全眼球移植的历史进展与现存挑战

Historical advancement and current challenges in whole eye transplantation

:1-7
 
全眼球移植(Whole eye transplantation, WET)是治疗因外伤、肿瘤等导致眼球不可逆损伤及永久性失明的潜在终极手段。其核心不仅在于实现眼球解剖结构的完整移植,更关键的是实现功能性视觉恢复,关键挑战包括优化手术策略重建眼球血液循环,实现供体视神经与受体视觉中枢的神经连接,建立精准有效的免疫调控策略以平衡移植耐受与感染风险。本文系统梳理了WET领域的研究进展与发展挑战。早期研究以变温动物模型为主,这些模型在一定程度上证实了视觉通路在眼球移植后仍具有一定的可塑性,但由于其眼球结构与人类存在显著解剖差异,且实验设计中未涉及精细的血管与神经吻合,因而临床转化价值有限。随着显微血管技术的发展,哺乳动物模型及人眼球移植的初步探索在显微外科血管吻合技术方面取得重要突破,实现了移植眼球视网膜血液灌注的短期重建,但仍面临视神经再生障碍和功能维持难题。当前的研究瓶颈主要集中在三个方面:血液循环重建技术优化、神经轴突精准再生及免疫微环境调控。建立与人类接近的标准化非人灵长类动物模型,并开展系统性的实验研究,将为克服现有技术障碍、推动WET走向临床提供至关重要的实验依据和新思路。
Whole eye transplantation (WET) is a potential definitive treatment for irreversible ocular damage and permanent blindness caused by conditions like trauma or tumors. The success of WET depends not only on the complete anatomical restoration of the transplanted eye but, more critically, on the recovery of functional vision. Key challenges in this field include optimizing surgical strategies to re-establish ocular blood circulation, achieving functional neural integration between the donor optic nerve and the recipient's visual centers, and developing precise and effective immunomodulation strategies to strike a balance transplant tolerance and infection risk. This review provides a systematic review of the research progress and developmental challenges in the field of WET. Early studies primarily utilized poikilothermic animal models, which demonstrated a certain degree of plasticity in the visual pathway following transplantation. However, due to significant anatomical differences compared to humans and the lack of sophisticated vascular and neural anastomosis in experimental designs, their clinical translatability of these studies remained constrained. With the progress in microvascular techniques, preliminary explorations in mammalian models and human eye transplantation have achieved significant breakthroughs in microsurgical vascular anastomosis, enabling the short-term reestablishment of retinal blood perfusion in transplanted eyes. Nonetheless, perisitent obstacles include inadequate optic nerve regeneration and poor long-term functional maintenance. Currently, research bottlenecks mainly focus on three aspects: optimizing surgical techniques for blood circulation reconstruction, precisely regenerating nerve axons, and regulating the immune microenvironment. Establishing standardized non-human primate models that closely mimic humans and conducting systematic experimental studies will furnish crucial evidence and novel insights to overcome existing technical hurdles and propel WET toward clinical application.

Objective: To assess the instructional efficacy of the EYESi surgical simulator in training ophthalmology residents on vitreoretinal surgical procedures. Methods: Fifteen ophthalmology residents participating in standardized specialist training program at Zhongshan Ophthalmic Center, Sun Yat-sen University, were randomly assigned to three groups (A, B, C; n=5 per group). All participants underwent an initial baseline assessment through simulated retinal detachment surgery. In addition to standard training modules covering posterior vitreous detachment, anterior retinal membrane peeling, and inner limiting membrane manipulation, Group A received supplementary bimanual scissors training, Group B underwent laser training, and Group C received both types of advanced training. The final assessments were carried out using the same retinal detachment simulation, with performance scores and operation times carefully recorded. Results: Post-training surveys revealed significant increases in both trainees’ self-confidence and their self-assessed surgical proficiency. Objective performance scores for retinal detachment surgery showed marked improvement after training (P < 0.001). Groups C and A achieved significantly higher final scores compared to Group B (P < 0.05). Participants with prior intraocular surgical experience scored higher and completed procedures more quickly in the baseline assessment than those without such experience (P < 0.05). Conclusions: The EYESi simulator proves to be an effective tool for enhancing surgical skills and boosting operational confidence in vitreoretinal surgery training. In particular, bimanual instrumentation training offers significant educational value in the development of advanced microsurgical techniques.

Objective: To investigate the current status and identify the influencing factors regarding the knowledge, attitudes, and practices related to dry eye disease (DED) among patients. This study aims to provide a solid foundation for the development of targeted clinical interventions. Methods: With convenience sampling, patients diagnosed with DED were selected at the Dry Eye and Ocular Surface Disease Clinic of Zhongshan Ophthalmic Center from January to March 2025 as study subjects. The survey tools consisted of a general information questionnaire, the Chinese Dry Eye Questionnaire, and the Knowledge, Attitudes, and Practices (KAP) Questionnaire for DED patients. The KAP questionnaire was structured into three dimensions: knowledge (16 items), attitudes (7 items), and practices (9 items), making a total of 32 items. Univariate analysis and multiple linear regression were employed to identify influencing factors. Results: A total of 325 valid questionnaires were collected. Among the 325 DED patients, the average KAP score was 62.89±9.00, and the standardized score was 78.61±11.25, indicating a moderate level. In the knowledge dimension, the average score was 9.89±4.88 and 134 patients (41.2%) had poor scores. The attitudes dimension showed a relatively high level, with a total mean score of 26.92±2.24 and a standardized score of 96.16±8.03, reflecting that the patients generally held positive attitudes towards the prevention and treatment of DED. For the practices dimension, the total mean score was 26.06±5.43, and the standardized score was 72.41±15.09, indicating a moderate level of behaviorial practices. Univariate analysis revealed significant differences in KAP scores among patients with different ages, education levels, monthly household income per capita, frequencies of electronic device use, and whether they actively sought disease-related knowledge (P<0.05). Further, age, education level, and proactive information-seeking behavior were identified as significant influencing factors for KAP scores (P<0.05). Conclusions: The KAP level of DED patients is moderate. Their disease knowlege is fragmented, while they exhibit positive attitudes toward prevention and treatment. However, their behavioral practices are subptimal and are influenced by multiple factors. Therefore, it is essential to develop tailored and personalized health education programs to enhance the KAP level of DED patients.

Outcomes of Coaxial Micro-incision Phacoemulsification in Nanophthalmic Eyes: Report of Retrospective Case Series

Outcomes of Coaxial Micro-incision Phacoemulsification in Nanophthalmic Eyes: Report of Retrospective Case Series

:94-100
 
Purpose: The surgical risk and complication rate after cataract surgery are extremely high in patients with nanophthalmos. This study is designed to compare the visual and refractive outcomes before and after coaxial micro-incision phacoemulsification and evaluate postoperative complications.
Methods: Fifty nine patients (89 eyes) with axial length (AL)<21 mm diagnosed with nanophthalmos were enrolled in this retrospective study. All patients underwent coaxial micro-incision phacoemulsification and IOL implantation. The main outcome measures included anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), intraocular pressure (IOP) and best corrected visual acuity (BCVA). Wilcoxon signed rank test or Mann-Whitney test, and Chi-square test and logistic regression analysis were performed for statistical tests as appropriate.
Results: The median AL was 19.63 mm. Sixty-six eyes (74.16%) had a history of surgical intervention. Postoperative ACD, ACV and ACA were increased significantly (all P<0.001), whereas postoperative IOP was decreased significantly. (P< 0.001) after surgery. Previous surgical intervention was related to a reduction in the postoperative ACD and ACA (P<0.01), and both preoperative and postoperative IOP (P<0.001). Postoperative BCVA was improved in 94.38% of the cases. Intraoperative complications mainly included iridoschisis (6 eyes, 6.74%). Early postoperative complications included temporary corneal edema (TCE) (23 eyes, 25.84%), anterior inflammatory response (AIR) (19 eyes, 21.35%), cystoid macular edema (CME) (14 eyes, 15.73%), and uveal effusion (4 eyes, 4.49%). Late postoperative complications included CME (8 eyes, 8.99%),  uveal effusion (8 eyes, 8.99%), malignant glaucoma (2 eyes, 2.25%) and posterior capsular opacification (PCO)(10 eyes, 11.24%). The majority of complications (80%) were successfully resolved by pharmacotherapy or operation. The risk of surgical complications was greater in patients with lower AL, ACD, ACV or ACA and higher nuclear hardness or mean keratometry (Km).
Conclusion: With reasonable preoperative management, prudent selection of the lens, rigorous surgical technique and unerring cognition of potential complications, coaxial microincision phacoemulsification lens surgery can be performed in patients with nanophthalmos and yield favorable outcomes and a low incidence of complications.
