Red-eye
From Tardis Wiki, the free Doctor Who reference
Red-eye was a disease found amongst enslaved Ood on their homeworld of the Ood Sphere. Its symptoms were bright red eyes, rabid temperment and anti-Human sentiment.
It was caused by the subconscious of the Ood Brain reemerging amongst the Ood after 200 years of slavery and the sabotage of Ood Operations's systems by the Friends of the Ood. However, similar symptoms occured in the Ood serving the Walker Expedition on Krop Tor. It would later lead to the Battle of the Ood Sphere in 4126 and the freedom of the Ood. (DW: Planet of the Ood)
