We describe a novel technique using surgical data from the vitrectomy machine to differentiate between vitreous and balanced salt solution (BSS) in real time.Methods: Vitrectomy was performed in ex vivo porcine eyes across a range of vacuum levels and across available vitrectors on the Alcon Constellation. These measurements were repeated after vitrectomy in BSS. All surgeries were recorded and masked reviewers extracted the flow rates for each data point.Results: BSS flow rates were significantly higher (P<0.05) than vitreous flow rates except for 27-gauge at 20,000 cpm and 200 mmHg vacuum (P=0.093). As expected, higher cut rates, gauge, and vacuum corresponded to a higher flow rate. This allows clear differentiation between vitreous and BSS using flow rates as a guide.Conclusions: Inflow rate is a dynamic measurement through the Alcon Constellation System that can give immediate feedback to the surgeon on the substrate they are removing, improving surgical efficiency.","PeriodicalId":54486,"journal":{"name":"Retina-The Journal of Retinal and Vitreous Diseases","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143598181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous errors, inaccuracies, and poor methodology in the Kalaw et al. manuscript fail to support the claim that HBOT does not offer significant benefit in visual acuity among central retinal artery occlusion patients.

Demographic data, clinical characteristics, and OCT findings were analyzed, focusing on the presence of ME. Propensity score matching was performed to control for confounding variables, and multivariable logistic regression identified predictive factors for ME development.Results: A total of 114 eyes of 112 patients was included. ME developed in 64 out of 114 eyes (56.1%) during SO tamponade. The mean duration of SO tamponade was significantly longer in the ME group (665 days, SD 580) compared to the non-ME group (239 days, SD 196) (p<0.0001). PVR was present in 74 eyes (71.4%) in the RRD group. Additionally, 49% of eyes that did not develop ME during SO tamponade experienced ME after SO removal, with an average CMT increase of 39 μm (SD 9). Multivariable logistic regression analysis identified retinectomy (62% in the ME group vs. 29% in the non-ME group, p=0.0013) and longer duration of SO tamponade (p<0.0001) was associated with ME.Conclusions: This study demonstrates a high incidence of ME in eyes with SO tamponade. Prolonged SO tamponade and retinectomy were significant predictors of ME development. These findings emphasize the importance of careful monitoring and timely SO removal to minimize ME-related complications.","PeriodicalId":54486,"journal":{"name":"Retina-The Journal of Retinal and Vitreous Diseases","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143607136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The IR of BSS and air was measured at different intraocular pressures.Results: The AR increased in proportion to the increase in the aspiration pressure, and it was positively correlated with the cross-sectional area of the soft tips and negatively with the total length of the soft tips. The IR of BSS and air increased in proportion to the increase in the intraocular pressures settings.
