Cataracts

Dr. S.S. Gill, Consultant Ophthalmologist

Ipoh Echo’s eye health series continues with Consultant Eye Surgeon Dr. S.S. Gill talking to us about Cataracts.

Cataracts may cause a variety of symptoms. Blurry vision at any distance is the most common symptom of cataracts. Your vision may look foggy, filmy, or cloudy. Over time, as the lenses become more opaque or mature, less light reaches the retina. People with cataracts may have an especially hard time seeing at night making it difficult when driving. The lights from oncoming cars may scatter and cause glare.

A common complaint among housewives is that colours seem washed-out and dull. One patient who recently had her cataracts removed, actually asked her brother whether he had repainted his car white because she thought that his car colour was brown in the past! A maturing cataract makes it difficult to especially distinguish blue colours.

“Second-Sight of Aging”

There is a phenomenon called “second sight of aging” in which paradoxically a person’s reading vision suddenly improves as a result of their increased nearsightedness from swelling of the cataract. You may sometimes hear people actually boasting that they do not need reading glasses anymore to read their daily newspapers. Often this so called improved vision for nearsightedness is usually short-lived. It actually is a symptom of a maturing cataract.

Frequent Change of Spectacles

If you find that you have been needing to change prescription spectacles every few months, this too may be a symptom of cataracts. Essentially, the spectacle powers or contact lens powers will have to be increased in order to get acceptable vision to the patient.

The Unnoticed Blurring Vision

There are some patients who do not notice their blurring vision because the cataract is more mature in only one eye. This is because the other eye compensates for the vision requirement for their daily activity. The blurring vision is only noticed when they check the vision of each eye separately, only to be surprised that vision in one eye (with cataract) is so poor!  Rarely do cataracts cause double vision (also known as diplopia). As the cataract becomes more mature, the double vision may go away.

Cataracts usually progress gradually and are not painful. They only become painful when they are extremely advanced or mature resulting in a condition called glaucoma where the eye pressure increases. Therefore it is important not to wait for the cataract to be too mature before seeking eye treatment. Rapid or painful changes in vision are suspicious of other eye diseases and should be evaluated by an ophthalmologist. Take note of any unusual eye symptoms and get your eyes checked annually if you are above 40 yeas of age.

Dr. Gill will discuss more on cataracts in the next issue.

Ipoh Echo’s Eye Health Series continues with Consultant Eye Surgeon Dr. S.S. Gill talking to us about Cataract.

The lens in our eyes plays a crucial role in vision. This lens is transparent, crystalline and focuses light on the back of the eye (retina). When this crystalline lens becomes cloudy, it is called a cataract which is most commonly seen in the elderly.

When the lens becomes a cataract, it affects vision in some way or the other, either in the loss of clarity or quality of vision. This is because cataracts block and distort the light that has to pass through the lens, causing visual symptoms.

In Malaysia, cataract is the leading cause of poor vision in patients above the age of 55 years. Cataracts usually occur very gradually although there are instances it may occur rapidly.

Quite often, people may be unaware that they have cataracts because the changes in their vision have been gradual. Cataracts commonly affect both eyes, but it is not uncommon for cataracts to advance more rapidly in one eye.

What are some common causes of cataract?

Contrary to popular belief, cataract is not caused by reading or eye strain. It can be described in terms of the cause as follows:

Aging:  This is the commonest cause for cataracts developing. Almost every person will develop a cataract at some stage of life because everyone is constantly aging. Most individuals will have cataracts by the time they reach their seventies.

Secondary cataracts. These occur due to medical conditions, like diabetes, or to exposure to toxic substance and certain drugs like corticosteroids or diuretics, radiation and ultraviolet exposure. Other factors that can increase a person’s risk of developing such cataracts include air pollution, and heavy alcohol consumption.

Traumatic cataracts. These form as a result of an eye injury. At times the injury may have occurred much earlier and you may have even forgotten about it. If you do remember any history of trauma, it should be highlighted to your eye doctor.

Congenital cataracts. Babies are sometimes born with cataracts as a result of an infection, injury, or poor development. They may also develop during childhood.

Most cataracts develop slowly and don’t disturb your eyesight early on. But with time, these cataracts will eventually interfere with your vision. Congenital cataracts have to be treated early to avoid permanent loss of vision that cannot be reversed later on.

In the initial treatment of cataracts in adults, stronger lighting and stronger powered spectacles may be able to help you deal with cataracts. But if the impaired vision interferes with your usual activities, you may need cataract surgery. The good news is that cataract surgery is generally a safe and effective procedure.
