Diseases of the eye aren't always heavily discussed and may be hard for some people to understand and adequately diagnose without professional help. That's where high-quality eye exams come into play. They can help a person pinpoint where a disease has started in their eye and track where it is progressing to ensure that it gets treated as effectively as possible or their needs.

Eye Diseases May Affect Many Areas of the Eye 

The eye is made up of multiple parts, each of which serves a specific task in creating vision. For example, the pupil captures light, the iris controls how much light enters the eye, and the cornea protects the interior of the eye from damage. However, a disease in one part of the eye — such as an infection — may spread rapidly to other areas and cause more persistent and damaging issues.

For this reason, eye exams are so diverse and widespread in what they track. Their main goal is to ensure that disease is quickly diagnosed and the proper treatment chosen to manage its spread. Thankfully, a large number of exams a person can consider if they start to feel pain in their eyes, notice vision loss, or any other troubling symptoms with their vision.

Types of Eye Exams to Consider 

Many types of eye exams can test each area of the eye to ensure that any issue affecting it is appropriately managed. For example, applanation tonometry helps track glaucoma progression throughout the cornea and makes this disease ether to track. And corneal topography also tests the cornea but is better for monitoring diseases like astigmatism of the eye.

Some tests can track the optic nerve's ability to transmit visual information properly and make sure it isn't affected by any swelling or other pain types that may cause damage. Typically, an eye doctor goes through multiple eye exams to track the progression of a disease and provide a standard vision test to see if a person needs any corrective lenses for their eyes.

As a result, it is good to investigate these eye exams before talking to an optometrist. These experts can figure out what type is best for a person's needs and give them the detailed and effective treatment that they need to manage these issues and protect their vision from any unnecessary damage at the same time. It is a win-win for all involved in this process.
