Retrospective Analysis of Vision Rehabilitation for Veterans With Traumatic Brain Injury-Related Vision Dysfunction.

INTRODUCTION: Traumatic brain injury (TBI) can trigger vision-based sequelae such as oculomotor and accommodative abnormalities, visual-vestibular integrative dysfunction, visual field loss, and photosensitivity. The need for diagnosis and management of TBI-related vision impairment has increased because of the increasing frequencies of combat warfighters returning from Iraq and Afghanistan with TBIs. The purpose of this research was to learn the sequelae of rehabilitation service delivery to veterans with TBI-related visual dysfunction after they are diagnosed. To accomplish this, we investigated vision rehabilitation assessments and interventions provided to veterans with TBI-related visual dysfunction at the Department of Veterans Affairs (VA) specialty polytrauma facilities for the 2 years following their injury. The research questions asked what assessments, interventions, and prescribed assistive devices were provided by VA specialty clinics (e.g., occupational therapy, polytrauma, and blind rehabilitation) and how service delivery was affected by demographic and clinical variables. MATERIALS AND METHODS: A retrospective design was used to analyze VA data using natural language processing of unstructured clinician notes and logistic regression of structured data. Participants included 350 veterans with TBI who received rehabilitation at one of the five VA Polytrauma Rehabilitation Centers (Tampa, FL; Richmond, VA; Minneapolis, MN; San Antonio, TX; and Palo Alto, CA) between 2008 and 2017 and who were administered the 2008 congressionally mandated "Traumatic Brain Injury Specific Ocular Health and Visual Functioning Exam." The outcome variables were vision assessments, interventions, and prescribed assistive technology discovered via natural language processing of clinician notes as well as the vision rehabilitation specialty clinics providing the clinical care (polytrauma, occupational therapy, outpatient blind rehabilitation, inpatient blind rehabilitation, optometry, and low vision) extracted from VA structured administrative data. RESULTS: Veterans receiving rehabilitation for TBI-related vision dysfunction were most frequently assessed for saccades, accommodation, visual field, and convergence. Intervention was provided most frequently for eye-hand coordination, saccades, accommodation, vergence, and binocular dysfunction. Technology provided included eyeglasses, wheelchair/scooter, walker/cane, aids for the blind, and computer. There was an overlap in the services provided by specialty clinics. Services available and delivered were significantly associated with the comorbidities of each patient and the specialty clinics available at each VA Polytrauma Rehabilitation Center. CONCLUSIONS: The delivery of patient services should be driven by the needs of veterans and not by system-level factors such as the availability of specific vision rehabilitation services at specific locations. Traditional low vision and blind rehabilitation programs were not designed to treat the comorbidities and symptoms associated with TBI. To address this challenge, blind rehabilitation and neurologic recovery cross training is needed. Our findings document how five VA Polytrauma Rehabilitation Centers implemented this training in 2008. The next step is to extend and standardize this new paradigm to community care, where these post-deployment patients now reside.

Veterans with Traumatic Brain Injury-related Ocular Injury and Vision Dysfunction: Recommendations for Rehabilitation.

SIGNIFICANCE: We know the prevalence of traumatic brain injury (TBI)-related vision impairment and ocular injury symptoms. Lacking is an understanding of health care utilization to treat these symptoms. Utilization knowledge is important to structuring access to treatment, identifying clinical training needs, and providing evidence of the effectiveness of treatment. PURPOSE: This article reports rehabilitation, glasses/contacts, and imaging/photography/video recommendations made by optometrists and ophthalmologists as part of the Department of Veterans Affairs-mandated Performance of Traumatic Brain Injury Specific Ocular Health and Visual Functioning Examination administered to veterans with TBI at Department of Veterans Affairs polytrauma specialty facilities. METHODS: Using a retrospective design, natural language processing, and descriptive and regression statistics, data were analyzed for 2458 Operation Enduring Freedom/Operation Iraqi Freedom veterans who were administered the mandated examination between 2008 and 2017. RESULTS: Of the 2458 veterans, vision rehabilitation was recommended for 24%, glasses/contacts were recommended for 57%, and further imaging/photography/video testing was recommended for 58%. Using key words in the referral, we determined that 37% of veterans were referred to blind rehabilitation, 16% to occupational therapy, and 3% to low-vision clinics. More than 50% of the referrals could have been treated by blind rehabilitation, occupational therapy, or low-vision clinics. Rehabilitation referrals were significantly associated with younger age, floaters, photosensitivity, double vision, visual field and balance deficits, dizziness, and difficulty reading. In comparison, prescriptions for glasses and contacts were associated with older age, photosensitivity, blurred vision, decreased visual field and night vision, difficulty reading, and dry eye. Imaging/photography/video testing was associated with floaters, photosensitivity, and headache. CONCLUSIONS: Findings delineate service delivery models available to veterans with TBI-related vision impairment. The challenge these data address is the lack of clear paths from diagnosis of TBI to identification of vision dysfunction deficits to specialized vision rehabilitation, and finally to community reintegration and community based-vision rehabilitation.

Veterans with Traumatic Brain Injury-related Ocular Injury and Vision Dysfunction: Vision Rehabilitation Utilization.

SIGNIFICANCE: Visual dysfunction is frequently associated with traumatic brain injury (TBI). Although evidence regarding the prevalence of symptoms of this population has been published, little is known about health care utilization. A retrospective review of the data derived from the Department of Veterans Affairs (VA)-mandated "Traumatic Brain Injury Specific Ocular Health and Visual Functioning Examination for Polytrauma Rehabilitation Center Patients" provided a unique opportunity to investigate vision rehabilitation utilization. PURPOSE: The purpose of this study was to understand (a) the frequency of vision rehabilitation follow-up visits at 6, 12, and 24 months; (b) the association between follow-up and demographic, comorbidity, and severity of TBI covariates as well as ocular and visual symptoms, geographic access, and evaluating facility; and (c) why some veterans did not follow up with recommendations. METHODS: Retrospective and survey designs were used. The sample included 2458 veterans who served in the Operation Enduring Freedom/Operation Iraqi Freedom conflicts and received care at one of the five VA Polytrauma Rehabilitation Centers between January 1, 2008, and December 31, 2017. Quantitative and qualitative descriptive analyses and stepwise logistic regression were performed. RESULTS: About 60% of veterans followed up with recommended vision rehabilitation with visits equally split between VA Polytrauma Rehabilitation Centers and community VA facilities. For each 10-year increase in age, there was a corresponding reduction of 12% in the odds of follow-up. Veterans with decreased visual field had 50% greater odds of follow-up than those who did not. Veterans with difficulty reading had 59% greater odds of follow-up than those who did not. Those who had a double vision had 45% greater odds of follow-up than those who did not. CONCLUSIONS: Our findings suggest that the need for vision rehabilitation may extend as long as 2 years after TBI. Access to vision rehabilitation is complicated by the paucity of available neuro-optometric services.
