We developed a new system to measure thevolume of subretinal fluid in retinal detachment.We used B-scan ultrasonography coupled with thestandard video system. The ultrasound probe wasrotated by 180 degrees in front of the eye withretinal detachment. The scanned images wererecorded on the video tape. The recorded imageswere chosen and printed at regular intervals to beprocessed to allow caliculation of subretinal spacein successive ultrasound sliced images. Finally, thetotal volume of subretinal fluid was calculated asthe sum of partical volumes. The error between theactual and the measured volume was 3.74±2.96%(mean±standard deviation). Our system forquantitation of subretinal fluid appears to be ofclinical value.
