Penalization treatment of amblyopia: a follow-up study of two years in older children

Penalization therapy for strabismic amblyopia is indicated in the group over six years of age. Good visual acuity of 6/12 or better was achieved and maintained at least for two years in 74% of the 38 cases reported. Deep amblyopia of 6/60 or less is no contraindication to treatment, success being achieved in 50% of this group. It seems that previous occlusion treatment diminishes the rate of success. Close supervision during the treatment is mandatory to assure the desired use of the amblyopic eye.
