Intraocular Nematode Affixed to Posterior Lens Capsule

Ophthalmic Surg Lasers Imaging Retina. 2015 Nov-Dec;46(10):1066-7. doi: 10.3928/23258160-20151027-16.


The clinical presentation of an intraocular nematode unusually affixed to the posterior lens capsule is described. A 64-year-old female patient presented with a 7-year history of gradually declining vision and enlarging central scotoma, but no inflammation. On follow-up 2 years later, vision had further declined and a non-motile, 8-mm nematode was seen affixed to the posterior lens capsule that remained unchanged through final follow-up. The patient disclosed having resided in Africa as a child. Systemic review revealed no evidence of extraocular involvement. Nematode carcasses may remain preserved in the human eye for extended periods without ongoing inflammation.
