The visual field is the space covered by the vision of the eye when it is static and viewing a fixed point. Typically, the perimeter of the visual field and sensitivity within the different areas of the perimeter are assessed.
What is the width of our visual field?
The width of our horizontal visual field is 200º, whereas the vertical is 130º in normal conditions.
Why does eye pressure increase?
An increase in eye pressure is a result of several factors which can be summarised as mechanisms that prevent intraocular fluid (aqueous humour) from being removed properly through the normal channel. This can be mild and chronic—chronic glaucoma—or sudden, due to other processes. The ophthalmologist has to examine the patient urgently, especially in the event of acute forms.
