Diseases » Glucoma




Glaucoma is defined as an optic neuropathy. Glaucoma is a group of diseases that is characterized by elevated intraocular pressure (IOP). The fluid pressure inside the eye slowly increases and causing damage to the optic nerve, it leads blindness. The optic nerve is a bunch of nerve fiber that connects the retina and brain.

Types:

Open-angle glaucoma: This is the common type of glaucoma seen most widely. This happens because the drainage canal in the eye gets clogged. The intraocular pressure (IOP) increases since the fluid is not drained out of the eye. If treated in early stage this can be cured fully.

Acute Angle Closure: Acute angle closure is caused due to abnormality found in the space between iris and cornea. This space becomes narrow reducing the space for the aqueous movements. The blockage in flow of aqueous leads to increased pressure inside leading to a sudden angle closure attack. Symptoms include severe eye pain along with nausea, blurred vision, rainbows around lights and a red eye.

Secondary Glaucoma: Secondary glaucoma is a disease that occurs because of certain disease in eye that can include inflammation, trauma, previous surgery, diabetes, tumor and certain medications. 

Congenital: This is seen in infants. Surgery may be required. Children are born with a in the eye that slows the normal drainage of fluid. The symptoms include cloudy eyes, sensitivity to light and excessive tears. On successful surgery there is a great chance of getting good vision.
