Abstract

fetched live from OpenAlex

INTRODUCTION: Macular telangiectasia (MacTel) is a rare retinal condition that can cause vision loss, and anti-vascular endothelial growth factor (anti-VEGF) agents have emerged as a potential treatment. This study aimed to evaluate the clinical outcomes of anti-VEGF therapy in patients with MacTel. METHODS: A systematic literature search on Ovid MEDLINE, Embase, and Cochrane Library was performed from inception to June 2024 for comparative studies on anti-VEGF agents in MacTel. The primary outcome was the change in best-corrected visual acuity (BCVA). Secondary outcomes were central macular thickness (CMT), central choroidal thickness (CCT), and fluorescein angiography (FA) leakage. RESULTS: Ten studies on 377 eyes of 239 patients followed up over 23.4 ± 8.3 months were included. Mean (SD) BCVA changed from 0.42 (0.39) to 0.35 (0.18) over 23.4 (8.3) months of follow-up in non-proliferative MacTel. Mean BCVA changed from 0.66 (0.43) to 0.52 (0.34) at final follow-up in eyes with choroidal neovascularization (CNV). Five studies reported improved visual acuity, one showed improved FA leakage without visual acuity benefit, and four found no functional benefit. In non-proliferative MacTel, four studies showed no functional improvement, two reported significant functional and morphological improvements, and one suggested potential benefits in improving BCVA. In proliferative MacTel, two studies demonstrated improvement in both anatomical and functional outcomes, while one indicated that anti-VEGF treatment might produce improved results. In non-proliferative MacTel, mean CMT changed from 201 (32) µm to 199 (29) µm. CMT in patients with CNV decreased from an initial value of 328.23 (161.16) µm to 267.44 (118.56) µm at the final follow-up. CCT in proliferative MacTel eyes decreased from 272.37 (52.65) µm and 247.40 (48.80) µm on anti-VEGF therapy. Overall, FA leakage outcomes were improved on ranibizumab therapy. No study documented any significant adverse effects with treatment. CONCLUSION: Anti-VEGF agents may be associated with favorable anatomical and functional outcomes, particularly in proliferative MacTel; however, future large-scale clinical trials are warranted.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
