You may need to have drops put in your eyes to dilate your pupils. It will take 20-30 minutes for your pupils to fully dilate. The drops can
make your vision blurred for 2 to 24 hours and so it is recommended that you do not drive. It is therefore important that you make appropriate transport arrangements.
You will be asked to sit at an instrument similar to the one the doctor has used to examine your eye. The imaging normally takes between 10 and 20 minutes.
Some patients will need to have an examination with a contact lens. If this is required, local anaesthetic drops will be used to numb the front of the eye. The drops will last for about 20 minutes.
Some patients will need to have a special-coloured eye drop added prior to imaging. This will not change your vision or have any long-lasting effect.
