Statin users on average had 15 mm of total strabismus surgery compared with 21.4 mm in the nonuser group (P = 0.09) and had fewer muscles involved radiographically (4.3 vs 5.1 [P = 0.08]) CONCLUSIONS: Compared to nonusers, statin users tended to have fewer decompressions, less restriction, fewer surgeries, and fewer muscles involved despite having more current smokers (36% vs 5%), more males, more RAI, and fewer thyroidectomies, all of which are associated with worse TED.
