An Atypical Presentation of Sympathetic Ophthalmia in an Intact Globe Following Mechanical Fall: A Case Report and Literature Review

Purpose: To describe an atypical case of sympathetic ophthalmia presenting after blunt trauma causing disinsertion of the iris in an intact globe. Methods: Case report. Results: A 71-year-old lady presented to the Emergency Department following a mechanical fall. On examination, she was noted to have periocular haematoma, subconjunctival haemorrhage, hyphaema, and vitreous haemorrhage in the left eye, but there was no evidence of globe rupture. The presenting visual acuity was 6/18. As the hyphaema and vitreous haemorrhage settled, a complete loss of the iris was noted with normal fundus. She was re-admitted a month later under the medical team with urinary tract infection and reduced vision in both eyes. On examination, there was mild conjunctival injection, keratic precipitates, anterior chamber flare, 180-degree posterior synechiae, and vitritis with no fundal view of the right eye. She was diagnosed with sympathetic ophthalmia and was treated with topical and systemic corticosteroid. Her vision improved gradually with treatment and was stable at 6/6 on the right (sympathising) eye and 6/9 on the left (excited) eye at final follow-up. Conclusion: Sympathetic ophthalmia may result from non-penetrating ocular trauma. Comprehensive history of mechanism of injury and ophthalmic examination is essential so that prompt treatment can be given to improve the visual prognosis of affected patients.
