Purpose : Cognitive impairment (CI) associated with aging can impair the ability of individuals to perform the visual field test and compromise the reliability of the results. We aim to evaluate the association between global neurocognitive impairment and visual field reliability indices in glaucoma patients
Methods : This prospective, cross-sectional study was conducted at the Ophthalmology department, Hospital Kuala Pilah, Negeri Sembilan. The study included 60 eyes of 33 glaucoma patients with no diagnoses of dementia. Patients were monitored with Humphrey visual field analyser using 24-2 strategy and CI was assessed using the clock drawing test (CDT). The relationship between the CDT score, fixation loss (FL), false positive (FP), and false negative (FN) percentages were analyzed using the linear regression model, adjusted for age.
Results : A high prevalence of cognitive impairment was observed in the glaucoma patient aged more than 65 years old. There was a statistically significant association between CDT score and False Negative and MD values. In a multivariate model adjusted for age, each one-point decline in CDT score associated with an increase of 1.5% in FN ((95% CI, 0.9-2.7; P=0.09) and increase of 0.2dB of MD value ((95% CI, 0.05-0.37; P=0.07).
Conclusion : Cognitive decline was associated with reduced visual field reliability during follow-up, especially with increased FN values. These findings suggest that screening and monitoring of cognitive impairment may be important in the assessment of visual field progression in glaucoma patients.
