Colour Doppler examination of early and late orbital haemodynamic changes in eyes with eyelid oedema due to blunt trauma

Abstract

ABSTRACT.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 < 0.001 and p = 0.001, respectively, while the p-values for the differences in PSV and EDV between trauma eyes and control eyes were p = 0.002 and p = 0.019, respectively). No other blood flow parameters obtained at the first examination in all groups were statistically different. In the late phase, PSV in the OA in trauma eyes was found to be higher than that in both fellow eyes and control eyes, but the difference was significant only between trauma eyes and fellow eyes (p = 0.028). End diastolic velocity in the CRA was statistically significantly lower in fellow eyes than in control eyes (p = 0.046). No other blood flow parameters in any vessels examined in fellow eyes and control eyes were statistically significantly different during the study period. Conclusion: Blood flow velocities detected by CDU are increased in the OA in eyes with eyelid oedema due to blunt trauma and some of these changes may persist for up to 1 month. This effect seems to be a consequence of trauma-induced hyperaemia in the orbital soft tissues rather than an expression of traumatic choroidal vasculopathy.

Orbital venous malformation: percutaneous treatment using an electrolytically detachable fibred coil

“…1997). Lymphangiomas are considered as malformations without flow, but combined venous−lymphatic malformations also exist (Harris 1999; Alp et al. 2006).…”

“…Some authors claim that a distinction between venous and lymphatic vascular malformation is artificial and prefer to treat according to clinical findings (Wright et al 1997). Lymphangiomas are considered as malformations without flow, but combined venous)lymphatic malformations also exist (Harris 1999;Alp et al 2006 Extensive sclerosing using an arterial, venous or direct percutaneous approach bears the risk of sclerosing material migrating to the cavernous sinus, producing massive inflammatory reactions and venous congestion in the orbit. In addition to thrombophlebitis and thromboembolism, complications include optic nerve injury, scarring, haemorrhage, and urticaria to severe anaphylaxis (Arat et al 2004).…”

“…Increased PSV and EDV in the OA have been also described after eyelid oedema resulting from blunt trauma. This effect was presumed to be a consequence of trauma‐induced hyperaemia in the orbital soft tissues (Alp et al. 2006).…”

“…Bunun yanında Rainer ve ark., santral retinal arter akım hızı ve pulsatil amplitüdde cerrahi öncesi ve sonrası arasında bir değişiklik olmadığını bildirmişlerdir 6. Alp ve ark., sağlıklı olgularda katarakt cerrahisi sonrası oftalmik ve santral retinal arter kan akımında herhangi bir değişiklik gelişmediğini belirtmişlerdir 7. Türk ve ark., kan basıncı normal hastalarda katarakt cerrahisinin oküler hemodinami üzerine bir etkisinin olmadığını bildirmişlerdir.…”
