Central Retinal Vein Occlusion Secondary to an Intraocular Nematode

Arch Ophthalmol. 2005;123(5):704. doi:10.1001/archopht.123.5.704

A 20-year-old man was initially seen with painless visual loss in the right eye. Visual acuity was 20/200 OD. Fundus examination revealed a central retinal vein occlusion with moderate optic disc edema (Figure 1).

Across 2 months, progressive visual loss occurred to counting fingers at 5 feet OD. Examination now revealed massive optic disc edema and an exudative macular detachment. A motile, 1.5-mm long nematode was visualized exiting the optic disc (Figure 2).
