Trypan blue-assisted neodymium:YAG laser treatment for overfiltering bleb.
Overfiltering blebs can lead to postoperative problems including hypotony maculopathy, decreased vision, and increased ocular discomfort. Many methods have been used in the past with varying results. Various lasers have been used in an attempt to cause localized scarring and fibrosis. We report a treatment technique to noninvasively treat a patient with an overfiltering bleb using trypan blue and a frequency-doubled continuous-wave neodymium:YAG laser emitting green light.
