When informed of the possibility of glaucoma, most people have the same reaction: But I have no symptoms of glaucoma. This is precisely why the diagnosis and management of glaucoma continues to remain a problem despite all of the recent technological advances. Glaucoma has no symptoms in the initial stages. In fact, it is only in the later stages that you will actually experience any discomfort.
This article will discuss the symptoms of glaucoma, and their relative absence in most variants of glaucoma. It is however important to remember that even though the disease has no symptoms, its progress is insidious and ongoing. So, you must follow your doctors instructions about investigations, treatment and follow up even though you have no symptoms.
In fact, very often, glaucoma therapy will give you symptoms due to side effects of the medication, when you had none. It is important that you discuss these, and any visual disturbances with your doctor.
Symptoms of Adult Onset Glaucoma
Primary Open Angle Glaucoma
Vision loss due to glaucoma is slow and insidious. Which means that you will not notice in decrease in vision until the very late stages.
