A look into the percent change in pupil size

Looking into the percent change in eye pupil size is essential for managing the patient’s vision. By regularly tracking the eye pupil’s size, doctors can manage the patient’s treatment accordingly and improve their vision dramatically. 

The best time to track the size of the eye pupil is before the patient goes in for an examination or surgery—this way, they are prepared and know what to expect beforehand. Every person’s eye pupil size changes for different medical reasons, so it’s essential the patient gets regular monitoring. 

By tracking the size of the eye pupil regularly, doctors can also better understand the health of the iris and retina. This information can be crucial in managing the patient’s vision and improving their quality of life.

How do doctors measure the percent change in pupil size?

If you’re experiencing blurred vision or night blindness, make an appointment with your doctor and ask about measuring your eyes’ pupil size. 

The percent change in eye pupil size can often be measured by using a pupilometer. This is an instrument that measures various eye parameters, including pupil size, and helps doctors see how tapered or dilated they are. 

The application of the pupilometer helps critical care nursing to diagnose many cases where patients appear to have abnormal vision problems. Doctors also use the dilated eye exam to check the pupil size of patients.

What is a dilated eye exam?

A dilated eye exam is an essential medical examination that allows doctors to look inside the eye using special instruments, like a pupilometer. 

This test is often used to diagnose health problems like traumatic brain injuries. If you’ve had any severe hit to the head, it is vital to get a dilated eye exam to check for a change in your vision, eye pain, redness, or difficulty focusing.

How often do patients need to get a dilated eye exam?

Keeping your eyes healthy is of the utmost importance. Dilated eye exams are an essential part of the health of your eyes, and patients should get them at least every two years. 

If there are any changes or abnormalities, it is essential to schedule a follow-up exam as soon as possible. Dilated eye exams can detect signs of brain-related diseases and head trauma. Not getting an exam on a regular basis may leave you at risk for these problems, which can cause tremendous vision loss, brain trauma, and possible loss of your eyes altogether.

What happens during a dilated eye exam?

A dilated eye exam is an important step in your eye health. It’s during this appointment that your ophthalmologist will use a device called a pupilometer to measure the size of your pupils.

If the pupilometer detects that your pupils are abnormally enlarged, this may be a sign that you require further examinations and treatment. In some cases, your ophthalmologist may also prescribe further treatment.
