  • Radiation Retinopathy

    The iris was round and dilated well, with no transillumination defects or posterior synechiae. There was no iris or angle neovascularization on gonioscopy.[retina.com.au] Two weeks after treatment, the visual acuity was improved to 0.6 and the retinal thickness was decreased.[ncbi.nlm.nih.gov] […] tumors and close proximity to the macula and optic disc. 47 Chemotherapy, whether or not concurrent/concomitant with the radiation therapy, also increases the risk, 13, 48[clinicalgate.com]
