What Are the Major Types of Cataracts

What Are the Major Types of Cataracts?

• Nuclear sclerotic cataracts. A cataract appears in the center of the lens. In the beginning, it seems like aggravated myopia. Thereafter, the color of the lens turns yellow and then brown. In severe cases, the vision weakens to an extent that patients can no longer distinguish different shades of color.

• Cortical cataracts. A cataract shows up in the periphery of the lens. The color of the lens in the periphery turns cloudy, and white, wedge-like opacities gradually migrate to the center of the lens. At this stage, patients generally avoid glaring lights.

• Posterior subcapsular cataracts. A cataract appears in the posterior region of the lens. The color of the lens in the posterior region turns cloudy. Patients have blurred vision that interferes with reading and driving.

• Congenital cataracts. A cataract develops when the fetus is still in the mother's womb. Infants whose mothers were infected with German measles during pregnancy could be afflicted with congenital cataracts in childhood.
