ABSTRACT
Attention to the powerful effects of pollutant exposure on chemically sensitive individuals not only will aid treatment of the various fixed-named eye diseases that may result in select cases but also will often altogether eliminate their development. The eye has two significant types of innervation. The first is via the cranial nerves, and the second is through the autonomic nerves. Several cranial nerves may be involved in pollutant injury to the eye. The trochlear nerve innervates the superior oblique muscle, which primarily rotates the eye outward and downward. Injury to this nerve will cause eye movement dysfunction. Pollution-induced stimulation of the posterior part of the hypothalamus induces vasoconstriction, heat production, increased metabolism, and pupillary dilatation. Some technology that enables the reader to analyze more objectively the damage to the eye caused by chemical exposure as well as the involvement of the ANS has now evolved.
