Pathogenic Ocular Dissonance is the third studio album by the American Christian metal band Tourniquet.

It was independently re-released on Pathogenic Records in 2001 with digital remastering, two bonus live tracks from the 2000 Dutch Flevo Festival featuring then-lead vocalist Luke Easter, and new cover art (with "Dissonance" misspelled as "Dissonence" on the tray liner edges).

Retroactive Records released a Collector's Edition remaster on June 26, 2020 with the original cover art, an expanded album booklet, and four different bonus tracks.

Pathogenic Ocular Dissonance was voted as the "Favorite Album of the 1990s" by readers of HM Magazine.

In 2010, HM Magazine ranked it #23 on the Top 100 Christian metal albums of all-time list.

The band's characteristical style of incorporating classical music into its guitar riffs is especially reminiscent on the beginning of the title track.

The album introduced more Slayer-esque shouting vocal patterns by Gary Lenaire as well as a darker atmosphere.

However, during an interview with HM Magazine in 2007 he clarified: It [leaving the band] was actually right after we finished [the recording of the album].

But I learned a style of singing and tried to write the songs that I wrote for Tourniquet on guitar because I felt like it was a tool to reach people.

The album's final song "The Skeezix Dilemma" uses the board Uncle Wiggily's (also a children's book series by Howard Roger Garis) concept as an allegory for child abuse.

The song starts out with a minute of circus music (organ played by Bob Beeman) which is followed by a nervous child reading a bit of the game's introduction.

2 and features vocalist Les Carlsen of the American Christian metal band Bloodgood; this track was later included on the 2020 remaster along with three instrumental demos.
