Divergence excess DE is a type of intermittent exotropia IXT defined by a larger exodeviation at distance than at near. This case report explains the signs and symptoms of IXT and evaluation of a patient. Of the various treatment options, the case report focuses on management of IXT with overminus therapy. Advantages and disadvantages of other treatment options are also discussed. Intermittent exotropia IXT is the most common form of childhood exotropia 1, 2 with an incidence of



Ophthalmology and Visual Sciences. Intermittent exotropia is an exodeviation intermittently controlled by fusional mechanisms. Unlike a pure phoria, intermittent exotropia spontaneously breaks down into a manifest exotropia. Prevalence - Exodeviations are much more common in latent or intermittent form than are esodeviations.


Intermittent Divergent Squint in Prematurity and Its Neurophysiological Aspects

Intermittent distance exotropia is a deviation characterized by an exophoria at near fixation and manifest exotropia at distance fixation. There is normal binocular fusional vergence and stereoacuity at near fixation, but the eyes tend to diverge in bright sunlight, tiredness, day dreaming and the patient may close one eye in such circumstances. Prematurity is associated with numerous eye pathology, besides retinopathy of prematurity, amblyopia, refractive errors, it is also associated with a higher risk esotropia and exotropia. We report a case of a 5-year-old girl preterm and very low birth weight with an intermittent deviation of both eyes since three years. On her detailed ocular examination diagnosis of divergence excess intermittent exotropia with normal accommodative convergence to accommodation ratio was made.


Intermittent Distance Exotropia (IDEX)

Exotropia, or divergent squint, refers to an eye that turns or diverges outwards. Exotropia may occur from time to time intermittent exotropia or may be constant. You may only notice one particular eye drifting out, or it may be either eye that deviates, known as an alternating exotropia. These types of exotropia usually begin in early childhood. Congenital exotropia is more unusual, and often indicates poor vision or an ocular pathology. This outward drift, which occurs only in those moments of visual inattention, can be controlled when visual attention is refocused. The exotropia may occur rarely and result in few or no symptoms.
