Optical coherence tomography with a Fizeau interferometer configuration [PDF]

, 2005
We report the investigation of a Fizeau interferometer-based OCT system. A secondary processing interferometer is necessary in this configuration, to compensate the optical path difference formed in the Fizeau interferometer between the end of the ...

Optimization of a field-widened Michelson interferometer [PDF]

, 1985
This paper considers the optical design of a wide-angle fixed-path Michelson interferometer consisting of two arm glasses and an air gap. It is shown that this configuration can be optimized to give (a) extra large fringes (over 50° in diameter) over a

Impact of Unilateral Orbital Radiotherapy on the Structure and Function of Bilateral Human Meibomian Gland

Journal of Ophthalmology, Volume 2018, Issue 1, 2018., 2018
Background. Radiotherapy (RT) has widely been used to treat ocular tumors, yet the impact of orbital radiation to the meibomian gland has rarely been studied. Our study aims at evaluating the bilateral meibomian gland structure and function 12 months after unilateral orbital RT in patients with ocular tumors. Methods.

Imaging fibre bundles for Fizeau-based optical coherence tomography [PDF]

, 2008
An OCT system incorporating a coherent fibre imaging bundle is described. Fibres are accessed sequentially by a beam focused onto the input face of the bundle, allowing 2D or 3D images to be acquired using point detection.

Meibomian Gland Dysfunction in Type 2 Diabetic Patients

Journal of Ophthalmology, Volume 2017, Issue 1, 2017., 2017
Purpose. To investigate meibomian gland and tear film function in patients with type 2 diabetes. Methods. This prospective study compared changes in meibomian gland and tear film function in type 2 diabetic patients with nondiabetic patients. Meibomian gland function was evaluated by measuring lipid layer thickness (LLT), grading of meibomian gland ...

Evaluation of Monocular Treatment for Meibomian Gland Dysfunction with an Automated Thermodynamic System in Elderly Chinese Patients: A Contralateral Eye Study

Journal of Ophthalmology, Volume 2016, Issue 1, 2016., 2016
Purpose. To investigate the safety and efficacy of monocular treatment for elderly Chinese patients with meibomian gland dysfunction (MGD) with an automated thermodynamic system. Methods. This study was a prospective, examiner‐masked, contralateral eye clinical trial. The eye perceived by the patient to be worse (test eye) received a 12‐minute LipiFlow
