A model for designing intraocular pressure-regulating glaucoma implants.

PLoS ONE, 2022
Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for vision. The key risk factor for the development and progression of this disease is increased intraocular pressure (IOP).

Hypotonous malignant glaucoma following glaucoma drainage device implantation

Indian Journal of Ophthalmology - Case Reports, 2021
Malignant glaucoma also known as “aqueous misdirection” is a frightening complication post glaucoma surgery. The usual presentation is with high intraocular pressure with flat anterior chamber both centrally and peripherally. The management option includes pharmacotherapy, laser and pars plana vitrectomy(PPV).

Biocompatible Magnetopyroelectric Composite Films for Cell Stimulation

Advanced Science, EarlyView.
Magnetopyroelectric films couple Fe3O4 nanoparticles with pyroelectric P(VDF‐TrFE) to turn alternating magnetic fields into controlled heat and pyroelectric currents. This heavy‐metal free platform safely boosts neural progenitor cells differentiation via synergistic thermal and pyroelectrical cues, engages AKT and calcium pathways, and opens practical

Risk factors for Baerveldt glaucoma drainage implantation for uveitic glaucoma

Scientific Reports, 2023
AbstractUveitic glaucoma (UG) is sometimes intractable, including intricate interaction between intraocular pressure (IOP) elevation associated with inflammation and side effects of steroids. Based on the Tube Versus Trabeculectomy study in refractory glaucoma results in 2012, tube shunt surgeries have been performed for UG, but few reports have ...
