Issue highlightOccurrence of oculomotor dysfunctions in acquired brain injury: A retrospective analysis
Section snippets
Methods
A computer-based query was obtained for ABI patients examined between October 1, 2000, and October 7, 2003, using either the 99203 (new patient evaluation) or 99213 (established patient evaluation) procedure codes. All patients were ambulatory outpatients with vision-based symptoms. Optometrists from the Raymond J. Greenwald Rehabilitation Center (RJGRC) at the State University of New York (SUNY) State College of Optometry performed the vision examinations. The majority of patients were
Results
The percentage of individuals in the 2 subgroups manifesting the 5 basic categories of oculomotor dysfunctions are presented in Table 3. The majority of individuals with either TBI or CVA exhibited some type of oculomotor dysfunction. This ranged from 6.9% to 56.3% in the TBI subgroup and from 10.0 to 56.7% in the CVA subgroup. Deficits in accommodation (41.1%) and vergence (56.3%) were more prominent in the TBI subgroup, whereas those of strabismus (36.7%) and CN palsy (10%) were more
Discussion
The current retrospective analysis conducted in a large sample of ambulatory outpatients with either TBI or CVA and related vision symptoms supports previous reports of the markedly increased frequency of occurrence of oculomotor dysfunctions in these populations versus the non-ABI population.7, 9, 28 Furthermore, it extends these studies to include CVA, because CVA had not been investigated previously as its own subgroup.
