RESUMO
Each year an estimated 1.3 million Americans suffer eye injuries. There is little information in the literature regarding the prevalence, demographic characteristics, and prognosis of these patients. The Eye Injury Registry of Alabama (EIRA) serves as the first and only statewide system of its kind for the collection of information on serious eye injuries. We have analyzed 736 cases of serious eye injury (injury involving permanent structural or functional change) accumulated by the EIRA between August 1982 and May 1986. Prognosis was found to be related to early diagnosis and initial vision. Individuals with follow-up vision of 20/40 or better were found in all early diagnostic groups, and 13% of patients with no light perception on initial examination had some improvement on follow-up. The worst visual prognosis was among those patients suffering blunt eyeball rupture, of whom 40% had no light perception and 25% regained vision of 20/100 or better.

We retrospectively studied 14 patients with bilateral ocular shotgun injury in order to determine overall visual prognosis and factors affecting individual prognosis. Although only eight of 28 eyes (29%) in this series recovered visual acuity of 20/100 or better, six of 14 patients (43%) recovered at least 20/100 and eight of 14 patients (57%) recovered visual acuity of at least 20/400. Tissue destruction in the form of severe ocular disorganization or direct injury of optic nerve or macula was the primary limiting factor to visual recovery in 16 of 20 eyes (80%) not recovering to 20/100, while retinal detachment was the limiting factor in only four of these 20 eyes (20%). While extensive ocular disorganization, direct optic nerve or macular injury, no light perception on initial examination, and multiple pellet injuries were predictive of poor outcome, retinal detachment and double perforating injury were not.

Two unrelated children with a similar syndrome were found to have mosaicism for a cell line containing one chromosome 12 with an additional faintly G-banding staining region that apparently represents a duplication of the distal portion of the long arm. The homology and the other chromosomes are normal, as are the parental chromosomes. The remarkable phenotypic similarity of the 2 patients and their resemblance to 2 previously reported patients with duplication of the same chromosome region suggests that duplication 12q24 results in a clinically identifiable malformation syndrome.
