Condition guide
The rating criteria are only part of the picture for Vision Loss. The Vision Loss condition page covers service connection, common evidence problems, secondary conditions, and Board outcome patterns in depth.
What happens to Vision Loss appeals at the Board
Claim Raven's analysis of 5,025 decided Board of Veterans' Appeals rulings on Vision Loss, 2021 to 2026. The Vision Loss condition page has the full breakdown, including which evidence types are associated with better outcomes.
Method: each ruling's outcome is read from the order in the Board's published decision and rolled up as granted (including partial grants), denied, or remanded, leaving out dismissals and withdrawals. The data codes the condition the Board ruled on, not the diagnostic code, so these numbers describe Vision Loss appeals generally rather than DC 6066 specifically. Board outcomes describe appealed claims, not initial decisions.
