The authors report the experience of so‐called penalization methods (optic and drug inhibition and favouring) in the treatment of squint amblyopia in a material of 23 children who had proved resistant to conventional occlusion therapy of a mean duration of 8 months. The ineffective occlusion therapy had been performed continuously in three and periodically in 20 of the patients. The mean age of the patients was 5 years, and the mean duration of squinting was 4 years before penalization therapy was instituted. The unsuccessful occlusion was done by adhesive tape and in the majority of cases was given up by the patients and parents; in only three cases was it the doctor or orthoptist who decided to abandon the procedure. In our Clinic, occlusion therapy is rarely given up by the patient or the parents, so the present group represents exceptional cases. In 17 of the 23 patients a considerable visual gain was obtained, the mean visual acuity in the amblyopic eye increasing from 6/24 to > 6/9. Visual improvement was not obtained in patients in whom conventional occlusion therapy had been carried out correctly and permanently for a long time before being given up. The penalization therapy lasted for an average of 10 months and was easy to carry through (only three patients gave up).
