Prognostic factors in posterior open globe injuries (zone‐III injuries)

Abstract

From this study we determined the most important prognostic factor in zone III open globe injuries is the presenting acuity. Other prognostic factors associated with a poor final outcome are eyelid injury, iris deformity, lens damage, ocular hypotonia, coexisting injuries and low ocular trauma score (< or =2). Posterior open eye injuries were most commonly owing to metal entering the eyes of young men.

A new ocular trauma score in pediatric penetrating eye injuries

“…3,4 Despite public health campaigns designed to prevent eye injuries, open globe injuries still occur. Identifying the causes and the nature of these injuries in the population, and directing educational and legislative efforts towards minimizing eye injury, are the previous goals of prevention.…”

“…A higher OTS score is typically associated with a better prognosis. 4,9,19,26 In this study we used the POTS in pediatric penetrating eye injuries (Table 2); it is similar to the OTS, but not the same. We classified injuries using that score and assessed relationship of the final VA and the POTS.…”

“…Previous studies on ocular trauma have identified the risk factors associated with poor visual outcome, including initial VA, [20][21][22][23] size, and posterior extent of the wound (zone), 4,[20][21][22] the presence of an afferent pupillary defect, 20 type of injury, 20,21 presence of vitreous hemorrhage, 20,21 presence of lens damage, 20,21 presence of retinal detachment, 24 and the presence of an intraocular foreign body and endophtalmitis. 22,25 The OTS is a scoring system that includes VA at presentation and the extent of ocular trauma, as well as the presence or absence of globe rupture, endophthalmitis, retinal detachment, and relative afferent pupillary defect.…”

“…All open globe injuries are categorized by the open globe classification system into three anatomical zones. 4,10 Zone I includes the cornea and limbus, zone II is 5-mm posterior to the limbus, and zone III, which includes the macula and optic nerve, is posterior to zone II.…”

“…[1][2][3][4] Eye trauma constitutes 7% of all bodily injuries and 10-15% of all eye disease. 5,6 The severity of trauma is directly proportional to morbidity and affects the socioeconomic loss; however, this loss can be prevented if certain precautions are taken.…”
