Insights
Orbital blowout fractures in children often present atypically, leading to delayed diagnosis. Swift surgical intervention is crucial to prevent vision impairment and permanent vision loss.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Trauma Surgery
Background:
- Orbital blowout fractures present uniquely in children, differing from adult presentations.
- Classic pediatric signs include white eye injury, upgaze diplopia, and malaise, often without subconjunctival hemorrhage.
- Oculovagal reflex can be triggered by globe pressure, a factor in ophthalmic and orbital trauma.
Purpose of the Study:
- To audit pediatric and young adult cases requiring surgical intervention for orbital blowout fractures.
- To highlight diagnostic and management challenges in pediatric orbital trauma.
Main Methods:
- Retrospective audit of patients referred to an Orbital Service.
- Inclusion of pediatric and young adult patients who underwent surgical repair.
Main Results:
- A significant proportion (one-third) of pediatric patients with orbital blowout fractures are admitted for head injury observation.
- The actual cause of symptoms in these children is frequently misdiagnosed or overlooked.
- Delayed recognition impacts the appropriate and timely management of orbital fractures.
Conclusions:
- Pediatric orbital blowout fractures necessitate prompt surgical intervention to prevent complications.
- Early surgical treatment is vital to avoid muscle ischemia and irreversible vision damage.
- Head injury observation protocols can delay necessary surgical treatment, potentially compromising outcomes.
Background:
The oculovagal reflex is well described in ophthalmic surgery, but may be caused by any manner of pressure on the globe. Children with orbital blowout fractures present in a different manner from adults. The classic presentation in children is a white eye injury (ie, no subconjunctival haemorrhage) with upgaze diplopia and general malaise.
Methods:
A retrospective audit is presented of paediatric and young adult patients referred to the Orbital Service at St George's Hospital who required surgical intervention.
Results:
One-third of children with orbital blowout fractures are admitted for head injury observations, while the true cause for the symptoms goes unrecognised and uninvestigated.
Conclusions:
Orbital blowout fractures in children require more swift intervention than in adults if muscle ischaemia and permanent impairment of the vision is to be avoided. The delay for head injury observation may therefore compromise the surgical outcome.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
