To develop a Supine SD-OCT system for imaging pediatric patientsin the operating room (OR).
A Zeiss S5 OPMI (Carl Zeiss Inc, Germany) stand was modifiedto accept a motorized X-Y adjustment system and a stepper-basedZ-motion mechanism designed to provide fine adjustments andto secure a 4th generation hand-held SD-OCT probe (BioptigenInc, USA) to a goniometric cradle. The system has 5-degreesof freedom: X, Y, Z to align the pupil at the intersection pointof the rotational axes; yaw and roll to select the area imagedon the retina. Bench top testing was performed using a modeleye. Thus far, 7 pediatric patients were imaged in the OR underan IRB approved protocol.
The system was able to acquire high quality volumetric SD-OCTimages of the posterior pole in all patients. The mounting ofthe probe on the positioning system facilitated the alignmentand selection of specific area of interest. On average, positioningand acquisition of one dataset took less than 2 minutes.
The Supine SD-OCT system provided precise placement of the SD-OCTprobe and facilitated perioperative imaging of pediatric patientsin the OR.Support: DOD Grant DAMD-W81XWH-09-1-0675; BioptigenInc; Florida Lions EyeBank; NIH Grant P30EY14801;Researchto Prevent Blindness; Henri and Flore LesieurFoundation
