Adduction vs convergence

It should be noted that although adduction is impaired, convergence is often still intact. Eli6 03:42, 21 September 2006 (UTC)[reply]

Question

Question: The schematic is labelled right INO, but it looks like a left INO the way it's diagrammed. If I'm wrong, that's fine, but for the love of Duus, someone please explain it to me! xiggelee (talk) 17:16, 25 November 2008 (UTC)[reply]

When attempting to look left, a patient with right INO can only contract the lateral rectus and move the left eye, the medial rectus of the right eye can not contract so that eye stays midline. Fuzbaby (talk) 21:21, 5 June 2009 (UTC)[reply]

But the article says that adduction is impaired (moving into the centre). What you say, and what the diagram shows, is that abduction is impaired (moving away from the centre). Is the article wrong? Also, it would be great if a "simple English" explanation could be added on how to diagnose this for people who don't know Latin and Greek and don't want to click on 5-6 wikilinks to find out what the definitions mean.

The article is correct. Adduction is impaired: the eye that adducts only sees the nose so cannot remain fixed on target. It is normally led along by the eye being abducted, i.e. moving out of the centre. With an INO the nervous bundle that normally conveys this message is not working. The brain will then try to correct this by pulling the healthy eye back ("hold on a moment, the other eye can't catch up with you!") and that leads to "nystagmus" in the unaffected eye. Nystagmus is a type of eye flutter (often seen in people looking out of train windows). Savisha (talk)13:21, 26 January 2016 (UTC)[reply]
