Cataract Clinic - The UK's number 1 Clinic for Eye Surgery and Treatment Treatment  

The treatment of glaucoma is much better now than it was even 5 years ago. Most patients are treated only with drops. The drops work by lowering the pressure to the target pressure for that eye. The target pressure is the pressure below which the doctor believes no further significant damage will occur. It is different for different eyes. Your ophthalmologist will tell you what your target pressure is and whether your treatment has achieved it yet. When drops fail then surgery may have to be considered. The surgery involves passing a very fine fibre around the drainage canal and tying it so that the canal drains more effectively. This operation is called a canaloplasty.
Glaucoma is for life. Once you have been diagnosed as having glaucoma you will need to have the disease monitored for the rest of your life.

Monitoring your disease
There are three very important tests which are carried out, 1/ intraocular pressure (IOP) measurement, 2/ OCT examination which examines the parts of the retina and optic nerve which are damaged before the vision is affected and 3/ field of vision test. The IOP test is done by pressing a probe lightly on the eye to see how hard it is (just like a referee testing the ball at the beginning of a match). It is painless and completely safe for the eye. The probe in calibrated for each eye by measuring the thickness of the cornea. The OCT examination is done simply by asking the patient to look at a blue dot while a laser beam scans the eye for possible damage. It is harmless and painless. The field of vision test is done on a specialised machine where a white light is shone onto a bowl in front of the patient and the patient presses a switch each time they see the spot of light. In this way any blind spots are picked up and the machine can see if they are getting bigger. Typically these tests are carried out every nine or twelve months.
Summary

Most patients with glaucoma retain good vision indefinitely. Modern treatment is easy and very effective. Only a small number of patients lose significant vision.
