Objective: To analyze and summarize the clinical and imaging signs, diagnosis and treatment of primary orbital varix.
Method: 218 cases of primary orbital varix in 20 years were analyzed.
Results: Positional proptosis was the primary sign. Ultrasound examination showed that a characteristic well-out-lined lesion with low or without reflection of sound appeared in the orbital fat when the internal carotid vein was compressed.
Conclusion: To recognize the characteristic imaging signs of orbital varix in ultrasound examination is valuable for the choice of treatment.
