Abstract
To measure the possible differences in monocular detection time of a threshold visual acuity stimulus (recognition time RT) between patients with small-angle and large-angle strabismus. The authors hypothesized that alternating strabismus patients may have a significant advantage in maintaining a small-angle deviation, as a large-angle deviation would require longer RT in the moment the deviated eye takes up fixation. It can be speculated that the extension of re-fixation movement, obviously shorter in small-angle strabismus patients, is the main factor responsible for longer RT occurring in large-angle strabismus patients.File in questo prodotto:
