[The influence factors of quality-of-life in patients with thyroid-associated ophthalmopathy].

ABSTRACT

Objective: To assess the risk factors associated with decreased quality-of-life in patients with thyroid-associated ophthalmopathy (TAO). Methods: Cross-sectional study. One hundred and twelve patients with TAO and 68 controls were recruited to answer the Graves' ophthalmopathy quality-of-life questionnaire (GO-QOL) from January 2014 to April 2016. The GO-QOL included two subscales the visual functioning and the psychosocial consequences. The differences in the GO-QOL scores between TAO patients and controls were analyzed. The influences of multiple factors on the GO-QOL scores among TAO patients were explored. Results: Among 112 TAO patients, 63 were male and 49 were female, with an average age of (45.4±13.1) years. Among 68 controls, 36 were male and 32 were female, with an average age of (39.5±10.8) years. Independent sample t test showed that TAO patients had significantly lower scores than controls in the visual functioning subscale and the psychosocial consequences subscale (55.63±29.02 vs 97.48±6.96, t=-14.58, P<0.01; 57.61±29.97 vs100±0.00, t=-14.97, P<0.01). Among TAO patients, smokers were associated with significantly lower psychological subscale scores than non-smokers (t=-2.284, P=0.024). Patients with abnormal primary position of eye scored significantly lower than those with normal alignment in functional (t=-3.979, P<0.001) and psychological subscales (t=-2.154, P=0.034) Patients with abnormal eye movement had significantly lower functional scores than those without (t=-2.975, P=0.004). One-way analysis of variance showed that higher CAS scores were significantly related to lower psychological subscale scores (F=3.178, P=0.018). Patients with upper eyelid retraction had significantly lower psychological subscale scores than those without (F=3.562, P=0.032). Pearson correlation analysis showed that age was negatively correlated with functional subscale scores (r=-0.366; P<0.01). TAO course was negatively correlated with functional (r=-0.235, P<0.05) and psychological subscale scores (r=-0.320, P<0.01). The degree of exophthalmos was negatively correlated with psychological subscale scores (r=-0.209, P<0.01). Multivariable linear regression analysis showed that only primary position of eye (P=0.013) and TAO course (P=0.007) were negatively correlated with functional subscale scores and only CAS scores (P=0.022) and TAO course (P=0.024) were negatively correlated with psychological subscale scores. Conclusion: Risk factors associated with lower quality-of-life among TAO patients included abnormal primary position of eye, higher CAS scores, and longer TAO course.(Chin J Ophthalmol,2017,53 575-582).
