This will make your affected eye work harder while the vision in your stronger eye is blurred. Patients and method: More usually means good but not better. Glasses, prisms (if the angle of exotropia is small), patching therapy, orthoptic vision therapy, exercises can help reduce or control the outward-facing eye in some children. A randomized trial comparing part-time patching with observation for children 3 to 10 years of age with intermittent exotropia. Part time patching of the non-deviating eye may convert an intermittent exotropia to a phoria by treating suppression and amblyopia. Fair Control: Patient blinks or refixates to control the deviation after disruption with cover testing. 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. 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. 1981:1814-18. Govindan M,Mohney BG,Diehl NN,Burke JP. Restarting the eye exercises may help the symptoms go away WebConvergence exercise into three types based on the difference between the are useful for convergence insufficiency but for most distance and near deviations: (1) basic, where the In a multi-center, randomized clinical trial comparing these 2 surgical approaches in children aged 3 to 10 years with intermittent exotropia, no difference in surgical success was identified, 63% versus 54% in the recess/resect group.25 Similar results have been reported in younger children.26 A retrospective study found that recess/resect had slightly better outcomes, although it did concede that the surgeons preference likely influenced the results.27 The argument to support bilateral symmetric surgery is to avoid inducing horizontal incomitance and prevent the palpebral fissure narrowing sometimes associated with horizontal rectus muscle resections. Current concepts in the management of concomitant exodeviations. Although this traditional Burian classification has been widely cited, Kushner has proposed a reclassification or expansion to include categories such as tenacious proximal fusion, high AC/A ratio, low AC/A ratio, proximal convergence, and pseudo-convergence insufficiency.13, There have been multiple methods described to quantify control of patients with intermittent exotropia. Intermittent exotropia is a condition in which there are times when one eye has drifted outwards, and other times when the eyes are straight. Eye muscle problems or misalignment of the eyes (Strabismus) can run in families. WebAdults, as well as children, can have intermittent exotropia. WebBackground: Intermittent exotropia (IXT) is a common form of childhood exotropia, accounting for about 5090% of all the exotropia and affecting about 1% of the general Introduction: Certain factors are associated with exotropia, including genetics and health conditions. No refunds are provided without prior approval from the AAPOS Executive Office. Prisms: base-in prisms can promote fusion but may reduce fusional vergence amplitudes. Parks MM.

Exotropiaor an outward turning of the eyesis a common type of strabismus accounting for up to 25 percent of all ocular misalignment in early childhood. Surgical experiences with two-muscle surgery for the treatment of intermittent exotropia. Some have proposed the use of alternate day, alternate eye patching, but this generally works best in young children to regain control. In: Manley D ed.

Bookshelf The assessment of control of intermittent exotropia is essential to obtain a baseline evaluation as well as to monitor deterioration and progression of intermittent exotropia. In recent studies, the reported success rate in all types of intermittent exotropia have been about 60-70%.[28][29][30][31]. If you only find white patches, let your child decorate the patch with their choice of stickers.

At home: The parents may be told to keep a chart noting the control of deviation at home in terms of the percentage of waking hours the manifest deviation is noted at home. Crossref Certain factors are associated with exotropia, including genetics and health conditions. Pineles SL, Ela-Dalman N, Zvansky AG, Yu F, Rosenbaum AL. 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. Botulinum toxin management of childhood intermittent exotropia. Sometimes, convergence insufficiency comes back after successful treatment with exercises. Chia A, Seenyen L, Long QB.

American Academy of Ophthalmology. Prescribing 2.0 to 4.0 diopters of myopic correction to the refraction of children with intermittent exotropia is thought to induce convergence, promote fusion, and decrease the angle of the eye misalignment. Intermittent exotropia is a very common type of eye misalignment. One or both eyes turn out toward the ear occasionally. Only one eye turns out at a time while the other eye points straight forward. The cause of this condition is not known. Most experts believe that the brain of affected patients has trouble controlling the position of the eye. Esotropia (in-crossing of the eyes) is much more common than exotropia in infants. A randomized trial comparing part-time patching with observation for children 3 to 10 years of age with intermittent exotropia.

Regarding preoperative target, some have advocated for targeting the deviation after 1 hour of monocular occlusion or for the largest angle of exotropia ever measured.29 Kushner has recommended having the patient fixate in the far distance (eg, mile) to potentially uncover a larger angle of deviation and target that deviation.30, Predictors of success following surgery for intermittent exotropia are less clear, although a small retrospective study suggested that performing surgery before a patient is 7 years old, or before the duration of the patient's exotropia has reached 5 years, may be associated with better long-term sensory outcome.31 Another retrospective study with long-term outcomes (10 years) found that patients with anisometropia, lateral incomitance, and immediate postoperative undercorrection were at highest risk for poor outcomes following surgery for intermittent exotropia.32 Approximately 1 in 5 children with intermittent exotropia have a second surgery, although as many as 50% had suboptimal sensorimotor outcomes.33, Botulinum toxin has been used for strabismus since the 1990s.

Intermittent exotropia comprises about 75-90% of the cases of exotropia and is usually preceded by a stage of exophoria. J Pediatr Ophthalmol Strabismus 1998;35:146-148. The clinic control score is described below, scored 0 to 5 with 5 being the worst control. Intermittent exotropia (X(T)) is one of the most common type of strabismus in children as well as adults, especially in the Asian and South Asian populations.14 In these populations, it has been estimated that the prevalence of exotropia can be up to 718.5 times higher than that of esotropia, out of which the most common type is X(T) accounting for Feeling sick or having a fever may cause the intermittent exotropia to temporarily occur more frequently.
