This review seeks to fill in this gap by first systematically reviewing the current literature on GenAI in medical paper writing. It identifies and discusses nine key applications and considerations, including idea generation, literature review, institutional review board preparation, data collection, data analysis, image generation, manuscript drafting, writing refinement, and peer review. In the second part, we explore publicly available AI tools that currently assist with medical manuscript writing. We also introduce several generative AI detection tools and discuss their accuracy and reliability. Finally, the review addresses the limitations and ethical challenges associated with the use of GenAI in medical paper writing. While GenAI has streamlined many aspects of medical paper writing, and an increasing number of AI tools have been developed for research, significant model limitations and ethical concerns persist, necessitating careful human oversight and clear guidelines. By providing a comprehensive yet focused overview, this article offers valuable insights into the effective use of GenAI in medical paper writing while acknowledging its limitations and risks.

While gene therapy addresses specific mutations, cell replacement strategies offer a potentially broader solution applicable across multiple genetic causes. This review traces the evolution of retinal transplantation approaches, from early fetal tissue transplants to modern pluripotent stem cell-derived retinal organoids. The development of three-dimensional retinal organoids marked a significant advancement, providing transplantable tissue that maintains cellular architecture and relationships. Preclinical studies have demonstrated that transplanted organoids can develop mature photoreceptors with outer segments, form synaptic connections with host bipolar cells, restore light responsiveness in host retinal ganglion cells, and enable light-responsive behaviors in animal models. The first human clinical application using induced pluripotent stem cell-derived retinal organoids has demonstrated safety and stable graft survival over 2 years, with potential functional improvement in one patient at around 1 year after transplantation. Recent innovations include genome-edited retinal organoids with reduced competing bipolar cells, which enhance functional integration by increasing host-graft connectivity. While significant challenges remain, including increasing transplantation area, improving surgical techniques, optimizing patient selection, and addressing manufacturing and regulatory considerations, continued progress in this field may offer hope for some visual improvement in currently untreatable retinal degenerative conditions.</p>","PeriodicalId":44978,"journal":{"name":"Taiwan Journal of Ophthalmology","volume":"16 3","pages":"424-434"},"PeriodicalIF":1.4,"publicationDate":"2025-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13668185/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149196399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Population-based studies report a wide variation in MMD prevalence, ranging from 0.24% in rural India to 4.5% in mainland China. MMD is etiologically heterogeneous, with its prevalence associated with a more negative spherical equivalent (SE), longer axial length (AL), older age, and a lower education level.

PCR can result from various factors, weak zonules, posterior polar cataracts, including improper phacoemulsification techniques, and excessive instrument manipulation. Early recognition is critical, and swept-source optical coherence tomography and intraoperative assessments can enhance early detection. Prevention strategies focus on meticulous surgical planning, careful hydrodissection, judicious use of phaco power, and maintaining anterior chamber (AC) stability. Techniques such as slow-motion phacoemulsification, femtosecond laser-assisted cataract surgery (FLACS), and capsule-stabilizing devices can reduce the risk of PCR in high-risk cases. Once a rupture occurs, prompt and careful management is essential to prevent further complications such as vitreous loss, retained lens fragments, or intraocular lens (IOL) malposition. Anterior vitrectomy using bimanual or coaxial techniques is crucial for clearing vitreous from the AC and preventing traction on the retina. The choice of IOL implantation depends on the extent of PCR, with options including sulcus-fixated, iris-fixated, scleral-fixated, or ACIOLs when capsular support is inadequate.
