What happens at a Visual field Test

A depiction of what you see in a field test. Square grid and dots
To check your field of vision.

I’ve had quite a few of these tests.

I’ve got all of the tiny lights so far.

You pop your face into the machine and then you focus on the central dot. Without moving your eyes from this position, you then tell the nurse how many little white dots you can see.

What is an Autofluorescence Test?

Posted on by One Vision
Autofluorescence is the concept of using naturally occurring fluorescence from the retina to provide an overall picture, literally, of eye health.
Illuminating the retina with blue light causes certain cellular components to ‘glow’ without injecting any dye. This glow (fluorescence) returning from the retina can be used to create a black and white image which can be interpreted by the eye specialist by seeing any characteristic and common patterns in eye conditions.
Autofluorescence patterns may be linked to disease progression in patients with macular dystrophy and may thereby help consultants determine clear diagnosis and condition of eye health.
Use of this imaging is being used in a variety of retinal diseases including: age-related macular degeneration, retinitis pigmentosa and macular dystrophies.
I haven’t had this done yet. I have will be very interesting to see what’s in there.
Just looks like a black and white photograph. I won’t pop a photograph up. Looks a bit grim.

What is an ERG Test?

Posted on by One Vision
An electroretinography (ERG) test, also known as an electroretinogram, measures the electrical response of the light-sensitive cells in your eyes. These cells are known as rods and cones. They form part of the back of the eye known as the retina.
Haven’t had one of these tests yet. Sounds intriguing.
