Corneal Edema as a Complication of a Loose Retinal Tack

Arch Ophthalmol. 1987;105(10):1326. doi:10.1001/archopht.1987.01060100028013

To the Editor.  —Retinal tacks represent a new technique of retinal fixation that is useful in complicated retinal detachments such as large tears and retinotomies.1-4 Tacks are made of plastic, nonmagnetic metallic alloy, or titanium. Little is known about side effects of tacks retained in human eyes.5 Intraoperative complications of tack insertion include retinal tears, choroidal and retinal hemorrhages at the site of penetration, and slippage of the tack.3 Tacks may dislodge up to nine months after insertion: three of 53 tacks became loose in one series.4 Postoperative complications from the intrusion of retinal tacks have included atrophy of the retinal pigment epithelium; retinal phlebitis; vitreous hemorrhage; focal corneal, iris, and retinal injuries; and mild corneal edema.5 We report a case of a free-floating tack complicated by severe corneal edema. The edema resolved after removal of the loose tack.
