By combining datasets from previous studies, we apply a mixed-effects modeling approach-which offers advantages over the statistical methods used in previous studies-to investigate the contributions of pattern update rate and number of unique frames to perceptual sensitivity. Our findings indicate that the number of unique frames is the most robust predictor of discrimination thresholds, supporting the idea that the visual system integrates global form information across multiple frames-a process consistent with spatiotemporal summation. In contrast, the pattern update rate showed a weaker, though statistically significant, effect. This suggests that faster updates help preserve temporal consistency between frames, facilitating global form extraction. These results align with previous observations on complex dynamic GPs, where discrimination thresholds decrease with more unique frames, suggesting that the summation of form signals across time plays a key role in form-motion perception. By adopting a mixed-effects modeling approach, our reanalysis provides new insights into the mechanisms underlying global form perception in dynamic GPs.</p>","PeriodicalId":36586,"journal":{"name":"Vision (Switzerland)","volume":"9 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12372061/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144972661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 5-Year Retrospective Study of Long-Term Effects.","authors":"Maria Vivas, José Charréu, Bruno Pombo, Tomás Costa, Ana Sofia Lopes, Fernando Trancoso Vaz, Maria João Santos, Isabel Prieto","doi":"10.3390/vision9030068","DOIUrl":"10.3390/vision9030068","url":null,"abstract":"<p><p>Combined trabeculectomy-phacoemulsification is known to provoke more inflammation and yield a poorer long-term efficacy than trabeculectomy alone.

We retrospectively analyzed 51 eyes from patients who underwent either Ahmed-Alone (n = 25) or PhacoAhmed (n = 26) surgery over a 5-year period. The primary outcomes included intraocular pressure (IOP), the use of IOP-lowering medications, and the need for further surgical intervention. Absolute success was defined as IOP reduction > 20% and IOP < 21 mmHg without medication; relative success allowed for continued pharmacologic therapy. Both groups showed a significant IOP reduction, with similar final mean IOP values (Ahmed-Alone: 14.02 ± 4.76 mmHg; PhacoAhmed: 13.89 ± 4.17 mmHg; <i>p</i> = 0.99) and comparable reductions in medication use (<i>p</i> = 0.52).

This behavioral interference has been shown to be elicited by the semantic rather than by the perceptual properties of a scene, as it resisted the application of low-pass spatial frequency filters. Some studies observed that the visual system can adapt to perceptual conditions; however, little is known concerning whether attentional capture by emotional stimuli can also be modulated by the sequential repetition of viewing conditions or of emotional content. In the present study, we asked participants to perform a parity task while viewing irrelevant natural scenes, which could be either emotional or neutral. These scenes could be either blurred (low-pass filter) or perceptually intact, and the order of presentation was balanced to study the effects of sequential repetition of perceptual conditions. The results indicate that affective modulation was most pronounced when the same viewing condition (either intact or blurred) was repeated, with faster responses when perceptual conditions were repeated for neutral distractors, but to a lesser extent for emotional ones. These data suggest that emotional interference in an attentional task can be modulated by serial sensitization in the processing of spatial frequencies.</p>","PeriodicalId":36586,"journal":{"name":"Vision (Switzerland)","volume":"9 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12372086/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144972611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
