Abstract
Methods
The present retrospective study was conducted on 78 eyes in 39 patients diagnosed with thyroid-associated ophthalmopathy. The risk factors for dry eye in thyroid-associated ophthalmopathy patients were examined by analyzing data including tear breakup time, Schirmer's test, age, gender, thyroid function status, palpebral fissure width, lagophthalmos, eyelid retraction, and exophthalmos through multiple logistic regression analysis.
Results
The risk factors for dry eye disease were palpebral fissure width (OR = 3.422, p = 0.022) and lagophthalmos (OR = 13.068, p = 0.049). Age, gender, thyroid hormone status, eyelid retraction and exophthalmos did not show significant association with dry eye in multiple logistic regression analysis. The only risk factor for tear film breakup time less than 10 seconds was palpebral fissure width (OR = 2.787, p = 0.045), and none of the risk factors for Schirmer's test less than 10 mm at 5 minutes were statistically significant.
