Ronald Derise appeals the denial of his claim for Social Security disability benefits. We affirm for the reasons given by Magistrate Judge Wilson in his thorough report, as adopted by the district court.

Our review is limited to determining whether the Commissioner’s decision is supported by substantial evidence and free of legal error. Jones v. Apfel, 174 F.3d 692, 693 (5th Cir. 1999). Ronald Derise is blind in his right eye and can no longer work as a truck driver. Relying on a vocational expert, the ALJ determined that there are a significant number of jobs in the national economy that he can still perform. Derise urges that the ALJ improperly relied upon the vocational expert’s testimony because that testimony was flawed, having failed to list any specifically available jobs as required by SSR 85-15. Yet Derise does not explain how this procedural impropriety casts doubt on the existence of substantial evidence or otherwise effects his substantial rights.

“Procedural perfection in administrative proceedings is not required. This court will not vacate a judgment unless the substantial rights of a party have been affected.” Mays v. Bowen, 837 F.2d 1362, 1364 (5th Cir. 1988). Such procedural improprieties “constitute a basis for remand only if such improprieties would cast into doubt the existence of substantial evidence to support the ALJ’s decision.” Morris v. Bowen, 864 F.2d 333, 335 (5th Cir. 1988). *420 Derise has not cast doubt upon the ALJ’s decision. The judgment of the district court is

AFFIRMED.
