More about the lifelikeinc.com expertsCataract (Cataract) is an eye disease in which the otherwise clear lens becomes increasingly clouded. The vision decreases steadily. Often, cataracts are age-related. He can also have other triggers. These include, for example, metabolic diseases as well as malformations and injuries of the eye. With surgery, cataract can be treated well. Left untreated, it can lead to blindness. Read here which signs of cataracts indicate the role of age and why sunglasses may prevent cataracts.

ICD codes for this disease: ICD codes are internationally valid medical diagnosis codes. They are found e.g. in medical reports or on incapacity certificates. H28H25Q12H26

"If you have a cataract, look for your symptoms, and if you have severe glare sensitivity, blurred vision, and trouble driving, think of a cataract operation."

Quick Overview

  • Causes: Age, genetic factors, other diseases (eg diabetes mellitus), eye inflammation, injury or malformations
  • Diagnosis: u. a. Patient interview, eye test, various examinations of the eye by means of light (Brückner text, slit lamp)

Cataract: symptoms

If the gaze worsens and the world seems to vanish behind a veil, this could be a sign of the eye disease cataract. "Gray" because the lens turns grayish in advanced disease. The name suffix "Star" is derived from the rigid look that sufferers have when they are (almost) blinded by the eye disease.

  • Cataract: "Eyecheck once a year"

    Three questions

    Does every (age related) cataract get?

    Dr. med. habil. Wolfgang Herrmann

    An increasing cloudiness of the lens is part of the aging process. Ophthalmologists only speak of a "cataract" when visual opacity diminishes and the quality of vision deteriorates due to the cloudy lens. Illnesses such as diabetes, an unhealthy diet or smoking can cause the lens to cloud more quickly. Even UV light favors a cataract - a pair of sunglasses can protect here.

    Can I test myself if I have a cataract?

    Dr. med. habil. Wolfgang Herrmann

    Those affected often notice that they see worse or are blinded at night while driving a car. Even colors are perceived differently. These are all vision problems that can be caused by other eye diseases. That's why you should go to the ophthalmologist. Only he can certainly recognize a cataract. My advice: Older people should have their eyes checked once a year.

    How fast does surgery have to be done?

    Dr. med. habil. Wolfgang Herrmann

    In general, the cataract is then operated on, if you have problems in everyday life, or see too bad to still be able to drive. But do not worry: With over 700,000 procedures a year, cataract treatment is one of the most common surgeries. And because the methods continue to improve - you can also correct refractive errors - most of them can operate sooner rather than later.

    Herrmann heads the Eye Clinic at the Hospital of the Brothers of Charity in Regensburg. His specialties include refractive surgery for vision defects and the treatment of retinal diseases.

Depending on the stage, cataract causes different symptoms. At the beginning of the disease the sight deterioratesBe affected increasingly sensitive to blinding, In the middle of the field of vision arises a kind fogthrough which objects are blurred or perceived as behind a veil.

This mist becomes denser over time and spreads to the entire visual field as the disease progresses. Colors, contrasts and contours fade gradually and seem to merge with each other. Spatial perception and thus orientation skills are worsening.

Often sufferers ignore the symptoms first, overplay them or attribute them to other causes such as tiredness. Especially when Gray age starSymptoms that develop as a result of the normal aging process, symptoms are often attributed to the age-related decline in the eyes and not to a manifest eye disease such as cataracts.

How the picture changes with cataractsThe opacity of the eye lens means that colors, contrasts and contours of objects can no longer be perceived so well.

Individual and complete failures of the field of vision, as they occur in the case of the glaucoma, do not exist with the cataract.

Cataracts: symptoms during the course of the disease

As the disease progresses, symptoms of cataracts can become more severe in everyday life. This includes:

  • significant glare sensitivity (eg in bright sunlight or flashlight)
  • indistinct visual perception
  • worse light-dark adjustment
  • Effort while reading or watching TV
  • limited spatial vision
  • Uncertainty in traffic

These symptoms may vary in each patient. You do not necessarily have to (all) occur.

Cataracts in the late stages makes a normal everyday life almost impossible: the visual performance can deteriorate so dramatically in a short time that it amounts to blindness.

If cataracts affect both eyes, it is often difficult for sufferers to assess how far advanced their vision is. This becomes dangerous in traffic, for example.

Cataract: Relatives should be alert for signs

Precisely because those affected often misjudge or deny vision loss, it is important that relatives know and correctly interpret cataracts. In the early stages of the disease, those affected become more insecure with their usual activities, for example while driving or reading. You can tell by the fact that the patients often show a strained facial expression.

In later stages, the deterioration of vision can be so bad that sufferers are often wrong, if you give them something or want to take something into their own hands. In addition, they take a long time to find their way around an environment in which they are unfamiliar. Therefore, they often avoid foreign and unknown regions. Even in your own home environment, orientation becomes more difficult. Most people with cataracts tend to keep a close eye on things, so that they can find everything without full eyesight.

Congenital cataract: symptoms

Children can also get cataracts. Physicians then speak of the infantile or congenital cataract. The lens opacification may already exist at birth or develop during the first years of life. The first sign is often that the children start to squint.

Left untreated, the loss of visual acuity can affect the development of the visual system, which is particularly susceptible to disturbances in the first few months of life. If cataracts are not recognized and treated in the baby, it may result in a so-called low-vision (amblyopia). This can no longer be remedied at the latest on reaching puberty. Therefore, go to the doctor immediately if there are signs of cataracts in the child!
