A Retained Intraocular Surgical Needle 2 Years After Cataract Extraction

Arch Ophthalmol. 1999;117(5):691. doi:

Cystoid macular edema (CME) occurs not infrequently after cataract extraction.1 Various theories exist as to the cause of this phenomenon, including vitreous traction on the macula and uveal inflammation causing a disruption of the blood-retina barrier. Persistent irritation to the iris and anterior uvea may serve to promote or exacerbate this condition, and in part may help explain the observation that CME occurs more frequently in patients with anterior chamber intraocular lenses (IOLs) as compared with patients with posterior chamber IOLs.1,2 In this report we describe a patient with a retained intraocular suture needle after cataract extraction, in association with chronic CME unresponsive to medical therapy.
