[Oculomotor surgery in Parinaud's syndrome]

The authors report the result of surgery on a case of Parinaud's syndrome with a torticollis chin down of the Alajouanine type (the flexion of the head was used to allow an elevation of the eyes; from this position, depression was possible). A Fadenoperation on both medial recti aimed to suppress the convergence spasms. A resection of both superior recti aimed to substitute for the flexion of the head. The results clearly showed that it is possible to improve the oculo-motricity in a gaze palsy by substituting surgery for the compensatory reflexes. A Fadenoperation which does not destroy the previous parallelism in the primary position is a good indication for any convergence spasm.
