schielen
Schielen, medically known as strabismus, is a condition in which the eyes do not align and point at the same object. The misalignment can be latent (phoria) or manifest (tropia), and can be constant or intermittent. In practical terms, one eye may drift inwards (esotropia), outwards (exotropia), or one eye may be higher or lower than the other (hypertropia or hypotropia).
Causes include imbalances or weakness of the eye muscles, refractive errors (notably uncorrected hyperopia), congenital factors,
Diagnosis is made by an ophthalmologist or optometrist through a comprehensive eye exam. Tests commonly used
Treatment depends on type and age. Corrective glasses address refractive error, and occlusion therapy (patching) treats
Prognosis is better with early detection and consistent treatment; many patients achieve good alignment and binocular
Epidemiology: Strabismus affects an estimated 2–3% of children; onset is usually in early childhood and is more
