Glaucoma results from raised intraocular pressure. The pressure usually builds up due to blockage in the drainage of the aqueous humor from the anterior chamber of the eyes.
In healthy eyes, this fluid constantly flows in and out of the eye. It drains back into the bloodstream at the same rate that it is produced to maintain the correct pressure.
5 Major Signs that Indicate Glaucoma
Halos Around Lights
Halos are bright circles that surround a light source, almost like headlights. Seeing halos around lights means that you are developing a serious eye disorder, it could be glaucoma or cataracts. Some patients report seeing halos around lights as a side effect of cataract surgery, LASIK surgery, or because of eyeglasses, they are wearing at the time.
Loss of Vision in One Eye
If you notice a loss of vision or develop a blind spot in your field of vision, it’s time to get tested for glaucoma. It is worth noting that glaucoma does cause a gradual loss of vision, so now is as good a time as any to get an eye checkup. This becomes even more important if you experience sudden blindness in one eye, at this point, it is an emergency.
If you indeed have glaucoma, then you’re left with a very short window of time for getting treatment to avoid permanent blindness. Temporary loss of vision is a symptom of a more serious underlying issue such as a stroke and doesn’t always indicate glaucoma.
Cloudy Looking Eyes
The cornea has a sheet of cells on the inside that pump watery fluid out of the cornea, keeping it clear. If the pressure rises a little too high, the fluid will be pushed into the cornea, making it cloudy and waterlogged. This is what leads to cloudy-looking eyes.
Cloudy eyes are easily detectable in a mirror and should be immediately checked in by a doctor. In many cases, cloudy eyes are caused due to cataracts which often affect older people. If you experience hazy eyes, it’s time to get a checkup.
Sensitivity to light
Younger people with raised eye pressure (IOP) show increased sensitivity to light. There may be several reasons for this. The clear window of the eye may be cloudy and waterlogged, which is uncomfortable. When the cornea isn’t completely clear it will cause light to bounce off the cornea irregularly, causing glare. While this doesn’t harm a person’s vision in the short term, it is an early sign of glaucoma.
Sever and Sudden Eye Pain
The most obvious sign of an acute attack of glaucoma is severe eye pain. This will often require emergency treatment because the pain is often unbearable. Such an attack will often cause redness of the eye, and nausea, with or without vomiting.
The symptoms of glaucoma often come on gradually, and your brain can fill in the gaps of changed vision. Most people experience no symptoms in the early stages of glaucoma and the only way to know if you have it is by having your eyes tested.
