title: Watchmakers' glaucoma.
abstract: We present the first reported case of an 'apparent' unilateral glaucoma in the eye used by a watchmaker with a monocular loupe. We hypothesise that it was caused by the pressure from the orbicularis oculi muscle contraction associated with holding it in position for long periods of time. We believe that users of this kind of optical instrument should avoid wearing it always in the same eye or using it for long periods of time and should be monitored closely by routine ophthalmic examinations.
