Stereograms - Open Bucket.
Used to improve fusional convergence amplitudes in orthoptic treatment of functional convergence insufficiency. Utilizes physiologic diplopia.
Adequate fusional convergence amplitudes will allow the patient to view a third image in the center of the card: a third bucket in the center of the card in depth.
These stereograms are printed on thin cards and are suitable to give to patients for home training purposes.
Packet contains 80 cards rather than the normal 100.
