Each fellow performed 127 ERM surgeries (total: 508). Learning progression was rated using an 18-item Likert scale (1-5; higher scores = greater difficulty). Primary outcomes included visualization quality, surgical comfort, and instructor interaction. A linear regression model assessed learning trends.Results: Fellows using the digital system achieved proficiency within three months, compared to seven months for the analog group. Initial difficulty scores were significantly lower in the digital group (1.64 vs. 5.14, p<0.001). Monthly improvement rates were -0.30 (digital) vs. -0.86 (analog). Instructor interventions were higher in the analog group during the first six months (p<0.05) but equalized later. Early ergonomic and comfort advantages with digital systems also leveled over time.Conclusions: Digital HUD systems enhance early skill acquisition and reduce learning-related challenges in retina fellow training. Although long-term proficiency equalizes, these systems offer clear early-phase benefits, supporting their integration into surgical education.","PeriodicalId":19595,"journal":{"name":"Ophthalmologica","volume":" ","pages":"1-19"},"PeriodicalIF":1.9,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145244799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to assess the long-term outcomes of SMH patients managed with anti-VEGF monotherapy (MT) versus surgical displacement (SD) and to identify prognostic factors for visual acuity. Methods This multicenter retrospective study included patients with SMH secondary to nAMD treated in three hospitals in Lyon between 2018 and 2023. Patients were treated with MT or underwent pneumatic displacement (PD) or SD. The best-corrected visual acuity (BCVA) and clinical parameters were assessed at baseline (time of SMH onset), months 1, 3, 9 and 12. Results Sixty-six eyes were included: 33 received MT, 6 underwent PD, and 27 underwent SD. The baseline VA was strongly reduced (mean BCVA: 0.14). The VA improved to 0.21 at M1, 0.29 at M3, and 0.33 at M6 but was stabilized at 0.28 at M12. At M12, VA did not significantly differ between MT and SD groups (0.27 vs. 0.32, p = 0.624). However, multivariate analysis revealed a significantly greater VA gain in the SD group (p = 0.025), despite more severe baseline characteristics. SMH thickness was significantly associated with a poorer VA (p=0.02). Conclusion Surgical displacement may offer greater visual improvement in cases of large and thick SMH. Maximum SMH thickness appears to be a key prognostic factor. Treatment decisions should consider initial hemorrhage severity.","PeriodicalId":19595,"journal":{"name":"Ophthalmologica","volume":" ","pages":"1-15"},"PeriodicalIF":1.9,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145058512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients were allocated chronologically into two groups: those operated on prior to February 2020 formed the standard positioning group (n = 23), and those treated thereafter composed the early positioning group (n = 20). In the early intraoperative positioning group, the patient's head was turned nasally immediately after the air-fluid exchange to stabilize the IF. In contrast, the standard group followed conventional postoperative prone positioning. The primary outcome was complete macular hole closure, assessed using optical coherence tomography. Secondary outcomes included IF stability, retinal layer integrity, and the need for additional postoperative surgical interventions.Results: At postoperative month 3, anatomical closure was achieved in all patients (100%) in the early positioning group, compared to 85% in the standard group (p = 0.05). Flap dislocation occurred in 15% of patients in the standard group, while none was observed in the early group (p = 0.05).

Data were collected before surgery and during the 12-month postoperative period. OCTA analysis focused on radial peripapillary capillary (RPC) vessel density (VD), superficial and deep capillary plexus (SCP and DCP, respectively). Functional and OCT structural outcomes, including best-corrected visual acuity (BCVA) and macular thickness, were also recorded.Results: Multivariate linear regression analysis revealed that higher preoperative RPC VD, lower SCP VD, and lower BCVA were predictors of postoperative BCVA improvement (p < 0.001, p = 0.047, and p < 0.001, respectively). Throughout the follow-up period, there was an observed increase in intradisc RPC VD, whole-disc VD, and parafoveal DCP VD (all p < 0.001). BCVA and central macular thickness demonstrated significant improvement (p < 0.001) within the first month following vitrectomy, which then stabilized from the third month onward.Conclusions: Preoperative microvascular measurements in iERM patients can forecast postoperative BCVA. OCTA findings reveal that both increased RPC density and reduced SCP density at baseline could serve as predictors of better visual outcomes after surgery. Enhanced RPC density may reflect a healthier optic nerve with greater potential for visual recovery, while a less dense SCP could indicate less iERM contraction, both contributing to more favorable postoperative visual results.","PeriodicalId":19595,"journal":{"name":"Ophthalmologica","volume":" ","pages":"54-66"},"PeriodicalIF":2.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142716757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to examine the correlation between metamorphopsia and foveal microstructure before and after macular surgery in a cohort of patients with advanced ERM.Methods: The severity of metamorphopsia was quantified using M-CHARTS, and foveal microstructure was evaluated via two optical coherence tomography (OCT) measures: central foveal thickness and ectopic inner foveal layer (EIFL). Assessments were performed pre- and post-surgery with an average follow-up of 1 year. Correlations between morphological and functional parameters pre- and post-surgery were explored by means of regression analysis.Results: Sixty eyes of 57 patients diagnosed with advanced ERM and surgically treated were included in the study. Our findings showed a significant correlation between postoperative metamorphopsia and both pre- (R2 = 0.431) and postoperative (R2 = 0.300) EIFL thickness.
