To investigate the association of binocular visual field defect and self-reported quality of vision (QOV) in patients with glaucoma.
Patients with diagnosed chronic angle closure or open angle glaucoma were recruited from a single tertiary ophthalmic department. Binocular logMAR visual acuity and Esterman binocular visual field tests were performed to objectively assess the daily useful visual function of the patients. Patients were then asked to rate their present quality of vision (QOV) on a scale of 0 (extremely poor vision with no light perception) to 100 (perfect vision), referred as linear rating scale utility test. Correlation between the indexes of objective visual function measurements and patient-perceived QOV were investigated.
A total of 133 glaucoma patients were enrolled in this study, which involved 75 males and 58 females with a mean age of 56±15 years. Of them, 77 (57.9%) were primary open angle glaucoma and 56 (42.1%) were chronic angle closure glaucoma. Ninety-eight patients (73.7%) presented with moderate or severe glaucoma according to the mean deviation (MD) in visual fields of the worse-seeing eye. The mean Esterman efficiency score was 92±12, with a maximum score of 100. Patients generated a score of 62±17 when asked to subjectively assess their own vision. This value was significantly correlated with monocular and binocular LogMAR visual acuity, MD and pattern standard deviation (PSD) in the visual field of each eye, and Esterman binocular visual field efficiency score. However, only Esterman binocular visual field efficiency score, visual acuity in the better-seeing eye, and MD of visual field in the worse-seeing eye showed significant association with the self-reported visual impairment score based on stepwise multiple linear regression model, with partial correlation coefficients (PCCs) of 0.316 (p<0.001), -0.308 (p<0.001) and 0.163 (p=0.05), respectively.
Binocular visual field is significantly correlated with glaucoma patients’ perception of visual impairment. When assessing the visual disability in patients with glaucoma, binocular visual field should also be considered to be an important index.
