Summary The infant cases in 25 years of orthoptic practice have been selected for review. They comprise 750 infants among 5,497 patients seen by a single examiner during the period, 1952–1976. For the purpose of comparison, the review has been divided into three main time spans and has been analysed in relation to initial presentation treatment and results. A serious delay between onset and presentation has been documented, with evidence of recent improvement. Such delay is shown to be quite unwarranted and its elimination offers opportunity for major improvement in results. Results in large angle strabismus have shown no improvement over the period, in spite of improving techniques of diagnosis and treatment, but very considerable improvement in overall results has accompanied a marked fall in the proportion of large angle strabismus. This is attributed to earlier detection of strabismus while the angle is still small and intermittent and, to a lesser extent, to improved methods of treatment involving less use of glasses and surgery. The sensitive period for human binocular extinction is shown to taper off above the age of two years.
