The 77-year-old music legend, who retired from touring last year, sounds upbeat despite his illness and has explained he intends to attend upcoming work commitments.

Sharing his news via Instagram on Tuesday, the Rocket Man singer revealed, "Over the summer, I've been dealing with a severe eye infection that has unfortunately left me with only limited vision in one eye. I am healing, but it's an extremely slow process and it will take some time before sight returns to the impacted eye."

He continued, "I am so grateful for the excellent team of doctors and nurses and my family, who have taken such good care of me over the last several weeks."

And he signed off the message by writing, "with love and gratitude."

Variety reports that, despite this setback, the star plans to attend the premiere of his documentary, Elton John: Never Too Late, at the Toronto International Film Festival on September 6.

The documentary, which will be available on Disney+ in December, offers an intimate look at Elton's life and career, including his farewell show at Dodger Stadium.

An eye infection is not the only ailment Elton has battled recently as earlier this year the star revealed he was recovering from knee replacement surgery.
