| Abstract |
To report the 3-month incidence rates of postoperative suprachoroidal hemorrhage after glaucoma filtration surgeries and to examine the subsequent surgical treatments in these eyes. This is a retrospective study using the nationally pooled, insurance claim-based MarketScan databases from the years 2007-2011. Patients with records of trabeculectomy and/or tube shunt procedures were identified, and all cases of "definite" (ie, properly coded) and "suspected" (possibly miscoded) postoperative suprachoroidal hemorrhage occurring within 3 months of their glaucoma filtration procedures were captured along with the surgical interventions used for this condition. Kaplan-Meier survival analysis was used to evaluate the 3-month incidence rates of suprachoroidal hemorrhage, and regression analysis was applied to calculate the odds ratios, confidence intervals, and P-values. There were 17,843 trabeculectomies and 9,597 tube shunt surgeries identified. Among these, there were 107 cases (247 including "suspected" cases) of postoperative suprachoroidal hemorrhage within 3 months of trabeculectomy and 113 cases (255 including "suspected" cases) within 3 months of tube shunt procedures. The 3-month cumulative incidence rate of postoperative suprachoroidal hemorrhage ranged from 0.6%±0.06% to 1.4%±0.09% after trabeculectomy and 1.2%±0.11% to 2.7%±0.16% after tube shunt surgery. Postoperative suprachoroidal hemorrhage was almost twice as likely to occur after tube shunt surgeries than after trabeculectomies for both "definite" and "definite" plus "suspected" cases (odds ratio, 1.98; 95% confidence interval, 1.51-2.58; P<0.001; and odds ratio, 1.95; 95% confidence interval, 1.63-2.32; P<0.001, respectively). Among the 502 "definite" and "suspected" cases of postoperative suprachoroidal hemorrhage, 32.9% (165 cases) had a treatment record of choroidal tap and 8.8% (44 cases) had a treatment record of pars plana vitrectomy. In this sample, the 3-month cumulative incidence rate of postoperative suprachoroidal hemorrhage was 0.6%-1.4% after trabeculectomy and 1.2%-2.7% after tube shunt procedures, and the majority of the cases appeared to be managed without further surgery. Postoperative suprachoroidal hemorrhage was almost twice as likely to occur after tube shunt surgeries as after trabeculectomies. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 April 2015.
All research outputs
#22,758,309
of 25,373,627 outputs
Outputs from Clinical Ophthalmology
#3,207
of 3,712 outputs
Outputs of similar age
#240,603
of 279,164 outputs
Outputs of similar age from Clinical Ophthalmology
#32
of 34 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,712 research outputs from this source. They receive a mean Attention Score of 4.9. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 279,164 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 34 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
