Cataracts – Importance of Diagnosis, Types and Symptoms

Types of cataract and the symptoms to watch out for

Cataracts cloud the natural lens of the eyes in the form of protein build-up. Global statistics indicate that cataract is the cause for blindness among 20 million people in the world. This roughly translates to about 51 % of all cases of blindness. In India, this percentile of blindness caused by cataract runs higher to 62.6 %.

Here’s a rundown of the types of cataract and the symptoms to look out for.

Types of Cataract

The two broader categories:

Acquired Cataract: This form of cataract can be an age-related affliction, the result of other medical conditions such as diabetes, or the result of eye injuries. It could also stem from being around radiation, ultraviolet light, toxic substances, or due to in-take of certain medication like corticosteroids or diuretics.

Congenital Cataract: Babies are sometimes born with cataracts. The possible causes for the condition include injury, infection, or poor development in the womb. They can also form during childhood.

Signs and Symptoms of Cataracts

Different types of cataracts could exhibit different symptoms. This includes:

Blurry Vision: Cataracts form over a period of time and it will be a while before you notice the symptoms. But blurred or cloudy vision is among the first things you will notice.

Light Sensitivity: Light from a lamp or sunlight can seem brighter to the point of seeming glaring. There’s also the effect on night vision, where some activities can prove difficult for you. For example, while driving the glare of headlights can be overwhelming for your eyes.

Seeing Halos: When the cataract clouds your lens, it can lead to diffraction of light entering the eye, which can cause you to see rings or halos around light sources. You may even see rings in various colours around lights.

Trouble Reading: Some types of cataracts start at the back of the lens. This can block the path of light and it often interferes with your reading vision.

Frequently Needing New Glasses or Lenses: If you have erratic eyesight, where you need stronger glasses often, you may want to see an ophthalmologist. A form of cataract – the nuclear cataract – also causes a temporary improvement in your near-vision before the condition worsens your vision.

Double Vision: Diffraction from lens clouded with cataract may lead to double vision, where you see multiple images of a single object. Double vision could also be a symptom of other medical conditions, and you need to see a specialist to ascertain your condition.
