Base-in prisms can be used to neutralize the deviation to stimulate fusion, or to overcorrect the deviation in the hope of reducing the deviation,38 but this treatment modality is not commonly used today. The acquired forms of exotropia include intermittent exotropia, sensory exotropia, and consecutive exotropia (exotropia that develops after surgery to treat crossed eyes). Use different colored beads so your eyes can tell which bead you're focusing on.

A comparison of this technique to standard lateral rectus recession showed lower rates of undercorrection in the augmented group.28, Two common concerns that arise regarding surgical planning regardless of the approach are the appropriate preoperative deviation to target as well as the predictors of success. A prolonged alternate cover testing should be used to suspend tonic fusional convergence. Transient intermittent exotropia is sometimes seen in the first 4 - 6 weeks of life and, if mild, can resolve spontaneously by 6 - 8 weeks of age. Families are usually concordant for either esotropia or exotropia, but families with both forms have been reported. In childhood strabismus, exotropia is most frequently seen with intermittent exotropia and convergence failure in the first decade of life. This ocular misalignment has two main types: esotropia and exotropia. For inferior oblique overaction with a significant V-pattern, the inferior oblique muscles may be weakened at the time of horizontal surgery. Ocular motility is typically full and the deviation is comitant. A nonrandomized, case-controlled study of children aged 3 to 144 months with intermittent exotropia showed similar results to those in prior surgical reports when they received injections of 2.5 units of Botox into each of the lateral rectus muscles.34 In this study, 69% of patients injected with Botox were orthophoric 12 to 44 months following the intervention.

Br Orthopt J. Patch Test - The patch test is used to control the tonic fusional convergence to differentiate pseudo-divergence excess from true divergence excess and to reduce the angle variability. Intermittent exotropia is the most common type of strabismus. A full sensorimotor evaluation should be completed with strabismus measurements taken at distance and near and in all directions of gaze, which can provide insight into the subtype of intermittent exotropia, first described by Burian in 1966.11,12. Some patients or family members notice the exotropia more when the patient is tired or daydreaming.

Conclusion: In a prospective observational study of 183 children between 3 and 10 years old who had intermittent exotropia, but for whom surgery was not considered necessary, the probability of deterioration at 3 years (constant exotropia or decline in stereopsis) was 15%.19 Similarly, a retrospective study of patients aged 5 to 25 years found that without surgery, the angle remained stable in 58%, improved in 19%, and worsened in 23%;20 this was similar to previous reported values.21, Apart from observation, many treatments have been described to address intermittent exotropia, although there is a lack of clarity regarding criteria for intervention and optimal intervention.22,23, Before considering which type of surgery to perform for intermittent exotropia, it is useful to consider the surgical goals for the surgeon and the patient. Esotropia can be monocular (involves one eye) or binocular (involves both eyes). Thanks to all authors for creating a page that has been read 74,191 times. [11][12], In a patient with uncorrected myopia, less than normal accommodative effort is required during near vision thus causing decreased accommodative convergence. 1977;84:689.

Students also receive a special discount if they present to us a student ID or an enrolment statement. Exodeviations. Orthoptics: Convergence exercises such as pencil push-us or computer orthoptics may be helpful in patients with convergence insufficiency who have a remote near point of convergence, or in whom poor fusional convergence amplitudes are demonstrated. Sometimes, convergence insufficiency comes back after successful treatment with exercises. Control of the intermittent deviation can vary throughout the day.3,4, The etiology of intermittent exotropia is largely unknown,5 and the deviating movement shares features with normal divergent eye movements, but divergence tone may exceed convergence tone in these patients, correlating with hypometric adduction saccades.6,7, Patients with intermittent exotropia are often asymptomatic, although children with the condition will occasionally close either eye, a symptom that may be exacerbated by bright light, giving the condition its alternate moniker, squint. Patients can also rarely report intermittent binocular horizontal diplopia or a sense of discomfort associated with eye deviation.

Include your email address to get a message when this question is answered. Exodeviations (from Greek , "exo" meaning "to exit" or "move out of) are either manifest (exotropia) or latent (exophoria). Eye exercises can also strengthen the muscles around the eye to improve alignment. In: Manley D ed. It can be found in every age group [See figures 1 and 2]. Variability of control in intermittent exotropia. A randomized trial comparing bilateral lateral rectus recession versus unilateral recess and resect for basic-type intermittent exotropia. Due to lack of a standard definition for a successful outcome, variability in classification systems, multiple treatment approaches, and a paucity of long-term data it is difficult to determine the true outcome of currently available treatments for intermittent exotropia.
