Retinal detachments were divided into two groups: eyes operated on from 1992 to 2001 (former AD group, n=63) and eyes operated on from 2002 to 2011 (recent AD group, n=38). We also reviewed the records of the first visit AD outpatients from 1993 to 2011 except 1998.Results: The percentage of bilateral detachment was significantly higher in the former AD group (14/63) than that in the recent AD group (0/38) (P=0.0002). In addition, patients in the recent AD group were significantly older than those in the former AD group (P=0.0084). The annual cases with non-AD retinal detachment remained invariant for 20 years. The ratio of the retinal detachment with AD for the total retinal detachment was significantly lower in the recent (38/847) AD group than that in the former (63/796) AD group (P=0.0038). The number of the first visit AD outpatients linearly decreased in these 19 years (153 cases in 1993 and 65 cases in 2011).Conclusion: Our study indicates an apparent decrease in retinal detachment with AD in the recent 10 years, and might suggest the importance of dermatitis control for prevention of retinal detachment with AD.Keywords: atopic dermatitis, incidence, ocular complication, retinal detachment

Per-oral endoscopic myotomy (POEM) is a minimally invasive treatment for esophageal achalasia. However, POEM has the potential risk of inducing carbon dioxide (CO 2 ) gas-related adverse events, such as pneumoperitoneum, pneumomediastinum, and pneumothorax. The aim of this study was to evaluate the usability of bladder pressure monitoring as an index of CO 2 gas-related pneumoperitoneum. The monitoring of bladder pressure and lung compliance and the incidence of iatrogenic pneumoperitoneum were retrospectively studied in 20 patients who underwent POEM between June 2013 and March 2015. The bladder pressure was measured using a Foley catheter. Abdominal distention was found in nine patients. The bladder pressure was significantly higher in the nine patients with the distention findings compared with patients without distention [7 (6-9) mmHg vs. 1 (0-2) mmHg; P < 0.05]; however, the decrease in dynamic lung compliance was not significantly different compared with patients without distention [- 7 (- 9.3 to - 5.1) vs. - 5 (- 10.2 to - 1.3) ml/cmH 2 O; P = 0.62]. Based on postoperative changes on CT scans; the following were the observations: pneumomediastinum (55%), minor pneumothorax (5%), pleural effusion (45%), atelectasis (15%), pneumoperitoneum (85%), and subcutaneous emphysema (15%). No significant clinical status was found among the patients postoperatively. Bladder pressure monitoring might be useful for detecting pneumoperitoneum during POEM.
