A 67-year-old woman presents with a complaint of seeing an ‘arc of white light and some cobwebs’ in her vision with eye movements in her left eye for the past week. She also reports that her vision in the left eye is now very blurry. She denies any recent trauma and has a history of myopia in both eyes. Her past medical history is unremarkable. On examination, her left eye has a visual acuity of 6/18 while her right eye has a visual acuity of 6/6. Both anterior segments appear normal. However, on dilated fundoscopy, the view of the left fundus is blocked by some red and grey matter in the vitreous while the right fundus is unremarkable. What is the next most appropriate management step to determine the underlying cause of the findings in the left fundus?
