Birmingham Eye Trauma Terminology (BETT)

The Birmingham Eye Trauma Terminology (BETT) is a standardized system created to ensure clear and consistent communication among healthcare professionals when describing mechanical injuries to the eye. Before BETT, terms like “perforating” or “penetrating” were used inconsistently across regions, leading to confusion in both clinical care and research. In 1996, Kuhn and colleagues introduced BETT to classify ocular trauma unambiguously based on whether the eye wall (cornea or sclera) was fully penetrated (open-globe) or remained intact (closed-globe) ResearchGateEyeWiki. By providing precise definitions for each injury type and subgroup, BETT has become the international standard for documenting eye trauma in emergency departments, operating rooms, and clinical studies.

Types of Ocular Trauma

BETT divides mechanical eye injuries into two main categories—Closed Globe Injuries and Open Globe Injuries—and further refines them into specific subtypes:

• Closed Globe Injuries
  Injuries in which the full thickness of the eyewall is not breached. Within this category, there are:

  • Contusion: A blunt injury causing damage without a full-thickness wound, often leading to internal bleeding or swelling behind an intact eyewall EyeWiki.

  • Lamellar Laceration: A partial-thickness cut in the cornea or sclera caused by a sharp object that does not extend through the entire eyewall EyeWiki.

• Open Globe Injuries
  Injuries characterized by at least one full-thickness wound of the eyewall. Subgroups include:

  • Rupture: A full-thickness injury resulting from blunt force that causes the eyewall to fail at its weakest point, such as near muscle insertions or previous surgical scars EyeWiki.

  • Laceration: A full-thickness cut by a sharp object. Lacerations are further classified as:

    • Penetrating Injury: A single entrance wound without an exit, caused by a sharp object entering the eye EyeWiki.

    • Perforating Injury: Two full-thickness wounds—an entrance and an exit—caused by the same object passing entirely through the eye EyeWiki.

    • Intraocular Foreign Body (IOFB): A retained fragment of the penetrating object that lodges within the eye, potentially causing ongoing inflammation and infection EyeWiki.

Causes of Eye Trauma

1. Direct Blunt Force
   Strikes from fists, balls, or other blunt instruments can compress the globe, leading to contusions or ruptures depending on force and location. Such impacts may also cause secondary injuries like hyphema (blood in the anterior chamber).

2. Penetrating Sharp Objects
   Objects such as knives, glass shards, or metal fragments can slice through the cornea or sclera, creating lacerations that risk infection and severe visual loss if not promptly repaired.

3. Intraocular Foreign Body Ingress
   High-velocity objects (e.g., nail-gun projectiles, shrapnel) can carry debris into the eye, embedding foreign material that triggers inflammation, scarring, and possible endophthalmitis.

4. Chemical Splash
   Alkaline or acidic chemicals can burn the ocular surface, damaging the corneal epithelium and underlying structures; although non-mechanical, severe chemical burns often accompany mechanical trauma and are addressed in modified BETT schemas www1.racgp.org.au.

5. Thermal Burns
   Exposure to hot liquids, steam, or flames can coagulate proteins in the cornea and conjunctiva, causing opacification and risk of symblepharon (adhesion between eyelid and eyeball).

6. Sports Injuries
   Fast-moving balls, rackets, or protective gear failures can result in both blunt and penetrating trauma, with baseball and racket sports being frequent culprits.

7. Workplace Accidents
   Industrial settings pose risks from machinery, welding sparks, or metallic debris, leading to IOFBs or lacerations that require surgical exploration and removal.

8. Falls
   Falls onto hard surfaces or objects like furniture can produce contusive forces or penetrate the eye if objects like glass tables are involved.

9. Motor Vehicle Collisions
   Dashboard, steering wheel impacts, or shattered glass can inflict blunt or penetrating ocular injury, often accompanied by facial fractures.

10. Projectile Weapons
    Firearms, BB guns, and airguns can cause devastating penetrating eye injuries with high exit velocities, necessitating emergent surgical intervention.

11. Explosive Blasts
    Blast waves from explosions generate rapid pressure changes, causing both closed-globe contusion injuries and penetrating shrapnel-related open-globe injuries Wikipedia.

12. Iatrogenic Injuries
    Surgical or medical interventions (e.g., misplaced needles during retrobulbar block) can inadvertently puncture the globe, leading to open-globe wounds.

13. Animal Bites or Claws
    Pet scratches or bites can lacerate the eyelid and eyewall, introducing both mechanical damage and zoonotic infection risk.

14. Assault
    Physical altercations often involve punches or thrown objects, causing blunt or penetrating trauma correlated with interpersonal violence statistics.

15. Occupational Exposures
    Agricultural work exposes the eye to tools like sickles or organic debris that can both injure mechanically and seed fungal infections in an open globe.

Symptoms of Eye Trauma

1. Eye Pain
   Sharp or aching pain often accompanies both closed and open globe injuries, signaling tissue damage and inflammation.

2. Blurred or Decreased Vision
   Disruption of corneal clarity, intraocular bleeding, or structural damage can immediately reduce visual acuity.

3. Photophobia
   Sensitivity to light arises from iris spasm or corneal injuries exposing nerve endings.

4. Redness (Hyperemia)
   Conjunctival blood vessels dilate or rupture, leading to redness that can be diffuse or localized.

5. Tearing (Epiphora)
   Reflexive tearing occurs in response to ocular surface irritation or pain.

6. Foreign Body Sensation
   Patients often feel as though something is lodged in the eye, especially with surface abrasions or retained IOFBs.

7. Subconjunctival Hemorrhage
   Blood collects under the conjunctiva in closed-globe contusions or minor ruptures, creating a striking red patch.

8. Hyphema
   Blood in the anterior chamber after blunt trauma can form a visible layer, risking raised intraocular pressure and corneal staining.

9. Floaters or Flashes
   Vitreous hemorrhage or tractional forces on the retina may present as moving spots or light flashes in the visual field.

10. Diplopia (Double Vision)
    Orbital fractures or extraocular muscle entrapment can misalign the eyes, causing double vision.

Diagnostic Tests for Eye Trauma

Physical Exam

1. Visual Acuity Test
   Measures clarity of vision using a Snellen chart or near card to establish baseline function and detect deficits.

2. Pupillary Reflex Assessment
   Evaluates direct and consensual light reflexes to identify afferent or efferent nerve pathway injuries.

3. Intraocular Pressure (IOP) Measurement
   Tonometry (non-contact or applanation) gauges pressure inside the eye; caution is required in open-globe injuries to avoid extrusion of intraocular contents.

4. Ocular Motility Examination
   Assesses eye movement in all directions to detect muscular or nerve entrapment, often caused by orbital fractures.

Manual Tests

5. Slit‐Lamp Examination
   Provides a magnified, illuminated view of anterior structures to identify corneal lacerations, anterior chamber depth changes, or iris prolapse.

6. Seidel Test
   Application of fluorescein dye and cobalt‐blue light to detect aqueous humor leakage through a corneal or scleral wound.

7. Gonioscopy
   Uses a special lens to inspect the anterior chamber angle, useful if angle recession is suspected after blunt trauma.
