Migraine Secondary to Conjunctivitis, chronic
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 Conjunctivitis, chronic.
Primary condition · VASRD 6019
Conjunctivitis, chronic
Ongoing inflammation of the eye lining causing redness and discomfort.
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 Conjunctivitis, chronic — severity of Migraine itself determines the percentage.
Example combined rating
10% Conjunctivitis, chronic + 30% Migraine = 37%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 10% and 30% combine to 37%, not 40%. 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
- •Employer or family statements about missed work or functional episodes
