Glaucoma is a disease that damages the optic nerve i.e. the nerve for vision, due to increased eye pressure or intraocular pressure. It is not just one eye disease, but a group of eye conditions which results in optic nerve damage, which causes loss of vision.
Glaucoma is one of the leading causes of blindness and often referred to as “silent thief of sight” because it damages your eye vision so moderately that you won’t be able to notice any vision loss until it reaches its advanced stage. The primary open-angle glaucoma, the most common type of glaucoma, has no noticeable symptoms except gradual vision loss.
Glaucoma is detected through a comprehensive dilated eye exam which includes the following:
- Pachymetry – it is the process of measuring the thickness of the cornea. The eye care professional applies a numbing drop to the patient’s eye and uses pachymeter, the device which helps in measuring the thickness of the patient’s cornea.
- Tonometry – tonometry is a quick and simple test that checks the pressure inside your eyes by using an instrument called tonometer. Drops may be applied to the patient’s eye to make that area numb, for this test.
- Visual field test – this test helps in determining the dysfunction of the patient’s side vision or peripheral, which is a sign of glaucoma. in this process, drops are placed in the patient’s eyes to widen or dilate the pupils. The eye care professional uses a special magnifying lens to examine the patient’s retina and optic nerve for signs of damage and other eye problems. After this test, the patient may experience blurred vision for several hours.
