The congenital cataract is one of the leading causes of treatable childhood blindness. Existing classification systems for congenital cataracts are primarily utilized for the diagnosis of the disease. However, these systems provide limited information necessary for the evaluation, formulation, and optimization of treatment plans. Furthermore, research on the classification of congenital cataracts still requires exploration to provide additional evidence supporting molecular diagnosis and syndromic disease diagnosis. This paper reviews relevant studies on the classification of congenital cataracts and discusses the prospects for future research in this area.

Objective: To investigate the advances and trends of heat shock proteins (HSP) in ophthalmology published from  2003 to 2023. Methods: The Web of Science database was used to retrieve the literature on heat shock proteins in ophthalmology published from January 1, 2003 to December 26, 2023. Bibliometric methods and VOSviewer and CiteSpaces software were used to analyze and visualize data, including publication count, countries, organizations, journals, authors, keywords and subject categories. Results: A total of 1079 publications related to HSP in ophthalmology were included, and the overall number of publications was fluctuating. The United States (n =394) was the leading contributor among countries. Investigative Ophthalmology & Visual Science (n =80) was the journal with the largest number of publications. The pathogenesis of glaucoma, the pathogenesis of cataract and the mechanism of ophthalmic diseases at the genetic level of HSP were identified as the research hotspots. Glaucoma, cholesterol, and molecular chaperones were identified as frontier research topics. Biochemistry & molecular biology, multidisciplinary materials science, and cell biology have the highest betweenness centrality values of 0.60, 0.28, and 0.26, respectively. Multidisciplinary chemistry (burst years: 2017 to 2023; strength = 6.3) was a subject involved in the research frontier of this field. Conclusion: Research on heat shock proteins in ophthalmology mainly focuses on revealing the genetic background of the diseases and exploring the molecular mechanisms and therapeutic applications in glaucoma and cataracts. The advance in the study on molecular mechanisms in this field depends on multidisciplinary collaboration.

内源性干细胞在组织的损伤修复过程中组织相容性好、致瘤风险低，相较于外源性干细胞具有不需要体外扩增和培养、疾病传播风险低的优点，在细胞治疗领域具有显著优势。现在已经有多种使用内源性干细胞进行疾病治疗的成熟方式，应用领域包括了全身各种器质性和功能性疾病。在眼组织中，晶状体具有终生生长的能力且便于观察，是实现再生修复的突破点。哺乳动物中晶状体再生的实现有赖于晶状体内源性干细胞的定位和改良手术方式，以保留晶状体干细胞，并创造适合晶状体再生的微环境。对再生后的晶状体蛋白质组成分析，发现其类似成熟晶状体，而非胚胎期的晶状体，提示晶状体再生的调控与胚胎期的诱导发生并不相同；而调控晶状体再生的策略不仅着眼于干细胞的激活和正确分化的诱导，对其上皮间质转化过程也需要进行调控。在未来，为将晶状体再生的经验应用于其他眼组织中，动员内源性干细胞并促进其生长，可以添加细胞有效成分，比如外泌体、线粒体、小分子化合物等，模拟细胞应激；此外，还可以通过手术或生物材料辅助，恢复晶状体结构和环境。

Endogenous stem cells have significant advantages in cell therapy for excellent histocompatibility, low tumorigenicity risk, unnecessity for in vitro expansion and culture, and low disease transmission risk. There have been some applications for endogenous stem cells in treating diseases, targeting some organic and functional diseases throughout the body. In ocular tissue, the lens is a breakthrough for regenerative therapy due to its potential to grow throughout life and observation accessibility. Achieving lens regeneration in adult mammals attributes to some prerequisites. Firstly, the location of endogenous stem cells in the lens has been identified. Then, surgical approaches have been advanced to preserve lens stem cells and create a microenvironment suitable for lens regeneration. Protein compositional analysis of the regenerated lens reveals that it is similar to a mature lens rather than an embryonic lens, suggesting that the regulation of lens regeneration is not the same as the induction of embryonic onset. The strategy for regulating lens regeneration needs to focus not only on the activation and proper differentiation of stem cells but also on regulating the process of epithelial mesenchymal transition (EMT). In the future, in order to apply the experiences of lens regeneration to other ocular tissues, to mobilize endogenous cells and promote their growth, some strategies could be used. These strategies include mimicking cellular stress via the addition of cellular active ingredients, such as exosome, mitochondria, and small molecular compounds. Additionally, we can also try to restore lens tissue structure and microenvironment through surgical or biomaterial assistance.
