Retinitis pigmentosa (RP) is a genetically determined degenerative retinal disease characterized by primary progressive degeneration of rod and secondary degeneration of cone photoreceptors. Despite the fact that the central retinal zone remains relatively intact for a long time, the most common complication of RP is macular edema (ME). The causes of ME in patients with RP have not been finally established, and treatment approaches are controversial. This article presents the modern data on the pathogenesis, clinical aspects, diagnostic, and treatment methods of ME associated with RP.
Despite dominant lung lesions, new coronavirus infection (COVID-19) can influence almost any organ, including eyes. According to modern data, frequency of eye damage by COVID-19 reaches 32%, and spectrum of clinical manifestations is diverse. Changes are observed both in the anterior (mainly conjunctivitis) and posterior (mostly retinal vascular thrombosis, optic neuritis, neuroretinitis) segments of the eye, and the timing of their occurrence varies from the first (sometimes the only) clinical symptoms of the disease to the development at the peak or during the period of convalescence from COVID-19.
In children symptomatic COVID-19 infection is diagnosed less frequently than in adults, and ophthalmic manifestations are less investigated. This article describes a case of bilateral neuroretinovasculitis in a 17-year-old girl with a mild course of COVID-19, that arose 3 weeks after the onset of the disease, which broadens the understanding of ocular manifestations of COVID-19 in children.
We emphasize that an ophthalmologist should know ocular manifestations of COVID-19, which can help in the diagnosis and further study of the frequency and spectrum of ophthalmic symptoms, especially in children
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
