Morphovascular changes after Anti-VEGF intravitreal injection for a choroidal neovascularization secondary to COVID-19 infection in a pediatric patient.

Choroidal neovascularization (CNV) is a common pathologic lesion that occurs in various chorioretinopathy. Although the incidence of CNV is quite rare in children and adolescents, these lesions have a severe impact on visual acuity and quality of life over patients' lifetime. The management of CNV in pediatric patients is challenging, clear guidelines are limited due to a lack of randomized clinical trials. However, the more promising option is the use of vascular endothelial growth factor (VEGF) inhibitors. We reported a case of recurrent idiopathic choroidal neovascularization in a healthy pediatric patient after COVID 19 infection. Optical coherence tomography angiofraphy (OCTA) showed, in a non invasive way, a choroidal neovascularization at the posterior pole including macula and superior temporal arcade in the right eye, while the left eye was unaffected. In order to inactivate the neovascularization, intravitreal injections of anti-VEGF (Lucentis-Ranibizumab 0.3 mL) were performed in the right eye. Six months after the injections BCVA of the right eye was improved from 0.7 logMAR to 0.2 logMAR. OCT-A examination did not detect any signs of attivation of the preexistent neovascularization. It is reasonable to assert that Anti-VEGF could be the main treatment in case of choroidal neovascularization in young patients after COVID 19 infection due to the high chorioretinal level of VEGF-A described in these diseases.
