title: [Soft contact lenses with black center for occlusion treatment of amblyopia with excentric fixation and latent normal retinal correspondence (author's transl)].
abstract: Soft contact lenses with a central black zone 6.5-8 mm in diameter were used for occlusion treatmnt in nine cases of severe amblyopia with excentric fixation, incurable by direct occlusion or pleoptics. All the patients, aged between five and 14 years, had latent normal retinal correspondence. The new principle of this treatment is to interrupt only bifoveal retinal rivalry but not the existing binocularity of peripheral retinas. Therefore, an existing angle of squint has to be corrected by prisms. After treatment lasting five to 18 months one case had normal vision, four had sufficient visual acuity to cope with daily reading requirements, while improvement was insufficient in four cases. Treatment is continuing.
