ABSTRACT
INTRODUCTION: An isolated posterior capsule rupture (PCR) is a rare complication associated with traumatic cataracts. We report our findings in three cases of traumatic cataracts with isolated PCR caused by blunt ocular trauma. PRESENTATION OF CASES: Case 1: A 1.5-year-old boy was examined after his parents noticed that the center of the pupil of the left eye was white. The mother reported that the boy had fallen and bruised his left forehead 4 months earlier. Case 2: An 18-year-old boy had a traumatic cataract that developed one month after a blow to his eye. Case 3: A 13-year-old boy was treated for hyphema and high intraocular pressure after blunt trauma to his eye. Ten days later, a total cataract developed. Anterior segment optical coherence tomography revealed an isolated PCR with a protruding lens cortex, and ultrasonography showed vitreous opacities. DISCUSSION: An isolated PCR was observed intraoperatively in the center of the posterior lens capsule. The lens cortex was prolapsed into the PCR or into the vitreous cavity in Case 3. An intraocular lens (IOL) was implanted in the lens capsule or to the ciliary sulcus after vitrectomy in Case 3. Vision improved in all eyes. CONCLUSIONS: Our findings indicated that the external force by a trauma to the eye can lead to an isolated PCR with a protruded lens cortex in young patients. These PCRs can be successfully treated with the IOL implanted in or out of the capsular bag.
ABSTRACT
Background: The Japanese Circulation Society 2022 Guideline on Perioperative Cardiovascular Assessment and Management for Non-Cardiac Surgery standardizes preoperative cardiovascular assessments. The present study investigated the efficacy of a large language model (LLM) in providing accurate responses meeting the JCS 2022 Guideline. MethodsâandâResults: Data on consultation requests, physicians' cardiovascular records, and patients' response content were analyzed. Virtual scenarios were created using real-world clinical data, and a LLM was then consulted for such scenarios. Conclusions: Google BARD could accurately provide responses in accordance with the JCS 2022 Guideline in low-risk cases. Google Gemini has significantly improved its accuracy in intermediate- and high-risk cases.
