Consecutive exotropia after correction of hyperopia, Spontaneous consecutive exotropia in childhood, Clinical risk factors for the development of consecutive exotropia: a comparative clinical study, Characteristics and surgical outcomes of consecutive exotropia of different etiologies. The postoperative changes of angle of deviation were calculated. When the patients had not been initially operated in our centre, all efforts were made to know which procedure had been performed to treat the esotropia. -, J AAPOS. Hyperopia was considered significant when ≥4.00 D and anisometropia when ≥1.00 D. The following features were reported: age, gender, age of onset of esotropia, age of esotropia surgery, number of surgeries and chosen procedures, the refractive anomalies (significant hyperopia or anisometropia), an adduction deficit, a convergence insufficiency, a vertical deviation or oblique dysfunction, time of relapse, that is, the time between the esotropia surgery and the consecutive exotropia onset, angle of exodeviation (in PD). The authors declare no substantial contribution provided by another person, no assistance of medical writing experts, no participating authors who would not meet the full authorship criteria.

In adults who develop strabismus, double vision sometimes occurs because the brain has already been trained to receive images from both eyes and cannot ignore the image from the turned eye.
Ophthalmologe. The incidence of the consecutive exotropia seems to increase in studies with a long-term follow-up.9,21 The retrospective design of our series allowed including patients with established consecutive exotropia who underwent their esotropia surgery more than 20 years ago. Some of us advocate early surgery, whereas others advocate waiting as long as possible. Using linear mixed model analysis, the exotropic shift across time was higher in the consecutive exotropia group relative to the controls (P < 0.001).

Clipboard, Search History, and several other advanced features are temporarily unavailable. “The surgery rate of 17 percent was lower than what most of us think of as the number of kids who need surgery. The angle of deviation of consecutive exotropia was ≤20 prism dioptres (PD) in 39%, 21-40 PD in 39% and ≥ 40 PD in 22%, related to amblyopia (p = 0.028), and to high hypermetropia (p = 0.05). The patients were considered as amblyopic when they presented either a difference of two lines or more between the eyes (named ‘relative’ amblyopia) or a best corrected visual acuity of the weaker eye of less than 20/32 (named ‘deep’ amblyopia).

This compartmentalization was suggested by a selective compartmental intramuscular innervation23 and by the contractile changes of the superior and inferior compartments of the medial recti during convergence and adduction efforts.24,25 Moreover, it has been shown that this differential compartmental activity occurred in all extraocular muscles (recti and superior oblique) in vertical ductions in healthy subjects, and that all extraocular muscles contributed to the normal cyclovertical movements.26. doi: 10.1097/MD.0000000000021401. A second procedure had been performed for 20% of patients to correct a residual esodeviation. When is exotropia needed for surgery?

Several studies assessed the clinical and surgical risk factors for consecutive exodeviations with a high variability of the highlighted contributive factors. [Unilateral combined strabismus surgery to correct esotropia : Video article on recession of the medial rectus muscle and plication of the lateral rectus muscle]. The consecutive exotropia is a divergent ocular deviation which appears secondarily to an esodeviation. Outcomes of bilateral lateral rectus recession in treatment of recurrent exotropia after bilate... Postoperative Esotropia: Initial Overcorrection or Consecutive Esotropia? 108 patients who underwent BMR recession for esotropia between November 1996 and July 2010 were enrolled. 54 patients who required surgery for consecutive exotropia were compared to 54 controls whose angle of deviation showed less than five prism diopters of esotropia at all periods after BMR recession. Factors associated with atypical postoperative drift following surgery for consecutive exotropia. 2004;19(4):201-6.

Before Surgery Exotropia After Surgery. Our cohort of 74 patients allowed to highlight some of them and to assess their importance, such as the early onset of esotropia,2 the amblyopia,7–9 the convergence insufficiency,3,10 the adduction deficit,11,12 an asymmetric surgery,8 and the oblique muscles dysfunction.13 We found a strong influence of the amblyopia on the angle of the consecutive exodeviation. Risk factors for consecutive exotropia after esotropia surgery. The surgery cost depends on insurance coverage, and the risks and benefits of surgery vary from person to person.
