The disease affects healthy young adults and commonly has a benign course, however, if complications such as macular edema or ischemia appears, treatment should be instituted immediately to avoid poor prognosis. A 40-year old white male patient consulted for a slight decrease in the sensitivity of the visual field in his left eye (OS). Visual acuities (VA) were 20/20 in both eyes. OS fundus examination showed dilated and tortuous retinal vessels, disc edema, and retinal hemorrhages. The patient was diagnosed with papillophlebitis. OS VA decreased to 20/200 due to macular edema, and he was treated with a intravitreal dexamethasone implant. An exhaustive and interdisciplinary exploration process was performed, identifying a recent disease and recovery of Covid-19 as the only factor of inflammation and coagulation alteration. Other systemic diseases were excluded. We also describe a rapid decrease in disc and macular edema after intravitreal dexametasone injection, which could support the inflammatory hypothesis. The importance of this case lies in the possible association of papillophlebitis with the new Covid-19 disease. We believe that the inflammatory reaction and the coagulation alteration present in our patient due to Sars-Cov2 coronavirus may have acted as risk factors for the development of papillophlebitis.
