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.
Parafoveal flow and vessel density (VD) are significantly reduced in individuals with early cognitive impairment and may serve as early biomarkers for Alzheimer’s disease (AD), according to a recent study.
High-dose cyclosporine A (CsA) cationic emulsion (CE) is well tolerated and effective in improving keratitis, symptoms and quality of life (QOL) in patients with severe vernal keratoconjunctivitis (VKC), according to a phase III study.
Presenting and best-corrected bilateral visual impairment (VI) and blindness are uncommon among Singaporeans, according to a new study. Important risk factors include the Malay ethnicity and advanced age and cataracts.
