Suprachoroidal and Subretinal Injections of AAV Using Transscleral Microneedles for Retinal Gene Delivery in Nonhuman Primates. [PDF]

open access: yes, 2020
Retinal gene therapy using adeno-associated viruses (AAVs) is constrained by the mode of viral vector delivery. Intravitreal AAV injections are impeded by the internal limiting membrane barrier, while subretinal injections require invasive surgery and ...

A Micromechanical Parylene Spiral-Tube Sensor and Its Applications of Unpowered Environmental Pressure/Temperature Sensing [PDF]

open access: yes, 2007
A multi-function micromechanical pressure/temperature sensor incorporating a microfabricated parylene spiral tube is presented. Its visible responses in expression of in situ rotational tube deformation enable unpowered sensing directly from optical ...

Surgical management of glaucoma secondary to idiopathic elevated episcleral venous pressure

open access: yesOman Journal of Ophthalmology, 2015
Idiopathic elevated episcleral venous pressure is characterized by dilated episcleral veins and open angle glaucoma. Trabeculectomies in these eyes are often complicated by uveal effusions (intraoperative or postoperative) at nonhypotonous pressures.

Microrobotic Catheterization of the Ophthalmic Artery for Targeted Treatment of Retinoblastoma

open access: yesAdvanced Intelligent Systems, EarlyView.
A microrobotic platform is presented that allows teleoperated and autonomous navigation of flow‐driven magnetic microcatheters, MagFlow, into the ophthalmic artery for superselective intra‐arterial infusion of chemotherapy to treat retinoblastoma. Extensive benchtop validations with patient‐derived biomimetic phantoms under optical and fluoroscopic ...

In vivo imaging of structural, metabolic and functional brain changes in glaucoma

open access: yesNeural Regeneration Research, 2019
Glaucoma, the world’s leading cause of irreversible blindness, is a condition for which elevated intraocular pressure is currently the only modifiable risk factor. However, the disorder can continue to progress even at reduced intraocular pressure.

Time‐course characterization of intraocular pressure in murine steroid‐induced ocular hypertension: Effects of route, schedule, and concentration

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Steroid‐induced ocular hypertension is a useful mouse model for glaucoma, but published work rarely quantifies how route, dose, and schedule shape the intraocular pressure (IOP) time‐course—hindering reproducibility and forcing labs to pilot protocols.

CXCR3 antagonism of SDF-1(5-67) restores trabecular function and prevents retinal neurodegeneration in a rat model of ocular hypertension. [PDF]

open access: yesPLoS ONE, 2012
Glaucoma, the most common cause of irreversible blindness, is a neuropathy commonly initiated by pathological ocular hypertension due to unknown mechanisms of trabecular meshwork degeneration.
