Axial Length Estimation in Strabismic Patients

Journal of Pediatric Ophthalmology & Strabismus, 1996
ABSTRACT Background: Previous studies have indicated that axial length determination is important in strabismic patients for defining the limit for a safe maximum recession of the medial rectus. Also, the response to strabismus surgery may be, in part, a function of axial length.

The Effect of Axial Length on Photodynamic Therapy

American Journal of Ophthalmology, 2006
To determine the effect of the axial length of the eye on photodynamic therapy (PDT) light fluence.Laboratory investigation.A calibrated Gullstrand-type model eye was used for this study. The axial length of the model eye was set to different values ranging from 20 to 31 mm, and the light fluence rate for treating a spot of 4 mm was recorded and ...

Effect of Orthokeratology on Axial Length Elongation in Anisomyopic Children.

Optometry and Vision Science, 2019
SIGNIFICANCE Anisomyopia is a natural experimental paradigm that compares dose response between fellow eyes. This study is the first to explore whether orthokeratology (ortho-k) has a dose-response effect on axial length growth and reduces the ...

AXIAL LENGTH FOLLOWING SCLERAL BUCKLING

Retina, 1982
AbstractThe change in the axial length of the eye following 360° scleral buckling using 1/2 thickness, 7.5 mm silicone implanted in a bed of scleral dissection was measured in ten patients and ten autopsy eyes.

Choroidal thickness and axial length changes in myopic children treated with orthokeratology.

Contact lens & anterior eye : the journal of the British Contact Lens Association, 2017
PURPOSE To analyze the change in subfoveal choroidal thickness (SFChT) and its relationship with changes in axial length (AL) in myopic children treated with Orthokeratology (Ortho-k).

Axial Globe Length in Congenital Ptosis

Journal of Pediatric Ophthalmology & Strabismus, 2015
Purpose: To compare axial globe length between affected and unaffected sides in patients with unilateral congenital ptosis. Methods: This prospective observational study included 37 patients (age range: 7 months to 58 years). The axial globe length, margin reflex distance-1 (MRD-1),

Axial length and age at cataract surgery

Journal of Cataract and Refractive Surgery, 2004
To examine the relationship between the axial length of the eye and age at surgery for cataract.Postgraduate teaching hospital.A retrospective review of a consecutive series of 1776 patients older than 40 years was performed. The patient's age at first-eye surgery, axial length, and preoperative and postoperative best corrected visual acuities were ...

Improving refractive outcomes at extreme axial lengths with the IOLMaster: the optical axial length and keratometric transformation

British Journal of Ophthalmology, 2009
To optimise the relationship between the actual and predicted refractive outcomes following phacoemulsification and axial length of the eye. Four intraocular lens (IOL) power calculation formulae were compared: SKR-T, Holladay I, Hoffer-Q and Haigis. Optical axial length transformation based on the original calibration of the IOLMaster was tested to ...

Association of Axial Length Growth and Topographic Change in Orthokeratology

Eye & contact lens, 2018
Objectives: To investigate the topographic factors related to axial length (AL) growth rate in orthokeratology. Methods: Clinical data of myopic children with orthokeratology lenses from 2010 to 2016 were investigated. Corneal topography (Orbscan II) and
