Prospective Evaluation of a Smartphone Application, GoCheckKids™, to Detect Amblyopia Risk Factors...

Amblyopia

The objective is evaluation of GoCheck Kids, a smartphone application ('App'), for use as a photo screening device in a pediatric population to detect amblyopia risk factors (ARFs).

Comparison of Deviation Types Among Astigmatic Children With Or Without Amblyopia

Astigmatism of Both EyesAmblyopia1 more

the records of astigmatic children were reviewed and any deviation was investigated at near and distance. refractive errors, stereopsis, convergence insufficiency were also evaluated. children were divided into two groups according to the presence of amblyopia and ocular deviations and other parameters were compared between groups.

OCTA Analysis In Children After Lensectomy

Deprivation Amblyopia

The aim of this study is to quantify and compare the foveal avascular zone (FAZ), the parafoveal and foveal vessel density of superficial (SCP) and deep capillary plexus (DCP) and retinal thickness in deprivation amblyopic eyes, fellow non-amblyopic eyes, and age-matched normal eyes, using optical coherence tomography angiography (OCTA). The FAZ, parafoveal and foveal SCP and DCP, and retinal thickness were measured in normal controls and at least 3 months postoperatively in children with unilateral cataract and compared between groups after adjusting for axial length and spherical equivalents.

MRI-based Biomarkers for Predicting Punctate White Matter Lesions in Neonates

Brain DiseasesAmblyopia3 more

As a common white matter (WM) disease in preterm neonates, punctate white matter lesion (PWML) frequently leads to the abnormalities of brain development (e.g. the motor, visual and auditory disorders), even to cerebral palsy (CP) and amblyopia during childhood. However, it is lack of certain methods in identifying the prognosis of PWML. Through using various advanced MRI techniques, neuro-behavioral and visual assessments, a multicenter longitudinal study would be conducted to follow-up the PWML neonates with varying spatial-position and degree lesions. Through tracking the variations in WM microstructures from neonate period to childhood (2 years old and 3 years old), this study aims to explore (1) the potential relations between varying PWMLs and motor and visual disorders (2) the relations between WM MRI-metrics and neurodevelopmental assessment results, and thus determine the early biomarkers to identify CP and amblyopia.

Changes in Amblyopia Using Optical Coherence Tomography

Amblyopia

There have been multiple trials to investigate the morphological changes in the macula and retinal nerve fiber layer of amblyopic eyes, due to the different published results and the lack of evident association between these changes and the patients' parameters. So, we perform this study to compare the variations in macular parameters (central thickness, average thickness, macular volume) and peripapillary thickness in different cases of amblyopic eyes versus the normal fellow eyes using spectral-domain optical coherence tomography. In addition, to estimate the relationship of optical coherence tomography variations with different defined patients' parameters (age, sex, best corrected visual acuity, spherical equivalent refractive error, and axial length).
