AI Article Synopsis
- * Nine days after the surgery, she developed a pupillary block because of an anterior vitreous membrane, leading to another surgical procedure called anterior vitrectomy to alleviate this issue.
- * The patient's symptoms improved post-surgery, highlighting that while rare, pupil block complications can occur after total lens extraction, suggesting preventive measures like hyaloidotomy or iridectomy may be beneficial to avoid secondary issues.
Article Abstract
An 85-year-old Japanese woman with acute primary angle closure in her right eye underwent cataract extraction. Because of the weakness of the Zinn's zonules, all of the lens tissue including the lens capsule was removed by phacoemulsification. Because of the absence of vitreous prolapse into the anterior chamber, vitrectomy was not performed. Nine days postoperatively, acute angle closure due to pupillary block by an anterior vitreous membrane developed. To resolve the pupillary block, anterior vitrectomy was performed on the same day. Postoperatively, her symptoms resolved, the anterior chamber deepened, and the intraocular pressure normalized. Although rare, acute angle closure due to pupillary block by an anterior vitreous membrane can occur after total lens extraction with phacoemulsification. If no vitreous prolapse occurs with total lens extraction, an intentional hyaloidotomy using an anterior vitreous cutter or iridectomy should be considered to avoid secondary angle closure.

We report a case of acute angle closure secondary to pupillary block caused by a dislocated intraocular lens (IOL)-capsular tension ring (CTR) complex. A 68-year-old woman, who had undergone cataract surgery 28 months earlier, presented with acute right eye pain and blurred vision. Examination revealed elevated intraocular pressure (IOP) of 80 mmHg, corneal edema, and anterior chamber shallowing, with anterior displacement of the IOL-CTR complex observed on anterior-segment optical coherence tomography.

Article Synopsis
- The study compares clinical and genetic features of two Chinese children with type I sialidosis to previously reported cases, aiming to gather more insights into the disorder.
- The first patient, an 11-year-old girl, presented with short stature and vision problems linked to genetic mutations in the NEU1 gene, while the second patient, a 10-year-old boy, showed rapid weight gain and distinct visual impairments.
- Upon analyzing a total of 71 cases from the literature, common symptoms identified include muscle spasms and ataxia, highlighting the diverse manifestations of this genetic condition.
Process Evaluation of a Secondary School-Based Digital Behaviour Change Intervention to Improve Toothbrushing: The BRIGHT Randomised Controlled Trial.
Community Dent Oral Epidemiol

School of Clinical Dentistry, University of Sheffield, Sheffield, UK.
Article Synopsis
- - The study evaluated a behavior change intervention aimed at reducing dental caries in secondary school children in the UK, involving 4680 participants from 42 schools over 2.5 years, with a focus on schools with higher free school meal eligibility to address low household income.
- - Data collection included mixed methods such as self-reported questionnaires, staff feedback, and interviews to assess implementation fidelity, acceptability, and contextual factors surrounding the intervention.
- - While the intervention was mostly implemented as planned, challenges included inconsistent delivery of classroom sessions and technical issues with text messages; despite this, the intervention was generally deemed acceptable by participants.
