Management of anterior chamber dislocation of dexamethasone implant.

Purpose: To report dislocation of dexamethasone implant (Ozurdex®) into the anterior chamber and to discuss intervention options.

Design: Interventional case report.

Methods: An 89-year-old woman presented after Ozurdex® implant injection for chronic cystoid macular edema secondary to idiopathic intermediate uveitis.

Driving strategy alters neuronal responses to self-movement: cortical mechanisms of distracted driving.

We presented naturalistic combinations of virtual self-movement stimuli while recording neuronal activity in monkey cerebral cortex. Monkeys used a joystick to drive to a straight ahead heading direction guided by either object motion or optic flow. The selected cue dominates neuronal responses, often mimicking responses evoked when that stimulus is presented alone.

Cortical neurons combine visual cues about self-movement.

Visual cues about self-movement are derived from the patterns of optic flow and the relative motion of discrete objects. We recorded dorsal medial superior temporal (MSTd) cortical neurons in monkeys that held centered visual fixation while viewing optic flow and object motion stimuli simulating the self-movement cues seen during translation on a circular path. Twenty stimulus configurations presented naturalistic combinations of optic flow with superimposed objects that simulated either earth-fixed landmark objects or independently moving animate objects.
