Callahan Glaucoma Comparison


Glaucoma is a condition where the eye does not withstand its own intraocular pressure very well. This results in the Optic Nerve slowly dying off. Unfortunately, the damage is irreversible, and it is therefore vital to have regular eye exams, especially if there is a family history of glaucoma.

If during a routine eye exam we suspect glaucoma, we will refer you to an ophthalmologist for further investigation. Treatment may include eye drops, laser surgery or a combination of both.

Diagnosing an Eye Disease

Glaucoma can affect people of all ages, but it is more common among the elderly. Glaucoma comes in a variety of types, each with its own set of symptoms or warning signals.

Most persons with glaucoma do not notice any changes in their vision until the disease has progressed to an advanced stage. The loss of eyesight caused by glaucoma cannot be reversed. This is why it is critical to detect Glaucoma early in order to avoid blindness. This is only one of the many reasons why senior eye care is so critical.

Optometrists recommend yearly eye exams for anyone over the age of 60. When glaucoma is identified early, the vision loss that usually follows can be avoided or at least reduced. Glaucoma patients typically require glaucoma therapy for the remainder of their lives. Glaucoma comes in several forms, including:

Open-angle glaucoma

Open-angle glaucoma occurs when the drainage system in the eye gets partially blocked. It is the most common type of glaucoma.

Angle-closure glaucoma

Angle-closure glaucoma occurs when the iris blocks the drainage path. This can also occur if the patient has a more narrow drainage system.

Normal-tension glaucoma

Normal-tension glaucoma occurs when the optic nerve sustains damage despite the patient having healthy eye pressure.

Pigmentary glaucoma

Pigmentary glaucoma occurs when pigment granules that part with the iris build up in the drainage system in the eyes.

Signs That Glaucoma Treatment Is Required

Open-angle glaucoma symptoms and signs differ according to the individual’s condition and the kind of glaucoma. Among the possible symptoms are the following:

  • Severe headaches
  • Blind spots in a person’s vision
  • Tunnel vision in the later stages

For the acute angle-closure variety, the symptoms include:

  • Vomiting and nausea
  • Halos appearing around light
  • Red eyes
  • Headaches
  • Blurred vision
