| A 25-year-old male presented himself to our outpatient department with increasing non-painful swelling below the medial canthus of the right eye since six months. |
| The eye movements were monitored by electrodes placed superorbitally and over the outer canthus of the left eye. |
| When he examined Halstead's eye, he found the eyestone near the outer canthus, and near it the irritating bit of wheat beard. |
| When the canthus takes a little angle or sinus out of the eye. |
| And there canthus was killed, while he was trying to drive off sheep, by a stone which a herdsman threw. |
| The speculum is opened to its full width without undue strain on the canthus and is kept in position by tightening the screw. |
