Schlemm's Canal Surgery in Juvenile-Onset Open-Angle Glaucoma: A Narrative Review.

Background: Juvenile-onset open-angle glaucoma (JOAG) is a rare and refractory form of glaucoma, primarily characterized by structural abnormalities in the trabecular meshwork and Schlemm's canal. These abnormalities disrupt aqueous humor outflow, resulting in elevated intraocular pressure and progressive glaucomatous damage. Pharmacological and laser therapies are generally ineffective in managing JOAG.

Axial elongation in nonpathologic high myopia: Ocular structural changes and glaucoma diagnostic challenges.

Axial elongation continues in highly myopic adult eyes, even in the absence of pathologic changes such as posterior staphyloma or chorioretinal atrophy. This ongoing axial elongation leads to structural changes in the macular and peripapillary regions, including chorioretinal thinning, reduced vascular perfusion and optic disc tilting and rotation, among others. These alterations can affect the acquisition and interpretation of optical coherence tomography, optical coherence tomography angiography and fundus photographs, potentially introducing artifacts and diminishing the accuracy of glaucoma diagnosis in highly myopic eyes.

Gold saturable metasurface for building a wavelength-tunable optical spiking neuron.

Plasmonic resonant metasurfaces have found many applications in nonlinear optics, such as harmonic generation, all-optical modulation, saturable absorption, etc. A saturable absorber, as a key device for pulsing emission, plays an important role in building passively Q-switched or mode-locked fiber lasers. Recently, excitable fiber lasers have attracted much attention in the area of neuromorphic photonics.

Effect of intraocular pressure reduction on progressive high myopia (PHM study): study protocol of a randomised controlled trial.

Background: In adult patients with high myopia (HM), progressive axial elongation poses a significant risk for the development of subsequent ocular complications that may lead to visual impairment. Effective strategies to reduce or prevent further axial elongation in highly myopic adult patients have not been available so far. Recent studies suggested that medically lowering intraocular pressure (IOP) may reduce axial elongation.
