Silent Sentinel: Incidental Discovery of Gunpowder-Induced Subconjunctival Foreign Bodies Three Years Post-firearm Injury.

Gunpowder-related ocular injuries are rare and can present significant diagnostic and management challenges. This case report describes a 27-year-old male who was discovered to have subconjunctival gunpowder foreign bodies during a routine annual medical examination. The patient presented with best-corrected visual acuity (BCVA) of 20/20 in both eyes and was asymptomatic, with no complaints of pain, visual disturbances, or other ocular symptoms. Biomicroscopic examination revealed three gunpowder spherules embedded in the inferotemporal bulbar conjunctiva of the right eye, the largest measuring approximately 1.5 × 0.5 × 0.5 mm. When questioned, the patient recalled a firearm injury from 3 years prior but had never experienced any ocular discomfort or required treatment. Bilateral fundus examination and ultrasound B-scan confirmed the absence of intraocular foreign bodies and an intact scleral wall. Given the patient's asymptomatic presentation, no immediate treatment was recommended. Instead, the patient was advised to return for follow-up if symptoms developed. The case underscores the importance of thorough examination and patient history in determining the appropriate course of action for ocular foreign bodies, especially those related to gunpowder. Despite their high-velocity impact, gunpowder-related foreign bodies are generally well tolerated, suggesting that observation can be a safe approach for asymptomatic cases. Nonetheless, a critical and patient-centered management strategy is essential, with interventions like phototherapeutic keratectomy (PTK) reserved for cases where foreign bodies cause visual impairment or other complications. This case report highlights the need for individualized treatment plans and suggests that observation can be a viable approach when dealing with asymptomatic ocular foreign bodies.
