Oculomotor paralysis in functional strabismus

Analysis of 800 strabismic children, in the out-patient follow-up, shows a frequency of congenital strabismus of 15%. In a great number of them, the causes were neurogenous. The anamnesis showed that 80 of them had a suffering at birth, and in 42 a defective neuropsychic evolution was found. 40 children were prematures and 30 had not the weight limit at birth. The strabismic deviation was larger than 15 degrees in 83% of the cases, and amblyopia was not frequent. Examples are given of 10 various observations of oculomotor pareses. The treatment was, generally, surgical and was applied early, before consolidation of the abnormal retinal correspondence.
