Abstract

Many surgeons have used the technique of reattachment of the inferior oblique muscle to the scleral exit site of the inferior temporal vortex vein for 14.0 mm inferior oblique muscle recession. We studied the anatomical location of the scleral exit site of the inferior temporal vortex vein to determine whether we could use this site as a landmark for this technique. We examined 65 eyes in 2 to 13 year-old patients in which the location of the inferior temporal vortex vein was exposed during operation. We measured the axial length before operation and the cord length from the lateral point of the insertion of the inferior rectus muscle to the scleral exit site of the inferior temporal vortex vein. The locations of the inferior temporal vortexveins ranged widely from 7.5 to 14.0mm, the average of 9.89 +/-1.53 mm. It had no correlation with age (r=0.14) or axial length (p=0.13). Therefore, further study will be needed to confirm whether the scleral exit site of the inferiortemporal vortex vein can be a good landmark for the 14.0mm inferior oblique muscle recession.
