Spontaneous suprachoroidal haemorrhage: clinical features, visual outcomes and prognosis factors.

ABSTRACT

BACKGROUND: To describe clinical features, risk factors and outcomes of patients with diagnosis of rare spontaneous suprachoroidal haemorrhage (SSCH) over a 20-year period from a tertiary eye unit. METHODS: Retrospective, observational case-series of patients with SSCH, defined as SCH without a known cause at diagnosis. Variables analysed included age, gender, ethnicity, systemic and ocular comorbidities, systemic medication, initial and final best corrected visual acuity (BCVA), clinical features, management and follow-up. RESULTS: Total of 11 eyes of 11 patients were identified. Median age was 70 years (SD 25.9). Most patients were female (82%) and white British. Median follow-up period was 2.2 years. Hypertension was the most frequently associated underlying systemic disease (45%) and 36% were on anti-coagulant or anti-platelet therapy. High myopia was observed in 36% of cases. Presenting BCVA of 1.00 logMAR or better was a positive predictor of final BCVA. No significant improvement in the initial versus final BCVA was found in patients who underwent surgery versus those who remained under observation. CONCLUSION: Patients over 60 years-old with hypertension, anticoagulant treatment, high myopia, and pseudophakia were common. Visual outcomes were poor, surgical intervention had limited impact. Good initial BCVA predicted better final acuity while extensive SSCH correlated with poorer visual results. Despite the study's limitations, this series offers valuable insights into visual prognosis and prognostic factors.
