A 60-year-old woman presented with a complaint of gradual loss of vision in her right eye over the past 3 days. She reported a sensation of a ‘curtain’ coming from the right inferotemporal side towards the centre, along with flashes of lights at the right inferotemporal side and an increase in the number of floaters in her right eye. Upon examination, her vision in the right eye was measured at 6/18, while her left eye was 6/6. What is the most likely diagnosis?
