Spinocerebellar ataxia type 7 is a form of spinocerebellar ataxia, which is a clinically and genetically heterogeneous group of rare inherited neurodegenerative disorders. Among the spinocerebellar ataxias, the association between cerebellar ataxia and cone-rod retinal dystrophy is a strong indicator of spinocerebellar ataxia type 7. Spinocerebellar ataxia type 7 cone-rod dystrophy is a progressive, disabling, and incurable form of hereditary retinopathy. However, the field of genetics has markedly progressed in the last decades, which resulted in improved understanding of multiple aspects of spinocerebellar ataxia type 7 retinal degeneration and the emergence of new modalities of genetic therapies for other types of retinal dystrophies. This study aimed to evaluate the current knowledge on spinocerebellar ataxia type 7 retinal degeneration, including genetics and molecular mechanisms as well as their implications in pathogenesis, clinical manifestations, and potential therapeutic strategies.

Purpose: The OrbiTau surgical simulator is a synthetic eye model developed to enhance cataract surgical training. Herein, we aimed to describe the perspectives of Harvard's Ophthalmology faculty and residents regarding the effectiveness of OrbiTau.

Methods: A cross-sectional study was conducted in which 11 surgeons from the Massachusetts Eye and Ear Infirmary, with prior experience utilizing simulated phacoemulsification platforms, conducted cataract surgery with the OrbiTau. Subsequently, they completed a satisfaction questionnaire using the Likert scale.

Results: Regarding the various OrbiTau components, 90.90% of the participants reported that the OrbiTau lens capsule was comparable to that of the human lens during capsulotomy. Furthermore, 72.72% of the participants found that the OrbiTau lens consistency was analogous to that of the human lens nucleus. Approximately 63.63% of the participants reported that the model's posterior lens capsule resembled the native posterior capsule, and 72.72% of the participants noted that the model's red reflex was similar to that of the dilated human pupil. Most participants believed that the OrbiTau was easier to use and more realistic than other commercially available simulators.

Conclusion: Our single-institution survey of the Orbitau demonstrated that this model realistically replicates ocular structures and may be a viable option for cataract surgery training.

This article systematically reviewed 327 documents in the core collection of the Web of Science database regarding ChatGPT applications in the writing domain. This study aimed to comprehensively assess the latest progress and potential applications. ChatGPT demonstrates significant potential in overcoming writing anxiety, improving writing efficiency, generating initial scientific papers, and assisting researchers and students in giving feedback. However, it still faces significant challenges in data accuracy and the ethics of generated content, including inaccurate or outdated information, plagiarism risks, gender or race biases, etc. Authorship verification is particularly important for academic writing and publishing as it relates to objectivity, accuracy, and fairness. Future studies need to explore how to address these challenges through improvements at the technical and policy levels, ensuring that ChatGPT promotes the sustainable development and application of academic writing while adhering to ethical standards.
