ABSTRACT
AIM: To analyze the characteristics and correlated risk factors of dry eye patients with corneal epithelial defects.METHODS: Outpatient medical records of dry eye patients with corneal epithelial defects at Peking University Third Hospital from July 2018 to June 2019 were retrospectively analyzed. The patients' data including sex, age, visit date, presence of comorbidities, and meteorological indicators at the same period were statistically analyzed.RESULTS: A total of 291 dry eye patients with corneal epithelial defects, of whom 75.3% were female, were retrospectively analyzed. Young patients aged 21-30 made up the most(26.5%), while the proportion of teenagers(<18 years, 5.8%)and the elderly(≥61 years, 17.2%)was low. However, as the largest proportion of this population, young and middle-aged patients tend to experience fewer visits(5.4±12.4). Spring and winter were the main seasons of complaints. The meteorological indicators at the same period including fine-particulate matter with a median aerometric diameter of less than 10μm(PM10), sulfur dioxide(SO2), nitrogen dioxide(NO2), and reduced average relative humidity were found significantly correlated with dry eye corneal epithelial defects(P<0.05). Conjunctivitis, cataracts, blurred vision, and trichiasis ranked the top four comorbidities.CONCLUSION: Dry eye corneal epithelial defects of young and female population cannot be ignored. PM10, SO2, NO2, and reduced humidity are found significantly correlated with dry eye corneal epithelial defects. For dry eye patients with conjunctivitis, cataracts, blurred vision, and trichiasis, more attention should be paid to their corneal conditions.
ABSTRACT
Lumbar disc herniation is an important cause of chronic low back pain, for which surgery has a great effect. However, there remain some residual symptoms, such as pain, disability, etc. It's effective for postoperative rehabilitation to relieve pain, and improve the disability and psychological status. However, the optimal rehabilitation program is controversial. So it's necessary to consider various aspects including time, site, frequency, intensity and pattern for an optimal rehabilitation choice, which needs further study. Psychological factors shall be concerned by medical workers as well.
