CRAO Caused By Thrombus
Thrombus-induced central retinal artery occlusion (CRAO) is a relatively rare cause of this condition. It occurs when a thrombus, or blood clot, forms in the blood vessels due to systemic vasculitis, an autoimmune condition where the body mistakenly attacks its own blood vessels. Vasculitis leads to inflammation in the blood vessels. Patients who develop CRAO as a result of thrombosis need to be diagnosed and treated promptly to prevent further complications.
Symptoms and Signs of Central Retinal Artery Occlusion (CRAO)
Recognizing the symptoms and signs of central retinal artery occlusion (CRAO) is crucial in seeking prompt medical attention. This condition is characterized by sudden and severe vision loss that occurs without any associated pain. It is important to note that the extent of vision loss varies depending on the level of blockage in the retina.
One of the key indicators of CRAO is a unilateral visual field defect, meaning that the loss of vision is limited to one eye. In some cases, individuals may experience a sudden and complete blurring of sight in the affected eye, which can serve as a red flag for central retinal artery occlusion. Another potential sign is a gradual and progressive loss of sight in one eye over the course of a few weeks.
It is worth mentioning that the symptoms of CRAO can sometimes resemble those of other health conditions. Therefore, it is crucial to consult with your primary healthcare provider to receive an accurate diagnosis and appropriate treatment.
