Hemorrhage From Iris Root Trauma During GATT

Show Description +

[No narration] A 74-year-old patient underwent cataract surgery combined with a 180-degree gonioscopy-assisted transluminal trabeculotomy (GATT) in the left eye. A microvitreoretinal blade was used to perform a goniotomy. A 5-0 polypropylene suture, with its tip cauterized, was held with micrograspers and introduced into the goniotomy site. During this process, the micrograspers inadvertently moved posteriorly and came in contact with the iris, resulting in traumatic bleeding from the iris root. To manage the hemorrhage, a cohesive OVD was injected inferiorly to displace the blood superiorly. Care was taken to prevent the blood from dispersing, which could have further obscured the view of the angle.
