    Abstract Hereditary optic neuropathies (HONs) such as dominant optic atrophy (DOA) and Leber Hereditary Optic Neuropathy (LHON) are mitochondrial diseases characterized by a degenerative loss of retinal ganglion cells (RGCs) and are a cause of blindness worldwide. To date, there are only limited disease-modifying treatments for these disorders. The discovery of induced pluripotent stem cell (iPSC) technology has opened several promising opportunities in the field of HON research and the search for therapeutic approaches. This systematic review is focused on the two most frequent HONs (LHON and DOA) and on the recent studies related to the application of human iPSC technology in combination with biomaterials technology for their potential use in the development of RGC replacement therapies with the final aim of the improvement or even the restoration of the vision of HON patients. To this purpose, the combination of natural and synthetic biomaterials modified with peptides, neurotrophic factors, and other low- to medium-molecular weight compounds, mimicking the ocular extracellular matrices, with human iPSC or iPSC-derived cell retinal progenitors holds enormous potential to be exploited in the near future for the generation of transplantable RGC populations.

    Abstract Neurological manifestations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are relatively common. Although some may be consequences of direct cellular viral invasion (neurotropism), many represent post-infectious inflammation mediated by autoimmune mechanisms. We herein report the case of a 69-year-old diabetic male who presented with bilateral sub-acute, progressive loss of vision 45 days after suffering a presumed SARS-CoV-2 related pneumonia. He had bilateral optic disc oedema. Magnetic resonance imaging showed uniform contrast enhancement of both optic nerves without spinal cord involvement. He tested positive for SARS-CoV-2 IgG and myelin oligodendrocyte glycoprotein (MOG) IgG antibodies. He was treated with intravenous methylprednisolone for 5 days. The optic disc oedema resolved within 6 weeks with improvement in visual acuity, although optic atrophy developed by week 16. The MOG-IgG antibody test turned negative after 24 weeks.

    Abstract Introduction: Papillophlebitis is a rare condition characterized by venous congestion and optic disc edema, which has been suggested to occur as a consequence of inflammation of the retinal veins or, possibly, the capillaries of the optic disc, leading to venous insufficiency and compression of the central retina vein. 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.
    Case report: 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.
    Conclusion: 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.
