Partial Lateral Rectus Avulsion Due to Cat Scratch

Area of Science:

• Ophthalmology
• Trauma Surgery

Background:

• Isolated rectus muscle rupture without globe damage is a rare clinical presentation.
• The medial rectus is most commonly affected, while the lateral rectus is least affected by trauma.
• Oblique muscles are less susceptible to traumatic injury due to protective bony structures.

Observation:

• A 37-year-old male presented with partial lateral rectus avulsion.
• The injury was a result of a cat scratch.
• Initial assessment focused on globe integrity and detailed eye examination.

Findings:

• Confirmed partial lateral rectus avulsion as the cause of eye movement abnormality.
• Determined the extent of muscle damage to guide treatment decisions.

Implications:

• Prompt diagnosis and management are crucial for optimal outcomes in rectus muscle injuries.
• Rabies and tetanus prophylaxis are essential considerations in animal-related eye injuries.
• This case underscores the importance of considering less common etiologies for extraocular muscle trauma.
