Characteristics of saccadic intrusions
Primary fixation is never perfectly stable, but is frequently interrupted by slow drifts, microsaccades and saccadic intrusions (SI). SI are involuntary, conjugate movements which take the form of anExpand

Motor and sensory characteristics of infantile nystagmus
Background/aims: Past studies have explored some of the associations between particular motor and sensory characteristics and specific categories of non-neurological infantile nystagmus. The purposeExpand

Waveform characteristics in congenital nystagmus
Using infra-red oculography, electro-oculography and fundus video-recordings, waveform characteristics (amplitude, frequency, waveform shape and foveation) were examined in over 150 individuals withExpand

Visual loss and visual hallucinations in patients with age-related macular degeneration (Charles Bonnet syndrome).
PURPOSE The condition in which visual hallucinations (VHs) are solely associated with a visual impairment is termed Charles Bonnet Syndrome (CBS). The study was undertaken to investigate whether theExpand

Retinal slip velocities in congenital nystagmus
An analysis of waveform velocities was performed on 16 individuals with congenital nystagmus. The fast phases were shown to be saccadic in nature and their main sequence peak velocity wasExpand

Advances in the management of congenital and infantile cataract
Congenital and infantile cataracts produce deprivation amblyopia and can thus cause lifelong visual impairment. Successful management is dependent on early diagnosis and referral for surgery whenExpand

Oscillopsia and tolerance to retinal image movement in congenital nystagmus.
PURPOSE To determine the relationship between retinal image movement (RIM) and oscillopsia in subjects with idiopathic congenital nystagmus (CN). METHODS Eye movements were recorded using an IRISExpand

Modulation of saccadic intrusions by exogenous and endogenous attention
Primary gaze fixation in healthy individuals is frequently interrupted by microsaccades and saccadic intrusions (SI). The neural systems responsible for the control of attention and eye movements areExpand

Quick phase programming and saccadic re-orientation in congenital nystagmus
Horizontal single-step stimuli were presented to 19 subjects with congenital nystagmus (CN). When the stimulus jump was in the same direction as the waveform beat, spatial and temporal measurementsExpand
