Dilations for Diabetic Patients

Dilation is an important part of an eye exam in a patient with diabetes because it enables your Optometrist to view the inside of the eye, through a larger pupil. Drops placed in each eye widen the pupil diameter, which is the opening in the centre of the iris (the coloured part of the eye). Dilating the pupil allows more light to enter the eye the same way opening a door allows light into a dark room. Once dilated, each eye is examined using a special magnifying lens that provides a clear view of important tissues at the back of the eye.

The drops usually wear off in 4-6 hrs.It is always advised not to drive or use machinery following the eye drops because the vision/focussing is affected. Due to the dilated nature of the pupil, a patient may be a little more light sensitive in bright conditions and so it is advised that sunglasses are worn.
