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...

Quantel Optimis Fusion Puts Safety First

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...

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...

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...

Fixation disparity measurement

The authors evaluate different procedures looking at point zero, fixation disparity (FD) and motor fusion amplitude in order to calibrate the measurement of FD with Ogle’s apparatus with the overall goal to create a standardised measurement of the FD curve...

Results of surgery in a case of FMNS

The authors present the effects of the tenotomy and reattachment procedure on a patient with accommodative strabismus and fusion maldevelopment nystagmus syndrome (FMNS) who did not require strabismus correction. The ocular motility study of this patient allowed the opportunity to...

Simultaneous vs. alternate PCT disparity in XT

The authors quantified the relationship between simultaneous prism and cover test (SPCT) and alternate prism and cover test (APCT) alignment in patients with measures at the same visit after surgery for exotropia. This was a retrospective study of 955 patients...
