Ibopamine challenge testing becomes negative following successful trabeculectomy surgery.

A glaucoma patient with a positive ibopamine challenge will show a negative challenge result when re-tested following trabeculectomy surgery.

Ibopamine challenge testing differentiates glaucoma suspect, stable glaucoma and progressive glaucoma cases.

GS patients may be differentiated from those with SG or PG by their IOP response, and SG may be differentiated from PG patients by their change in OCV following an ibopamine challenge.
