What causes glaucoma in the eye?

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.

Can glaucoma go away?

Glaucoma cannot be cured, but you can stop it from progressing. It usually develops slowly and can take 15 years for untreated early-onset glaucoma to develop into blindness. However, if the pressure in the eye is high, the disease is likely to develop more rapidly.

What are the signs of high eye pressure?

What are the symptoms of glaucoma?

  • Eye pain or pressure.
  • Headaches.
  • Rainbow-colored halos around lights.
  • Low vision, blurred vision, narrowed vision (tunnel vision) or blind spots.
  • Nausea and vomiting.
  • Red eyes.

How can I get rid of glaucoma naturally?

Natural prevention of glaucoma

  1. Maintain a healthy weight. Both high and low body mass indexes (BMIs) can increase the risk of glaucoma.
  2. Avoid smoking.
  3. Consider meditation. Stress appears to increase a person’s risk of high IOP.
  4. Practice good dental hygiene and see a dentist on a regular basis.
  5. Get screened for glaucoma.

What is consensual pupillary response?

The consensual pupillary response is the constriction that normally occurs in a pupil when light is shown into the opposite eye.6 Because of this response, the trauma nurse should wait for several sec- onds before assessing pupillary light reflex in the second eye, as that pupil may be temporarily constricted.

What is a pupillary abnormality?

The pupil has tight neurological control and abnormalities of this control correlate with underlying diagnoses. The exam and those diagnoses are covered here. There are a handful of pupillary abnormalities that every clinician should know. Here we review the basic physiology then describe these abnormal pupillary responses and how to find them.

What is the significance of pupil size in unilateral optic nerve disease?

In patients with unilateral optic nerve disease, with one eye covered and other eye exposed to bright light, the pupil of affected eye settles at a larger diameter. This difference (in millimeters) in size of two pupils, is a measure of the difference in pupillomotor input between the two eyes.

What is a relative afferent pupillary defect?

Relative Afferent Pupillary Defect (RAPD, Marcus Gunn Pupil) An RAPD is a defect in the direct response. It is due to damage inoptic nerve or severe retinal disease. It is important to be able to differentiate whether a patient is complaining of decreased vision from an ocular problem such as cataract or from a defect of the optic nerve.
