Optical coherance tomography will be used to examin the optic nerve and...

Analysis of Retinal Nerve Fiber Layer and Macular Thickness After Congenital Cataract Surgery

Congenital cataract is the main cause of form deprivation amblyopia in children. Current studies confirm that form deprivation amblyopia affects the retinal nerve fiber layer. However, there are different opinions about the effect of amblyopia on the optic nerve fiber thickness around the optic disc at home and abroad. Investigators have performed "cataract extraction with IOL implantation" on children with bilateral and unilateral congenital cataract. Investigators used OCT bi...

Corrected Measurement of the Retinal Nerve Fiber Layer Thickness by Optic Disc Configuration With the Cirrus HD OCT

Because the measurement of the retinal nerve fiber layer thickness is very sensitive to the position of measurement, it may be incorrect in patients with the tilted disc. In the present study, the corrected RNFL thickness by the optic nerve head configuration using the Cirrus HD OCT will be evaluated. If the corrected RNFL thickness is more sensitive to detect the localized RNFL defect, the present software should be upgrade to reflect the optic nerve head configuration.

Comparison of Optic Nerve Head and Retinal Nerve Fiber Layer Parameters Derived From Two Different Methods of Scan Alignment

This prospective, monocentric, non-invasive clinical study is designed to measure normal structural parameters of the optic nerve head, the peripapillary retinal nerve fiber layer, and the macula using the Heidelberg Spectralis OCT device. This study is conducted in normal, healthy volunteers and glaucoma patients. The main goal of the study is to provide an analysis of the comparability of these parameters between two different software versions and their respective method of ...

Video-Laryngoscope Alone or With Bronchoscope for Predicted Difficult Intubation

Using a combination of the video-laryngoscope with the disposable fiber-optic bronchoscope (aScope III) is a feasible way to facilitate successful intubation in a timely manner, in patients with predicted difficult airway due to tumors in the oral cavity, pharynx or larynx To test the hypothesis that combination of video-laryngoscope with the fiber-optic bronchoscope is superior to video-laryngoscope alone for intubation of patients with oral cavity, pharyngeal or laryngeal pat...

A Randomized, Double-blind, Placebo-controlled, Multicenter Study of the Effects of Glatiramer Acetate (GA) on the Retinal Nerve Fiber Layer (RNFL) and Visual Function in Patients With a First Episode of Acute Optic Neuritis (AON). (Octagon)

The main objective of the study is to determine whether GA 20mg SC once daily reduces the amount of axonal loss in the optic nerve (measured by RFNL thickness) after a first event of AON compared to placebo patients and to generate data supporting the potential neuroprotective effect of GA in a human in vivo model of axonal loss..

Optical Coherence Tomography Measurements in Eyes With Band Atrophy

The study is designed to evaluate the ability of optical coherence tomography and VCC scanning laser polarimetry to measure and identify the pattern of band atrophy of the optic nerve in patients with long standing chiasmal lesions. The hypothesis is that these new technologies are able to identify such pattern. The idea is that by using eyes with band atrophy one is able to investigate the ability of the new technologies in measuring the retinal nerve fiber layer particularly ...

High-Resolution Optical Coherence Tomography for Detection of Retinal Nerve Fiber Layer Loss in Band Atrophy of the Optic Nerve

The purpose of this study is to compare the abilities of high-speed,high-resolution (HR) optical coherence tomography (OCT) and Stratus OCT for detection of retinal nerve fiber layer (RNFL) loss in eyes with band atrophy (BA) of the optic nerve.

Effect of Acupuncture on Patients With Chronic Obstructive Pulmonary Disease

This study aims to compare the efficacy of three therapies for chronic obstructive pulmonary disease (COPD) patients: one, conventional drug based on Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 and Chinese Medical Association Guidelines; another, acupuncture, an important part of traditional Chinese Medicine; and finally, the combination of conventional drug and acupuncture, and then determine which therapy is the most suitable for patients with COPD.

Neurotomy of Optic Nerve in Non-Arthritic Anterior Ischemic Optic Neuropathy

Non-arthritic anterior ischemic optic neuropathy is the most common cause of sudden visual loss due to optic nerve involvement in patients above 50 years old. As this problem can be considered as a sclera out let syndrome an there is no effective and successful treatment for it, we decided to do a neurotomy procedure and relax the involved optic nerve in order to achieve acceptable treating outcome.

The Lamina Cribrosa (LC) Changes in the Eyes After Laser-Assisted in Situ Keratomileusis (LASIK)

The burden of LASIK surgery on optic nerve head (ONH) has been controversial. Until now, the change of retinal nerve fiber layer (RNFL) thickness was used as the indicator of the study. In the present study, the investigators intended to investigate whether the changes of the deep and superficial structures around ONH exist or not using EDI OCT.

The Correlation Between AQP-4 Ab and the Visual Function of Patients With Demyelinating ON at Onset

To evaluate the optical coherence tomography (OCT), visual field (VF), Visual evoked po-tential(VEP) characteristics between neuromyelitis optica- related optic neuritis (NMOSD-ON) and multiple sclerosis- related ON (MS-ON) in a Chinese cohort.

Linking Optic Nerve MRI and the Retinal Axonal Loss After Optic Neuritis

This study evaluates the length of optic nerve lesion on 3D-DIR sequence as an imaging biomarker predictive of retinal axonal loss and visual disability, 12 months after the occurence of a first clinical episode of optic neuritis.

Biomechanics of Optic Neuropathy

The participant is being asked to be a subject in this research study because the participant may have a disorder that can cause optic nerve damage and impairment of his/her visual function which is called optic neuropathies (ON). Optic neuropathy refers to damage to the optic nerve (a "cable" connecting the eyes and the brain to transmit the visual signals) due to any cause.In this study, the investigator is using magnetic resonance imaging (MRI) and ophthalmic measures such a...

Assessment of Cholangio-pancreatoscopy for the Diagnosis and the Treatment of Biliary and Pancreatic Diseases

The biliary and pancreatic tumors are rare but the prognosis is pejorative. It was difficult to have histology of these tumors as the samples taken during ERCP were performed under " blind " radiology control. So the diagnostic accuracy was insufficient. The arrival of A new optic fiber endoscope used by only one operator had improved the diagnostic of bilio-pancreatic diseases. However this technology with optic fiber quickly had proved outdated for several reasons: poor mano...

Effects of Fiber on Satiety

The effects of a dietary fiber on hunger and food intake will be tested in men and women. Participants will receive fiber as part of a breakfast meal on two occasions. On another occasion, participants will receive the same breakfast, without added fiber. Their feelings of hunger and fullness will be measured over the day. They will be offered lunch, dinner and an evening snack and how much they eat will be recorded. It is expected that the fiber supplement will enhance their f...

Protective Effect of Phenytoin on Glaucoma

since glaucoma is considered an optic neuropathy, new treatments for glaucoma are being continuously investigated, including neuroprotection. Previous studies implied that phenytoin, a potent anti-convulsive drug, has a neuroprotective role, and Na+ channels blockage was suggested as a possible mechanism. This study predicts that glaucoma patients taking Phenytoin will have a less advanced glaucoma as compared to patients not taking the drug. Glaucoma severity will be determi...
