Anterior Segment Optical Coherence Tomography-Assisted Surgical Planning for Removal of a Corneal Foreign Body: A Case Report and Literature Review.

Introduction: Corneal foreign bodies account for nearly one-third of all eye injuries and are a common emergency in ophthalmology. While many cases are straightforward, involving clear diagnosis and treatment, some present significant challenges due to the complexity of the foreign body involved.

Observation: A 20-year-old male presented with discomfort in his right eye following an accident while cutting a tree without wearing protective eyewear. Examination using slit-lamp biomicroscopy revealed a reed foreign body embedded in the cornea. Anterior Segment Optical Coherence Tomography (AS-OCT) provided detailed images, showing the foreign body embedded 300 µm beneath the corneal epithelium but not affecting deeper layers. The foreign body was surgically removed under topical anesthesia, followed by thorough cleansing and suturing of the wound.

Conclusion: AS-OCT is invaluable in the diagnosis and management of complex corneal foreign bodies, enabling precise treatment planning and successful outcomes, as demonstrated in this case.
