Difficulty with dark adaptation may lead to driving cessation in patients with glaucoma

Patients with moderate/severe glaucoma questioned in a cross-sectional survey reported a higher percentage of driving cessation and a higher percentage of difficulty with dark adaption and glare compared to those with mild glaucoma.

Ninety-nine participants with glaucoma (57% female) older than 50 years were included and classified into two groups: mild (53 participants, MD greater than -6 dB) and moderate/severe (46 participants, MD -6 dB or less).

Researchers utilized the Glaucoma Quality of Life-15 questionnaire and the glare and dark adaptation subscales to measure relevant visual disability and driving cessation, and difficulty was determined through the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ). Nondrivers were excluded from the analysis.

When compared to participants with mild glaucoma, those with moderate/severe glaucoma reported a significantly higher percentage of driving cessation (33% vs. 8%), presence of glare (27% vs. 6%) and difficulty with dark adaptation (31% vs. 10%).

Age, sex and best corrected visual acuity were not associated with driving cessation, according to researchers.

Those with self-perceived difficulty with dark adaption or glare were not significantly more likely than those without to quit driving.  Participants with self-perceived difficulty with dark adaptation were about four times more likely than those without to experience difficulty driving at night or in poor conditions, according to the study. In addition, those with moderate/severe glaucoma reported a higher percentage of driving cessation versus patients with mild visual field loss….
