Brief Summary:
The purpose of the study was (1) to determine thresholds for discriminating speed in peripheral fields of patients with dry AMD and (2) to examine the driving skills of licensed drivers with early dry AMD using a driving simulator and to investigate how their healthy counterparts perform on the same driving tasks. We hypothesized that speed discrimination may be better in patients with dry AMD than in healthy control subjects.
Detailed Description:
This observational study has two goals:
1. to establish if patients affected by dry AMD have a different speed discriminating threshold using peripheral vision fields than their healthy counterparts.
2. to determine if the driving skills of AMD and glaucoma patients differ from healthy controls.
Two tasks will be used: 1) A speed discrimination test. (Glaucoma patient are not asked to perform this task as it assesses the peripheral visual fields, which is affected by the disease.) 2) A driving simulation session. Participant will undergo both tests on the same day, no later than a month after the initial recruitement visit.
For both diseases, patients will be compared to healthy controls matched for age and gender, but also to a younger control group. The latter group was added in order to take into account the normal aging impact on driving skills (visual and cognitive).
Our hypothesis is that AMD patient will show a better speed discriminating threshold than matched control and maybe better or equal to the younger control groups. We also hypothesize that driving skills involving peripheric speed awareness, such as passing another car, will be enhanced in the AMD group when compared to glaucoma patients and age-matched control group.
