Glaucomatous retinal nerve fiber layer thickness loss is associated with slower reaction times under a divided attention task.

ABSTRACT:

Purpose

To examine the relationship between glaucomatous structural damage and ability to divide attention during simulated driving.

Design

Cross-sectional observational study.

Methods

Setting

Hamilton Glaucoma Center, University of California San Diego.

Patient population

Total of 158 subjects from the Diagnostic Innovations in Glaucoma Study, including 82 with glaucoma and 76 similarly aged controls.

Observation procedure

Ability to divide attention was investigated by measuring reaction times to peripheral stimuli (at low, medium, or high contrast) while concomitantly performing a central driving task (car following or curve negotiation). All subjects had standard automated perimetry (SAP) and optical coherence tomography was used to measure r
