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 ...

Ocular axial length and straylight [PDF]

Ophthalmic and Physiological Optics, 2020
Abstract Purpose Straylight refers to an optical phenomenon that takes places in the eye and leads to a deterioration of the retinal image. Past clinical findings suggest an increase of straylight with the eye's axial length, but the aetiology of the phenomenon was unclear.

Global Axial Length Centile Charts.

JAMA Ophthalmol
Importance Myopia is increasingly common worldwide and poses major public health challenges because axial elongation drives sight-threatening complications. Because axial length (AL) is the primary target for myopia management, population-specific AL reference charts are needed.

Axial length targets for myopia control [PDF]

Ophthalmic and Physiological Optics, 2021
Abstract Purpose Both emmetropic and myopic eyes elongate throughout childhood. The goals of this study were to compare axial elongation among untreated progressing myopes, progressing myopes treated with a myopia control contact lens and emmetropes, in order to place axial elongation in the ...

Amphiregulin and ocular axial length [PDF]

Acta Ophthalmologica, 2019
AbstractPurposeTo assess the potential role of amphiregulin as messenger molecule in ocular axial elongation.MethodsThe experimental study included guinea pigs (total n = 78) (age: 3–4 weeks) which underwent bilateral lens‐induced myopization and received 15 days later three intraocular injections in weekly intervals of amphiregulin antibody (doses:5 ...

Topical atropine in retarding myopia progression and axial length growth in children with myopia

Bangabandhu Sheikh Mujib Medical University Journal, 2020
This study was conducted to observe the effect of atropine in retarding myopia progression and axial length growth in 36 myopic children (atropine group, 24; control, 12). The initial spherical equivalent of the atropine group and control group was -3.0 ±

Influence of Axial Length on Conjunctivochalasis

Cornea, 2013
To investigate the relation between the severity of conjunctivochalasis and the axial length (AL) of the eyeball.A prospective nonrandomized study was performed on 165 patients aged 51 to 88 years. The age, gender, medical history, ocular history, grade and other parameters of inferior conjunctivochalasis (classified as nasal, middle, and temporal ...
