Nd:YAG laser trabeculopuncture (YLT) for glaucoma with traumatic angle recession.
Traumatic angle recession caused by blunt trauma often induces uncontrollable glaucoma despite the maximum medical therapy tolerated, such as argon laser trabeculoplasty (ALT), with no or little benefit. Therefore, instead of ALT, we tried Nd:YAG laser trabeculopuncture (YLT) on 11 patients with this type of glaucoma. The intraocular pressure of these patients was followed up for 15 +/- 7 months (average +/- SD). In 6 of 7 eyes treated initially with YLT, the IOP was significantly reduced, so medication was discontinued. Four other cases with uncontrollable IOP after failed ALT were treated with YLT. The IOP of 3 cases was successfully controlled by medication after YLT. These YLT results were then compared with those of ALT in 11 glaucoma patients with traumatic angle recession. Seven of 11 cases treated initially with ALT failed in less than 3 months, and surgical intervention or additional laser treatments were required. The probability of success from the time-series analysis at 12 months after each laser application was 0.909 in YLT, 0.273 in ALT. YLT offers significant advantages over ALT for the treatment of glaucoma with traumatic angle recession after blunt trauma and thus merits further study.
