Strabismus

Abstract

Background: Strabismus is pathological deviation of one eye in relation to the other. Squinting can be inward, outward, upward, and downward and combinaton of these four types. There are many risk factors for developing strabismus: genetic factors, uncorrected refractive error, lower visual acuity at one eye at concomitant strabismus, and neuropathic and myopathic at nonconcomitant strabismus. Diagnosis is based on visual alignment, cover test, ocular motility, central fixation.Conclusions: Convergent strabismus is the most common form of strabismus, divergent strabismus is much less common and the ethiology for it stays unclear. Therapy for strabismus is primarily correction of refractive error, therapy of amblyopia and surgery if necessary.
