When the visual areas in the occipital lobes are destroyed, especially early in life, and the person appears to be without conscious vision, subconscious visual awareness ("blind sight") may still exist because the occipital lobes receive increased visual input from the superior collicular (retinal-tectal) visual pathways (Giaschi et al., 2003; Leh, Johansen-Berg, & Ptito, 2006).
Anterior collicular fractures typically result from supination external rotation mechanisms and appear as a transverse oblique fracture on the AP (anterior-posterior) view.
Tornetta (24) showed that fixation of anterior collicular fractures does not necessarily confer medial stability to the ankle.
Posterior collicular fractures begin in the intercollicular groove and extend superiorly and posteriorly.
Fixation of collicular fractures can be accomplished with a small fragment compression screw when the fracture fragment is transverse.
Close attention should be focused on anterior collicular fractures, as they may represent an associated deep deltoid ligament disruption that will not be addressed with fixation of the collicular fragment.
In this case, the peripheral cue would automatically activate a collicular local motor program for a saccade in the direction of the stimulated position.
