What To Do If Blurred Vision Is Caused By Cerebral Thrombosis

Blurred vision caused by cerebral thrombosis can often be linked to the formation of a blood clot in the occipital lobe, which is responsible for processing visual information. When this occurs, it can disrupt normal vision and lead to partial or complete visual impairment. If the patient arrives at a medical facility within 4.5 hours of symptom onset and there are no contraindications, thrombolytic therapy using alteplase is strongly recommended. This treatment helps dissolve the clot and significantly reduces the risk of long-term complications.

Time-Sensitive Treatment Options

Timing is crucial in the treatment of cerebral thrombosis. If the 4.5-hour window for alteplase has passed but the patient is still within 6 hours of symptom onset, urokinase may be used as an alternative thrombolytic agent. Although slightly less effective than alteplase, urokinase can still help restore blood flow and minimize brain damage.

Long-Term Management Beyond the Acute Phase

Once the 6-hour window has passed, the focus shifts to long-term management. In such cases, antiplatelet therapy with aspirin becomes essential to prevent further clot formation. Additionally, statin medications are prescribed to lower cholesterol levels, stabilize arterial plaques, and reduce the risk of future cardiovascular events. These medications play a crucial role in secondary prevention.

Diagnostic Evaluation and Advanced Treatment

Comprehensive diagnostic testing, such as head and neck CT angiography (CTA), should be performed as soon as possible to assess the condition of major cerebral vessels. This imaging technique provides detailed visualization of blood flow and helps identify any acute vessel narrowing or blockage.

If significant large-vessel occlusion is detected, endovascular therapy may be considered. This minimally invasive procedure involves the removal of the clot using specialized devices, offering a potentially life-saving intervention when performed promptly by an experienced neurointerventionalist.
