—In their interesting article "Subretinal Neovascularization Following Metallic Intraocular Foreign Body Trauma," in the April 1986 Archives, Trimble and Schatz1 state that "subretinal neovascularization as a complication of chorioretinal injury from a metallic intraocular foreign body, to our knowledge, has not previously been reported."It may be of interest to them that I reported, in The Blood-Retinal Barriers,2 a case of a patient in whom subretinal neovascularization developed at the impact site after a direct hit on the paramacular retina by a copper wire. The wire struck the macula just superonasal to the fovea, after which it fell into the vitreous.I suggested that this appeared to be a model for the development of subretinal new vessels in humans. I agree that the metal wire makes a break in the retina, retinal pigment epithelium, Bruch's membrane, and, possibly, the choricapillaris, which triggers the formation of
