“…The disruption of arterial blood flow induces the stagnancy of capillary blood flow followed by venous stasis and thrombi, leading to a combined vascular occlusion. 8 A very likely explanation to this patient's subacute visual loss is the mechanism of ischemia-reperfusion. During transient circulatory disorders, there is a period of absent blood flow with immediate restoration.…”

Purpose: We present a case of an ischemic retinopathy with severe vision loss secondary to a childhood stroke.Methods: Case report.Results: An otherwise healthy 9-year-old girl presented with a 1-day history of impaired gait and speech. After performing computed tomography and magnetic resonance imaging, thrombosis of the left internal carotid artery was observed and a diagnosis of ischemic stroke was established. Serological autoimmune, coagulation, and viral panels were unrewarding. Cardiac, inflammatory, and coagulation disorders were ruled out. The cause was attributed to a focal cerebral arteriopathy, a common cause of childhood stroke. The patient was treated with mechanical thrombectomy followed by anticoagulation. The day after, the patient referred vision loss of 20/100 in the left eye. Fundus evaluation of the left eye depicted diffuse intraretinal hemorrhages and cotton-wool spots and there was retinal whitening at the posterior pole. Six weeks after, VA dropped to counting fingers.Conclusion: A macular optical coherence tomography revealed diffuse atrophic changes in the inner retinal layers at the macula, and the angio-optical coherence tomography showed an enlarged foveal avascular zone. We propose ischemiareperfusion as the primary explanation of this unusual event.

Traumatic submacular hemorrhage: available treatment options and synthesis of the literature

et al. 2019

Sub-macular hemorrhage (SMH) is a hematic collection between the neurosensory retina and the retinal pigment epithelium; one of its causes is ocular blunt trauma, that usually affects young patients. Persisting SMH leads to a damage of photoreceptors mediated by three main mechanisms: iron-related toxicity, impairment of diffusion of oxygen and nutriment, mechanical damage due to clot contraction. Since early photoreceptors’ damage has been reported within 24 h, it is suggested to provide an early treatment, although there are no guidelines or consensus between authors regarding treatment strategies. The aim of this review was to present and compare available treatment options, like intravitreal tissue plasminogen activator (tPA) associated with pneumatic displacement, pneumatic displacement alone, subretinal tPA injection with pneumatic displacement, and intravitreal anti-vascular endothelial growth factor (VEGF) injection. All procedures obtained consistent results, though the most effective seemed to be pars plana vitrectomy, subretinal tPA and gas tamponade, probably due to a quicker liquefaction and displacement of the clot. Limitations concern the greater invasiveness and the higher incidence of complications. Alternatively, intravitreal injection of tPA and gas may represent a less invasive option with fewer complications. Intravitreal injection of gas and prone position could be preferred in young patients without coexisting ocular pathology, being a minimally invasive treatment, with lower risk of complications and a good visual recovery. Anti-VEGF agent have found, to date, limited employment in cases of traumatic SMH even though they may be useful as alternative or adjuvant therapy. Most of the published literature consists of small studies and case reports, therefore further investigations and larger clinical trials are required to fully understand safety and efficacy of the procedures. A preoperative comprehensive evaluation may be helpful to realize a surgical plan tailored on patient.
