Abnormal trabecular meshwork morphology

MedGen UID:: 868420
•Concept ID:: C4022814
•: Anatomical Abnormality

Synonym:	Abnormality of the trabecular meshwork

HPO:	HP:0012630

Definition

An anomaly of the trabecular meshwork, which is the porelike structure surrounding the entire circumference of the anterior chamber at the base of the cornea and near the ciliary body. The trabecular mesh work is responsible for draining the aqueous humor into the canal of Schlemm. [from HPO]
