, caused by a lack of blood nutrition. The blood flow to the optic nerve connects the back of the eye to the brain. Some people want to know how they can prevent the development of glaucoma. Actually there is no scientific answer. Doctors often recommend taking certain drugs and nutritional agents to improve optic nerve nutrition. Smoking, alcohol abuse, unhealthy diet and obesity should be avoided.
Glaucoma can be detected at very early stages through a detailed optic nerve analysis using a test which measures nerve fiber thickness. The test can be done within a few seconds. This test is quite important in diagnosing glaucoma, because there are no clear signs of common glaucoma. Cataract and glaucoma are independent that glaucoma neither affect the result of cataract surgery nor can benefit from it.
Normal eye pressure is between 12 and 21mm Hg. High eye pressure does not lead to glaucoma at 100%, but it should be closely monitored. Those people with only high eye pressure are usually referred as ocular hypertensives.
Treatments for glaucoma include some medications, which may cause systemic side effects. Most good anti-glaucoma medications are effective in controlling eye pressure at minimal dosages. However, some of these medications get absorbed into the blood stream and impact other organs. Patients should be clear aware of potentially harmful side effects.
