| Popis: | Purpose: To evaluate the early and late alterations in orbital blood flow parameters in eyes with severe eyelid swelling due to blunt trauma by using colour Doppler ultrasonography (CDU). Methods: Blood flow parameters in the ophthalmic artery (OA), central retinal artery (CRA), short posterior ciliary arteries (SPCAs) and central retinal vein (CRV) were examined by CDU in 62 eyes of 31 patients with unilateral blunt trauma and in 32 eyes of 32 normal subjects. Patients were examined within the first 5 days and at least 1 month after trauma. The traumatized eyes of patients were designated ‘trauma eyes’, non-traumatized fellow eyes were designated ‘fellow eyes’, and randomly chosen eyes of control subjects ‘control eyes’. Results: In the early phase, peak systolic velocity (PSV) and end diastolic velocity (EDV) in the OA in trauma eyes were statistically significantly higher than in both fellow eyes and control eyes: the p-values for the differences in PSV and EDV between trauma eyes and fellow eyes were p |
