A girl from Puerto Rico recently asked me why the eye doctor administers of her drops to dilate her pupils during an examination. She mentioned she discovered this to be really annoying because in Puerto Rico there is a lot of sunrays and, when she went outside after the appointment of her, the light made the eyes of her hurt.

This is a very vital question and is one about which I am sure that numerous other men and women have wondered.

Since pupil dilation isn’t necessary to test visual acuity, it often is viewed as an unwanted nuisance. However, as you soon will see, this’s an indispensable tool that allows me to keep an eye on the overall health of your eyes.

I do pupil dilation for tabs examination because doing so makes it possible for me to get the best look at the back of your eye. In technical terms, this particular area is called the vitreous chamber. It’s loaded with a substance called vitreous humor.

Widening (dilating) a patients’ pupils raises the angle in which I am able to observe the backside of the eye. I examine this region by pointing a beam of light through the pupil. Ordinarily, in the presence of light which is bright, the pupils constrict to enable less light to pass through on the retina. This would create an unacceptable situation in which I just would be able to see a small thing in the rear of your eye. However, with the pupils dilated, I’m able to see a much increased region and have a better view of this area.

Once I have administered eye drops for pupil dilation, I examine the optic nerve as well as the blood vessels in your retina. Specifically, I look for changes in the optic nerve which may be an indication of glaucoma or perhaps some other eye illnesses, for instance macular degeneration. I additionally evaluate the level of the blood vessels, including how they cross each other.

Foremost among these is primary angle-closure glaucoma. In this problem, the direction created by the cornea and also the iris in the front part of the eye, referred to as the irideocorneal direction, is narrow. This can impede the normal flow of fluid, known as aqueous humor, in this area plus rapidly improve the pressure within the eye of yours.

Following an eye examination, the pupils of yours usually will stay dilated for 3 4 hours. Throughout this time, you will experience sensitivity to light and could have blurry vision, especially during other work and reading requiring close focus. Because of this, I always recommend my patients bring sunglasses with them so they are not bothered by light the moment they go outside. I provide disposable sunglasses to patients that have forgotten to take their very own, but these look like the 3 D glasses which are given away at movie theaters and aren’t especially stylish.
