Association Between Peripheral Retinal Defocus and Myopia by Multispectral Refraction Topography in Chinese Children.

Objective: To investigate the association between the peripheral refractive errors of the fundus in different regions and moderate and high myopia.

Methods: In this case-control study, 320 children and adolescents aged 6 to 18 years were recruited. Peripheral refractive errors were measured using multispectral retinal refractive topography (MRT).

Analysis of biometric parameters of cataract eyes measured with optical biometer Lenstar LS900, IOL Master 700, and OPD-SCAN III.

Background: To compare the characteristics of biometric measurements among the LS900, IOL Master, and OPD-SCAN III in patients with mild-to-moderate cataract.

Methods: We recruited 85 eyes of 78 patients diagnosed with mild-to-moderate cataract at our hospital between January and April 2023. The K (average corneal curvature; K1 and K2), astigmatism (AST), and white to white (WTW) were measured using those three devices, respectively.

Foveal avascular zone in normal human eyes by optical coherence tomography angiography.

Objective: To analyze the influence factors of the area of superficial plexus foveal avascular zone (FAZ) and related indexes of fovea measured with optical coherence tomography angiography (OCT-A) in normal subjects.

Methods: This was a cross-sectional study from November 2020 to May 2021 in the Inner Mongolia Autonomous Region, China. Each subject received related eye examination.

Agreement of anterior segment measurements between LenStar LS 900 optical biometer and OPD Scan III wavefront aberrometer devices in eyes with cataract.

Purpose: To compare the inter-device agreement of anterior eye segment measurements between LenStar LS 900 optical biometer and OPD Scan III wavefront aberrometer.

Methods: This is a retrospective study involving 59 patients (78 eyes) with cataract. Their angle Alpha, angle Kappa, pupil size and white-to-white (WTW) distance were measured by LenStar LS 900 optical biometer and OPD Scan III wavefront aberrometer, respectively, and pairwise agreement comparisons were performed between them.

Correlations among peripapillary vasculature, macular superficial capillaries, and eye structure in healthy and myopic eyes of Chinese young adults (STROBE).

The correlations between retinal vessel distribution, anterior chamber depth (ACD) and other myopic eye structural parameters remains elusive. This study aims to investigate retinal vasculature and eye structure correlations in healthy and myopic eyes of Chinese young adults.In this cross-sectional study, 181 eyes (97 adults) were recruited.
