Glaucoma causes progressive and permanent vision loss due to a buildup of fluid pressure in the eyeball. The disease presents itself in two common forms—primary open-angle glaucoma and angle-closure glaucoma. Unfortunately, both have their own unique and subtle set of symptoms, in which the unaffected eye counterbalances the vision loss in the affected eye.
Primary open-angle glaucoma, the most common type, begins at the peripheral working inward to incapacitate central vision, and leading to tunnel vision. While acute angle-closure glaucoma (also called chronic angle-closure or narrow-angle glaucoma) causes blurred vision with halo effects around eyes. Both types cause the irreversible and gradual damage of the optic nerve (the mechanism that sends visual information from retina to brain). The slow decline of sight often means the condition isn’t diagnosed until the advanced stage.
You can prevent glaucoma with regular optical exams (with a visual field test) and also by remaining watchful of these eight subtle warning signs…
The onset of sudden eye pain and headaches behind the eyes and brow are primary signs of late stage acute angle-closure glaucoma. The term “acute” refers to the sudden and irreversible damage to the optic nerve. If you experience eye pain, seek treatment immediately to prevent more severe vision loss and even blindness.
