A 47‑year‑old female came with a history of loss of vision in the right eye since 4 days. It was sudden in onset and painless. She gave history of consulting an ophthalmologist within 12 h of visual loss and was treated with ocular massage and systemic acetazolamide. Within 24 h of initiation of treatment, the temporal half of vision was spontaneously restored partially. Anterior segment examination was unremarkable in both eyes. Visual acuity by Snellen’s chart at presentation to us in right eye was 6/18, N10 and intraocular pressure by applanation tonometry was 12 mmHg. Right eye fundus picture is given below [Figures 1 and 2]. Optical coherence tomography (OCT) of the macula [Figure 3] and fundus fluorescein angiography was performed to confirm the diagnosis.
