    Abstract:
    PURPOSE: To investigate if optical quality assessed by Optical Quality Analysis System (OQAS) is a new factor for psychological disturbance and vision-related quality of life (QoL) in Chinese patients with primary open-angle glaucoma (POAG). METHODS: This is a cross-sectional study. OQAS, automated static perimetry, the Hospital Anxiety and Depression Scale (HADS) Questionnaire, and the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) were used to assess optical quality, visual field, psychological health, and QoL in 64 POAG patients. Correlation between the OQAS parameters and QoL or psychological health was analyzed by linear regression model. RESULTS: OQAS parameters, the modulation transfer function cutoff frequency (MTF cutoff) and the mean OQAS values (mean OV) were significantly related to mean deviation (MD). Statistically significant correlation was also found between MTF cutoff, the mean OV, and QoL in more than half of the NEI VFQ-25 subscale scores and the composite. The correlation coefficients between OQAS parameters and QoL were similar to those between MD and QoL in most of the subscale scores. HADS-Depression and HADS-Anxiety scores significantly correlated with MD in the worse eye, the composite and 3 subscales of NEI VFQ-25, general health, social function, and mental health, but were not correlated with optical quality parameters measured by OQAS. CONCLUSIONS: OQAS-assessed optical quality is negatively related to MD and is a valid indicator for vision-related QoL, but not for psychological health in our study group. OQAS might be an alternative or supplement to perimeter in POAG patients.
