Diagnosing and Treating Cataracts

Cataracts are an age-related eye condition that mostly affects people over the age of 60. The eye lens is the clear structure that helps to focus images on the retina. A cataract develops when this lens becomes cloudy. This block or distorts the light passing through the lens, resulting in cloudy vision. The condition usually takes years before the lens becomes cloudy. It may not affect an individual’s vision for years after the initial onset.

 

Causes of Cataracts

Cataracts are a leading cause of blindness, and they can occur due to different reasons. Some people get cataracts due to an eye injury. Other causes include diabetes, the effects of corticosteroid medication, and radiation therapy. Cataracts normally affect elderly people, but kids can also get cataracts. Some babies may be born with cataracts, while others develop them due to an infection during pregnancy. Cataracts in young children and infants can be symptoms of various diseases.

 

Symptoms of Cataracts

Cataracts do not often present symptoms in the early stages. The symptoms occur when cataracts have grown, and they begin to interfere with the vision. Symptoms include blurry or cloudy vision and increased sensitivity to light or glare. It also includes double vision and colors appearing faded. Patients also report difficulty with night vision and seeing halos or spots around lights. Anyone experiencing any of the symptoms should visit a doctor for a proper diagnosis.

 

Diagnosing Cataracts

As part of the diagnosis, the eye doctor will usually ask for a history of the visual symptoms. This is followed by an examination that includes dilating or widening the pupils using medication. A visual acuity test is carried out to check the vision. Cataracts can be diagnosed using a retinal exam or visual field testing. Also, a comprehensive exam with dilation or using the slit-lamp examination are other methods. An ophthalmologist or optometrist performs the examination. Here, a high-intensity light is used alongside a low-powered microscope to identify cataracts.

 

Treating Cataracts

Individuals who have cataracts can benefit from using magnifying lenses or prescription eyeglasses. Some people turn to stronger lighting as a way to improve their vision. Before seeking invasive treatment, it is important to think about the risks and benefits. Cataract surgery is often used to treat cataracts. During surgery, the clouded lens is removed, and a plastic lens is inserted to replace this damaged lens. Cataract surgery can help to improve a patient’s vision.

 

Screening Exams

It is recommended that patients who may have cataracts get regular eye exams. Cataracts often occur alongside other conditions. It is important to visit an optometrist and to have screening exams every year. People who have diabetes or active cataracts may require more frequent screening. Many patients require multiple adjustments of their glasses because of vision changes. An optometrist may recommend glasses with an anti-glare coating to reduce sensitivity to light.

 

There are things that someone with an eye condition can do to get some relief from the symptoms. Some tips include improving lighting around the home, wearing sunglasses while outdoors, and avoiding or limiting night driving. People who have concerns about cataracts or their eye health should visit an optometrist regularly.
