Glaucoma drainage devices (GDDs) are rapidly evolving.
There
are many types of implants being used or in the pipeline for the management of
intraocular pressure (IOP).
However,
a look into the history of GDDs shows how the process was started by using
horse hair for drainage of hypopyon (pus) initially, and later for aqueous
drainage in cases of absolute glaucoma.
