The following is a summary of the systematic review findings up to the date of our most recent literature search. If you have a specific clinical case, we strongly recommend you read all of the relevant references as cited and look for additional material published outside our search dates.

 

Retinal Imaging

  • The use of RetCam imaging to record retinal findings facilitates accurate quantification of the retinal features present and the opportunity for further opinions 1,2,3

  • There is a recorded instance of RetCam potentially contributing to retinal haemorrhage in the newborn 4; however, in a recent prospective study of 50 eyes in 25 children 60 minutes after a retcam examination for retinopathy of prematurity, none had developed retinal haemorrhage 5

  • MRI scan of the brain may include images of the eye. If this involves GRET2 sequences 6, or the use of susceptibility weighted imaging  7 it may reveal retinal haemorrhages
  • Hand-held spectral domain optical coherence tomography, with 8 or without 9 electroretinography may be of value in defining retinal features

Subconjunctival haemorrhages

  • These are thought to occur in infants with prolonged coughing or haematological disorders. Two studies report their presence in child abuse 10,11. There have been no large-scale studies of this association.

Examination and recording of retinal findings

  • Recent studies have evaluated tools to improve the standardized recording of retinal findings in suspected abusive head trauma 12,13,14
  • In a study of 72 children undergoing examination by ophthalmologists and non-ophthalmologists, non-ophthalmologists were correct in their findings in 44% of cases; they had no false-positives but retinal haemorrhages were present in the 13% of cases they missed 15. This highlights the importance of an appropriate examination technique.

Indications for ophthalmological examination in suspected abuse

  • An assessment of the value of retinal examination in children wth suspected abuse but no intracranial injury 16

Updated UK national guidance

This relates to the ophthalmological examination and assessment of children with suspected physical abuse, including a standardised examination pro forma based on our validated reporting tool 17,18

 

Pathophysiology of Retinal Haemorrhages

  • A finite element infant eye model indicates that shaking could generate sufficient force to cause retinal haemorrhage 19
