The terms "open lacuna" and "closed lacuna" are used in iridology to describe specific markings in the iris. These markings are not recognized or used in any legitimate medical context.
Lacuna is a term used to describe a small, white, or light-colored area in the iris. In iridology, these lacunae are thought to indicate areas of weakness or toxicity in the body.
* Open Lacuna: This term refers to a lacuna that is surrounded by a ring of darker tissue. It is believed to indicate a more serious health condition than a closed lacuna.
* Closed Lacuna: This term refers to a lacuna that is not surrounded by a ring of darker tissue. It is believed to indicate a less serious health condition than an open lacuna.
It's important to note that these claims have no scientific basis. There is no evidence to suggest that lacunae in the iris are correlated with any health conditions.
If you are concerned about your health, it is important to consult with a qualified medical professional, not rely on iridology.
