Eye scan therapy for astigmatism.

Two earlier papers

(Astigmatism as a Function of Visual Scan, and Head Posture, Elliott

A New Model of Functional Astigmatism, Elliott Forrest, JAOA, Volume
52, Number 11, November 1981, pp 889-897.)

introduced a new model of functional astigmatism. The investigation
that led to the model indicated a relationship exists between
meridional eye scanning habits and the formation of functional
astigmatism. The present paper reviews the model and describes a
clinical study involving the prescribing of specific eye scan therapy
on a meridional basis. The results demonstrate that therapy involving
eye scanning procedures has a positive effect on the control and
reduction of astigmatism.

Visual conditions of symphony musicians.

Harris P.

Professional symphony musicians work in a very stressful environment
which requires them to remain in asymmetric postures for long periods
of time. The maladaptations (i.e., astigmatism and anisometropia) made
as a result of the stress and the asymmetric postures are
investigated. Forrest's astigmatism theory is restated and related to
the musician with clinical data to support the theory. Stress
management through imagery for the musician is discussed. A study is
also discussed which shows that good sight readers in music use a
fundamentally different eye scan pattern to read music from the
pattern that they use to read written language.
