The Snellen chart

When I have this test, I’m told to leave my distance glasses on. If I’m struggling, the nurse gives me pinhole glasses which help focus the eye through tiny holes.

The Snellen chart is printed with eleven lines of block letters. The first line consists of one very large letter, which may be one of several letters, for example E, H, or N.

Only ten letters are used C, D, E, F, L, N, O, P, T, Z.
Subsequent rows have increasing numbers of letters that decrease in size. A person taking the test covers one eye from 6 metres or 20 feet away, and reads aloud the letters of each row, beginning at the top. The smallest row that can be read accurately indicates the visual acuity in that specific eye.

My Hospital Appointment – Autofluorescence Test

Well, I’ve been to the first of my appointments this week and it was for autofluorescence.

So, now I can tell you what happens.

You have the eye drops to dilate your pupils. Then wait awhile for it to take affect.

It basically is popping your head upto a machine and then you focus on a little light by the side of it and then lots of flickering bright lights flash to take the photograph of the back of your eye. Each eye in turn.

So, my macula has been photographed now and will get the results when I go back to see the consultant in a few months.

If you go for this, don’t drive there and take someone with you if possible.

The light leaves your eyes with bright patches. The disc that I can only see at night was more pronounced masking my vision.

My right eye hurts slightly now. This is several hours later. This eye was the most uncomfortable because it\’s my worst eye. My left eye was and is fine with the procedure.
