Fusion vergence measures
The purpose of this study was to compare fusional vergence measurements between orthophoria, esophoria and exophoria and determine the strength of correlation between fusional vergence and angle of deviation. This was a cross-section study of 530 children aged six to...
Fusion amplitude with Bagolini glasses
The aim of this study was to determine whether there is a difference between the horizontal prism fusion amplitude measured with and without the Bagolini striated glasses (BSG) in 52 young adults. Subjects had a mean age of 21.06 years,...
Vertical disparity effects on horizontal fusion
This study was designed to investigate the effect of induced vertical disparity by prisms on horizontal fusional reserves at near distance. One hundred and seventy students were recruited and vertical disparity was induced by small vertical prisms of 0.5 and...
Postop improved fusion and stereopsis in IDEX
This study aimed to evaluate changes in binocular visual function in patients with different ages before and after surgery to explore the optimal timing of intermittent exotropia surgery. The study comprised 28 females and 25 males. Fifty-three patients were split...
Using fusion measures to guide strabismus surgery
In this study the authors targeted patients with non-accommodative decompensating distance esotropia with investigation of prior binocular single vision. Choice of target angle was based on the individual’s fusional amplitudes. The target angle aimed to be less than the distance...Optimus Fusion Trio
The Quantel Optimis Fusion combines traditional YAG photodisruption treatments and advanced SLT photoregeneration therapy in an integrated platform. The Fusion is a glaucoma, cataract and retinal laser in one, which can switch seamlessly from SLT to YAG mode, with a...
Saccadic measurements in intermittent exotropia vs fusional amplitude
5 June 2023
| Fiona Rowe (Prof)
The authors investigated the correlation between fusional convergence amplitude and saccades during the shift from exotropia to binocular fixation during the cover / uncover test. This was an observational study of 15 patients (six female, nine male) with intermittent exotropia....
Fusional vergence measurement
This paper reports a systematic review to address two objectives: 1, to compare the normative values of tests measuring fusional vergence; 2, to investigate sources of heterogeneity of prism accuracy. The review was conducted according to PRISMA guidelines with a...Binocular single vision (BSV)

EYE - General
Introduction In this article I will try to summarise some of the definitions, tests and assessments performed in the strabismus clinic to assess patient binocular potential. This is a key feature of strabismus assessment, especially in adults, and it will...
Mediation of vertical vergence
The authors hypothesised that if vertical vergence were mediated by vertical rectus muscles, then the eye that moves during a vertical fusion task would produce larger vertical vergence when abducted versus adducted. Similarly, if mediated by the oblique muscles then...
Testing fusional amplitude
The purpose of this study was to evaluate the effects of varied testing distance and order of testing on fusion amplitudes in subjects with normal eye examinations, along with impact of examination encouragement and subject level of alertness. Average age...
