Purpose To compare the peripapillary retinal nerve fiber layer (RNFL) thickness of amblyopic and fellow eyes. We hypothesized that the RNFL of the amblyopic eye may be thinner. Design Prospective, cross-sectional, observational case series. Methods Optical coherence tomography of the peripapillary RNFL thickness of amblyopic and fellow eyes was performed in 37 patients 7 to 12 years of age (mean age 卤 standard deviation, 9.2 卤 1.5 years) with unilateral strabismic, anisometropic, or combined-mec...

The treatment of unilateral congenital cataract remains a challenge because form deprivation early in life leads to amblyopia. Visual outcomes after congenital cataract extraction have improved dramatically with earlier surgery, greater attention to optical correction of the aphakia, and part-time occlusion therapy of the phakic eye. A published review of unilateral congenital cataract studies between 1988 and 2004 found that 88% of patients with primary intraocular lens implantation achieved 20...

Amblyopia is defined as the unilateral or bilateral underdevelopment of visual acuity without any organic abnormality of the globe. Amblyopia is generally detected in 2-5% of the general population,1 and the current known causalities of amblyopia are abnormal binocular interaction and the deprivation of vision and accurate images. This deprivation can be due to starismus, anisometropia, a difference in refractive error, ptosis, or other abnormalities. Amblyopia occurs during the period when the ...

PURPOSE. To study the distribution of optic disc, cup, and neural rim size by ocular and demographic variables in a population-based sample of 6-year-old children. METHODS. The Sydney Childhood Eye Study examined 1765 of 2238 eligible 6-year-old children (78.9%) from 34 randomly selected Sydney schools during 2003 to 2004. Comprehensive standardized eye examination included cycloplegic autorefraction, optical biometry and "fast optic disc" scans performed using optical coherence tomography. RESU...

: Duane retraction syndrome is a congenital incomitant strabismus caused by dysinnervation of the medial and lateral rectus muscles. Patients with unilateral Duane syndrome (80-90% of cases) who exhibit a fixation preference tend to prefer the unaffected eye. We describe 8 patients with unilateral Duane syndrome who prefer the affected eye. The most frequent associated ophthalmic finding was decreased vision in the unaffected eye from anisometropia and/or amblyopia. An additional associated find...

OBJECTIVE: To compare the thickness of the retinal nerve fiber layer (RNFL), the macular volume, and the macular thickness of the amblyopic eye with those of the non-amblyopic eye in patients with unilateral strabismic amblyopia using optical coherence tomography (OCT). PATIENTS AND METHODS: OCT was performed for 14 patients with unilateral strabismic amblyopia who had no neurologic disease. Nine male and 5 female patients, whose ages ranged from 5 to 18 years, were enrolled in the study. The RN...

This prospective study was performed to measure the macular and the peripapillary retinal nerve fiber layer (RNFL) thicknesses using optical coherence tomography (OCT) in patients with anisometropic amblyopia. Thirty-one patients with hyperopic anisometropic amblyopia were included. The macular retinal thickness and the peripapillary RNFL thickness were measured using OCT. The mean refractive error was +3.71 diopters (D) and +1.00 D, the mean macular retinal thickness was 252.5 碌m and 249.7 碌m, ...

The potential amblyogenic effect to the sound eye of atropine combined with optical penalization is powerful, and frequent patient monitoring is necessary when using this therapy. We report two cases of amblyopia developing in the previously sound eye as a result of noncompliance during atropine therapy combined with optical penalization. Both cases required active treatment to correct the reverse amblyopia. Vision returned to normal in one patient, while the second patient was lost to follow-up...

PURPOSE. To test the hypothesis that eyes with amblyopia may have thicker retina, retinal nerve fiber layer thickness (RNFLT) was investigated in patients with unilateral amblyopia. METHODS. Thirty-eight patients with unilateral amblyopia were studied. Among them, 20 patients had amblyopia with strabismus and 18 had refractive amblyopia without strabismus. Nineteen of 38 had anisometropia of 2.0 D or more. In addition, 17 patients with anisometropia of 2.0 D or more but without amblyopia were en...

Anisometropia represents a unique example of ocular development, where the two eyes of an individual, with an identical genetic background and seemingly subject to identical environmental influences, can grow asymmetrically to produce significantly different refractive errors. This review provides an overview of the research examining myopic anisometropia, the ocular characteristics underlying the condition and the potential aetiological factors involved. Various mechanical factors are discussed...

Purpose: To investigate the interocular symmetry of optical, biometric and biomechanical characteristics between the fellow eyes of myopic anisometropes. Methods: Thirty-four young, healthy myopic anisometropic adults (鈮 1 D spherical equivalent difference between eyes) without amblyopia or strabismus were recruited. A range of biometric and optical parameters were measured in both eyes of each subject including; axial length, ocular aberrations, intraocular pressure (IOP), corneal topography an...

Purpose Measurement of distance stereoacuity may be useful in assessing strabismic patients, especially those with intermittent exotropia. We developed the Distance Randot Stereotest as an easily administered quantitative test for distance stereoacuity in children. By using a prototype, we reported testability, validity, and normative data. Here we report normative and validity data for the final, commercially available version of the test. Method We administered both the Prototype and the Final...

Background : Diagnosis of amblyopia in preverbal strabismic patients is frequently made by binocular fixation preference (BFP) testing. The reports on reliability of BFP are equivocal. This study evaluated the reliability of BFP testing in patients with horizontal strabismus. Materials and Methods: This prospective observational study included patients with manifest, horizontal, comitant deviation >10 prism diopter (PD). Inter-eye acuity difference (IEAD) was calculated by converting Snellen vis...
