A 95-year-old woman was referred to the ophthalmological department with ocular discomfort and conjunctival inflammation resistant to tobramycin-dexamethasone eye drops. An ocular examination revealed the presence of a subconjunctival moving mass in a flat trabeculectomy bleb (Figure). The excision of the mass was performed immediately, and a thin, whitish, cylindrical worm was entirely removed. Polymerase chain reaction amplification determined that the worm was Dirofilaria repens. The patient recovered and showed no long-term ocular damage.
