Axial Length and the Hischberg Test
American journal of optometry and physiological optic, 1978ABSTRACT Axial lengths of 30 eyes (15 subjects), measured by ultrasonography, ranged from 20.6–26.3 mm. Using a fixed light source, each eye was photographed as monocular fixation was changed over an 8‐deg range in 2‐deg steps. Hirschberg ratios obtained from the photographs show a low correlation with axial length (0.07), and the ...

Axial length in applanation tonometry
Journal of Cataract and Refractive Surgery, 2002To 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 ...

Axial length: An underestimated endophenotype of myopia
Medical Hypotheses, 2010Myopia 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.

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 Globe Length in Congenital Ptosis
Journal of Pediatric Ophthalmology & Strabismus, 2015Purpose: 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 Estimation in Strabismic Patients
Journal of Pediatric Ophthalmology & Strabismus, 1996ABSTRACT 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, 2006To 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 ...
