The follow-up time was 72mo.Functional sucess was defined as the disappearance of epiphora under normal conditions and the presence of a patent ostium on lacrimal irrigation. Anatomical success was defined as a patent lacrimal passage on syringing besides continuing epiphora. Surgical failure was defined as persistent epiphora and closed ostium.RESULTS：Twenty-seven of 40 patients （67.5%） were female and 13 of 40 patients （32.5%） were male. The NDO was right-sided in 17 （42.5%） patients and left-sided in 22（55%） patients whereas 1 （2.5%） patient had undergone bilateral surgery. In 11 （27.5%） patients there were additional nasal abnormalities requiring simultaneous surgical approach. The average time for L-DCR was 26.50±4.9min（16-39min） and the average total amount of laser energy used was 287±27.9 J （239-367 J）. At the 5y follow-up, anatomical sucess rate was 75.0%（30 patients） and functional success rate was 65.0%（26 patients）, whereas surgical failure was seen in 25%（10 patients）. Revision of surgery was performed in 10 cases （25.0%）; failure of revision surgery was seen in 2 cases（5.0%）.CONCLUSION： Transcanalicular L-DCR is a reliable and fast procedure in the treatment of NDO. It can be alternative to external DCR which is accepted as the gold standard currently. The functional and anatomical success rate is higher in the first months and years, but still satisfactory at fifth year.展开更多

Methods: A retrospective study was conducted between January 2017 and January 2018 on a total of 110 infants with 35 or less gestational weeks. The sample included 78 infants who had been diagnosed with different stages of ROP and 32 infants without ROP. Results from routine serum biochemical analyses, performed at birth and at one month after birth, were evaluated. The Independent Sample t-test and Mann-Whitney U test were performed to compare the data. Results: The infants with ROP were born at a mean of 28.0 (±2.1) weeks of gestation, weighing a mean of 1066 (±314) g, and the mean duration of stay in the incubator was 38.2 (±19) days. The infants without ROP were born at a mean of 29.6 (±2.6) weeks of gestation, weighing a mean of 1265 (±372) g. 59 infants (53.6%) were females, and 51 (46.4%) were males. Between infants with and without ROP, differences in the following levels were not statistically significant: glucose, blood urine nitrogen, creatinine, alanine aminotransferase, aspartate aminotransferase, albumin, total protein, direct bilirubin, indirect bilirubin, uric acid, and phosphorus. Serum magnesium (Mg) levels at birth in infants with ROP were significantly higher than infants without ROP (p = 0.014). Conclusions: Serum Mg levels at birth were found to be higher in infants with ROP than in those without ROP. The levels may be dependent on the mothers’ treatment of Mg for different medical reasons.展开更多
