Common Eye Conditions
Glaucoma: What You Need To know
People over the age of 60 can suffer from various eye conditions. Among these, glaucoma is a disease that can potentially cause permanent vision loss or very severe sight impairment. A buildup of pressure on your eyes can lead to the erosion and deterioration of optic nerves inside your head. But that high pressure may not always be the cause.
As the optical nerves in your eye deteriorate, you experience the occurrence of dark or floating spots in your field of view. This is visual distortion. Studies confirm that the total number of glaucoma patients is over 80 million worldwide.

What is Glaucoma? – Causes, Symptoms, and Treatments
Below are the types of glaucoma eye diseases that are evidently the most common among patients.
- Normal-Tension Glaucoma (NTG)
- Angle-Closure Glaucoma
- Congenital Glaucoma
- Open-Angle Glaucoma
Symptoms are minute at the early stages of glaucoma. Nonetheless, as the disease progresses, symptoms grow more noticeable and vivid. Here are a few:
- Severe eye pain
- Red eyes
- Tenderness around eyes
- Blurry and wavy vision
- Rings around lights
- Rainbow color circles in vision
Glaucoma, at the early stages, is only detectable through annual eye exams with your professional optometrist.
As the damaged optical nerves inside your head deteriorate, blind spots and light circles start developing in your field of view. One cause is the intense pressure on your eye, which causes a buildup of fluid in the blood vessels. Eventually, this fluid leaks at the back of the eye.
Pressure builds up when fluids are unable to move through the eye. A common cause for eye diseases, such as glaucoma is heredity. Genes are a major reason for the development of eye diseases in many people.
Moreover, an eye injury might also cause excessive damage to the optical nerves. In the long-term, this can lead to glaucoma.
Glaucoma treatments ensure a healthy and consistent flow of fluids (including their drainage) throughout the blood vessels at the back of your head. This relieves pressure on the optical nerves.
A few surgery options are available to relieve pressure from the optical nerves when medication isn’t effective.
- Drainage implant involves the insertion of a tiny silicon tube to help drain accumulated fluids
- Trabelculoplasty involves laser surgery to unclog the fluid canals for better drainage
- Filtering surgery involves the opening of several new channels to allow better drainage of fluids from the eye
Most people opt for eye drops as the method to ensure healthy fluid drainage and flow. The drops can help maintain fluid production by increasing or decreasing fluid drainage in the eyes.
