Dark spokes that radiate outward like spokes in a wheel. They are commonly referred to as Radii Solaris (rays of the sun) and are most commonly seen in the head zone.
There are two types; minor (There are two types of minor radials – neither of which interrupt the structure of the collarette) and major radials, the latter interrupting the structure and dynamics of the collarette.
Significance: The impact of radial furrows is determined by their size and location. Small examples that are confined inside the collarette are referred to as minor radials.
They indicate potential intestinal or stomach disorders including increased gastric tension and intestinal colic. The client could have a history of eating disorders, complaining of gastric pain associated with anxiety. (Yellow arrow)
Minor radials that commence outside the collarette and protrude via the humoral zone into the ciliary zone (blue arrow) are specific to the topographical reflex tissue, suggesting the tendency for spastic conditions. These are permanent features in the iris and the conditions represented will be part of this person’s personal pattern. It is useful for you to discuss ways of dealing with times of stress and anxiety so the client can be less symptomatic at such times.
Understanding Radial Furrows
Major radials that commence inside the pupillary zone, extending through the collarette into the ciliary zone (Red arrow) have the most significance as they suggest disturbed autonomic nervous system regulation and altered circulation of the blood and deep lymph in the adjacent tissues. This can be associated with irritable bowel symptoms in addition to autonomic nervous system disturbance for the organs and tissues in which they terminate.
Radial furrows located in the head zone indicate an increased likelihood for the client to experience headaches. They are considered to be a dark sign and can be psychologically significant according to their location.
