Migraine Secondary to Impairment of Central Visual Acuity
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 Impairment of Central Visual Acuity.
Why Migraine Is Linked to Impairment of Central Visual Acuity
Eye strain
Primary condition · VASRD 6077
Impairment of Central Visual Acuity
This code rates central visual acuity, how sharply you can see fine detail, using a detailed table that combines your best-corrected vision in each eye, rather than the simpler correctable-versus-not distinction used by some other vision codes. If your rating decision cites this code, both eyes' specific Snellen chart results (like 20/40 or 20/70) are what determines your tier.
Secondary condition · VASRD 8100
Migraine
Severe recurring headaches that may include nausea, light sensitivity, and inability to function.
Migraine VA Rating Tiers
The VA rates Migraine the same way whether it's claimed directly or as secondary to Impairment of Central Visual Acuity — severity of Migraine itself determines the percentage.
Example combined rating
30% Impairment of Central Visual Acuity + 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.
Evidence for a Migraine Secondary Claim
- •Neurology consult with detailed migraine history
- •Headache diary showing frequency and impact
