This study is proposed to review and analyze photobiomodulation as a strategy that has the potential to be a new hope therapy and non-invasive treatment for retinitis pigmentosa in the long term. PubMed® and Google Scholar were used […]

ABSTRACT The characteristic optical coherence tomography finding in solar maculopathy is a well-defined outer retinal hyporeflective space primarily involving the photoreceptor inner and outer segment layers. This typical optical coherence tomography image may be present in a few other pathologies, which currently constitute their main differential diagnoses. Our study shows the report of 12 eyes of 6 patients treated at the Hospital de Olhos do Paraná, presenting their clinical history and diagnostic images, with the purpose of comparing the findings […]
