Author | Study type | Description |
Binenbaum1 | Paediatric head trauma | IRHs resolved to none or ‘mild’ within 1–2 weeks. The maximum time to resolution in an isolated IRH was 32 days. PRHs persisted 5–111 days. IRHs TNTC did not persist greater than a few days, indicating that TNTC IRHs point to recent trauma, whereas PRHs with no IRHs suggests days to weeks since trauma. |
Hughes5 | Birth retinal haemorrhages | In 53 neonates, all RHs were intraretinal, and in 51 infants, all RHs resolved in 16 days (outliers present at 31–58 days from vacuum extraction). |
Pierre-Kahn6 | Suspected AHT | About 88.2% RHs disappeared within 16–30 days, of which 82% resolved within 2 weeks. A total of 8 eyes were normal before day 15, and 10 eyes still had IOH after 1 month. |
Emerson7 | Birth retinal haemorrhages | About 85% resolved within 2 weeks (1 subretinal haemorrhage resolved by 42 days). |
Schoenfeld8 | Birth retinal haemorrhages | A total of 9/10 eyes resolved in 23 days (1 up to 42 days). |
AHT, abusive head trauma; IOH, intraocular haemorrhage; IRHs, intraretinal haemorrhages;PRHs, preretinal haemorrhages;RHs, retinal haemorrhages; TNTC, too numerous to count.
