FTIR spectroscopy is a novel technique for detection of metastatic lymph nodes and may prove useful in surgery for papillary thyroid cancer.

PurposeTo assess the vision-related quality of life and self-reported driving performance of patients with dry eye disease (DED).Patients and methodsThe study was performed in the eye centre of Peking University Third Hospital, China. In total, 87 dry eye patients and 42 controls were enroled, including 49 patients without any treatment (group A), 38 patients treated with artificial tears (group B) and 42 controls without DED (group C). The participants had no eye disease other than DED. Scores of a vision-related quality-of-life questionnaire (Ocular Surface Disease Index (OSDI)), a daily life-related visual function questionnaire and a questionnaire about performance during driving were collected. Data were compared among the groups and analysed.ResultsSignificant differences in all clinical characteristics and OSDI scores were found between DED patients and normal controls (P<0.05). While subjects in group A felt more uncomfortable than those in group B, the functional limitations related to dry eye were significant in all DED patients, especially for daily work and using a computer. DED was correlated with unsafe driving habits and performance, which may increase the risk of dangerous driving (P<0.01). For patients with DED, the rate of accidents and near-accidents was 10.33%, and the rate of missed targets totalled 32.17%.ConclusionsDED can lead to many inconveniences in daily life, including driving. The frequencies of unsafe driving habits and performance were increased in patients with DED.
