A synoptophore is an instrument for diagnosing imbalance ofeye muscles and treating them by orthoptic methods!

The instrument used to diagnose an imbalance of eye muscles is a synoptophore. It is used to treat the imbalance by orthoptic methods.

Only those with the name Seymore.

It is a piece of equipment used by orthoptists who specialize in dealing with eye squints and binocular single vision. The synoptophore can help to measure the angle of the squint present i.e how big it is and you can measure the angle in different position of gazes. it cam also be use to measure vertical and torsional deviations. Motor and sensory fusion can also be measure along with stereopsis (3D) vision .

First the patient's IPD is set by keeping your head straight and aligning the patient's eyes with the white line on the eyepieces. To measure the angle of deviation the tubes are moved in towards you if it is an inward deviation and move the tube away from you to measure a outward deviation in degrees. For sensory and motor fusion the tubes are converged and then diverged until the patient cant see the image as single .
