Primary open-angle glaucoma (POAG) is a chronic, progressive, usually bilateral disease of the eye with an insidious onset.
It is most often characterized by optic nerve damage, defects in the retinal fiber layer and subsequent visual field loss in the absence of underlying ocular disease or congenital abnormalities.
It is generally asymptomatic until it has caused a significant loss of visual field.
Occasionally, patients with very high intraocular pressure may complain of nonspecific headache, discomfort, intermittent blurring of vision or even halos caused by corneal edema.
The baseline inferior subfield retinal thickness may predict the frequency of treatment for diabetic macular oedema (DME) during the first year in eyes administered pro re nata (PRN) intravitreal ranibizumab (IVR) injections, a new study shows.
