Visual Psychophysics / Physiological Optics - ARVO

ARVO 2013 Annual Meeting Abstracts by Scientific Section/Group – Visual Psychophysics / Physiological Opticssituation. Follow ups where through the local optometrist (7/10).They thought highly of the questionnaire and emphasized the needfor regular follow up of optometrists with low vision advices as ahealth speciality.Conclusions: To enhance better low vison rehabilitation and toprovide better work situationsis it necessary to look at the work andthe home situation together. There is a need for a systematic approachtowards this patient group. The optometrist is essential in optical lowvision follow up, the NLW-LWC needs to focus on technical support,illumination, legal rights and the dialog with the work place. Ourquestionnaire can be a tool of care. To improve the rehabilitation atwork you improve selfesteem and paricipation in the society.Commercial Relationships: Jørn Kalleberg, None; IreneLangeggen, NoneProgram Number: 2781 Poster Board Number: B0035Presentation Time: 8:30 AM - 10:15 AMThe effect of an Adapted Day Centre on Physical andPsychological Well-Being in Older Adults with Low VisionWalter Wittich 1, 2 , Caitlin Murphy 3, 2 , Daphne Mulrooney 1, 2 .1 Research, MAB-Mackay Rehabilitation Centre, Montreal, QC,Canada; 2 CRIR, Montreal, QC, Canada; 3 School of Optometry,University of Montreal, Montreal, QC, Canada.Purpose: Older adults with visual impairment are vulnerable tosocial isolation and associated health risks. The MAB-MackayRehabilitation Centre runs a Day Centre program whose objectivesare to maintain or improve the seniors’ biological, psychological, andsocial health, and foster a better quality of life, while delaying oravoiding institutionalization. Activities include walking groups,language courses, memory games, crafts and theme parties,supervised by an interdisciplinary team, including a nurse, socialworker and occupational therapist. Services include medical andrehabilitation follow-up and referrals to additional communityresources. The present study evaluates the impact the Day Centre hason the holistic health of older adults with visual impairment.Methods: Between September 2011 and October 2012, 16 newlyreferred clients in the Day Centre (age 71 to 98, M = 85, VA 20/50 toNLP, M = 20/126) were evaluated at intake, and after 6 months,using the Visual Function Questionnaire-14, Hearing HandicapInventory for the Elderly, Geriatric Depression Scale (GDS),Friendship Scale, Life-Space Questionnaire, Activity-specificBalance Confidence scale, Timed-Up-and- Go Test, and the adaptedMontreal Cognitive Assessment (MoCA). Acuity, visual field, andaverage decibel hearing loss were recorded.Results: All participants continued to live independently in thecommunity 6 months after entering the Day Centre. Comorbidconditions included high blood pressure, asthma, cardiac problems,diabetes, stroke, arthritis, osteoporosis, and anxiety. Participantsreported statistically unchanged scores on all the measures, except forincreased GDS scores (p < .05) and a trend towards improvement onthe MoCA (p = .06).Conclusions: Considering the fragility, vulnerability and age of thispopulation, the data indicate that the Day Centre fulfills its mandateto prevent decline in its clients’ biological, psychological, and socialhealth. We speculate that the increase in depression scores is linkedto serious life events during the follow-up period for some of theparticipants, such as loss of a spouse. Participation in adapted DayCentre activities, as an integrated part of rehabilitation services,seems to support independent living in older adults with vision loss.Commercial Relationships: Walter Wittich, None; CaitlinMurphy, None; Daphne Mulrooney, NoneProgram Number: 2782 Poster Board Number: B0036Presentation Time: 8:30 AM - 10:15 AMVision, Demographic Factors, and Motor Vehicle Collisions inBioptic DriversBradley E. Dougherty 1 , Roanne E. Flom 1 , Mark A. Bullimore 2 ,Thomas W. Raasch 1 . 1 Optometry, Ohio State University, Columbus,OH; 2 Optometry, The University of Houston, Houston, TX.Purpose: In approximately 40 US states, drivers who cannot meetvision standards with conventional optical correction are permitted touse bioptic telescopic spectacles to obtain licensure. Very few studiesof safety of bioptic driving have been conducted. This studyexamined the relationships among visual and demographic factorsand motor vehicle collisions (MVC) in bioptic drivers in Ohio.Methods: A retrospective study of patients identified as havingreceived an initial daylight bioptic examination at the College ofOptometry at the Ohio State University was conducted. Data werecollected on vision, including visual acuity (logMAR charts), contrastsensitivity (Pelli Robson or Mars charts) and visual field (arc orGoldmann perimeter). Driving records from the Ohio BMV wereobtained and demographics, ocular diagnoses, and licensure historywere also recorded. Relationships among vision, demography, andBMV data including MVC were investigated using survival analysisand the Cox proportional hazards regression model.Results: 238 drivers (65% male) were identified. Age at initial examranged from 16 to 81 years (mean = 39±15 years). Time since biopticlicensure ranged from 1 to 22 years (mean = 10±5 years). MeanlogMAR visual acuity OU was 0.76±0.12 (approximately 20/115)and mean log contrast sensitivity was 1.53±0.23. A total of 292 MVCwere documented in the BMV records for these drivers. The numberof MVC per driver ranged from 0 to 11, with 124 (52%) drivershaving had at least one MVC and 72 (30%) having had two or more.Visual acuity, contrast sensitivity, and horizontal visual field werenot significant predictors of MVC (p = 0.81, 0.18, and 0.76,respectively). Gender was not associated with MVC (p=0.28), butage was associated with fewer MVC (p < 0.001). Previous (withoutbioptic)licensure status was associated with fewer MVC (p < 0.001),with 41% of drivers with previous licensure involved in an MVCversus 67% of drivers without previous licensure.Conclusions: Age and previous non-bioptic licensure were inverselyassociated with fewer MVC in this group of bioptic drivers. VA, CS,horizontal VF, and gender did not predict MVC involvement.Commercial Relationships: Bradley E. Dougherty, None; RoanneE. Flom, None; Mark A.

Chan, Robert W. Massof, Judith E. Goldstein.Ophthalmology, Johns Hopkins University School of Medicine,Baltimore, MD.Purpose: We reported that physicians’ ability to predict the successof low vision rehabilitation (LVR), relative to patient-reportedoutcomes, is no better than chance. This study determines if patients’traits influence ratings physicians provide and if those traits affectpatient-reported outcomes.Methods: The Activity Inventory (AI), a self-report visual functionquestionnaire, was administered pre and post-LVR to 270 low visionpatients served by 28 LVR centers that participated in a collaborativestudy.
