Pupil peaking/suture track bleed as a sign of suture extrusion into the anterior chamber in suture GATT

Suture GATT is a cost-effective option to treat glaucoma; however, there are limited means to track progress of the suture. We describe pupil peaking/suture track bleed during surgery as a sign of suture extrusion into the anterior chamber. This sign was noted when the surgeon removed the surgical goniolens. The suture was then retrieved through a goniotomy. It is important to withdraw the suture before attempting retrieval to avoid damage to the iris. Recognizing this sign in time can prevent damage to anterior segment structures.
