Glaucoma is a group of diseases that can damage the eye's optic nerve. It is a leading cause of blindness. It usually happens when the fluid pressure inside the eyes slowly rises, damaging the optic nerve. Often there are no symptoms at first. Without treatment, people with glaucoma will slowly lose their peripheral, or side vision. They seem to be looking through a tunnel. Over time, straight-ahead vision may decrease until no vision remains. The most common type of glaucoma, primary open-angle glaucoma, has no noticeable signs or symptoms except gradual vision loss.
The exact cause of optic nerve damage from glaucoma is not fully understood, but involves mechanical compression and/or decreased blood flow of the optic nerve. Although high eye pressure sometimes leads to glaucoma, many people can also develop glaucoma with "normal" eye pressure.
The most common types of glaucoma - primary open-angle glaucoma and angle-closure glaucoma - have completely different symptoms.
Primary open-angle glaucoma signs and symptoms include:
- Gradual loss of peripheral vision, usually in both eyes
- Tunnel vision in the advanced stages
Acute angle-closure glaucoma signs and symptoms include:
- Eye pain
- Sudden onset of visual disturbance, often in low light
- Halos around lights
- Nausea and vomiting (accompanying the severe eye pain)
- Blurred vision
- Reddening of the eye
Both open-angle and angle-closure glaucoma can be primary or secondary conditions. They're called primary when the cause is unknown and secondary when the condition can be traced to a known cause, such as eye injury, medications, certain eye conditions, inflammation, tumor, advanced cataract or diabetes. In secondary glaucoma, the signs and symptoms can include those of the primary condition as well as typical glaucoma symptoms.
If left untreated, glaucoma will cause progressive vision loss, normally in these stages:
- Blind spots in your peripheral vision
- Tunnel vision
- Total blindness
Homoeopathy not only relieves symptoms of the patient but also prevents complications.
