Risk factors for delayed suprachoroidal haemorrhage following glaucoma surgery

Abstract

Aim: To determine the incidence, risk factors and outcomes of delayed suprachoroidal haemorrhage (DSCH) after glaucoma surgery. Methods: A retrospective case-control study was performed at a tertiary referral eye hospital on patients who presented with DSCH following glaucoma surgery. Cases were compared with a matched-control population that underwent equivalent procedures but did not develop DSCH. The main outcome parameters were incidence of DSCH, risk factors associated with its occurrence, visual outcome and prognostic factors. Results: Of the 2752 glaucoma surgeries performed during the 10-year recruitment period, 29 cases of DSCH (1%) were identified. An increased incidence of DSCH wa..
