Vision therapy as part of neurorehabilitation after acquired brain injury - a clinical study in an outpatient setting

Efficacy of restitutive interventions for oculomotor deficits in adults with mild traumatic brain injury: a systematic review and meta-analysis

BACKGROUND

Mild traumatic brain injury (mTBI) can cause persistent symptoms suggestive of oculomotor deficits. This research synthesized evidence on restitutive interventions for reducing oculomotor deficits in adults with mTBI to understand if these interventions have clinical utility for improving recovery.

METHODS

Medline, EMBASE, CINHAL, PsychInfo, and Scopus, databases were searched for experimental studies published in English. We rated risk of bias (RoB) using recommended tools, and the certainty of the evidence according to GRADE guidelines. We conducted meta-analyses for similar outcomes reported in at least two studies.

RESULTS

Out of 5,328 citations, 12 studies (seven case series and five crossover design), with a combined sample size of 354 participants; (43% males) met the inclusion criteria and were analyzed. The analysis revealed a trend toward improvement of oculomotor deficits and visual tasks in response to restitutive intervention. None of the studies addressed sex or gender effects. All studies had high RoB, suggesting low certainty in the reported results.

DISCUSSION

Restitutive interventions may be beneficial for adults with oculomotor deficits after mTBI, however overall certainty of the evidence remains low. Future efforts must include enhancing attention to study methodology and reporting, sex and gender analyses, and reaching a consensus on outcome measures.

Clinical Practice Guidelines for Occupational Therapists in the Evaluation and Treatment of Oculomotor Impairment Following Traumatic Brain Injury

Purpose of review

Currently, a lack of guidelines exists regarding best practices for occupational therapists (OTs) in the treatment and evaluation of oculomotor dysfunction following traumatic brain injury (TBI). Furthermore, individuals with TBI would benefit significantly from collaboration between OTs and optometrists during inpatient rehab.

Recent findings

Although few articles examine interdisciplinary models of inpatient rehab care that include optometry, a recent pilot study is explored. Emerging evidence from the field of optometry supports the use of restorative approaches for oculomotor impairment in mild TBI; however, cases with moderate to severe TBI are not addressed.

Summary

We describe an interdisciplinary approach involving collaboration between optometry and occupational therapy, yielding a comprehensive model to effectively evaluate and treat oculomotor impairments in those with TBI and facilitate improved performance in daily activities. We also provide guidelines useful for OTs working in settings where collaboration with optometry is not feasible.
