Glaucoma
2. What will happen to my sight?
Chronic Simple Glaucoma
A particularly insidious condition; there are rarely any obvious
symptoms such as pain or poor eyesight. However damage is still
being done.
The most obvious effect on sight is usually a reduced
visual field. This will often start with a small arc of blank vision
slightly off centre when the eyes are in the primary gaze position,
looking straight ahead. If left untreated the area of blank vision
spreads over the remaining visual field.
Commonly the central field of vision is not affected
until the end stage of the condition, leading to tunnel vision.
Acute (or Closed Angle) Glaucoma
Fortunately there are more obvious symptoms with acute glaucoma.
There will be severe pain in the affected eye associated
with redness, a drop in vision and occasionally total black out
of vision.
A commonly described symptom of early acute glaucoma
is rainbow coloured halos around bright lights, especially when
the eye has been functioning in low light conditions.
It is possible that mild forms of the symptoms will
precede the onset of the condition and should be treated as warnings
of the development of the acute condition.
