Delayed suprachoroidal hemorrhage after glaucoma filtration procedures1 ☆,
Section snippets
Materials and methods
The charts of all patients who underwent glaucoma filtration procedures by one glaucoma surgeon (LBC) who were diagnosed with postoperative suprachoroidal hemorrhage between 1986 and 2000 were reviewed. Patients were identified by searching through a database of patient records in the Glaucoma Department at Indiana University. Only those patients with confirmation of their diagnosis by echography or by ophthalmoscopic visualization of the hemorrhage were included in the study. Patients who had
Results
Of 2285 glaucoma filtration procedures, 66 (2.9%) DSCHs were identified. With regard to the type of filtration procedure, DSCH developed in 9 of 615 (1.5%) cases of trabeculectomy without antimetabolite, 30 of 1248 (2.4%) cases of trabeculectomy with antimetabolite, 2 of 72 (2.8%) valved tube shunt implantations, and 25 of 350 (7.1%) nonvalved tube shunt implantations (Table 1). The increased incidence of DSCH after tube shunts compared with trabeculectomy-associated DSCH was statistically
Discussion
The literature describing DSCH after glaucoma filtration surgery is limited. There is a scarcity of large single-surgeon case series comparing the incidence of DSCH after various types of glaucoma filtration procedures. The largest study to our knowledge involves a consecutive series of 500 glaucoma operations in which DSCH developed in 10 eyes (2%).6 In another prior study of 432 consecutive cases of trabeculectomy or tube shunt, DSCH developed in 13 cases (3.0%),7 similar to the incidence

2020, Journal of AAPOSCitation Excerpt :In a retrospective literature search of case series, Khan and colleagues3 found an incidence of 0.36%. Regarding the incidence of SCH following specific procedures, the incidence of SCH in adult eyes undergoing trabeculectomy is 2.0%-2.4%,1,2 compared with 3.31% (95% CI, 1.01%-8.47%) in our study. Paysse and colleagues16 reported an incidence of 6.1% after nonvalved drainage devices, whereas Ayyala and colleagues17 reported SCH in 4.7% of cases after valved drainage devices.
