On external examination, a soft prominence was noted in the right medial canthus
A 24-year-old unemployed female presented to the ophthalmology service with a one-month history of a gradually enlarging, ulcerative lesion of the right lower and upper eyelids in the area of the medial canthus
Xanthelasmata palpebrarum are sharply demarcated, yellowish flat plaques that appear on the upper or lower eyelids, most often near the inner canthus
13) A simulation of epicanthic folds, a fold of skin extending from the eyelid over the inner canthus
of the eye.
The caruncle is located at the inner canthus
and represents a transition zone between the conjunctiva and the skin.
The lateral canthus
or retinaculum is not fully anchored to increase the lateral visual field.
Additional bipolar electrodes were placed at the outer canthus
of both eyes, also above and below the left eye to measure the electro-oculographic (EOG) activity.
Retro-reflective markers were placed on the right outer canthus
, right tragus, C7 and T12 spinous processes, anterior superior iliac spine, and greater trochanter.
Electrooculogram (EOG) activity was recorded at the outer canthus
and infraorbitally to the left eye.
- corner of the eye where upper and lower lids meet
Ocular artifact was assessed by electro-oculogram recording from the supra-orbit and external canthus
of the subject's left eye.
The following examples, drawn from the full range of Banville's fiction, and arranged alphabetically, give a representative idea of what the reader may encounter: 'adipose, blastomere, borborygmic, canthus
, flocculent, integument, nates, oedemic, pachydermous, pandiculation, popliteal, strabismic, strangury, villous'.
In unilateral placement, one electrode is placed midline at the vertex, and the other on the dominant hemisphere (the hemisphere controlling the dominant hand) on a line between the outer canthus
of the eye and the external auditory meatus.
5-cm vesicle was noted above the left canthus
By placing electrodes vertical offset from each outer canthus
, eye movements right, left as well as up and down can be viewed.
