Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]
Efforts must first be made to identify and treat the underlying cause of the problem. Treatment options include eye exercises, [2] wearing an eye patch on alternative eyes, [2] [24] prism correction, [26] [24] [27] and in more extreme situations, surgery [5] [28] or botulinum toxin. [29]

People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence ...
When not in use, the device's batteries are plugged into a power outlet to be re-charged. Side effects.
