Both 3 × 3 mm and 6 × 6 mm scans were obtained on the same day. Two masked graders independently evaluated neovascular network area and presence of anastomoses.ResultsMean lesion areas were significantly larger in 6 × 6 mm scans compared to 3 × 3 mm scans (0.869 ± 0.868 mm² vs 0.699 ± 0.697 mm²; p = 0.005). However, analysis of anastomoses revealed superior detection with 3 × 3 mm scans, with 12 eyes (15.2%) showing anastomoses only in 3 × 3 mm scans compared to 4 eyes (5.1%) visible only in 6 × 6 mm scans (p = 0.021). Interobserver agreement was excellent for area measurements (ICC = 0.92).ConclusionsWhile 6 × 6 mm SS-OCTA scans demonstrate larger overall neovascular area measurements, the 3 × 3 mm scan pattern provides superior visualization of anastomoses and fine vascular details in pachychoroid-associated MNV. These findings suggest that 3 × 3 mm scans should be considered the preferred protocol for detailed evaluation of these lesions.","PeriodicalId":12000,"journal":{"name":"European Journal of Ophthalmology","volume":" ","pages":"11206721251382019"},"PeriodicalIF":1.4,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145250354","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}

A stratification model for identification of virtual pathway candidates was defined and implemented as follows: good virtual pathway candidates included those with posteriorly located lesions for adequate photographic capture and no more than two high-risk features. Risk factors, outlined by the TFSOM-DIM acronym, included thickness >2 mm, presence of subretinal fluid, visual acuity 20/50 or worse, presence of orange pigment, low internal reflectivity, and basal diameter >5 mm. Of posteriorly located lesions, those with 0-2 risk factors were defined as good virtual pathway candidates, 3 risk factors as acceptable in select cases, and 4 or more as poor candidates.ResultsThere were 614 choroidal nevi in 586 patients diagnosed during the study period. Mean patient age at initial visit was 63.5 years old (median 66.1, range 5.8-94.8), with 59.4% female and 98.8% white.

This systematic review and meta-analysis (CRD42025637001) aim to compare the incidence of anterior vitrectomy in cataract surgeries performed by ophthalmology residents versus experienced surgeons and assess factors contributing to surgical complications.MethodsA systematic search was conducted across EMBASE, MEDLINE, CINAHL Plus, Web of Science, ClinicalTrials.gov, PQDT Global, ARVO and AAO for studies published after 2000 that reported on anterior vitrectomy incidence in cataract surgery. Eligible studies included randomized controlled trials and observational studies. Meta-analysis was performed using STATA v. 18.0.ResultsOut of 1,190 screened studies, five studies (four retrospective cohort, one prospective cohort) involving phacoemulsification, extracapsular cataract extraction (ECCE), and femtosecond laser-assisted cataract surgery (FLACS) were included, encompassing a total of 4,918 cataract surgeries, and 208 anterior vitrectomy (AV) cases. The random-effects meta-analysis demonstrated a significant AV incidence for residents (ES = 0.04, 95% CI: [0.01, 0.06]), while the incidence for experienced surgeons was not statistically significant (ES = 0.03, 95% CI: [-0.03, 0.09]). High heterogeneity was observed among the included studies (I² = 92.1% for residents and I² = 96.7% for surgeons).ConclusionResidents may have a higher incidence of AV, highlighting the potential benefits of structured surgical training, early exposure, and mentorship in reducing intraoperative complications.

HFA II (24-2, Swedish Interactive Threshold Algorithm) and Oculera (24-2, Oculera Interactive) tests were applied to all participants.

The difference between MDs of Oculera and HFA II was -0.56 dB. Wilcoxon signed-rank test showed a statistically significant difference in MD values between Oculera and HFA II (p < 0.001). However, there was a strong correlation between MDs (r = 0.932 and p < 0.001). With this, the results of the Bland-Altman analysis evaluating the agreement between the two tests showed that the differences between the MD measurements were not within the acceptable error range and that the results of the devices could not be used interchangeably.
