A review on glaucoma: A silent killer of vision

Glaucoma is a neurodegenerative disorder that affects the optic nerve and the inner layers of the retina. Increased intraocular pressure is a major risk factor in the disease. Chronic elevation of intraocular pressure specifically induces the death of retinal ganglion cells. Recent advances have seen a surge of new ideas and technologies to aid in the detection, treatment and further understanding of glaucoma. These technologies and advances are discussed to provide information on risk-factors, diagnosis and treatment. This study reviews current concepts in the goals of glaucoma therapy, and options for the management of glaucoma.
