Biometric indicators of anterior segment parameters before and after laser peripheral iridotomy by swept-source optical coherent tomography

BMC Ophthalmology, 2022
Background Primary angle closure glaucoma (PACG) is the most common type of glaucoma in China. Laser peripheral iridotomy (LPI) is the primary choice to treat PAC: We aim to evaluate the changes of biometric parameters of anterior segment and to find ...

Increased cranio-caudal spinal cord oscillations are the cardinal pathophysiological change in degenerative cervical myelopathy

Frontiers in Neurology, 2023
IntroductionDegenerative cervical myelopathy (DCM) is the most common cause of non-traumatic incomplete spinal cord injury, but its pathophysiology is poorly understood. As spinal cord compression observed in standard MRI often fails to explain a patient'

A Prospective Study of Anterior Segment Ocular Parameters in Anisometropia [PDF]

Korean Journal of Ophthalmology, 2017
The aim of this study was to investigate the differences in anterior segment ocular parameters in anisometropia >1 D.This study included 202 eyes of 101 subjects ranging from 10 to 40 years of age with anisometropia of 1 D or more. The subjects were divided into groups according to anisomyopia, anisoastigmatism, and anisohypermetropia.

Seasonal variations in anterior segment angle parameters in myopes and emmetropes

Clinical and Experimental Optometry, 2023
Seasonal variations are known to occur in a range of ocular parameters and in conditions including refractive error and glaucoma. It is of clinical importance to know if seasonal changes also occur in anterior segment angle parameters, given that they can influence these conditions.The study aimed to examine the seasonal variations in anterior segment ...
