Précis: 240-degree and 360-degree goniotomy (GT) demonstrated similar efficacy in intraocular pressure (IOP) reduction, both outperforming 120-degree GT in patients with juvenile open angle glaucoma (JOAG) at postoperative 6-month follow-up. Objective: To compare the surgical efficacy and safety of 120-degree, 240-degree, and 360-degree GT for patients with JOAG. Patients and Methods: This multicenter retrospective study included 102 eyes of 102 patients with JOAG, who underwent GT with a follow-up of at least 6 months. Patients were categorized into 3 groups: (1) 120-degree GT, (2) 240-degree GT, and (3) 360-degree GT. IOP, glaucoma medications, and complications were recorded at baseline and the final visit. Complete success and qualified success were defined as a postoperative IOP ≤21 mm Hg without and with medications, respectively. Results: Mean age of the participants was 24.4 ± 7.9 years. After a mean follow-up of 8.1 ± 2.7 months, complete success rates were similar between the 240-degree GT (45.2%) and the 360-degree GT (63.2%; P = 0.135), and both were superior to 120-degree GT (18.2%; P < 0.05). Qualified success rates among patients in the 120-degree, 240-degree, and 360-degree GT groups were 93.9%, 96.8%, and 100%, respectively, and showed no statistically significant difference (P = 0.292). 360-degree GT required fewer medications than 240-degree GT and 120-degree GT (P < 0.05), with no significant difference in medications between 120-degree GT and 240-degree GT (P > 0.05). Hyphema was the most common postoperative complication, with a significantly higher incidence in the 360-degree GT (68.4%) compared with the 240-degree GT (41.9%) and 120-degree GT (33.3%; P < 0.05). Conclusions: 240-degree and 360-degree GT showed similar efficacy in IOP reduction and were superior to 120-degree GT. More extensive GT may provide better outcomes in JOAG.

4136 Introduction: BV prolongs overall survival (OS) and progression-free survival (PFS) when added to 1st- or 2nd -line chemotherapy (CT) in mCRC. Though serious toxicities specific to BV are uncommon, a retrospective pooled analysis of 5 randomized trials showed an association of arterial thromboembolic events (ATEs) with BV use (3.8% vs 1.7% with CT alone), with age ≥65 and prior history (Hx) of ATE identified as associated risk factors (Skillings, JCO 2005). The BRiTE mCRC registry evaluated BV-associated serious adverse events (SAEs), including ATEs presenting as SAEs (sATE), in a general practice setting. Methods: Pts and methods have been described (Hedrick ASCO 2006). Hx of sATE, timing of prior sATE relative to starting BV, and anti-platelet agent (anti-plt) use were summarized. Definition of sATE included myocardial infarction (MI), cerebral vascular accident (CVA), transient ischemic attack (TIA), and peripheral arterial disease. Incidence rate of sATE was expressed as events per pt-yr of follow-up. Fisher’s exact test and multiple logistic regression was used to assess the univariate and multivariate associations. Results: Median follow- up was 17.5 mo. Of 1953 evaluable pts, 45.9% (n=896) were ≥65, 18.0% (n=352) had Hx of sATE, and 11.2% (n=219) received anti-plt. A total of 38 sATE [CVA (n=14), MI (n=11), sudden cardiac death (n=1), TIA (n=7), and other (n=5)] were reported in 34 (1.7%) pts. Median time to sATE was 3.6 mo. The calculated sATE rate was 2.2/100 pt-yr overall and 4.7/100 pt-yr in pts with prior sATE. Table 1 summarizes the results of univariate and multivariate analyses. Conclusions: In this series of BV-treated pts, the incidence of sATE associated with BV use was comparable with the rate of analogous events reported in previous controlled trials of BV in mCRC. In this series, prior history of sATE and ECOG PS were found to be associated with sATE risk in multivariate analyses. [Table: see text] [Table: see text]
