[Retinal neovascularization in a traumatic microhyphema].

CLINICAL CASE: This is a case of retinal ischaemia with subsequent neovascularization, in a 13 year-old boy who sustained a traumatic hyphema after blunt trauma.

DISCUSSION: Hyphemas can occur after blunt trauma, intraocular surgery, spontaneously and in association with the use of substances that alter platelet or thrombin function (aspirin, ethanol). Associated injuries are traumatic anterior uveitis, iridodialysis, optic atrophy, secondary hemorrhage and a traumatic cataract. This case illustrates the formation of retinal neovascularization in association with a microhyphema and the need for careful and prolonged ophthalmological examination in this clinical context.
