DACRYOSTENOSIS Meaning and
Definition
-
Dacryostenosis is a medical condition that refers to the partial or complete obstruction or narrowing of the lacrimal (tear) ducts. The lacrimal ducts are tiny channels that transport tears from the eyes to the nasal cavity.
Typically, dacryostenosis is present in infants, specifically in newborns. The condition may develop due to various factors, such as a congenital malformation of the lacrimal system. In most cases, dacryostenosis affects only one eye (unilateral), but it can also occur in both eyes (bilateral).
The symptoms of dacryostenosis largely revolve around excessive tearing. Since the tear ducts are either partially or completely obstructed, the tears have difficulty draining from the eyes, resulting in a buildup. This buildup often leads to excessive tearing, which may cause discomfort, and may also result in repeated eye infections or inflammation of the tear ducts.
Dacryostenosis can sometimes resolve on its own without any medical intervention during the first year of life. However, in cases where the condition persists or causes recurrent eye infections, treatment options may be recommended. One common treatment approach is tear duct massage, where gentle pressure is applied to the tear duct area to help open up the narrowed channel. Additionally, in severe or persistent cases, surgical procedures may be necessary to remove the blockage and restore normal tear drainage.
Overall, dacryostenosis is a condition that involves the partial or complete obstruction of the lacrimal ducts in infants, resulting in excessive tearing and potential eye infections.

Etymology of DACRYOSTENOSIS
The word "dacryostenosis" can be broken down into two parts: "dacryo-" and "stenosis".
1. "Dacryo-" is derived from the Greek word "dákryon" (δάκρυον), meaning "tear". This root is also seen in other medical terms related to tears, such as "dacryocystitis" (inflammation of the tear sac) or "dacryoscopy" (examination of the tear ducts).
2. "Stenosis" is a term of Greek origin as well, derived from the word "sténos" (στενός), meaning "narrowness" or "constriction". This root is commonly used in medical terminology to describe a narrowing or blockage of a bodily passage, artery, or duct.
