Abstract

Fifty-nine children (75 eyes) with organic amblyopia were investigated to know the distribution and incidence of the optic nerve or retinal lesion, the type of sensory strabismus, and the effect of occlusion therapy in organicamblyopia. Optic nerve lesion was found more frequently than retinal lesion as causes of organic amblyopia. Among these optic nerve lesions, optic nerve hypoplasia and tilted disc were most frequently found, and in the retinal lesion, ROP (retinopathy of prematurity: macular dragging), foveal dysplasia, and myopic degeneration were frequent.Thirty-nine of 59 children with organic amblyopia (66%)showed strabismus and 74.4% of them had horizontal deviation; 17 eyes had esotropia, and 12 eyes exotropia. No vertical eyeball deviation was found. Myopic anisometropia was accompanied in 19 cases. Better visual outcome was obtained after occlusion therapy in cases with tilted disc and ROP according to the degree of these lesions. However, there was no improvement in other cases. Authors suggest that fundus examination should be included in the routine ophthalmologic examination in chlidren with strabismus.
