Blurred vision on the left side of both eyes after cerebral infarction can be recovered after treatment, but it may be more difficult to recover if the scope of cerebral infarction is large or the treatment is not timely. The cause of blurred vision after cerebral infarction may be that the lesion site is in the occipital lobe of the brain, and the occipital lobe infarction may cause blurred or impaired vision and visual field loss, and in severe cases, the patient may even lose his eyesight. For patients with cerebral infarction who have blurred vision, it is generally necessary to actively treat the primary disease, in the early stage of the onset of cerebral infarction, usually within 6 hours, can be taken in time to thrombolytic therapy, if the lesion is small, the symptoms produced are relatively small, so usually after the thrombolytic vascular re-circulation, blurred vision symptoms can be completely restored. However, if the patient misses the time window for thrombolysis, or if the infarction is large, it is usually difficult to recover completely. In this case, the patient should be treated actively, such as the use of antiplatelet aggregating drugs and lipid regulating drugs, such as aspirin, atorvastatin, etc. In addition, neurotropic drugs can be used to improve the neurotropic function. In addition, neurotrophic drugs, such as B vitamins and methylcobalamin, can be used to help improve the patient’s vision. Meanwhile, vision rehabilitation training can be carried out during the recovery period of cerebral infarction to help the recovery of vision function. If the above symptoms occur, please consult the doctor in time and follow the doctor’s instructions actively to avoid the sequelae.
