Many forms of eye disease do not exhibit any symptoms in their early stages, so you may not even realize something is wrong until permanent damage has been done to your vision. Your best defense against eye disease is to book regular eye exams.
Common Types of Eye Diseases
• Age-Related Macular Degeneration (AMD)
Age-related macular degeneration (AMD) is the most common eye disease affecting patients over 55.
AMD deteriorates your macula, the part of your retina responsible for your central vision. When your macula is damaged, it can affect your ability to read, drive, or recognize faces.
There are 2 common types of AMD:
Dry AMD
occurs when deposits of druses form underneath your macula, deteriorating your macula and damaging your vision.
Wet AMD
occurs when fragile blood vessels from underneath your macula. When these vessels break, they leak fluids underneath your macula that damage it, leading to sudden vision loss. Wet AMD is also considered a medical emergency that requires immediate attention.
• Glaucoma
What is Glaucoma?
Glaucoma is a collection of eye diseases that damage the optic nerve. The risk of developing these diseases can increase if you have diabetes or if your family has a history with it.
What Causes Glaucoma?
Most of the time, glaucoma is caused by raised intraocular pressure but can develop even when your eye’s internal pressure is within the normal range. The two most common forms are;
Open-angle glaucoma
Open-angle glaucoma occurs when the drainage canal between iris and cornea becomes clogged or partially blocked, slowly increasing your eye’s intraocular pressure, damaging the optic nerve, and causing vision loss.
Angle-closure glaucoma
occurs when the angle between the iris and cornea closes completely, blocking fluids from leaving the eye. This type of glaucoma is considered a medical emergency because of how fast it can permanently damage your vision.
Symptoms of Glaucoma
If you have open-angle glaucoma, you can experience blind spots in your peripheral or central vision. In the advanced stages, you can experience tunnel vision.
If you have angle-closure glaucoma, you can experience headaches, eye pain, nausea, eye redness, and even blurred vision. All of these can develop quite quickly, so please make sure you contact medical assistance if any or all of these symptoms are developing.
Glaucoma Treatments
The best way to prevent the development of glaucoma as you grow older is to make sure you attend regular eye exams. Like many diseases, your eye care team will have a better opportunity to treat your symptoms if they are able to detect the disease early.
Depending on the severity of your glaucoma, your optometrist can prescribe eye drops to lower eye pressure, or can recommend lifestyle changes.
