Aim: To study postoperative residual vertical deviation and abnormal head posture (AHP) after surgical treatment for congenital superior oblique palsy (SOP). Method: Children with both SOP and AHP who underwent extraocular muscle surgery for correction of AHP were recruited. The patients received complete ophthalmic and orthopaedic examinations. Residual AHP was classified according to severity...

The paper describes a 3-layered architecture for the control of the stereoscopic eye-saccade system of a stereo-camera head 1 mounted on an autonomous vehicle. The 0-level is a proportional feedback controller providing a microsaccadic 2 control for eye movements enabling the head to foveate and track targets but requiring iteration through the vision system with the attendant computational ove...

The recently published paper by Rankin et al. [1] ‘‘Iris recognition failure over time: The effects of texture’’ is paradoxical because in fact no changes over time were demonstrated, either in the iris patterns or in the system performance. The authors measured iris recognition performance using ‘‘local and non-local dipole and tripole’’ methods of iris feature extraction proposed by Sun et al...
