Genetic, Cellular and Ultrastructural Mechanisms in Retinal Detachment
Rhegmatogenous retinal detachment (RRD) is a blinding eye condition, usually requiring emergency surgical repair. The proximate cause is a retinal tear caused by posterior vitreous detachment (PVD), but most people with PVD do not develop RRD. Understanding the underlying processes may help to …

Design of a Precision Needle for Injection of Fluid into the Suprachoroidal Space of the Eye for the Treatment of Retinal Detachment
Rhegmatogenous retinal detachment (RRD) is a vision-threatening condition that affects 10 to 18 per 100,000 people in the United States annually [1]. The current standard for treatment is pars plana vitrectomy (PPV), which is an invasive and expensive surgical procedure that leaves patients unable …

Vascular Endothelial Growth Factor in the Aqueous Humor of Dogs With and Without Intraocular Disease
… intraocular disease processes, including tumors, retinal detachment and uveitic glaucoma. Pharmacotherapy inhibiting VEGF expression demonstrates promise for control of some of these ophthalmic conditions. We quantified and compared VEGF concentrations in canine aqueous humor samples from 13 dogs …

Mechanisms of p19Arf-Mediated Regulation of Perivascular Cell Biology During Mammalian Eye Development
… detrimental ocular defects including blindness, retinal detachment and lens opacity. It has been further demonstrated that p19Arf enacts a dual mechanism to inhibit the accumulation of the perivascular cells that occupy the vitreous space during development and lead to the clearing of these cells …
