Ultrawide field imaging with navigable magnifier for diagnosis of diffuse unilateral subacute neuroretinitis

Description

A 52-year-old female presented with painless loss of vision in right eye since 3–4 years. Visual acuity was counting fingers close to face in right eye and 20/20 in left eye. Anterior segment examination and intraocular pressure were normal in both eyes. Right eye had multiple areas of pigment mottling and deep retinal scarring scattered throughout the fundus, along with optic disc atrophy (figure 1). Fundus examination of left eye was unremarkable. Window defects were detected on ultrawide field fluorescein angiography. Diffuse unilateral subacute neuroretinitis (DUSN) was suspected due to the ultrawide field imaging (UWFI) characteristics. The clinical UWFI was scanned with a navigable magnifier available in the software (Optos PLC, Dunfermline, UK). A slender, white-coloured, minimally curved structure was identified in the temporal pre-equatorial region with an adjoining scar (figure 2).
