Maddox Cylinder

The technique is considered more accurate. As part of the procedure, the patient focuses his gaze on the lamp. The light source should be at a distance of 5 m (for distance) or 33 cm (for close-up evaluation). The doctor puts a special frame on the patient, a prismatic compensator is installed in front of the left eye, and a Meddox cylinder is installed in front of the right eye. Horizontal phoria The cylinder is installed horizontally in the frame, the prismatic compensator - vertically. There is a vertical red line in front of the patient's right eye. The patient is with open eyes, he must tell which side of the light source is the red line.

The Maddox cylinder test is the most accurate method for diagnosing Heterophoria.

When passing the line directly over the lamp, the doctor diagnoses the absence of latent strabismus. The location of the line on the side of the cylinder indicates esophoria (deviation of the eyeball inward), if it is located on the opposite side, exophoria (deviation outward) is diagnosed.
