Eye surgery: Vitrectomy
If the abnormal blood vessels are leaking severely enough, they can rupture, causing a haemorrhage into the Vitreous cavity called a Vitreous haemorrhage. If it is mild, the eye will absorb it over a few months, but if it is severe, you might need to have surgery to remove the blood and fluid from your eye — a procedure called a Pars Plana Vitrectomy or PPV for short.
You can have either local or general anaesthesia. Through a tiny incision, your surgeon inserts a little instrument that removes the vitreous gel containing blood. He then replaces it with saline solution. Vitreous gel is mostly water anyway, so you will not notice any difference.
You can go home afterwards and will need to wear an eye patch for a week or two to protect your eye. It will be red and sensitive until it recovers.
