Perforation of the choroid and retina during strabismus surgery is considered the etiology in two cases of retinal detachment, a case of vitreal hemorrhage, and an endophthalmitis. The growth of connective tissue into the vitreous from the site of perforation may be an important factor in the prognosis of a detached retina resulting from this complication. Among 65 children who had undergone corrective surgery for strabismus, six (9.2%) had funduscopic lesions indicating perforation of the globe with a needle. The proper choice of needles, and great care in passing them through thin sclera is stressed.
