Older drivers' self-reported vision-related night-driving difficulties and night-driving performance.

Purpose: To investigate associations between older drivers' perceived vision-related night-driving difficulties and night-time driving performance measured on a closed-road circuit.

Methods: Participants included 26 older drivers (71.8 ± 6.

Nighttime Driving in Older Adults: Effects of Glare and Association With Mesopic Visual Function.

Purpose: To examine the associations between nighttime driving performance of older drivers and photopic, mesopic, and glare-based tests of visual function.

Methods: Participants included 26 older drivers (71.8 ± 6.

Development and validation of a vision and night driving questionnaire.

Purpose: Night-time driving difficulties are a common concern of older drivers and those with eye disease. This study aimed to develop and validate a questionnaire for assessing vision-related night driving difficulties in older drivers.

Methods: Items from existing vision-related quality of life questionnaires and driving studies were used to develop a questionnaire that was completed by 283 participants who reported visual difficulties for night driving (65% female, 50 to >80 years).

Stepping accuracy and visuomotor control among older adults: effect of target contrast and refractive blur.

Purpose: Older adults have increased visual impairment, including refractive blur from presbyopic multifocal spectacle corrections, and are less able to extract visual information from the environment to plan and execute appropriate stepping actions; these factors may collectively contribute to their higher risk of falls. The aim of this study was to examine the effect of refractive blur and target visibility on the stepping accuracy and visuomotor stepping strategies of older adults during a precision stepping task.

Methods: Ten healthy, visually normal older adults (mean age 69.

Apparent inferior rectus palsy with gaze-dependent sensory adaptations.

Purpose: This report presents a case of apparent congenital inferior rectus palsy notable for sensory adaptations that appeared to vary with direction of gaze. It is shown that readily available clinical tests and an understanding of the physiology of ocular motility can be used to help distinguish from differential diagnoses such as contralateral inferior oblique palsy or the more commonly seen Brown syndrome.

Case Report: A 20-year-old male optometry student reported strabismus that had been noted at birth and was diagnosed as Brown syndrome in childhood.
