Abstract The patient in this report exhibited the characteristic visual field loss that occurs with end-stage primary open angle glaucoma. Visual field testing revealed only small islands of vision remaining in the inferior visual field. This field loss resulted in the patient adopting an abnormal eye and head posture while trying to view acuity targets. Management consisted of the use of specially designed charts to determine the magnitude and axis of the prism required to relieve the patient's eccentric fixation position and stabilize searching eye movements. These new charts provide a more efficient method of determining prism needed when using the prism relocation technique. Each chart has a certain Snellen acuity level when held at 33 cm. The charts range in acuity levels from 20/30 to 20/300. Thus, it can be used to plot areas of clear vision and/or distorted vision for those patients unable to see the central dot or squares on the Amsler grid.
