What are the symptoms of senile cataract and how to treat them

summary

With the development of society and the progress of the times, although the life of the elderly is getting better and better, there are more and more kinds of senile diseases. In addition to presbyopia, many elderly people seem to be covered with a layer of fog and white when they see things, and sometimes they will always see some virtual shadows. This is the symptom of senile cataract. Senile cataract is the result of many factors As a result, many times it is related to aging and heredity. This disease is not only common, but also the treatment method is very simple. Now there are many treatment methods. The following will introduce the symptoms of senile cataract and how to treat them.

What are the symptoms of senile cataract and how to treat them

1. Cortical age-related cataract: cortical cataract is the most common type of age-related cataract, which is characterized by turbidity from the peripheral superficial cortex, gradually expanding to the center, occupying most of the cortex. According to its clinical development and manifestation, cortical cataract can be divided into four stages: initial stage, progressive stage, mature stage and over mature stage.

2. Nuclear age-related cataract: initially, the opacity appears in the embryonic nucleus, then extends outward until the old nucleus. In the process of nucleus opacification, the color of lens changes. In the early stage, a small amount of brown pigment only accumulated in the nucleus, but not extended to the cortex. When the pigment accumulation is less, the core is pale yellow, which does not affect the vision, and the fundus is clearly visible.

3. Subcapsular opacification cataract: opacification is mostly located under the posterior capsule, which is brown fine granular or shallow cup-shaped vesicle. When examined under slit lamp, it is sometimes found that the capsule near the turbid area is involved, showing yellow, blue, green and other reflections, forming the so-called colorful flash phenomenon. Because the lesion is closer to the node, even if the course of disease is early, or the lesion is small and light, it will cause serious visual impairment.

matters needing attention

One treatment method is drug therapy, including sulfur-containing preparation, anti quinone preparation, aldose reductase inhibitor, vitamin and energy mixture, natural extract, etc., such as farcolin, glutathione, vitamin C, senolint, baineting, etc. Local or systemic treatment is available. Another treatment is surgery, which is the most basic and effective method to treat cataract. At present, phacoemulsification combined with intraocular lens implantation technology is mainly used.
