Acute Unilateral Vision Loss and Optic Perineuritis (OPN) in Geriatric Patients, a Series of Three Cases

Background: Optic Perineuritis (OPN) is an uncommon condition associated with many systemic disorders. Methods: We report three geriatric patients with acute unilateral vision loss and OPN. We also included a brief literature review pertinent to OPN. Results/Discussion: While OPN has been reported in association with many conditions such as giant cell arteritis (GCA), it is infrequently associated with mucormycosis sinusitis. Here, we presented cases of OPN associated with both GCA and mucormycosis infection of the sinuses. Conclusions: OPN is an be idiopathic a variety disorders. Early and this condition and its causes are necessary to prevent permanent vision loss. Even though many different can overall, the prognosis of OPN remains good save mucormycosis associated with OPN where the prognosis is generally poor.
