Previous vitrectomy and older age increase the risk of appositional suprachoroidal hemorrhage (ASCH). Patients with ASCH face poor visual outcomes, especially with delayed treatment.

Area of Science:

  • Ophthalmology
  • Surgical Complications
  • Retinal Diseases

Background:

  • Appositional suprachoroidal hemorrhage (ASCH) is a rare but serious complication during eye surgery.
  • Identifying risk factors and prognostic indicators is crucial for patient management and outcomes.

Purpose of the Study:

  • To determine the risk factors, prognostic factors, and clinical outcomes associated with perioperative appositional suprachoroidal hemorrhage (ASCH).

Main Methods:

  • A case-control study was conducted at a tertiary referral center.
  • Patients with perioperative ASCH (n=37) were identified via B-scan ultrasound and matched with controls (n=92).
  • Risk factors and visual acuity outcomes were analyzed.

Main Results:

Related Experiment Videos

  • Glaucoma surgery was associated with 71% of ASCH cases.
  • Previous vitrectomy (OR=12) and older age (OR=1.57/decade) were significant risk factors; hypertension was protective (OR=0.33).
  • Poor visual outcomes were linked to ASCH lasting >30 days, uveitis, dry age-related macular degeneration, and extracapsular cataract extraction. Median visual acuity decreased from 20/100 to 20/1600.

Conclusions:

  • Previous vitrectomy and advanced age are key risk factors for developing ASCH.
  • Patients with these risk factors should be counseled on the potential for poor visual and anatomic outcomes following ASCH.
