FWIW, no mention of that incident here: Marty Feldman - Wikipedia
In play:
Also per Wiki: British actor Marty Feldman suffered from thyroid disease and developed Graves’ ophthalmopathy, causing his eyes to protrude and become misaligned. A childhood injury, a car crash, a boating accident and reconstructive eye surgery may also have contributed to his appearance. He later described his appearance as a factor in his career success: “If I aspired to be Robert Redford, I’d have my eyes straightened and my nose fixed and end up like every other lousy actor, with two lines on Kojak. But this way I’m a novelty.”
