Neovascular Glaucoma
نویسنده
چکیده
Neovascular glaucoma (NVG) is an intractable sight-threatening disease which is extremely difficult to manage and can lead to permanent visual loss. It occurs as a result of iris neovascularization also known as rubeosis iridis. Once the condition develops, early diagnosis and management is essential to minimize visual loss, thus better understanding of the causes and pathogenesis is essential. The objective of this chapter is to discuss the causes, pathogenesis and management options of NVG.

The Ahmed glaucoma valve in neovascular glaucoma (An AOS Thesis).
PURPOSE To evaluate the results of Ahmed glaucoma valve surgery in neovascular glaucoma and control patients. METHODS In this retrospective comparative study, we reviewed 76 eyes of 76 patients, comparing the surgical outcomes in control patients (N=38) to matched neovascular glaucoma patients (N=38). Success was defined as intraocular pressure (IOP) > or =6 mm Hg and < or =21 mm Hg, without ...

Neovascular glaucoma is a challenging disease in its pathogenesis and treatment. Ischemic retinopathies can lead to neovascular glaucoma due to newly formed vessels on the iris surface and anterior chamber angle. Eyes with neovascular glaucoma can exhibit high intraocular pressure, usually treated by retinal coagulation, cyclodestructive procedures, or drainage procedures. Based on experimental...

RATIONALE Neovascular secondary glaucoma is a condition characterized by increased intraocular pressure due to the neovascularization occurring at the iridocorneal angle and iris, the most common complication of end-stage ischemic retina. The early diagnosis and treatment of this disease are important, because the functional prognosis is reserved. OBJECTIVE Knowing and understanding the etiol...
متن کاملHuman ciliary epithelium as a source of synthesis and secretion of vascular endothelial growth factor in neovascular glaucoma.
IMPORTANCE Retinal ischemia-induced upregulation of vascular endothelial growth factor (VEGF) leads to endothelial proliferation of the anterior segment, resulting in neovascular glaucoma. OBJECTIVE To investigate the ciliary epithelium as a possible source of VEGF in human eyes enucleated for intractable neovascular glaucoma. DESIGN, SETTING, AND PARTICIPANTS In this proof-of-concept, labo...
متن کاملAngioid streaks - a rare cause of neovascular glaucoma. Case report.
Rationale. Neovascular glaucoma is the type of glaucoma most refractory to treatment. The most frequent causes are those associated with retinal hypoxia, such as proliferative diabetic retinopathy, central retinal vein occlusion, branch retinal vein occlusion, central retinal arterial occlusion, ischemic ocular syndrome etc. Rare causes of neovascular glaucoma are multiple and are due to VEGF s...

Neovascular glaucoma is a secondary glaucoma with grave prognosis which follows ischemic retinal disorders in the majority of cases. Mediators that induce new vessel formation such as the vascular endothelial growth factor-A seem to play a key role in the pathophysiology of this condition. Herein, we report 2 cases with neovascular glaucoma secondary to ischemic central retinal vein occlusion w...
