THE instrument of choice

For generations, the Clement Clarke Synoptophore has been the standard instrument of choice for the busy Orthoptic clinic. It is ideal for the assessment and treatment of ocular motility disorders by reliably performing the most comprehensive binocular vision assessment available today.

Assess all grades of Binocular Single Vision

Comprehensive measurements

All of the Synoptophore models allow standard measurements and treatments. They enable the assessment of simultaneous perception, fusional amplitudes and gross stereopsis even in the presence of abnormal retinal correspondence, or horizontal, vertical and torsional ocular misalignment.

Assess all grades of Binocular Single Vision

Simultaneous perception

First grade of BSV, Simultaneous Perception (SP) is easily assessed using two dissimilar images and adjusting the controls of the Synoptophore until the images are superimposed or one image is suppressed. 

Assess all grades of Binocular Single Vision

Fusional amplitudes

The second grade of BSV, Sensory (SF) and Motor Fusion (MF) is measured using two similar images with incomplete controls. The eyepieces of the Synoptophore are then converged and diverged until either control disappears or the image splits into two.

Assess all grades of Binocular Single Vision

Stereopsis (disparity sensitivity)

The third grade of Binocular Single Vision (BSV), Stereopsis, can grossly be quantified using two disparate images to indicate depth perception and provide a stereoacuity value. 

Assess all grades of Binocular Single Vision

Cyclotorsion (Circumducton)

Complex binocular vision anomalies, such as cranial nerve palsies can be fully-assessed using the ambidextrous controls of the Synoptophore. It will establish binocular potential in the presence of horizontal, vertical and torsional components.

Three different models

The most comprehensive binocular vision assessment available today

All Clement Clarke Synoptophore models allow standard measurements and treatments. They enable the assessment of simultaneous perception, fusional amplitudes and gross stereopsis in all positions of gaze.

Three different models

2001 model - The most comprehensive Synoptophore

All the standard measurements and treatments are possible on this instrument including assessment of the angle alpha, the objective angle, abnormal retina correspondence, cyclophoria, hyperphoria and horizontal vertical vergences. An automatic flashing unit allows each eye to be stimulated alternately or simultaneously. Manual flashing switches and independent dimming rheostats are provided as standard. After images are achieved by using high-intensity halogen light sources and condensing systems. A pair of removable Haidinger's Brushes motor units are included in the 2001 model. This allows the user to employ pleoptic techniques to assess and treat eccentric fixation and abnormal retinal correspondence.

Three different models

2002 - Ideal for daily-use

This model of Clement Clarke Synoptophore combines all the features of the 2001 model, with the exception of the Haidinger's Brushes device. It is the standard instrument for the busy clinic and ideal for the assessment and treatment of patients needing orthoptic care or management.

Three different models

2003 - Entry-level assessment

The entry level Synoptophore provides all the standard measurements and treatments, including; assessment of the angle alpha, the objective angle, abnormal retina correspondence, cyclophoria, hyperphoria and horizontal vertical vergences. Manual flashing switches and independent dimming rheostats are provided as standard.

Three different models

Complimentary slides

An extensive range of complimentary hand-crafted slides are available, whose images are easily understood and recognised by patients. The slides fit all Synoptophore models and come in different colour-coded series, for use in different tests and treatments

Regulatory affairs

Setting the standard

The range of Clement Clarke Synoptophores are consistently updated to meet stringent international regulatory standards. The models have routinely undergone rigorous safety, Electromagnetic Compatibility (EMC) and environmental testing.
