Cataract, as one of the most serious diseases affecting vision, is not only harmful to the health of the elderly, but also has a very serious impact on the vision of many young people. What do you know about cataract? In the development of cataract, there will be different symptoms. Now let's take a look at the related knowledge of cataract.

What are the symptoms of cataract in teenagers?

At first, a radial milky white wedge-shaped opacity appeared in the equatorial cortex of the lens. Its base was at the equatorial part, and its tip was toward the center of the pupil. The cortex between the cloudy stripes was still transparent. After mydriasis, black wedge-shaped shadows appeared on the red background of the equatorial part of the lens by the penetration method. The peripheral part of the opacity was feathery by the slit lamp microscope, In the early stage, the development of turbidity is very slow, up to several months or even years, and some stay in this stage for a long time without development.

The wedge-shaped opacity in the equatorial part of the lens gradually expands and continues to develop to the pupil area and deep layer. The whole lens appears milky white opacity, but the opacity is not uniform. After the original wedge-shaped opacity fuses with each other, the radial stripes can still be clearly displayed. At this stage, the water content in the cortical layer increases and the lens expands, the anterior chamber becomes shallow, and secondary glaucoma may occur, Because the cortex is not completely turbid, iris projection exists.

The lens cortex was completely turbid, the appearance was diffuse milky white, the lens expansion completely subsided, the anterior chamber depth returned to normal, and the iris projection did not exist. The protein denaturation of lens cortex continues to develop, the fiber structure has been completely destroyed, the radial stripes disappear, and the lens presents uniform white turbidity. Due to the continuous discharge of decomposition products and water, the anterior chamber becomes deep, the iris vibrates, and the anterior capsule becomes turbid and wrinkled. The time from the initial stage to the mature stage varies from person to person, generally ranging from 5 to 10 years.
