Trabecular Staining With the Blue Donut Technique in GATT for Juvenile Glaucoma

Drs. Serhat Imamoglu and Ali Olgun present a gonioscopy-assisted transluminal trabeculotomy (GATT) procedure using the Blue Donut technique for trabecular meshwork staining in a 30-year-old patient with juvenile open-angle glaucoma. The Blue Donut technique allows for trypan blue staining of the trabecular meshwork without inadvertent staining of the lens. Dispersive viscoelastic is deposited over the pupil, and then once the eye is pressurized diluted trypan blue is injected to form a blue donut shape. After 30 seconds, the trypan blue is washed out and more viscoelastic is injected into the anterior chamber.
