On December 9th, atropine was discontinued; on the 14th, the position of the eyes was still quite normal; on the 19th, permanent convergent squint of the left eye was present. Squint had never been observed in the child before. Bouble images were voluntarily announced without my having inquired for them, they were homonymous and moved further apart at both sides of the visual field.
