Symptoms of a disc protrusion usually become prevalent when the protrusion begins to irritate or put pressure on a nerve, which results in the pain that most patients feel. 1  Many symptoms depend on where the affected disc is located and the severity of the protrusion.
Glaucoma is the result of damage to the optic nerve. As this nerve gradually deteriorates, blind spots develop in your visual field. For reasons that doctors don't fully understand, this nerve damage is usually related to increased pressure in the eye.ngle-closure glaucoma. Angle-closure glaucoma, also called closed-angle glaucoma, occurs when the iris bulges forward to narrow or block the drainage angle formed by the cornea and iris. As a result, fluid can't circulate through the eye and pressure increases.
Glaucoma is one of the leading causes of blindness in the United States. It can occur at any age but is more common in older adults. The most common form of glaucoma has no warning signs. The effect is so gradual that you may not notice a change in vision until the condition is at an advanced stage. Vision loss due to glaucoma can't be recovered. So it's important to have regular eye exams that include measurements of your eye pressure.
