| Definitions |
Dissociated vertical deviation (DVD) occurs when the level of illumination received by either eye is reduced sufficiently and as a result eye deviates progressively upwards, but reverts to its original position when the level of illumination returns to normally acceptable levels. It may sometimes be so asymmetrical as to be virtually unilateral and is associated with heterotropia usually of early onset. An incomitant tendency for an occluded eye to elevate and extort which resolves on uncovering. |
