In 2021, a request was received to inactivate this concept, citing the inaccuracy of including “glaucoma” in the term. The term “acute” should refer specifically to the acute closure of the angle. While this condition can lead to increased intraocular pressure, it is not appropriate to imply that glaucoma is present.
This change has been pending due to the expectation that approval from international glaucoma societies might be required. However, after further discussion with Ian and Anthony, there is consistent evidence that “acute angle closure” is consistently used as the correct terminology rather than “acute angle closure glaucoma.”  
The following societies use the term acute angle closure rather than acute angle closure glaucoma.

AAO (2013 by a glaucoma specialist)
AAO (2021 by a glaucoma specialist)
AAO Primary Angle-Closure Disease Preferred Practice Pattern (2021)
Glaucoma UK (patient support charity)


Additionally:
• The European Glaucoma Society Terminology and Guidelines for Glaucoma (2020) exclusively refers to acute angle closure, with no mention of acute angle closure glaucoma.
• The RCOphth Management of Angle Closure Glaucoma Guideline (2020) also exclusively refers to acute angle closure, without reference to acute angle closure glaucoma.
•The Asia-Pacific Glaucoma Guidelines (2016) similarly use acute angle closure without mentioning acute angle closure glaucoma.

Given the consistent terminology used across authoritative sources, there is strong justification for the inactivation of 30041005 | Acute angle-closure glaucoma (disorder). References to acute angle-closure glaucoma are predominantly found in non-specialist sources.

The intention is to inactivate this concept; however, we welcome any comments or concerns regarding this decision. The correct terminology already exists in SNOMED 1111451000000106 |Acute angle closure (disorder)|
