Factors associated with the poor final visual outcome after traumatic hyphema.
In order to determine the factors related to the worse final visual outcome following nonperforating traumatic hyphema, the clinical characteristics of 18 patients with visual outcome of 0.1 or worse were compared with those of 166 patients with visual outcome of 0.15 or better. The presence of posterior segment injuries such as macula edema, retinal hemorrhage, epiretinal membrane, and choroidal rupture were significant factors of a poor final visual outcome (P < 0.01). The presence of anterior segment injuries such as corneal blood staining, traumatic mydriasis, iridodialysis, cataract, and lens subluxation had significant predictive factors on a poor final visual outcome and the concurrent posterior segment injuries were more frequent in these patients. Initial visual acuity of 0.1 or worse, glaucoma, vitreous hemorrhage, and eyelid laceration were also significant associations of a poor final visual outcome (P < 0.05). Patients with initially larger hyphema (grade I or more vs microscopic) and older age group (16 years or more vs 15 years or less) tended to have poor final visual acuities. Rebleeding was not associated with significant deterioration in visual prognosis. We conclude that the posterior segment injuries seem to be directly related to a poor visual outcome rather than the occurrence of secondary hemorrhage.
