Expert Overview: Orbital (Eye Socket) Fractures – Medicolegal Considerations

Prepared by: Prof. Simon Holmes FDS RCS FRCS

Consultant Oral & Maxillofacial Surgeon

Specialist in Orbital Trauma and Reconstruction

introduction

The orbit is a complex anatomical structure comprising thin bones that house and protect the eye, its muscles, nerves, and associated soft tissues. Damage to this structure — whether from assault, road traffic collision, workplace accident, or sporting injury — has the potential to cause permanent functional and aesthetic harm.

In my capacity as a Consultant Oral and Maxillofacial Surgeon with over two decades’ experience at the Royal London Hospital, one of Europe’s largest major trauma centres, I have managed thousands of orbital fracture cases, including acute, complex, and revision scenarios. My work includes published research on orbital biomechanics, surgical techniques, and multidisciplinary management strategies. This depth of exposure underpins my medicolegal opinion in cases where causation, breach of duty, prognosis, and quantum require detailed analysis.

nature of orbital injuries

Mechanisms

Orbital fractures typically occur via two main mechanisms:

  • Hydraulic theory: A direct blow to the globe increases intraorbital pressure, fracturing the orbital floor or medial wall.
  • Buckling theory: Force applied to the orbital rim transmits through bone, causing the thin internal walls to fail.

Classification

In practice, orbital fractures are described as:

The distinction has medicolegal relevance: pure fractures often result from lower-energy but precise impacts (e.g., punches), while impure fractures are common in high-energy injuries such as road traffic collisions.

clinical consequences

From a legal perspective, it is essential to understand how orbital injuries can affect quality of life:

  • Diplopia (double vision): May be transient or permanent. Caused by muscle entrapment, scarring, or nerve injury. Persistent diplopia can prevent safe driving or working in certain roles.
  • Enophthalmos: Sunken appearance of the eye due to loss of orbital volume. Can be cosmetically disfiguring and psychologically distressing.
  • Hypoglobus: Downward displacement of the globe, affecting both function and appearance.
  • Nerve injury: Infraorbital nerve damage leads to numbness in the cheek, lip, and side of the nose; occasionally permanent.
  • Vision loss: Rare but catastrophic, occurring with optic nerve injury or vascular compromise.

standards of care

In the UK, the expected standard in managing orbital fractures is informed by NICE guidelines, Royal College recommendations, and accepted maxillofacial/ophthalmic practice. Key principles include:

  • Prompt assessment by a specialist team when orbital fracture is suspected.
  • Appropriate imaging (thin-slice CT with multiplanar reconstruction).
  • Orthoptic evaluation to assess ocular motility and detect muscle entrapment.
  • Urgent surgery in cases of paediatric 'white-eye' blowout fractures with muscle entrapment or acute vision risk (typically within 24–48 hours).
  • Early but not emergency surgery (generally within two weeks) for fractures causing functional deficits or significant risk of cosmetic deformity.
  • Precise surgical reconstruction restoring orbital volume and contour, ideally via concealed incisions and using appropriate implant material.

Failure in any of these areas may be relevant in establishing breach of duty.

common medicolegal issues

Delayed or Missed Diagnosis

If swelling masks deformity, a fracture may not be diagnosed at first presentation. A medicolegal opinion will consider whether a reasonably competent clinician should have ordered imaging or referred for specialist review based on the mechanism of injury and presenting symptoms.

Suboptimal Surgery

Poorly positioned implants, inadequate release of entrapped tissue, or under-correction of orbital volume can lead to persistent symptoms. In my expert witness work, I often review postoperative imaging to assess implant position against established anatomical landmarks and pre-injury symmetry.

Failure to Refer to MDT

Complex orbital injuries benefit from input by ophthalmology, oculoplastics, and orthoptics. Failure to involve appropriate subspecialists may be criticised if it leads to avoidable harm.

Causation Analysis

Not every poor outcome results from negligence. Some injuries have an inherently poor prognosis due to the severity of initial trauma, associated globe injury, or patient-specific factors. My role is to separate these from harm caused by substandard care.

Examination and Assessment in the Medicolgal COntext

A comprehensive medicolegal assessment includes:

  • History: Mechanism of injury, timeline of symptoms, prior treatment.
  • Visual Function: Assessment of acuity, diplopia patterns, visual fields.
  • Ocular Motility: Measured in all gaze positions; correlation with orthoptic records.
  • Globe Position: Hertel exophthalmometry for proptosis/enophthalmos.
  • Sensation: Infraorbital nerve testing.
  • Scarring: Documentation of surgical approach and residual marks.
  • Imaging Review: Pre- and postoperative CT scans with 3D reconstruction.
  • 8. Photographic Evidence: Standardised facial photography for asymmetry analysis.

Prognosis and quantum

In litigation, prognosis influences damages. My expert reports quantify:

  • Recovery trajectory: Most motility disturbances improve within 3–6 months; persistent beyond this are often permanent.
  • Surgical revision needs: Whether a patient would benefit from reoperation.
  • Cosmetic outcome: Degree of asymmetry or eyelid malposition.
  • Functional impact: On driving, reading, work duties, sports.
  • Psychological sequelae: Confidence loss, avoidance of social interaction.

Costing of future treatment may include secondary orbital surgery, eyelid revision, strabismus surgery, or camouflage procedures.

my approach as an expert witness

I hold Bond Solon Expert Witness accreditation and have provided evidence in civil personal injury, clinical negligence, and criminal assault cases. My reports are CPR Part 35 compliant and address:

  • Breach of duty
  • Causation
  • Prognosis
  • Quantum

I present my opinions clearly for a non-medical audience, avoiding unnecessary jargon, but I am prepared to defend them robustly in court with reference to peer-reviewed literature and accepted practice.

multidisciplinary exprtise

One of the most compelling aspects of my work for complex or disputed cases is my access to — and leadership within — a seamless MDT comprising:

  • Ophthalmologists
  • Oculoplastic surgeons
  • Orthoptists
  • Neuroradiologists

This structure mirrors the gold standard for managing orbital trauma and enables me to assess, with authority, whether a claimant’s care met that benchmark.

Summary

From a legal perspective, orbital fractures occupy a complex intersection between functional ophthalmic injury and facial disfigurement. The best outcomes rely on timely diagnosis, multidisciplinary assessment, and meticulous surgical reconstruction.

In my expert witness role, I:

  • Analyse whether accepted standards were met.
  • Distinguish unavoidable sequelae from negligent harm.
  • Provide clear, evidence-based prognosis and treatment costings.
  • Draw on unmatched UK experience and international publication record in orbital trauma.

With thousands of cases managed in a world-leading centre, I offer solicitors and the courts an authoritative, balanced, and clinically precise view — grounded in current best practice and extensive hands-on expertise.
