Axial Length and the Hischberg Test

Optometry and Vision Science, 1978
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 mean value, 24 prism diopters

Axial Length and Proliferative Diabetic Retinopathy

Optometry and Vision Science, 2012
To determine the correlation between axial length and diabetic retinopathy (DR) in patients with diabetes mellitus for 10 years or more.This study was a prospective, observational, cross-sectional study. Patients with diabetes for 10 years or more were included. We excluded eyes with any other significant ocular disease or any prior intraocular surgery,

AXIAL LENGTH IN PATIENTS WITH DIABETES

Retina, 1999
To investigate the relationship between axial length and retinal involvement in patients with diabetes.A total of 157 consecutive patients with diabetes underwent biometry. The patients were divided into three groups, according to retinopathy: 44 without retinopathy, 37 with background retinopathy, and 76 with proliferative retinopathy.

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 Changes

2013
The biometric changes of the human eye with lowered intraocular pressure (IOP), like those observed after glaucoma surgery, have been investigated by in vivo studies. Leydolt et al demonstrated IOP-dependent axial eye length changes in human eyes. An axial eye length decrease of 2 μm/mm Hg with short-term reduction of IOP was observed.

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.

Variation of multifocal electroretinogram with axial length

Ophthalmic and Physiological Optics, 2003
AbstractIntroduction: 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. The aim of this study was to investigate the variations in the first‐order response (K1) and the first slice of second‐order response (K2.1) across ...

Serial axial length measurements in congenital glaucoma

American Journal of Ophthalmology, 2001
To illustrate the utility of axial length measurements in the management of congenital glaucoma.Interventional case series. Twelve eyes of six consecutive patients with congenital glaucoma were followed with serial axial length measurements. The axial growth patterns were compared with the normal growth curve.Eight (66.7%) of 12 eyes had initial axial ...
