Anomalies of Binocular Movements
- 222 Downloads
When all of the extrinsic muscles are completely relaxed by suppression of nervous excitation, the eyes take a position of equilibrium by action of various forces or pressures that are exerted on them. This position of anatomical rest is observed only in a cadaver, or as a result of paralysis. The lines of vision then diverge (their divergence angle can be as much as 10°), which is explained by the disposition of the orbits.
