Human Optical Axial Length and Defocus [PDF]

Investigative Opthalmology & Visual Science, 2010
To investigate the short-term influence of imposed monocular defocus on human optical axial length (the distance from anterior cornea to retinal pigment epithelium) and ocular biometrics.Twenty-eight young adult subjects (14 myopes, 14 emmetropes) had eye biometrics measured before and 30 and 60 minutes after exposure to monocular (right eye) defocus ...

Correlation Between Axial Length and Peripapillary Retinal Nerve Fiber Layer Thickness Determined by Spectral Domain Optical Coherence Tomography: A Cross-sectional Study [PDF]

Journal of Clinical and Diagnostic Research, 2023
Introduction: Peripapillary retinal nerve fiber layer (pRNFL) thickness is an important indicator for the diagnosis and monitoring of glaucoma. Optical Coherence Tomography (OCT) allows for accurate assessment of pRNFL thickness, but previous studies

The effect of transverse ocular magnification adjustment on macular thickness profile in different refractive errors in community-based adults

PLoS ONE, 2022
Purpose Changes in retinal thickness are common in various ocular diseases. Transverse magnification due to differing ocular biometrics, in particular axial length, affects measurement of retinal thickness in different regions.
