of patients who underwent phacotrabeculectomy between 2010 and 2013. Factors including age, gender, visual field (VF), the...

in this study, first energy absorption of axial and bending loading is considered. next, thin walled structures under oblique loading are investigated using abaqus computer simulation, where 180 different cases are simulated. simulation results of the thin walled structures under oblique loading were compared with the experimental results of nagel, and good agreement was perceived. simulation r...

Introduction: Anthropometric studies provide valuable information in different populations. This study was conducted to evaluate the anatomical variations of the normal hip joint among Tehran population, Iran, in comparison with other populations. Methods: This study was carried out on hip joint of 260 patients in all ages and both genders referred to the Department of Radiology at Ebn-e Sina ...

We present stability analyses for the boundary-layer flow over broad cones (half-angle ψ > 40◦) rotating in imposed axial flows. Preliminary convective instability analyses are presented that are based on the Orr–Sommerfeld equation for a variety of axial-flow speeds. The results are discussed in terms of the limited existing experimental data and previous stability analyses on related bodies. ...

Characterized by microwave spectroscopy after their formation in a supersonic jet, the axial and equatorial hydrogen bond conformers of the title complex were studied. The axial form--shown in the picture--has been found to be the most stable one. The experimental data are consistent with a C(s) symmetry for both conformers, in which linear hydrogen bonds lying in the symmetry plane bisect the ...

In complex proximal humerus fractures, positioning of the tuberosities can be a challenge. This study demonstrates the constant angle between the pectoralis major (PM) and the medial lip of the bicipital groove (BG) on the horizontal axial plane. This angle can be used to determine the rotation, as well as the positioning of the tuberosities, when planning a hemiarthroplasty or a reconstruction...

OBJECTIVES Accurate localization of the inferior alveolar canal (IAC) is extremely important in some dental treatments. Anatomical variation of the canal means that it can be difficult to locate. The purpose of this study was to assess the relationship of the gonial angle (GA) size and IAC position using cone beam computed tomography (CBCT). MATERIALS AND METHODS In this in vitro study, 61 dr...
