The conclusions drawn from his ijtermittent are:. It is also indicated if a child has significant exotropia when reading or viewing near objects or if there is evidence that the eyes itnermittent losing their ability to work as a single unit binocular vision. In patients in the visually mature age group with an overcorrection of more than 20 prism diopters, nonsurgical measures may be tried till weeks after which a re-surgery should be planned if the deviation persists.
Patients with a residual exotropia over 15 prism diopters in the first postoperative week will probably not improve and many will require additional surgery. Small children who won’t wear sunglasses may be offered a hat with a brim, such as a baseball cap, to shield the eyes from the sun, thereby limiting the need to squint.
As mentioned before adults who develop intermittent exotropia after age 10 years usually present with diplopia and in these patients orthotropia in the immediate postoperative period is desirable. Evaluation and management of intermittent exotropia. Adjustable suture techniques are helpful in cooperative patients 24, Conflicts of interest There are no conflicts of interest. Does watching too much television or playing too many video games make exotropia worse?
Exotropia (divergent squint)
The previous studies have found both birth weight and gestational age to be independent risk factors for strabismus. Journal List J Pediatr Neurosci v. Divergemt Exotropia — Straight. Refractive error is associated in a severity-dependent manner to the prevalence of esotropia and exotropia. Postoperative diplopia is used to stimulate the development of fusional vergences and stabilize postoperative alignment.
Management of Intermittent exotropia: Post-operative evolution of the planned initial over-correction in intermittent exotropia: When a child requires surgery, the procedure is usually performed before the child attains school age. Can J Ophthal ; The left eye is then occluded for a s period and the intermlttent to re-fusion is similarly measured.

This abnormal position is determined by anatomic and mechanical factors such as orientation, shape and size of the orbits, size and shape of globes, volume and viscosity of reterobulbar tissue, functioning of the eye muscles as determined by their insertion, length, elasticity anatomical and structural arrangement and condition of fascias and ligaments of the orbits 5.
divergejt The Newcastle Control Score: Observations on the surgical overcorrection of childhood intermittent exotropia. Among other benefits, binocular vision is necessary for normal depth perception, or “3-D vision”.
Natural History imtermittent Intermittent Exotropia – The natural history of intermittent exotropia remains obscure due to lack swuint longitudinal prospective studies and only a few retrospective studies of untreated intermittent exotropia. In this case, the eye with reduced vision is unable to work together with the other eye, and therefore, the poorly seeing eye may have a tendency to drift outward. It is better to wait weeks before re-operating on the residual exotropia.
