Study of haemodynamics changes of retinal detachment patients

Objective We evaluated the retrobulbar haemodynamics changes of retinal detachment patients using color Doppler ultrasound technique. Methods Color Doppler ultrasound were used to measure peak systolic velocity (PSV) ,end diastolic velocity(EDV) ,average velocity(AV) , resistance index (RI) and pulsation index (PI) of ophthalmic artery(OA),central retinal artery(CRA) and posterior ciliaries (PCA) in 60 retinal detachment patients of 62 rhegmat-ogenous eyes and also 58 normal control of 38 healthy eyes. Results The flow rates of ophthalmic artery( OA ) in retinal detachment patients had no difference compare with normal control( P 0.05). The PSV, EDV and AV of CRA and PCA in different retinal detachment patients all decreased( P 0.01 = but the PI and RI had no difference( P 0. 05) . The degree of decrease were relatived with the damaging degree of retinal detachment, but they had no difference( P 0.05). Conclusions The haemodynamics changes of retinal detachment have direct influence on microcirulation condition of retinal. This can provide significant foundations of retinal detachment pathological mechanism research and clinic phamic assisted therapy.
