Senior Music Writer and Chief Music Critic

Elton John announced on his social media on Tuesday that he has spent the summer "quietly at home" recovering from "a serious eye infection" that has left him with limited vision in the affected eye.

The announcement comes just three days before John is set to make a public appearance at the premiere of a documentary at the Toronto International Film Festival. John’s rep tells Variety that he will still be in Toronto for the unveiling of “Elton John: Never Too Late” on Sept. 6, as planned.

“Over the summer,” John wrote in his social post, “I suffered a serious eye infection which unfortunately has left me with limited vision in one eye. I am healing but it is an extremely slow process and it will take some time for the vision to return in the affected eye. I am so grateful to the wonderful team of doctors and nurses and my family who have looked after me so well over the last few weeks.
