چکیده
The pulsed Doppler ultrasound allows quantitative evaluation of orbital vascular structures by measuring the VPS,VFD, IR, IP, TA, IA. Be valued B-mode, color Doppler and pulsed Doppler patients diagnosed by eye fundus of diabetic retinopathy. We evaluated12 patients. The ACR showed IR<0.701case, IR from 0.71 0.7912 cases and IR> 0.80 11 cases, in AO their patients showed IR<0.753 cases, IR from 0.76 to 0.805 cases and IR>0.8116 cases. The IR and TA of the ACR are increased and the valuesare related to the stage of DR, IP and VP Sare also increased, the A and VDF showed no change compared to the control group. The IR, IP, TA, VPS of the AO were increased, VDF decreased, IA shows no change compared to the control group, The assessment of the ACR and AO to determine changes in the pulsed Doppler related to diabetes. RESUMEN La ecografía Doppler pulsada permite la valoración cuantitativa de las estructuras vasculares orbitarias través de la medición de la VPS, VDF, IR, IP, TA, IA. Se valorará en modo B, Doppler color y Doppler pulsado pacientes diagnosticados por fondo de ojo de retinopatía diabética. Se valoraron 12 pacientes. La ACR demostró IR < 0.70 1 caso, IR 0.71 – 0.79 12 casos e IR >0.80 11 casos, en la AO los pacientes presentaron IR < 0.75 3 casos, IR 0.76 – 0.80 5 casos e IR >0.81 16 casos. El IR y el TA de la ACR estuvieron incrementados y los valores están relacionados con la etapa de la RD, el IP y la VPS también estuvieron incrementados, el IA y la VDF no mostraron variación en relación con el grupo control. El IR, IP, TA, VPS de la AO estuvieron incrementados, VDF disminuida, el IA no muestra variación en relación con el grupo control. La valoración de la ACR y AO permite determinar alteraciones en el Doppler pulsado relacionadas con la diabetes. PALABRAS CLAVE Retinopatía diabética, Doppler de ojo, índice de resistencia, índice de pulsatilidad, tiempo de aceleración, índice de aceleración, velocidad pico sistólica, velocidad flujo diastólica, Doppler pulsado.

Ocular blood flow velocities in patients with proliferative diabetic retinopathy and healthy volunteers: a prospective study.
BACKGROUND Diabetes affects the vascular ocular circulation. Colour Doppler imaging allows for simultaneous two dimensional anatomical imaging and Doppler evaluation of blood flow velocity; with this technique ocular blood flow velocity can be evaluated in normal and diabetic patients. METHODS A prospective study compared blood flow velocity in ocular vessels (ophthalmic artery, posterior cil...
