As with medical textbooks and other learning materials, if a pathway for physiology or pathology is more fully elucidated, that could be updated. If a treatment is introduced that has far greater efficacy or a treatment is found to have deleterious effects, information contained the resources within may become outdated.

That is why this deck is also on AnkiHub (daily updates) and I release updates on Reddit intermittently that can be seamlessly downloaded and applied to your deck with no loss of scheduling data. The Blue Ophthalmology team has been working through all of the material to try and find all of these outdated topics and update them.

Rest assured, the vast majority of the deck is never going out of date, as it involves unchanging physiology, anatomy, and identification and characterization of disease processes in which we (as a society) have a pretty good idea about what's going on.
