Ocular motility disturbances following trauma

Area of Science:

• Ophthalmology
• Neuroscience
• Trauma Surgery

Background:

• Trauma can lead to ocular motility disturbances, including diplopia and impaired eye rotations.
• These motility imbalances may result from direct eye injury, extraocular muscle damage, orbital wall fractures, or closed head trauma.
• Clinical presentations can evolve significantly from the acute post-injury phase to later stages.

Purpose of the Study:

• To outline the diagnostic methods for evaluating ocular motility disturbances post-trauma.
• To describe the therapeutic strategies for managing these motility impairments.
• To emphasize the importance of considering concurrent ocular injuries.

Main Methods:

• Diagnostic evaluation includes forced ductions, saccadic velocity recording, and active force generation.
• Ocular deviations are measured in cardinal positions of gaze.
• Imaging techniques such as computed tomography (CT) scans and ultrasonography are utilized.
• Assessment involves identifying slipped or lost muscles, restricted rotations, and paretic muscles.

Main Results:

• Early and late clinical findings in motility disturbances can differ substantially.
• Accurate diagnosis requires a comprehensive approach combining clinical examination and advanced imaging.
• Identification of specific muscle issues (slipped, lost, restricted, paretic) is crucial for treatment planning.

Conclusions:

• Effective management of post-traumatic ocular motility disturbances necessitates precise diagnosis.
• Treatment involves surgical interventions like lysis of adhesions, muscle lengthening/recession, and muscle strengthening (resection/advancement).
• In severe trauma cases, a thorough ocular examination is essential to rule out concomitant eye injuries alongside motility deficits.
