Publication Case Report of Foveolitis with Optic Neuritis: A Barely encountered Ophthalmic Manifestation of Dengue(Institute of Medicine, 2023) Bista, Bipin; Sitaula, Ranju Kharel; Lama, Dichen M; Sitaula, SanjeetaABSTRACT Dengue fever is a tropical disease which is endemic in tropical/subtropical nations like Nepal. Bilateral optic neuritis with unilateral foveolitis is an unusual dengue-related ophthalmic complication. We here present to you a case of bilateral optic neuritis with right eye foveolitis who initially presented with complaints of sudden diminution of vision in one eye following dengue fever. This report deals with prolonged treatment of rare ocular presentation of dengue infection. Patient had persistent myodesopsia and scotoma in the right eye even after 5 months of treatment with oral steroids. Dengue-related ophthalmic findings although rare, can have significant and long-lasting visual impairment if not treated timely and appropriately. Keywords: Dengue; foveolitits; optic neuritisPublication Ocular and Neuro-ophthalmic Manifestations Post COVID-19 Infection(Nepal Health Research Council, 2023) Bista, Bipin; Yadav, Reena; Gupta, Sharad; Das, Sandip Sanyam; Rajak, Ashik; Acharya, Rajesh; Neupane, Rasik; Bista, Padam RajAbstract A 39-year-old male with a history of COVID-19 infection presented with ocular manifestations: dendritic ulcer in the left eye cornea followed by diplopia in the same eye. Extraocular motility was restricted in the levo-lateral gaze with maximum diplopia measuring 25? exotropia. Slit lamp biomicroscopy showed dendritic patterned lesion with diffused superficial punctate keratitis in the cornea. There are various reports associated with COVID-19 and the neuro-ophthalmic system. Although the clinicopathological aspect of COVID-19 and the neurological system is still to explicate. However, the patient showed gradual improvement with topical and systemic antiviral therapy and orthoptic exercise. This points to the need for detailed neurological and ophthalmic workup in symptomatic COVID-19 patients. Taking the risk of viral spread into serious consideration, a thorough evaluation is though mandatory. Keywords: COVID-19; dendritic ulcer; lateral rectus palsy; superficial punctate keratopathy
