There were no differences in serum calcium, phosphate, and B-ALP between the two groups. Sun exposure was significantly longer in the vitamin D-sufficient group compared with that in the non-vitamin D-sufficient group (511.4 vs. 318.7 min/weeks, p = 0.004), and this effect remained consistent on multivariate analysis after adjustment to covariates (adjusted OR 1.002, 95% CI 1.000-1.003). More subjects in the vitamin D-sufficient group did not use sunscreen (59 vs. 27, p=0.02), but this finding is inconsistent with multivariate analysis.

Despite year-round sun exposure, approximately 1 in 3 primary school-aged children had insufficient vitamin D levels. Sun exposure duration was a major contributing factor.

The information of 2 078 479 patients who underwent cataract extraction of 31 provinces (municipalities and autonomous regions) recorded in the National Cataract Surgery Information Reporting System during January to December, 2017 were analyzed. The postoperative visual outcomes of 3 days after surgery and 3 months after surgery were analyzed. The effects of age, gender, preoperative corrected visual acuity, past medical history, and surgical methods on the results of cataract surgery were analyzed. Surgery effect was divided into ideal effect, moderate effect and poor effect according to the best corrected visual acuity after operation. Wilcoxon rank sum test and multinomial logistic regression model were used for statistical analysis. Results There were 1 197 942 female patients (57.64%) and 880 537 male patients (42.36%) in all 2 078 479 cases. The average age was (69±11) years oever, some patients still suffer moderate visual impairment. The effect of surgery can be affected by many factors, such as preoperative corrected visual acuity, preoperative intraocular pressure, preoperative pupil status, surgical approach and postoperative complications, etc. (Chin J Ophthalmol, 2021, 57 63-70).Objective To analyze the distribution characteristics of the anterior corneal astigmatism in 140 000 cataract patients from 18 hospitals in China. Methods Retrospective study. A total of 143 889 patients (143 889 right eyes) over the age of 40 years with age-related catarac were admitted to 18 Aier eye hospitals in China from July 2015 to October 2018. The average values of the three measurements of the magnitude of anterior corneal astigmatism, the meridian of corneal astigmatism, anterior chamber depth, corneal refractive power, and axial length measured by IOLMaster 500 were obtained. The data acquisition method of each sub-center was to collect and analyze the electronic case data in accordance with the inclusion and exclusion criteria, and to provide them for the sponsor Wuhan Aier Eye Hospital. Non-normal distribution data are presented as M (P25, P75). Mann-Whitney test, Kruskal-Wallis test, Chi-square test were used to analyze the distribution differences of the magnitude of corneal astigmatism and the meridian of corneal astigmatism in gender, age, anterior chamber depth, corneal refractive power and axial length. Results Among the 143 889 patients, 84 319 were females and 59 570 were males, the median age was 72 (65, 78) years old, the median corneal astigmatism was 0.84 (0.51, 1.33) D; the corneal astigmatism was ≥0.75 D in 80 895 patients (56.22%) and was ≥1.00 D in 57 304 patients (39.83%). The median corneal astigmatism was 0.87 (0.53, 1.37) D in women and 0.82 (0.50, 1.29) D in men; with statistical difference (U=-14.891; P25.00 mm, both the magnitude of corneal astigmatism and the proportion of ATR astigmatism reach the peak. (Chin J Ophthalmol, 2021, 57 56-62).Objective To compare the difference and agreement of corneal refractive power and astigmatism measured by the new swept-source anterior segment optical coherence tomography (SS-AS-OCT) device (CASIA2) and Scheimpflug imaging device (Pentacam) in age-related cataract patients. Methods In this cross-sectional study, 112 eyes of 112 patients with age-related cataract were examined before phacoemulsification in the Tianjin Medical University Eye Hospital from April to May 2020. The steep keratometry (Ks), flat keratometry (Kf), mean keratometry (Km), degree and axis of astigmatism of the corneal anterior and posterior surfaces and the total cornea were recorded. The difference in astigmatism was analyzed by the arithmetic method and the vector method. The difference of data was evaluated using Paired t test or Wilcoxon test. The agreement of data was evaluated using Bland-Altman plots. Results The patients were 44 males and 68 females with an average age of (67±10) years. There were no statistically differences i, 0.06 to 2.27 D, and 0.10 to 2.20 D, respectively, with a wide 95%LoA range and poor consistency. Conclusions The corneal refractive power and astigmatism measured by the CASIA2 and the Pentacam shows little difference on the anterior surface of the cornea, with good agreement. However, the refractive power results of the posterior surface of the cornea and the total cornea show great difference, suggesting that these two instruments cannot be used interchangeably in clinical practice.

Methods Prospective cohort study. EPZ5676 Histone Methyltransferase inhibitor The subjects came from a finished multicenter, randomized and controlled clinical trial with a follow-up period of 1 year from April to November 2012. The clinical research centers were Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Peking University Third Hospital, Tianjin Medical University Eye Hospital, and Daping Hospital of Army Medical University. Cataract patients in the experimental group were implanted with A1-UV type IOL, while cataract patients in the control group were implanted with SN60WF type IOL, and monocular patients were enrolled. From April to May 2018, patients enrolled in the previous study were recalled for follow-up and continued observation. The visual acuity, spherical equivalent, postoperative complications, non-contact intraocular pressure and subjective evaluation results were statistically analyzed preoperatively, at 1 to 2 days, 1 week, 1 month, 3 months, 6 months, 1 year and 5 years after operation.
