A patient's personality may influence self-reported symptoms and self-reported quality of life.

In a sampling of glaucoma patients, respondents classified as "neurotic" on the Neuroticism, Extraversion and Openness Personality Inventory Revised (NEO P-IR) test were more likely to respond negatively to questions on the National Eye Institute's Visual Function Questionnaire (VFQ).

A classification of "conscientiousness" on the NEO P-IR was found to have a positive correlation with results from the VFQ. Researchers also noted a correlation between "extraversion" on NEO P-IR and VFQ scores.

Previous studies have linked clinical depression as a confounding factor in VFQ scores. In the current study, personality had a smaller impact on quality-of-life reporting than visual acuity, but was found to be more significant than other variables, notably age, gender, ethnicity, level of education, number of comorbid conditions, total number of medications and eye visual-field measurements.
