Secondary Condition Claim · VASRD 8100
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Migraine when it develops after Eye Condition – Loss of Visual Field.
Ocular strain
Primary condition · VASRD 6078
Eye Condition – Loss of Visual Field
You’ve lost part of your side (peripheral) vision.
Secondary condition · VASRD 8100
Migraine
Severe recurring headaches that may include nausea, light sensitivity, and inability to function.
The VA rates Migraine the same way whether it's claimed directly or as secondary to Eye Condition – Loss of Visual Field — severity of Migraine itself determines the percentage.
Example combined rating
30% Eye Condition – Loss of Visual Field + 30% Migraine = 51%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 30% and 30% combine to 51%, not 60%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
