What is Glaucoma?

Glaucoma is a group of eye diseases that can damage the optic nerve, resulting in vision loss and blindness. Glaucoma is commonly described as a build-up of pressure in the eye. Although there is no cure, glaucoma can be effectively managed through treatment if it is caught early during routine eye exams.

Early detection reduces the chance of vision loss

Risk factors for glaucoma

  • Aging
  • Family history
  • High eye pressure
  • Race (African Americans, Hispanics and Asians are a higher risk)
  • Long-terms steroid use
  • Eye Injury
  • Thin corneas

Glaucoma evaluation:

  • Measuring eye pressure
  • Inspecting eye’s drainage
  • Examining optic nerve damage
  • Testing peripheral (side) vision
  • Taking an image or computer measurement of the optic nerve
  • Measuring the thickness of the cornea

Types of Glaucoma

Open-Angle Glaucoma: This is the most common type of glaucoma. It occurs when fluid drains too slowly through the eye, causing pressure to build up over time.

Narrow-Angle Glaucoma: This type of glaucoma can be a medical emergency. Closed-angle glaucoma occurs when the eye’s drainage system is completely blocked, leading to a rapid rise in pressure. Symptoms include a headache after being in a dark room, blurred vision at night, colored haloes around light, severe eye pain, nausea, and vomiting.

Normal-Tension Glaucoma: As the name suggests, this type of glaucoma occurs despite normal eye pressure levels. Although the etiology is not completed understood studies suggests that Japanese descendants and people with vascular disorders are most at risk for developing this form of glaucoma.

Glaucoma Treatments offered at Precision Eye Care

Prescribed Eye Drops

Taken regularly, as directed by your eye care provider, these eyedrops lower eye pressure. Some causes the eye to make less fluid, others lower pressure by helping fluid drain from the eye.

Laser Surgery

Selective Laser Trabeculoplasty (SLT) reduces the need to use eye drops to lower the eye pressure. SLT is an outpatient procedure, and patients can resume normal activities after treatment.

Laser Iridotomy is a laser procedure that entails creating a small hole in the iris, allowing fluid to drain and preventing pressure build up.


Minimally-Invasive Glaucoma Surgery

Minimally-Invasive Glaucoma Surgery (MIGS) is typically done in combination with cataract surgery. During MIGS, a microscopic device is placed into the eye to lower and control intraocular pressure. Not all the patients with glaucoma are candidates for MIGS.


Key benefits of MIGS:

  • This procedure is likely to reduce your need for eye drops .
  • Reduces the chances of progression of glaucoma and loss of vision associated with the disease
