Summary
Delayed suprachoroidal hemorrhage (DSCH) is more common after tube shunt surgery than trabeculectomy. Patients with risk factors face poor visual outcomes following DSCH after glaucoma surgery.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Surgical Complications
Background:
- Delayed suprachoroidal hemorrhage (DSCH) is a rare but serious complication following glaucoma filtration surgery.
- Understanding its incidence, risk factors, and outcomes is crucial for patient management.
Purpose of the Study:
- To determine the incidence of DSCH after glaucoma filtration surgery.
- To identify risk factors associated with DSCH development.
- To evaluate the visual outcomes and prognostic factors for patients experiencing DSCH.
Main Methods:
- Retrospective case-control study.
- Analysis of 2285 glaucoma filtration procedures performed between 1986 and 2000.
- Comparison of 66 patients with DSCH to a control group without hemorrhage.
Main Results:
- DSCH incidence was 2.9% overall, with higher rates after tube shunt implantation (7.1%) compared to trabeculectomy (1.5-2.4%).
- Significant risk factors included white race, anticoagulation, postoperative hypotony, and aphakia/anterior chamber intraocular lens.
- Patients with DSCH experienced significantly poorer visual outcomes compared to controls.
Conclusions:
- Tube shunt implantation is associated with a higher incidence of DSCH than trabeculectomy.
- Caution is advised for patients with identified risk factors due to poor visual prognosis after DSCH.
