After the surgery of pituitary tumor, the blurred eye is usually related to the occurrence of saddle region hematoma, intracranial hemorrhage, intraocular pressure changes and other factors after the surgery, and can be relieved by choosing medication and surgery according to the specific conditions. 1. Hematoma in the saddle area: if there is hematoma in the skull which has not been removed after pituitary tumor surgery, it can cause eye blurring after compression to the saddle area, and another surgery is needed to remove the hematoma. 2. Intracranial hemorrhage: some pituitary tumor patients are prone to intracranial hemorrhage after surgery, when the amount of hemorrhage increases, it may cause the symptom of postoperative xerophthalmia, which can be treated with medicines such as aminomethylcyclic acid and mannitol according to the doctor’s instruction. 3. Change of intraocular pressure: Pituitary tumor surgery requires injection of anesthetics, and anesthetics are more stimulating to the cranium and brain, which will easily lead to change of intraocular pressure, thus causing eye blurring. Generally speaking, no special treatment is needed for this situation, and the symptoms will be gradually reduced and return to normal after the anesthetic components are discharged from the body. If you have been suffering from blurred vision after pituitary tumor surgery, you need to consult a doctor in time to identify the cause of the blurred vision and take targeted treatment under the guidance of a physician.
