Common Eye Diseases and Early Detection

As the population gets older, more people are losing their vision due to some of the common eye diseases. The National Eye Institute (NEI) and the CDC say that about 4.2 million Americans aged 40 or older are either blind or have low vision. This means around 1 in 28 people. By 2050, the number of people with vision problems or blindness in the United States is expected to double to over 8 million.

Why is Early Diagnosis of Common Eye Diseases Important?

One of the main reasons to have an eye exam is to keep your eyes healthy. Many people think eye exams are just for getting a new prescription for glasses or contacts. Seeing clearly with the right prescription is important but there is more to it. Eye exams help prevent or catch eye diseases early before they cause serious damage.

Many eye problems do not have obvious symptoms at first thus you might not notice them on your own. Even if you think your eyes are fine, conditions like glaucoma, macular degeneration, diabetic retinopathy, cataracts and retinal detachments can be detected during a routine eye exam. Catching these issues early will help protect your vision.

Some of the most common eye problems are as follows:

  • Keratoconus
  • Cataracts
  • Dry Eyes
  • Glaucoma
  • Diabetes
  • Macular Degeneration
  • Allergies
  • Eye Infections
  • Eye Injuries
  • and more

How the Tests Work to Detect Eye Disease?

Most eye diseases are found by noticing small changes in the eye's appearance and structure. During an eye exam, doctors often use a slit lamp microscope to look at the front of the eye and an ophthalmoscope to see the back. They usually dilate the eyes to get a better view because, without dilation, the pupil shrinks from the light used in the exam which makes it hard to see inside.

Dilating the eyes can be uncomfortable which causes blurred vision and sensitivity to light for hours afterwards. Fortunately, modern tools like digital retinal cameras, wide field retinal scanning (Optos) and Optical Coherence Tomography (OCT) offer a clear view inside the eye without needing dilation. These tools make the exam more comfortable and help doctors detect eye diseases more accurately.

Digital images from these tools are especially helpful in tracking changes over time which is important for managing conditions like macular degeneration, glaucoma and intraocular tumors. These images should be part of your medical record as they provide valuable diagnostic information that cannot be obtained otherwise. 

Wide Field Retinal Imaging

Standard digital retinal cameras can take great images of the central retina in most eyes. However, if a patient’s pupils are too small, dilation may still be needed to get a clear image.

Wide field scanning laser ophthalmoscopy provides a much wider view of the inside of the eye. This helps doctors detect tumors, retinal detachments, bleeding or other eye diseases that might be missed with other exam methods including standard digital imaging. This tool requires a smaller pupil size to capture images which can help avoid the discomfort and side effects of eye dilation.

Advanced Intraocular Pressure Management

Glaucoma diagnosis and treatment often rely on measuring and adjusting the fluid pressure inside the eye. This is done using either contact or non-contact methods. Contact tonometry uses a probe to press on the eye while non-contact tonometry uses a puff of air to measure the eye's response.

Recently, non-contact tonometers have been developed that can measure more than just pressure. They can also account for factors like corneal thickness and rigidity which can affect pressure readings. Previously, it was assumed that all eyes had the same rigidity but new technology can now adjust for this which leads to more accurate measurements and better diagnoses. 

Visual Field Testing

Visual field testing helps detect glaucoma, retinal disease, optic nerve disease and even brain tumors. The test is painless and takes only a few minutes. The patient sits comfortably at a machine that shows a series of light stimuli and presses a button when they see them. These lights vary in brightness or contrast to map how well the patient can detect light. Diseases affecting the optic pathway often create distinct patterns that doctors can evaluate. Some eye doctors may skip this test or charge extra for it but you can visit EMC for affordable tests.

Intraretinal Imaging

Optical Coherence Tomography (OCT) is a modern technology that will let doctors see detailed cross sections of tissue with high precision. It provides a close look at the retinal nerve layers which helps diagnose glaucoma and macular degeneration. OCT can also be used for other conditions but it is especially useful for these two. 

Conclusion

As you get older, many factors can impact your vision thus it is important to have eye exams regularly. You should get your eyes checked every year or every six months. If you are unsure how often you need to go, ask your doctor. Finding common eye problems early will help you see if you are at risk for conditions that might affect your vision in the future. Regular eye exams can catch issues before they become serious which helps you manage or prevent problems and keep your eyesight healthy. Taking care of your eyes now can make a big difference in protecting your vision later on.
