The Impact of Location of Progressive Visual Field Loss on Longitudinal Changes in Quality of Life of Patients with Glaucoma.


Journal Article

PURPOSE: To evaluate the association between rates of progressive loss in different regions of the visual field and longitudinal changes in quality of life (QoL). DESIGN: Prospective, observational cohort study. PARTICIPANTS: The study included 236 patients with glaucomatous visual field loss followed for an average of 4.3±1.5 years. METHODS: All subjects had the 25-item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25) performed annually and standard automated perimetry (SAP) at 6-month intervals. Subjects were included if they had a minimum of 2 NEI VFQ-25 and 5 SAP tests during follow-up. Evaluation of rates of visual field change was performed using 4 different regions (central inferior, central superior, peripheral inferior, and peripheral superior) of the integrated binocular visual field. The association between change in NEI VFQ-25 Rasch-calibrated scores and change in different regions of the visual field was investigated with a joint multivariable longitudinal linear mixed model. MAIN OUTCOME MEASURES: The relationship between change in QoL scores and change of mean sensitivity in different regions of the visual field. RESULTS: There was a significant correlation between change in the NEI VFQ-25 Rasch scores during follow-up and change in different regions of the visual field. Each 1 decibel (dB)/year change in binocular mean sensitivity of the central inferior area was associated with a decline of 2.6 units/year in the NEI VFQ-25 scores (R(2) = 35%; P < 0.001). Corresponding associations with change in QoL scores for the peripheral inferior, central superior, and peripheral superior areas of the visual field had R(2) values of 30%, 24%, and 19%, respectively. The association for the central inferior visual field area was statistically significantly stronger than those of the central superior area (P = 0.011) and peripheral superior area (P = 0.001), but not the peripheral inferior area (P = 0.171). Greater declines in NEI VFQ-25 scores were also seen in patients who had worse visual field sensitivity at baseline. CONCLUSIONS: Progressive decline in sensitivity in the central inferior area of the visual field had the strongest association with longitudinal decline in QoL of patients with glaucoma.
