The BElfast Retinal Tear and detachment Score (BERT Score) in vitreous haemorrhage
1Liverpool University Hospital, Liverpool, UK. mwbaba@hotmail.com.
Objective:
To establish if the BElfast Retinal Tear and detachment Score (BERT Score) can be used in triaging patients presenting with vitreous haemorrhage to allow safe differentiation between those with retinal tears and detachments, versus haemorrhagic posterior vitreous detachments.
Methods:
Retrospective audit of 122 patients presenting to eye casualty with vitreous haemorrhage excluding trauma and vascular causes. Twenty-two patients were excluded from the study as they had no follow-up. The BERT Score was applied to the remaining 100 patients.
Results:
Vitreous haemorrhages with a BERT score ≥4 points were more likely to have a retinal tear or detachment (P = 0.0056). The sensitivity was 84.6% (confidence interval (CI) 65.0-100.0%), specificity 34.5% (CI 24.5-44.5%), positive predictive value 16.2% (CI 7.4-24.9%) and negative predictive value 94% (CI 85.4-100.0%).
Conclusions:
The BERT is a reliable scoring system to risk stratify patients with vitreous haemorrhage. Its high sensitivity and negative predictive value can help clinicians to detect high-risk patients.
