Be alert to these early symptoms of glaucoma?

summary

Glaucoma is the second most common eye disease in China and the fourth leading cause of blindness. According to the epidemiological data of major eye diseases in China, the prevalence rate of glaucoma is 2.3% and the blindness rate is about 30% in the population over 40 years old, and the blindness caused by glaucoma is irreversible. With the popularity of mobile phones, computers and other electronic products, more and more young people, even children, are becoming high-risk groups of glaucoma. Be alert to these early symptoms of glaucoma? Let's talk about it

Be alert to these early symptoms of glaucoma?

The visual acuity decreased gradually. The corrected visual acuity of optometry and glasses was less than 1.0 (logarithmic visual acuity chart was 5.0). Especially for high myopia, they often had headache and swelling after wearing moderate glasses. As the sclera (white part) of high myopia becomes longer, the elasticity decreases significantly. Therefore, when high intraocular pressure occurs, the conscious symptoms are not obvious or asymptomatic, the patients are easy to neglect, but the vision is quietly lost, and the doctors are often easy to miss diagnosis.

Glaucoma patients usually drink more water, a drink more than 300 ml when headache. This is because the speed of drinking water is fast and the amount is large, which can reduce the osmotic pressure caused by hemodilution. The amount of aqueous humor entering the eye will increase, thus causing the increase of intraocular pressure. Patients often have eye distension and headache 15-30 minutes after drinking water.

After getting up in the morning, it's hard to read, and it's easy to have acid swelling at the root of the bridge of the nose and swelling pain at the orbital forehead. Because normal people's intraocular pressure fluctuates day and night, generally high in the morning and low at night. Glaucoma patients 24 hours of intraocular pressure fluctuations are greater, so the morning intraocular pressure is higher, there will be symptoms.
