Corneal thickness and axial length

American Journal of Ophthalmology, 2005
A thin central cornea has been reported to be a risk factor for developing primary open-angle glaucoma among ocular hypertensive eyes. A thin scleral bed of lamina cribrosa seen in deeply excavated optic nerves in glaucomatous eyes is a quintessential finding in advanced glaucomatous eyes. Association between thin cornea and weak sclera contributing to

Axial length in applanation tonometry

Journal of Cataract and Refractive Surgery, 2002
To investigate the clinical applicability of a physical principle that suggests that a large globe offers less resistance to applanation than a smaller one.Referral practice, Bridgeport, Connecticut, USA.The correlation between axial length and applanation tonometry in 513 adult eyes, arbitrarily chosen from a referral practice, was examined using ...

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 ...

Variation of multifocal electroretinogram with axial length

Ophthalmic and Physiological Optics, 2003
Abstract Introduction: The first‐order kernel response of multifocal electroretinogram (mfERG) decreases in myopia. A recent study indicates that the flash ERG is also reduced with increased axial length.

Axial length: An underestimated endophenotype of myopia

Medical Hypotheses, 2010
Myopia is a major threat for vision health across the world. Around 1 in 4 in the West and over 3 in 4 in the East are suffering from this common eye disorder. It is a complex trait affected by both genetic and environmental determinants. Axial length is an essential man-made parameter generated from ocular biometric components.

Axial Length Measurement

Eye & Contact Lens: Science & Clinical Practice, 2015
To compare axial length measurements taken on the handheld Micro Medical Devices (MMD) PalmScan with those taken with the Carl Zeiss Meditec IOLMaster.Sixty subjects had IOLMaster performed by a single operator to measure axial length in both eyes. Subjects then had axial length measurements taken by a different single operator with the MMD device ...

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 ...
