[Dynamic visual functions in patients following the removal of craniopharyngiomas].

The author analyzes the time course of neuro-ophthalmologic symptoms in patients with craniopharyngiomas in the immediate and late periods after tumor removal by microsurgical techniques. The early stage of visual disturbances was found the most favorable as regarded vision recovery. In patients with later stages of visual disturbances vision recovery is possible and more likely in the late period after surgery. Conservative therapy is advisable in the postoperative period, transcutaneous electrostimulation of optic nerves may be recommended as well. Repeated interventions for progressive tumor growth may not only prevent further deterioration of vision, but may even contribute to its improvement.
