Glaucoma is a common ophthalmic condition, often associated with visual field defects and optic nerve damage. If left untreated, it can lead to permanent vision loss. In recent years, with the continuous advancement of artificial intelligence (AI) technology, its application in the field of ophthalmology has garnered increasing attention. Particularly, in the screening and diagnosis of glaucoma using fundus photographs, AI technology has shown tremendous potential. This section will review the progress of AI in utilizing fundus images for glaucoma screening and diagnosis.
Carbon dots or CDs is a new type of fluorescent carbon nanomaterial, which the diameter is generally less than 10 nm, has the advantages of self-fluorescence, remarkable biocompatibility, easy modification, low cost and so on, has a broad application prospect in the biomedical field. Local eye drops and vitreous drug injection (IVT) are the main modes of administration for ocular diseases. Due to the unique barrier structure of the eye, it is difficult for conventional drugs to reach the lesions through local eye drop administration, and for the drug residence time is short, patients have to increase the frequency of administration to maintain the drug efficacy. Up to now, the treatment of posterior eye diseases, such as diabetic macular edema (DME), choroidal neovascularization (CNV) and other diseases still rely on repeated vitreous injection, which is more traumatic, more side effects, and cause the heavier psychological and economic burden of patients. Optimizing the method of ocular drug delivery has always been a hot topic in the field of ophthalmology. Carbon dots have good permeability in the eye, showing excellent application potential in the ocular drug delivery, ocular imaging, and diagnosis and treatment of ocular disease. This review will systematically introduce the characteristics of carbon dots and the application of carbon dots and their nanomaterials in the biomedical field in the past ten years, focusing on the research progress of carbon dots in the diagnosis and treatment of eye diseases, aiming to provide a comprehensive understanding of the current situation of the application of carbon dots in ophthalmology and provide directions for future research.
Purpose: The aim of this study was to determine self-management and its association with self-efficacy and knowledgeamong glaucoma patients undergoing day surgery. Methods: A total of 223 glaucoma patients were recruited from September 2021 to May 2022，and they were investigated with the Glaucoma Self Management Questionnaire (GSMQ)，The Self-Efficacy in Chronic Disease Scale (SECD-6), and the glaucoma knowledge questionnaire. Results:Of the 223 study participants, the study population had a total GSMQ score of 54.03±6.95with the lowest score found in the life adjustment dimension. The total SECD-6 score was showing asignificantly positive correlation with the total GSMQ score（r=0.368, P＜0.001). The total score of disease knowledge was without significant correlation with the total GSMQ score (r=0.077, P=0.252). Multivariate linear regression analysis showed that self-efficacy and enducation level was independently associated with self-management (P<0.001, P=0.028).Conclusions:Glaucoma patients undergoing daytime surgery demonstrated good overall self-management, yet further improvement was required in terms of life adjustment. Low self-efficacy and educational level were identified as risk factors for self-management. Therefore, self-management programs should prioritize enhancing patients' self-efficacy and delivering individualized education.

Design: retrospective, nonrandomized, comparative study Participants: eyes enrolled were received cataract surgery with mfIOLs implantation with good recover from macular hole/ epiretinal membrane surgery. Methods: Analysis visual record, subjective refractive outcomes, complications from patients record meeting eligibility criteria (Group M), compare them to healthy subjects (Group C) with matching mfIOLs implantation. Main Outcome Measures: the primary effectiveness outcomes were UDVA, BCDVA, UIVA, UNVA, subjective refraction (sphere, cylinder, and spherical equivalent), defocus testing. Secondary effectiveness outcomes included Amsler grid test, surgical complications, and visual disturbances. Results: BCDVA postoperatively improved in both groups compared to the preoperative period (P=0.000). UCDVA postoperatively improved in both groups compared to the preoperative period (P=0.014 GroupM, 0.011 GroupC). The mean preoperative BCDVA in Group M and Group C was 0.26 ± 0.07 and 0.47 ± 0.29 logMAR, respectively. The mean postoperative BCDVA in Group 1 and Group 2 improved to 0.000 ± 0.037 and -0.04 ± 0.047 logMAR, respectively. The mean postoperative UDVA, UIVA, UNVA in Group M was 0.017±0.037, 0.033±0.094, 0±0.1 logMAR, the mean postoperative UDVA, UIVA, UNVA in Group C was 0±0.1, -0.067±0.047, 0.0167±0.107 logMAR, no significant differences were detected (P=0.349, 0.060,0.255). All patients in both groups achieved spectacles independence in daily life activity. No Visual Disturbances complaint was received. Amsler grid test was negative in all cases. Conclusions: MfIOLs implantation in eyes after macular surgery achieved similar visual function and spectacles independence to healthy eyes with preoperative assessment. Extra caution should be taken in post-vitrectomy eyes during phacoemulsification.
