Case in brief
Two cases of postoperative tube obstruction in patients with Aurolab Aqueous Drainage Implants (AADI) were treated with Nd: YAG laser. The first case involved an 11-year-old girl with iris obstruction, successfully treated with laser iridotomy, resulting in stable intraocular pressure at 12 mmHg after 7 months. The second case, a 38-year-old man, experienced vitreous obstruction, where laser vitreolysis initially reduced intraocular pressure but later led to complications requiring implant explantation.
Diagnostic / clinical pearl
Nd: YAG laser can be an effective first-line treatment for tube obstructions in glaucoma drainage devices, particularly in high-risk patients, potentially avoiding the need for surgical revision.
Why it matters
This case highlights the utility of Nd: YAG laser in managing complications of glaucoma drainage devices, especially in resource-limited settings, while emphasizing the importance of monitoring for potential long-term complications.
