Abstract

fetched live from OpenAlex

Non-penetrating deep sclerectomy (NPDS) is a non-perforating filtration procedure used for the surgical treatment of medically uncontrolled open angle glaucoma. This procedure was developed in an attempt to avoid many of the postoperative complications of trabeculectomy.1 The major advantage of NPDS is that it precludes the sudden hypotony that occurs after trabeculectomy by creating progressive filtration of aqueous humour from the anterior chamber to the subconjunctival space, without perforating the eye.2 Preservation of the thin trabeculo-Descemet’s membrane, however, is technically challenging, particularly before the surgeon gains experience with this procedure. Previous studies investigated the ability to use the femtosecond laser for photodisruption in the human sclera,3 4 and concluded that complete subsurface photodisruption can be accomplished in human sclera in vitro . Toyran et al. 5 in 2005 published their in-vitro study that tested the feasibility of using femtosecond laser pulses to fistulise the human trabecular meshwork and concluded that, with appropriate exposure time and pulse energy, femtosecond photodisruption can be employed to create partial …

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.
