Synoptophore has been used as the standard tool for generations together. This instrument is the best choice for a modern-day Orthoptic clinic. It is considered ideal for the assessment and treatment of disorders related to ocular motility. Synoptophore is known for its capacity for performing outstandingly and offering the most comprehensive binocular vision assessment.
Understanding Synoptophore
The ophthalmic instrument is used widely by opticians. It compensates for the angle of squint and facilitates stimuli to be presented to both eyes instantaneously. The instrument helps with diagnosis of eye muscle imbalance and treatment via orthoptic methods.
History
Interestingly, the Synoptophore design has endured vast changes over the years. In the year 1838, the first stereoscope was constructed by Sir Charles Wheatstone. Later in the early 20th century, Claud Worth manufactured the Amblyoscope for efficient evaluation and stimulation of binocular vision.
M.C. Maddox was the first to develop slides for early devices to help accurate evaluation of the extent of simultaneous perception. The device also helped with the accurate measurement of the suppression area.
Originally based on the above-listed instruments, the Synoptophore evolved from its job of measuring deviation angles and treating binocular anomalies. In the year 1929, it has also used plenoptic after the first patent of Clement Clarke.
The Uses
The device is utilized to examine the possibility of binocular function with presence of manifest squint. Optician use this in the case of children (age 3 years and up) for detecting suppression and abnormal retinal correspondence.
Functioning of Synoptophore
The device comprises of 2 cylindrical tubes and LCD Visual Tester. These are available with the mirrored right-angled bend. It also comes equipped with A +6.50 D lens in both eyepieces which sets the testing distance to approx six meters optically.
Ease of Use
It is easy to use Synoptophore. It can check misalignments simultaneously. A versatile and accurately designed Synoptophore will always provide precise measurement. One can expect accuracy in just a single, easy checkup.
A Synoptophore is used for Standard measurements and treatments involving assessment of deviation related to objective and subjective angle. It is also ideally suited for examining abnormal retinal correspondence, vergences (horizontal and vertical), cyclophoria, and hyperphoria.
Binocular Grades Estimation
The syoptophore works towards providing an accurate estimation of binocular vision.
- Grade 1(simultaneous perception)
It is tested by two dissimilar (not mutually antagonistic pictures).
- Grade 2 (Fusion)
This is associated with the testing the ability of the two eyes to create a composite image from two similar images. In this case, each image is incomplete in a minor different detail.
- Grade 3 (Atereopsis)
The test is done to assess capability to obtain an impression of depth via superimposing 2 pictures of same object taken from slightly varying angles.
Detection of Normal and Abnormal Arc
This is done via determining the subjective and objective angles of squint in a patient. In case of a patient
