Intermittent Divergent Squint - Ophthalmology & Vision Research

Intermittent exotropia X(T) has an estimated prevalence ranging from 0.43–1.7% [1]. IXT is the most prevalent type of exotropia and has been reported to be more prevalent in females. The strabismus is  exacerbated when the child focuses on distant objects, is tired or daydreaming, and may be  accompanied by monocular  eyelid closure  in  bright  sunlight  (diplopia  phobia). Symptoms  include  headaches, eyestrain, blurred vision and occasional double vision. The frequency with which X(T) deteriorates to constant exotropia is  unclear. Intermittent  exotropia  is  subdivided  into  ‘basic’ and ‘distance’ subtypes. Reports suggest that some cases improve over time, some remain stable  and  others  deteriorate.
