[18] Von Noorden found that 75% of 51 untreated patients showed progression over an average follow up period of 3.5 years while 9% did not change, and 16% improved.[19]. The lack of randomized controlled Observation: can be an option for patients who are well-controlled and asymptomatic with good binocular fusion. Eye choice for acquisition of targets in alternating strabismus. 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. He specializes in cataract and refractive surgery, micro-invasive glaucoma surgery, ophthalmic lasers, dry eye disease, diabetic retinopathy, and ocular trauma. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. For inferior oblique overaction with a significant V-pattern, the inferior oblique muscles may be weakened at the time of horizontal surgery. For this reason, they are rarely used for long-term management. Strabismus, or hypertropia, is a condition when one or both of the eyes are not properly aligned. Furthermore, each staff speaks at least 3 or 4 languages, including English, Italian and French. Abroms AD, Mohney BG, Rush DP, Parks MM, Tong PY. In childhood strabismus, exotropia is most frequently seen with intermittent exotropia and convergence failure in the first decade of life. Intermittent exotropia, which occurs occasionally, may only need to be monitored. Common sense approaches may help to control intermittent exotropia. A randomized trial comparing part-time patching with observation for children 3 to 10 years of age with intermittent exotropia. 1 Of these, approximately 25% present with exotropia, 2 most commonly intermittent distance exotropia (IDEX). Incidence and types of childhood exotropia: a population-based study. Govindan M,Mohney BG,Diehl NN,Burke JP. 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. Stathacopoulos RA, Rosenbaum AL, Zanoni D, et al. If the eyes are misaligned more often than they are straight, surgery on the eye muscles may be recommended to realign the eyes. Long-term results of the surgical management of intermittent exotropia. Part time patching of the non-deviating eye may convert an intermittent exotropia to a phoria by treating suppression and amblyopia. Often, exposure to bright light or photography may elicit eye closure of the non-dominant eye. London 1929, Bailliere, Tyndall and Cox. Sun - relax). Some have proposed the use of alternate day, alternate eye patching, but this generally works best in young children to regain control. Do people with exotropia see normally? Gnanaraj L, Richardson SR. A new classification of the motor anomalies of the eyes based upon physiological principles together with their symptoms, diagnosis and treatment. 4 = Exotropia > 50% of the exam before dissociation, 3 = Exotropia < 50% of the exam before dissociation, 2 = No exotropia unless dissociated, recovers in > 5 seconds, 1 = No exotropia unless dissociated, recovers in 15 seconds, 0 = No exotropia unless dissociated, recovers in < 1 second (phoria). Ing MR, Nishimura J, Okino L: Outcome study of bilateral lateral rectus recession for intermittent exotropia in children. Congenital or infantile exotropia is an outward turning of the eyes from birth or early infancy. 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. A total of 136 IXT patients (aged from 7 to 17 years) who had Arch Ophthalmol 1994;112:1349-1355. Fair Control: Patient blinks or refixates to control the deviation after disruption with cover testing. Apart from accommodation, we also offer several amenities to make your stay at Hostel Lombardia comfortable and memorable. Were your destination hostel whenever you visit Lombardy for study, vacation or even business. 2006 Sep; 14(3): 147150. Correction of refractive errors: Refractive errors can impair fusion and result in a manifest deviation. The natural history of surgically untreated intermittent exotropia-looking into the distant future. Conclusion: An essay on the nature and the consequences of anomalies of refraction. A thorough history should be obtained with regard to the age of onset, frequency of deviation, duration, and whether the deviation is increasing in frequency and/or duration. Restarting the eye exercises may help the symptoms go away Recession-Resection Procedure: Another option is a unilateral lateral rectus recession with medial rectus resection. 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. 8600 Rockville Pike 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. Pathophysiology of exodeviation. Am Ortho J 1988;38:81-93. Trans Am Ophthalmol Soc (XCV): 1997:433-452. Ophthalmology. Costenbader FD. Am J Ophthalmol. According to Donders, this constant under-stimulation of convergence may cause an exodeviation to develop. Am Orthopt J. Mohney BG, Holmes JM.
