You may hear about exercises suggested for treating some cases of intermittent exotropia, however, they have not been shown to effectively treat intermittent exotropia. Eye exercises Prisms (thick prismatic glasses to reduce how much the eye has to turn) A patch over the good eye or drops to make the strong eyes vision blurry (this forces the weaker eye to try to align and focus) Surgery on the eye muscles Vision correction is the first step in almost every strabismus treatment plan. Age is seldom the main determining factor for exotropia surgery. If a patient is nearsighted or has highastigmatism, keeping the glasses prescription up to date may help control the alignment. Introduction There is a high prevalence of intermittent exotropia and exophoria in myopic populations, and orthokeratology is one of the effective interventions to control myopia progression in children.

The exact reason people with intermittent exotropia close one eye in bright light remains unknown. In any case, when the eye is closed, the child cannot use both eyes together. 1977;84:689. Hatt SR, Mohney BG, Leske DA, Holmes JM. Intermittent exotropia, which occurs occasionally, may only need to be monitored. If significant superior oblique overaction and an A-pattern is present, one may consider a superior oblique weakening procedure at the time or horizontal muscle surgery. Running together of words or missing of the Patients and method: Eye exercises. Esotropia in infants vs. adults Infants with esotropia may have one eye that Ball Rolling: This bilateral activity encourages convergence. Before Prisms: base-in prisms can promote fusion but may reduce fusional vergence amplitudes. Prisms in the management of intermittent exotropia. [20]This system is based upon the concept of fusional convergence and divergence and relies on measurements of the distance and near deviations.

A total of 136 IXT patients (aged from 7 to 17 years) who had Over-minus lenses: This technique is based on the principle that stimulating accommodative convergence can reduce an exodeviation. WebSometimes, intermittent exotropia stays mild or goes away on its own. Furthermore, each staff speaks at least 3 or 4 languages, including English, Italian and French. WebScore: 4.1/5 (42 votes) . Ophthalmol. Normal distance stereoacuity usually indicates good control with little or no suppression. 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. "I have noticed some changes in my daughter's eyes, one in particular. Eye exercises work best for smaller amounts of eye drifting. The angle of the exodeviation measures greater at distance than near by 10 prism diopters but this difference becomes minimal after 60 minutes of monocular occlusion or measurement of near angle with +3.00 diopter lenses. Does overcorrecting minus lens therapy for intermittent exotropia cause myopia? You may have to physically train your eyes to move in coordination with games and other tools. Comprehensive Ophthalmologist. 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. Conclusion: Exotropia may occur from time to time (intermittent exotropia) or may be constant. Buck D, Clarke MP, Haggerty H, et al. this randomized clinical trial study to determine the effect of partial patch therapy on the deviation control of children with intermittent exotropia. Yonsei Med J 1987:28:326. Heterotropic rectus extraocular muscle pulleys simulate oblique muscle dysfunction. 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. Caltreider M, Jampolsky A: Overcorrecting minus lens therapy for treatment of intermittent exotropia.

Lee SY, Hyun Kim J, Thacker NM. Often, exposure to bright light or photography may elicit eye closure of the non-dominant eye. A randomized trial comparing part-time patching with observation for children 3 to 10 years of age with intermittent exotropia. Strabismus, or hypertropia, is a condition when one or both of the eyes are not properly aligned. The opinions regarding their efficacy are controversial. If you see the X shape in the strings before or after the bead you're focusing on, practice focusing both of your eyes onto the bead. David Felsted, DO. 1971. 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. The hostel is organized, clean and gives value for money. Intermittent exotropia (IXT) is the most common type of strabismus in China, but the best treatment and optimal timing of intervention for IXT remain controversial, particularly for children with moderate IXT who manifest obvious exodeviation frequently but with only partial impairment of binocular single vision. More usually means good but not better. In addition, the natural history of intermittent XT has not been rigorously studied and, anecdotally, some cases resolve without surgery. Part-time patching and pencil push-ups can improve intermittent exotropia control in pediatric patients. Grading the severity of intermittent distance exotropia: the revised Newcastle Control Score. However, although heredity appears to play a role in exodeviations, the etiology of this disorder is thought to be multifactorial. Spencer RF, Tucker MG, Choi RY, McNeer KW. [ 1] Occlusion: Patching the dominant eye or alternate patching of either eye is suggested to interrupt the process of suppression and to reduce the progression of the exotropia. Medial Rectus Resection: Bilateral medial rectus resections are thought to be useful for the treatment of the convergence insufficiency type of intermittent exotropia because of the increased effect of this surgery at near. Over time, the deviation can remain stable, resolve or progress, however patients maintain normal retinal correspondence and good binocular function when they are ortho. WebExercises have been suggested for treating some cases of intermittent exotropia. Eye muscle problems or misalignment of the eyes (Strabismus) can run in families.

Intermittent exotropia is a very common form of strabismus typically not associated with neurologic or systemic disease. Surgery is appropriate when exotropia is present for most of the patients waking hours, regardless of age. This ocular misalignment has two main types: esotropia and exotropia. 1990;110-287. Scores of 5 to 3 are based on a 30-second observation period. While it is possible for exotropia to become less frequent with age, most forms of exotropia do not resolve completely. Trans Am Ophthalmol Soc (XCV): 1997:433-452. The eyes usually are straight for reading or near work but wander for distance viewing. Furthermore, most of our hostel rooms are self-contained with built-in bathrooms for added convenience. In cases of permanent vision loss, surgery to straighten the eye is often an option. You may also meet your travel partner at our hostel. Multiple interventions, including strabismus surgery, patching, over-minus glasses, and prisms have been described; they have had varying success.41 Further advances in the etiology of this condition could lead to improved treatment options and outcomes. Convergence exercises may be helpful in patients who have a remote near point of convergence, or in whom poor fusional convergence amplitudes are demonstrated.

Assessing Control of Intermittent Exotropia. Burian HM, Spivey BE. Exotropia in an eye with poor vision is called sensory exotropia. This entity is also named distance exotropia, divergent squint, periodic exotropia, or exotropia of inattention. Here are some tips on what to bring with you on, Are you concerned about the environmental impact of your electronics? Intermittent exotropia comprises about 75-90% of the cases of exotropia and is usually preceded by a stage of exophoria. The condition may also be inherited. Female predominance in intermittent exotropia. 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. Strabismus develops in approximately 5% of developmentally normal children. 2,3 Non-surgical exotropia treatment If exotropia is constant, an eye doctor may recommend: Prescription eyeglasses to correct any refractive error Placing a patch over the stronger eye to strengthen the weaker eye Epub 2009 Jul 15.

WebCan exotropia be fixed in toddlers? 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.
