Another method used for prescribing for patients with intermittent strabismus, particularly for those who have difficulty with fusion in free space, is Calorosos Residual Vergence Demand (RVD).7 RVD criteria look at the direction and size of the deviation and determine how much residual vergence demand the patient should have after prescribing relieving prism.

It increases accommodative convergence and also increases fusional divergence to maintain fusion of the stationary target. Although this seems like a very basic requirement for prism use, it can present an obstacle if not done appropriately or at all. 632.
