Accommodative strabismus

Accommodative strabismus is a type of strabismus where the eyes do not align properly due to issues with the focusing mechanism of the eyes. This condition is often associated with refractive error, particularly hypermetropia (farsightedness), and is most commonly observed in children.

Causes

The primary cause of accommodative strabismus is an uncorrected refractive error, typically hypermetropia. The child's attempt to overcome this refractive error and focus on objects can lead to an over-convergence of the eyes, resulting in strabismus. Other factors that may contribute to the development of this condition include genetic predisposition, certain systemic diseases, and prematurity.

Symptoms

The most noticeable symptom of accommodative strabismus is the misalignment of the eyes, which may be constant or intermittent. Other symptoms can include headache, eye strain, difficulty reading, and double vision. In some cases, the child may close or cover one eye to relieve the symptoms.

Diagnosis

Diagnosis of accommodative strabismus involves a comprehensive eye examination by an optometrist or ophthalmologist. This examination typically includes a visual acuity test, a refraction test to determine the presence of refractive error, and an examination of the eye's alignment and focusing ability.

Treatment

Treatment for accommodative strabismus primarily involves correcting the underlying refractive error. This is typically achieved through the use of eyeglasses or contact lenses. In some cases, vision therapy may be recommended to improve eye coordination and focusing. In severe cases, or when other treatments are ineffective, eye surgery may be necessary.
