Diagnosis of Glaucoma
Tests for Glaucoma Diagnosis
Diagnostic tests for glaucoma are very important. The optometrist may conduct various tests:
-
Measuring eye pressure
-
Examining the optic nerve
-
Evaluating visual fields
Measuring eye pressure, also known as intraocular pressure, is essential. Elevated pressure can indicate potential damage to the optic nerve. Visual field testing helps detect areas of vision loss, which can show glaucoma progression. These tests are valuable for identifying glaucoma early to prevent vision loss.
Assessing the drainage angle in the eye is also crucial for diagnosing angle-closure glaucoma. Regular eye exams with an eye doctor or optometrist are important, especially for individuals over 60 or with a family history of glaucoma, to detect the condition early.
Steps to Confirm Glaucoma Diagnosis
Confirming a glaucoma diagnosis involves specific tests by the eye doctor. These tests include:
-
Measuring eye pressure to check for elevated intraocular pressure.

Laser Therapy for Glaucoma
Laser therapy is used to treat glaucoma by managing intraocular pressure.
When eye drops or medications are ineffective, an optometrist might suggest laser treatment.
The treatment involves using a focused beam of light to help open clogged drainage canals in the eye or create a small hole in the iris.
This helps improve fluid outflow and reduces intraocular pressure.
The procedure is minimally invasive and typically done on an outpatient basis.
While laser therapy doesn’t cure glaucoma, it can slow down optic nerve damage and prevent further vision loss.
Patients should talk to their eye doctor about the risks and benefits of laser treatment to decide the best approach for their condition.
Surgical Procedures for Glaucoma
Surgical procedures can help with glaucoma when medications or laser therapy are not enough.
These surgeries aim to lower eye pressure by improving how the eye drains fluid.
One common surgery is trabeculectomy, where a new drainage channel is made to reduce pressure.
Trabeculoplasty is another option, using a laser to open blocked drainage canals.
Alternatively, tube shunt implantation involves placing a small tube in the eye for better fluid drainage.
Surgical treatments for glaucoma are more invasive than medications or laser therapy.
They are usually only used when other treatments haven’t worked.
While surgeries can effectively lower eye pressure and protect the optic nerve, they can also have side effects or complications.
Both the eye doctor and patient should carefully think about the risks and benefits.
Complications of Glaucoma
Glaucoma, if untreated or poorly managed, can lead to severe complications like irreversible vision loss. The increased eye pressure in glaucoma can damage the optic nerve, potentially causing blindness. Complications such as open-angle and angle-closure glaucoma can progress silently, resulting in gradual vision loss or sudden symptoms like eye pain and nausea, impacting daily life.
Risk factors like age, family history, ethnicity, and conditions like diabetes can increase the chances of glaucoma complications. Regular eye exams are important for early detection and monitoring by an eye specialist to prevent complications and preserve vision. Treatments such as eye drops, laser procedures, or surgeries can help manage glaucoma and prevent further optic nerve damage.
