Crome syndrome

Crome syndrome: Introduction

A cataract is a common condition that affects the eyes and results in a gradual deterioration of vision. More than half of people who reach age 80 have had a cataract. Many of these people have had surgery to correct the cataract, which restores good vision in almost all cases.

A cataract is a clouding of the lens of the eye. There are different types of cataracts, including congenital cataract, secondary cataract, and traumatic cataract. The most common type of cataract develops as a person ages. With age-related cataracts, clouding of the lens of the eye generally begins when a person is in their 40s or 50s. This usually happens to both eyes at the same time. Over the years, the clouding gradually worsens and begins to stop some light rays from passing through the lens.

Early in this process, there may be no symptoms. As cataracts progress, symptoms appear and gradually get worse. They include blurred vision, distorted vision, and sensitivity to light. For more information on symptoms, refer to symptoms of cataracts.

Cataracts can affect anyone, but some factors may contribute to the risk of developing the condition. These include smoking, uncontrolled diabetes, advancing age, excessive exposure to sunlight, long-term use of corticosteroid drugs, and exposure to ionizing radiation.

Cataracts are diagnosed through a combination of taking a thorough medical history, including symptoms, and eye examination by a specialist in eye care, called an ophthalmologist. The eye examination includes using eye drops to enlarge the pupil of the eye so the ophthalmologist can look directly into the eye with an instrument called an ophthalmoscope. He or she will also examine the lens of the eye using a slit lamp. These procedures are painless and can help the ophthalmologist to diagnose cataracts, as well as their size, location, and type. Visual acuity, or sharpness of vision, will also be tested by having you read an eye chart located at a specific distance across the room.

Because there are often no symptoms of cataracts in their early stages, a diagnosis can be delayed or missed. For more information on misdiagnosis, refer to misdiagnosis of cataracts.

In their early phases of a cataract, treatment may only involve using reading or prescription glasses and magnifiers, and ensuring that lighting is bright enough to see well. As cataracts progress and symptoms can no longer be addressed by these measures, cataract surgery may be an option. Cataract surgery is very effective in restoring vision for the vast majority of people. For more information on treatment, refer to treatment of cataract. ...more »

There are often no symptoms in the earliest phases of the development of a cataract.

The first step in the treatment of cataracts is prevention. To best minimize the risk of developing cataracts, it is important not to smoke and to wear sunglasses that protect from UVB rays when out in the sun. Prevention also includes eating plenty of fruits and vegetables and effectively managing any chronic conditions, especially diabetes.

Crome syndrome: Misdiagnosis

Because most people have no symptoms of cataracts in the early stages, a diagnosis is easy to miss or delay. When symptoms do appear, such as distorted vision, a diagnosis of cataracts can also be delayed because it may be assume that the symptoms are a "normal" part of aging.
