title: Vitreous haemorrhage without obvious cause: national survey of management practices.
abstract: OBJECTIVE
  We undertook a national survey to establish the management of dense vitreous haemorrhage without obvious cause.
  
  
  METHODS
  Cross-sectional anonymous self-reporting survey of ophthalmic practitioners within three target groups: vitreoretinal specialists (VRS), nonvitreoretinal specialists (NVRS), and associate specialists (AS).
  
  
  METHODS
  Presentation of the hypothetical scenario of a patient presenting with recent onset (fresh) vitreous haemorrhage with no retinal view and no apparent cause on history taken at presentation.
  
  
  METHODS
  The relative importance assigned by respondents to eight examination techniques at presentation. The proportion of respondents stating that they would review patients and perform B-scan examination at or prior to 2 weeks after presentation. The stated time to surgical intervention by VRS, and the time to referral by NVRS and AS.
  
  
  RESULTS
  VRS ranked B-scan examination higher than AS (P<0.001). A total of 98.1% of VRS indicated that they would next review patients within 2 weeks of presentation, this figure fell to 86.5% for NVRS and 47% for AS (P<0.001). A 98.1% of VRS indicated that they would next perform B-scan ultrasound within 2 weeks of presentation, this figure fell to 88.9% for NVRS and 70.6% for AS (P<0.001). The mean time to surgical intervention by VRS was 9.5 weeks without retinal tear demonstrated on B-scan, 1.7 weeks with retinal tear demonstrated on B-scan and 1 week with retinal detachment demonstrated on B-scan. The mean time to referral by NVRS was 6.7 weeks and by AS was 11.9 weeks.
  
  
  CONCLUSIONS
  Vitreoretinal specialists considered B-scan the most important examination tool, and typically perform B-scan early and frequently after presentation. Non-VR ophthalmologists (particularly associate specialists) review patients and perform B-scan ultrasound later and less often than vitreoretinal specialists. We recommend early referral to VR specialists, as reported referral even in uncomplicated cases would often be outside the timeframe within which VR specialists would typically choose to operate.
