Title: Application of color doppler blood flow imaging (CDFI) in the study of hemodynamics of retinal and choroidal rupture
Abstract: Objective To determine the changes of hemodynamics caused by retinal and choroidal rupture. Methods CDFI was applied to determine the flow parameters of the ophthalmic artery (OA), central retinal artery (CRA) and posterior ciliary arteries (PACs) of the affected, by retinal and choroidal rupture, and unaffected eyes. The peak systolic velocity (PSV), end diastolic velocity (EDV), pulsation index (PI) and resistance index (RI) were measured. Results There was a significant difference (P0.05) between the affected by the retinal and choroidal rupture and unaffected eyes of PSV, EDV, PI and RI in the CRA and PACs. No significant difference (P0.05) was observed in the OA of the affected eye by the retinal and choroidal rupture in comparison with the unaffected. Conclusion The flow velocity in the CRA and PCAs of the affected eye by retinal and choroidal rupture was reduced comparing to that of the unaffected eye, and also the RI was increased. CDFI is used for determining the changes of the flow velocity and RI which serves as an important indicator for the diagnosis, treatment and the prognostic value of ocular injury.
