Understanding the spacing of placodes in the eye: A comparative study across age and species

The Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

A prospective randomised comparison of two different stenting sutures when using the Baerveldt 101–350 aqueous shunt – Lab transition to clinical process

Acta Ophthalmologica, EarlyView.
Abstract Purpose The Baerveldt glaucoma drainage implant (BGI 101–350) is one of the most effective treatment options for managing refractory glaucoma. To mitigate early hypotony in non‐valved implants, intraluminal occluding sutures (IOSs) are commonly used.

Longitudinal changes in bleb morphology following the PAUL Glaucoma Implant visualized using ultrasonography

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate bleb morphology longitudinally using sonography following glaucoma drainage device (GDD) surgery. Methods Prospective observational cohort study conducted from January 2022 to March 2024, with follow‐up up to 12 months postoperatively. Bleb morphology, including superior and inferior bleb height, transverse and longitudinal
