To report a case of ophthalmomyiasis interna with optic nerve invasion that was treated with oral ivermectin and prednisone.
Case report with retrospective review of medical records and multimodal imaging studies.
A Christmas tree farmer in his sixties presented with expanding multicolored, spiraling photopsias in the left eye. The visual acuity measured 20/50, and examination and imaging findings showed subretinal tracks consistent with ophthalmomyiasis interna. After several weeks of spontaneous improvement, the visual acuity decreased to 20/150 and fundus examination showed new optic disc edema that was treated with ivermectin and prednisone. Despite the development of optic disc pallor, the visual acuity improved to 20/25.
Subretinal fly larvae can occasionally exit the eye by invading the optic nerve. Treatment of optic nerve involvement with ivermectin and prednisone can result in an excellent visual outcome.
报告一例眼内蝇蛆病伴视神经侵犯，经口服伊维菌素和泼尼松治疗。
病例报告并回顾性分析病历和多模态影像学研究。
一位 60 多岁的圣诞树种植者左眼出现扩张性多色、螺旋状幻视。视力为 20/50，检查和影像学发现符合眼内蝇蛆病的视网膜下轨迹。经过数周的自发改善，视力下降至 20/150，眼底检查显示新的视盘水肿，给予伊维菌素和泼尼松治疗。尽管视盘苍白发展，但视力仍提高至 20/25。
视网膜下的蝇幼虫偶尔可通过侵犯视神经而退出眼球。视神经受累采用伊维菌素和泼尼松治疗可获得良好的视力结果。
