Induced Myopia Secondary to Blunt Trauma

Area of Science:

• Ophthalmology
• Trauma Care

Background:

• Blunt head trauma can lead to ocular complications.
• Sudden visual loss necessitates prompt and accurate diagnosis.

Observation:

• A 28-year-old male experienced sudden, severe left eye vision loss after blunt trauma.
• Slit lamp examination revealed shallow anterior chamber depth (ACD) in the affected eye.

Findings:

• Anterior segment optical coherence tomography (AS-OCT) documented forward displacement of the iris-crystalline lens diaphragm.
• This was attributed to ciliary body anterior rotation and ciliochoroidal effusion.
• A significant temporary myopic shift of approximately 7.00 Diopters was observed, resolving within 15 days.

Implications:

• AS-OCT is a valuable tool for diagnosing and documenting traumatic anterior segment changes.
• Understanding these mechanisms aids in managing blunt eye trauma and associated refractive errors.
