Esotropia

Esotropia is a form of strabismus in which one or both eyes turns inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a 'cross-eyed' appearance. It is the opposite of exotropia and usually involves more severe axis deviation than esophoria. Esotropia is sometimes erroneously called 'lazy eye', which describes the condition of amblyopia—a reduction in vision of one or both eyes that is not the result of any pathology of the eye and cannot be resolved by the use of corrective lenses. Amblyopia can, however, arise as a result of esotropia occurring in childhood: In order to relieve symptoms of diplopia or double vision, the child's brain will ignore or 'suppress' the image from the esotropic eye, which when allowed to continue untreated will lead to the development of amblyopia. Treatment options for esotropia include glasses to correct refractive errors (see accommodative esotropia below), the use of prisms and/or orthoptic exercises and/or eye muscle surgery. The term is from Greek eso meaning 'inward' and trope meaning 'a turning'. Esotropia is a form of strabismus in which one or both eyes turns inward.

The term is from Greek eso meaning 'inward' and trope meaning 'a turning'. Concomitant esotropia – that is, an inward squint that does not vary with the direction of gaze – mostly sets in before 12 months of age (this constitutes 40% of all strabismus cases) or at the age of three or four. Most patients with 'early-onset' concomitant esotropia are emmetropic, whereas most of the 'later-onset' patients are hyperopic. It is the most frequent type of natural strabismus not only in humans, but also in monkeys. Concomitant esotropia can itself be subdivided into esotropias that are ether constant, or intermittent.
