One, What is macular edema?
Macular edema is caused by the destruction of the blood-retina barrier of the retina, resulting in leakage of capillaries, and the leakage of fluid in the macular area, forming macular edema, including macular cystoid edema (CME) and macular diffuse edema (DME).
Two, Etiology and clinical manifestations:
1. Almost all inner eye surgeries are likely to be followed by laser photocoagulation and condensation surgery. The peak of cataract surgery is about 6-10 weeks after surgery. The incidence increases with surgical complications such as wound vitreous incarceration, iris detachment and vitreous prolapse.
2, central vision slowly decline, there may be relative or absolute central scotoma.
3. Fundus fluorescence angiography is very valuable for the diagnosis of macular cystoid edema: the cystoid edema area blocks the choroidal background fluorescence in the early stage of angiography, so there is a large dark area within the scope of macular edema.
Iii. Treatment methods
Laser therapy and drug therapy are the main treatments.
1. Drug treatment:
Fundus microcirculation improvement agent
vitamin
2. Laser treatment.
4. Preventive care
1, because vegetables and fruits contain a large number of antioxidants, such as trace elements, vitamins, lutein, etc., therefore, it is recommended to eat more vegetables and fruits. Fish contains a large amount of unsaturated acid, has a strong antioxidant capacity, it is recommended to eat more.
2. Studies have shown that the occurrence of macular degeneration is related to high blood pressure and hyperlipidemia, so it is necessary to actively prevent high blood pressure and hyperlipidemia, eat less greasy food, and strengthen exercise to help prevent macular degeneration or slow its development.
3, smoking and the occurrence of macular degeneration has a very clear correlation, therefore, it is recommended to quit smoking.
