Bilateral neuroretinitis in a 6-year-old boy with acquired toxoplasmosis.

nopathy showed significant improvement in visual acuity and reduction of vascular leakage after focal laser had failed to improve the situation. The mechanism of this effect of intraocular steroid treatment is poorly understood, but it appears to restore a compromised inner bloodretina barrier. Our case illustrates that the beneficial effect of intravitreal triamcinolone on vasogenic macular edema may be independent of the initial insult. As this is only a case report with limited follow-up, more research is needed to establish if there is a beneficial longterm effect and if there are any unique safety concerns in cases of radiation-induced retinopathy, such as an increased susceptibility to the development or reactivation of intraocular malignancies. Repeated injections seem to be needed to maintain the initial effect. Furthermore, it remains unclear whether this treatment will alter the course of the ischemic and neovascular processes associated with radiationinduced retinopathy.
