I really find mnemonics like "to find ocular melanoma doing imaging" really unintuitive (for me, at least)
So with some thinking, and some assistance from language models (though they're mostly unhelpful), I came up with something that jives with me more.
Think of it like you're receiving a quest in a game

"Use melanoma fluid to (2) see 50 (20/50) oranges
Find five wide hollow ones to ultrasound."
Ocular Melanoma signs
- 2mm fluid
- 20/50 visual acuity
- Orange color
- 5mm wide
- Hollow on ultrasound
