Strabismus and binocular summation

The authors conducted a pilot study to investigate the effect of visual noise or background complexity on binocular summation in patients with strabismus. A target embedded in pixel noise was used. The study involved performance of a task detecting a...

Binocular summation with low contrast

The magnitude of binocular summation was investigated in normal control subjects using four different letter charts of varying type with fixed and variable contrast levels and spatial frequency to determine which tests most readily reveal binocular summation in normal subjects....

Binocular viewing amblyopia therapy

The authors compared conventional occlusion therapy for amblyopia with binocular viewing amblyopia therapy (MFBF) for effects on binocular vision and visual acuity. During MFBF the amblyopic eye perceives the target while the fellow eye perceives the background. Both eyes see...

Binocular training for amblyopia

The clinical effectiveness of binocular investigation for amblyopia was measured. The authors had previously unsuccessfully treated patients using occlusion and / or surgery. Patients were followed for an average of six months after cessation of treatment. The study included 22...

Binocular summation responses in strabismic amblyopia

A preliminary study was conducted to determine whether binocular summation (BS) in strabismic amblyopia is more decreased than in strabismus alone and whether strabismus surgery improves BS. The study included 15 strabismic amblyopes, 30 normal controls and 30 strabismic controls....

IXT control vs. binocular summation

The purpose of this study was to evaluate the relationship of BS scores with other current markers used for evaluating the control in preoperative intermittent exotropia (IXT) patients. Data was collected on stereoacuity, angle of deviation, Newcastle control score (NCS),...

Effect of oxygen levels on binocular summation of dark vision

Previous studies have reported conflicting results on the existence of binocular enhancement of dark vision. This study compares monocular and binocular absolute thresholds of dark adaptation in two different populations (healthy individuals and those with chronic respiratory insufficiency). The study...

The revolutionary Chronos Automated Binocular Refraction System with SightPilot® guided refraction software

Topcon Chronos is a complete digital refraction solution combining binocular objective autorefraction, keratometry and subjective refraction in a single device.

Outcomes with small aperture IOLs

This study aimed to compare the clinical outcomes following the implantation of an extended depth of focus small-aperture intraocular lens (IOL) (IC-8; AcuFocus, Irvine, CA) for presbyopia correction when implanted monocularly or binocularly. Visual outcomes, defocus curve, patient satisfaction, and...

Spot screener versus Grand Seiko measurements

The authors aimed to determine repeatability and reproducibility of refractive values and pupil size measured using the Spot Vision Screener and to compare its measurement values with the Grand Seiko autorefractor. This was a cross-sectional study of 22 healthy adults;...

A comparative evaluation of a new diffractive trifocal and EDOF IOLs

This study aimed to compare the outcomes of two diffractive trifocal intraocular lenses and one extended depth of focus (EDOF) intraocular lens (IOLs). This was a six month, single centred, prospective, randomised, comparative study in which patients who underwent routine...

Perceptual learning treatment for amblyopia

The authors previously conducted a feasibility study examining the potential benefit of a self-administered at-home use of a tablet-based perceptual learning (PL) game. Visual stimuli were presented in various orientations and spatial frequency in a game-play format. This study evaluates...
